Description

  The present invention relates to a stereoscopic video output device, and more particularly to a stereoscopic video output device having a stereoscopic video display function.

  In recent years, thin display devices typified by liquid crystal televisions have a 3D image display function (hereinafter also referred to as “3D display”), which was previously installed only in some high-end models, and is also installed in popular models. It has become so. With the enhancement of 3D content, BD players and the like are also compatible with 3D display on many models.

  Under such circumstances, various user-friendly presentation means technologies that can recognize the state of 3D display have been proposed. For example, there is a technique for displaying a selected image on a display unit after giving a warning that the displayed image is a stereoscopic image (see, for example, Patent Document 1). Specifically, an image is selected in order to display the image data recorded on the recording medium on the display means, and it is determined whether the selected image is a planar image or a stereoscopic image. When the determination result is a three-dimensional image, the sound generation unit, the vibration generation unit, the light generation unit, and the like are notified to that effect.

  As another technique, a technique is disclosed in which an observer can easily recognize whether a video displayed on a video display unit is a stereoscopic video or a flat video (for example, Patent Documents). 2). In this technology, the stereoscopic video display device has an input signal determination circuit that determines whether the video signal is for displaying a stereoscopic video, mixes a character signal for mode display with the video signal according to the determination result, and A three-dimensional display mark is displayed on-screen as a mode display on the display unit.

  In addition, liquid crystal television products that are provided with display means such as LEDs in the frame portion of the liquid crystal television to display a 3D viewing state by turning on / off are also on the market. If the screen is 3D video, the 3D status display unit is lit, and if it is not 3D video, the display unit is turned off.

  By the way, in the technique disclosed in Patent Document 1, it is assumed that image data recorded on an HDD or a detachable recording medium is reproduced on a 3D monitor of a lenticular lens type. An object is to warn in advance that a 3D image is displayed and to reduce a user's psychological shock due to the sudden appearance of the 3D image. Further, with the technique disclosed in Patent Document 2, only an OSD on the screen is warned that it is a screen 3D video. Therefore, it may interfere with the display on the screen and reduce the display quality. In addition, in a product having a 3D state display unit that indicates a 3D viewing state by turning on / off (or lighting of another color), if the screen is in a 3D video state, the 3D state display unit is lit, and if the screen is not 3D video The display section is monotonously classified as unlit (or lit in a different color). Here, when the display image is 3D, it is assumed that the display unit is turned on and the user is encouraged to wear 3D glasses. However, in the first place, most users are 3D images when viewing the screen image. It seems that there are many cases that can be distinguished. That is, even if the status display section is provided, it cannot be said that it is fully utilized, and another technique has been demanded to utilize it.

  Next, modes for carrying out the present invention (hereinafter, simply referred to as “embodiments”) will be specifically described with reference to the drawings.

<First Embodiment>
A liquid crystal television will be described as an example of a stereoscopic video output device having a 3D display function in the present embodiment. Regarding 2D and 3D video display on this liquid crystal television, (1) 3D signal reception → 3D video display, (2) 3D signal reception → forced 2D video display, (3) 2D signal reception → 2D video display, (4) 2D There are four modes: signal reception → pseudo 3D video display. Therefore, the liquid crystal television first determines a signal type of an input signal (original signal) from a broadcast wave or a peripheral device (external input device), and the original signal is a 3D display signal (hereinafter simply referred to as “3D signal”). Or 2D display signal (hereinafter simply referred to as “2D signal”). Subsequently, it is determined whether or not the display state of the screen is 3D screen display. Then, an illumination display is performed on the state display unit arranged in the outer frame portion of the display panel of the liquid crystal television so that the relationship between the signal type of the original signal and the display state can be determined. Details will be described below.

  FIG. 1 is a front view of a liquid crystal television 10 according to the present embodiment. As shown in the figure, the liquid crystal television 10 includes a 3D state display unit 70 in a panel outer frame portion in the lower left portion when viewed from the front. The 3D state display unit 70 displays the relationship between the signal type of the original signal and the display state. The display mode will be described later. For example, if the original signal is a 3D signal and the display state is 3D display, “3D” is displayed in blue. Further, when the original signal is a 3D signal and the display state is 2D display, “3D” is displayed by blinking blue.

  FIG. 2 is a functional block diagram showing the configuration of the liquid crystal television 10 according to the present embodiment. The liquid crystal television 10 includes a source unit 20, a decode / capture unit 42, a video selector unit 44, a video processing unit 46, a display control unit 50, a liquid crystal display unit 62, a 3D glass control unit 66, and a 3D state. And a display unit 70. Furthermore, the liquid crystal television 10 includes a CPU 90 that comprehensively controls each component, a memory 92 that is a work area and a recording area, an EPG / OSD processing unit 80, a remote control receiving unit 84, and a remote controller 86. .

  The source unit 20 includes a digital reception unit 30, an external input unit 22, and a recording / playback unit 24. The digital receiving unit 30 is connected to an antenna and receives a digital broadcast. The external input unit 22 is connected to the external device 11 and acquires the content of the external device 11. The external device 11 is, for example, a BD player, a video camera, a satellite broadcast receiver, a mobile terminal, a tablet PC, or the like. The connection interface is HDMI, USB, wired LAN, WiFi or the like capable of link communication. The recording / reproducing unit 24 is a DB drive, a DVD drive, an HDD, a memory card, or the like having a recording / reproducing function.

  The digital reception unit 30 includes a digital tuner unit 32, a digital demodulation unit 34, and a separation unit (DeMUX) 36. The digital tuner unit 32 acquires a signal (modulated wave) having a designated frequency. The digital demodulation unit 34 demodulates the modulated wave signal acquired by the digital tuner unit 32 and performs processing such as error correction processing and frame reconstruction. After the processing of the digital demodulator 34, the separator 36 extracts a necessary stream from the multiplexed TS and outputs it to the decode / capture unit 42. The decode / capture unit 42 performs a decoding process according to, for example, the MPEG standard. The video selector unit 44 selects which source of the source unit 20 is to be displayed.

  The video processing unit 46 performs video, audio, and data presentation processing. That is, the video processing unit 46 adjusts the video signal, overlays the data broadcast screen on the video signal, superimposes the caption data, and performs scaling processing as necessary. When OSD (On-Screen Display) display or EPG (Electronic Program Guide) display is performed, the EPG / OSD processing unit 80 performs processing in cooperation with the CPU 90.

  The display control unit 50 includes a 3D processing unit 52, a 3D-2D conversion unit 54, and a state display setting unit 56. If the original signal is a 2D signal and the output remains in 2D display, the display control unit 50 outputs the signal acquired from the video processing unit 46 to the liquid crystal display unit 62. When the original signal is a 3D signal, the 3D processing unit 52 performs processing suitable for the 3D signal. That is, the 3D processing unit 52 generates a right-eye video and a left-eye video, and outputs them to the liquid crystal display unit 62. In general, a user can grasp a three-dimensional image by wearing a 3D glass equipped with a right-eye shutter and a left-eye shutter, and viewing the image in synchronization with the image. The 3D glass control unit 66 performs synchronization processing with the 3D glass. There are various types of 3D processing, but in this embodiment, any type of 3D processing may be used, and there is no particular limitation.

  The 3D-2D conversion unit 54 generates a 2D signal and outputs it to the liquid crystal display unit 62 when the original signal is a 3D signal and 2D is selected as the output state.

  The state display setting unit 56 controls the display of the 3D state display unit 70 and sets and records the user setting of the illumination display function. Whether or not the original signal is a 3D signal may be determined by analyzing the signal itself, or may be determined by referring to a flag or the like indicating the 3D signal included in the signal.

  The liquid crystal display unit 62 includes a liquid crystal panel and a panel controller that drives the liquid crystal panel.

  As described above, the 3D state display unit 70 is a display unit configured by an LED or the like provided independently of the liquid crystal display unit 62, and the relationship between the original signal and the output state is displayed in a predetermined display mode. Illumination display. Further, the type of source of the original signal is also reflected in the illumination display. For example, when displaying the content of the external device 11, the liquid crystal television 10 can determine whether the original signal from the external device 11 is a 3D signal and whether the display state on the liquid crystal display unit 62 is 3D display. Illumination display in the 3D state display unit 70 is performed. The illumination display function can be set by the user, and can be selected, for example, from “always off”, “automatic (on)”, or “manual” on a predetermined menu screen. In the case of “always off”, it is not displayed on the 3D state display unit 70. In the case of “automatic (on)”, the 3D state display unit 70 automatically determines the original signal and the display state as described above, and performs illumination display according to the determination result. In the case of “manual”, 3D illumination display is performed only in response to an operation such as a user pressing a predetermined button on the remote controller 86.

  A specific operation with the above configuration will be described. FIG. 3 is a flowchart focusing on the illumination display processing in the 3D state display unit 70 when displaying the contents of the digital reception unit 30 or the recording / playback unit 24. FIG. 4 is a table showing a display pattern of the 3D state display unit 70 in that case.

  The display pattern of FIG. 4 will be briefly described. The user selects and sets the display pattern of the 3D state display unit 70 from patterns 1 to 3 in advance. Pattern 1 is set as the initial value. Patterns 1 to 3 may be fixed values or may be changeable by the user.

  When the original signal is a 3D signal and the screen display is 3D display (hereinafter referred to as “3D screen display”), the 3D status display unit 70 displays the character “3D” in color 1 (blue) in any pattern. Illumination display. When the original signal is a 3D signal and the screen display is 2D display (hereinafter referred to as “forced 2D screen display”), the 3D state display unit 70 blinks the color 1 (blue) in the pattern 1 to display the character “3D Is displayed as an illumination. In pattern 2, the character “3D” is illuminated and displayed in color 2 (red). In the pattern 3, the 3D state display unit 70 displays the character “3D” in an illumination manner by repeating the state in which the color 1 (blue) blinking state is turned off.

  If the original signal is a 2D signal and the screen display is also a 2D screen display, the 3D state display unit 70 displays the character “3D” in color 2 (white) in pattern 1 and turns off the light in patterns 2 and 3. When the original signal is a 2D signal and a 3D signal is generated from the 2D signal and the screen display is displayed in a pseudo 3D screen, in the pattern 1, the 3D state display unit 70 blinks in the color 1 (blue). In pattern 2, the 3D state display unit 70 is lit in color 3 (red). In the pattern 3, the 3D state display unit 70 repeats the change from the blinking state of color 1 (blue) to the constant lighting.

  Next, a flowchart will be described assuming that the pattern 1 is set. First, in the liquid crystal television 10, when the power is turned on, the state display setting unit 56 determines the setting state of the 3D illumination display function at a predetermined timing (S10). If the 3D illumination display function is set to “OFF” (Off in S10), the state display setting unit 56 controls the 3D state display unit 70 to be always turned off (S12). That is, the 3D state display unit 70 is not lit up regardless of whether the original signal and the display state are 3D.

  If the 3D illumination display function is set to “manual” (manual of S10), the status display setting unit 56 lights and displays the 3D status display unit 70 only in response to an operation by the remote controller 86 (S14). For example, after a predetermined button on the remote controller 86 is pressed, the 3D state display unit 70 is continuously lit or displayed for a predetermined time. The display mode may be the same as in the “automatic” setting described later (for example, pattern 1 in FIG. 4).

  If the 3D illumination display function is set to “ON” (On in S10), the status display setting unit 56 determines whether or not the signal (original signal) of the content (channel) being viewed is a 3D signal. Judgment is made (S16). When the signal is a 3D signal (Y in S18), the state display setting unit 56 determines whether the screen display is a 3D display (S20). When the screen display is 3D display (Y in S20), the 3D processing unit 52 performs 3D processing on the original signal and displays the 3D on the liquid crystal display unit 62 (S22). At this time, the 3D glass control unit 66 performs a synchronization process with the 3D glasses worn by the user. Further, the state display setting unit 56 displays the 3D state display unit 70 with the color 1 indicating that the original signal is a 3D signal and the display state is 3D display (S24).

  When the screen display is not 3D display (N in S20), that is, in the case of 2D display, the 3D-2D conversion unit 54 converts the 3D signal into a signal for 2D display and forcibly displays the 2D screen on the liquid crystal display unit 62. It is displayed (S26). At this time, the synchronization process by the 3D glass control unit 66 is not performed. Further, the state display setting unit 56 displays the 3D state display unit 70 with “color 1 blinking” indicating that the 3D signal is being forcedly displayed on the 2D screen (S28).

  When the original signal determination process in S18 is not a 3D signal (N in S18), that is, when the original signal is a 2D signal, the state display setting unit 56 determines whether or not the screen display setting is 2D screen display. (S30). In the case of 2D screen display (Y in S30), the display control unit 50 displays the 2D signal as it is on the liquid crystal display unit 62 (S32). Further, the state display setting unit 56 causes the 3D state display unit 70 to be lit and displayed in color 2 (S34). When the display is not 2D screen display (N in S30), that is, in the case of pseudo 3D screen display, the display control unit 50 generates a 3D signal from the 2D signal and displays the 3D screen on the liquid crystal display unit 62 (S36). At this time, the 3D glass control unit 66 performs a synchronization process with the 3D glasses worn by the user. Further, the state display setting unit 56 displays the 3D state display unit 70 in the color 1 blinking state indicating that the display is a pseudo 3D screen display (S38).

  When the user arbitrarily sets the forced 2D screen display state for the forced 2D screen display for displaying the 3D signal in 2D video, for example, in the recording / playback unit 24 such as a BD or HDD, “table recording” or “table recording” Even if another 3D content is to be played back during “recording and home network content recording” or “during simultaneous recording of two programs”, there is a case where forced 2D screen display is performed regardless of the intention of the user due to performance. That is, when a plurality of contents are recorded at the same time, the 3D process may not be performed due to the processing capability. In this case, for example, in addition to the above pattern, display may be performed according to classifications such as “blink with color 4 (yellow)”, “light with color 4”, and “blink with color 4 → turn off”.

  As described above, according to the present embodiment, not only the control of whether or not the display state of the liquid crystal display unit 62 is 3D video, but the 3D state display unit depends on the display state and the state of the input signal. 70, the state display part control which distinguished the state clearly by the said pattern can be performed. Therefore, for example, in the case of forced 2D screen display, it is clarified by the control of the 3D state display unit 70 that the 3D signal is originally input, and in the case of the pseudo 3D screen display, the 2D signal is originally input. can do. As a result, user convenience can be improved.

  In other words, if the 3D signal is being viewed forcibly on the 2D screen, the 3D signal is originally received as the signal. Therefore, the switching operation from the forced 2D screen display to the 3D screen display is performed by a predetermined operation. If the 3D glasses are prepared, it can be clearly noticed by the predetermined display control of the status display section that the 3D viewing can be enjoyed. Further, if the 2D signal is displayed on the pseudo screen and viewed, the 2D signal is received as the original signal. Therefore, if a switching operation from the pseudo 3D screen display to the 2D screen display is performed by a predetermined operation. The predetermined display control of the 3D state display unit 70 can clearly notify that the currently available 3D glasses can be removed for viewing.

  The display on the 3D state display unit 70 is not limited to the above-described conditions. For example, when a 3D content program is being broadcast on another channel, this may be indicated by a predetermined color or blinking state.

<Second Embodiment>
In the present embodiment, a display process of the 3D state display unit 70 when a signal is displayed on the liquid crystal display unit 62 from the external device 11 will be described. The liquid crystal television 10 has the same configuration as that shown in FIGS. FIG. 5 is a flowchart focusing on the illumination display process in the 3D state display unit 70 according to the present embodiment.

  Next, in the liquid crystal television 10, when the power is turned on, the state display setting unit 56 determines the setting state of the 3D illumination display function at a predetermined timing (S110). If the 3D illumination display function is set to “OFF” (Off in S110), the state display setting unit 56 controls the 3D state display unit 70 to be always turned off (S112).

  If the 3D illumination display function is set to “manual” (manual of S110), the status display setting unit 56 lights and displays the 3D status display unit 70 only in response to an operation by the remote controller 86 (S114).

  If the 3D illumination display function is set to “on” (On in S110), the liquid crystal television 10 is controlled to be in a standby state with the 3D illumination display function turned on (S118).

  Subsequently, when an input signal from the external device 11 is detected within a predetermined period in the standby state or by remote control operation (S118), the state display setting unit 56 determines whether or not the original signal (input signal) is a 3D signal. Judgment is made (S120).

  When the input signal is a 3D signal (Y in S120), the 3D processing unit 52 displays the 3D signal input from the external device 11 on the liquid crystal display unit 62 in a 3D screen (S122). Further, the status display setting unit 56 displays a color 5 indicating that (S124).

  If the input signal is not a 3D signal (Y in S120), that is, if it is a 2D signal, the display control unit 50 displays the 2D signal input from the external device 11 on the liquid crystal display unit 62 on a 2D screen (S126). Further, the status display setting unit 56 turns off the display (S128).

  According to the present embodiment, the liquid crystal television 10 can grasp what the original signal is when displaying the external device 11. In particular, a display unit such as a lamp of the external device 11 may not be seen when stored in a storage rack. There is also a case where there is no indication as to whether or not the signal is a 3D signal. Therefore, user convenience can be improved.

  In addition, when the external device 11 and the liquid crystal television 10 are connected so as to be linkable with an HDMI interface, the liquid crystal television 10 can grasp content information of the external device 11. Therefore, as a result of referring to the content information of the external device 11, the state display setting unit 56 can determine that the original content is 3D content but is transmitted as a 2D signal. . That is, the state display setting unit 56 can determine whether the signal acquired from the external device 11 is a 3D signal converted into a 2D signal. If the 3D signal is converted into a 2D signal, the 3D state display unit 70 may display that fact in a predetermined color. With reference to the display, the user operates the remote controller 86 so as to perform pseudo 3D display on the liquid crystal television 10 side. Note that pseudo 3D display may be automatically performed. Another example of the external device 11 is a mobile terminal such as a mobile phone or a media player having a communication function. As these communication interfaces, IP wireless communication using infrared communication (IrSS), WiFi, or the like can be used. Further, as the external device 11, there is a home network server connected via a USB memory or DLNA. Even when the content of the still image or moving image acquired from these external devices 11 is 3D content, the 3D state display unit 70 may display the image in a predetermined color. In addition, content that has a large recording size and takes a certain amount of time to receive may be displayed in a predetermined display form so that it can be seen that 3D content is being received even before playback is started. Moreover, it may be displayed so that it can be recognized whether it is a still image or a moving image.

<Third Embodiment>
In the present embodiment, when the content received by the digital receiver 30 or the content being played back by the recording / playback unit 24 is displayed on the liquid crystal display unit 62 on the liquid crystal television 10, a signal from the external device 11 is detected. The processing at this time will be described with reference to the flowchart of FIG. FIG. 7 shows a display pattern of the 3D state display unit 70. Here, it shall follow the pattern 1a.

  In addition, regarding the display mode of the 3D state display unit 70, the processing (S10 to S38) at the time of content reproduction of the digital reception unit 30 or the recording / reproduction unit 24 is the same, and therefore, mainly different points, that is, the external device 11 The processing (S24a, S24b, S28a, S28b, S34a, S34b, S38a, S38b) when detecting the signal from will be described.

  When the liquid crystal display unit 62 displays the 3D signal on the 3D screen (S22) and the 3D state display unit 70 is lit and displayed in color 1 (S24), the state display setting unit 56 receives the 3D signal from the external device 11 to 3D. A detection process of whether or not a signal is input is performed (S24a).

  When the 3D signal is not input (N in S24a), that is, in the case of the 2D signal, the state display setting unit 56 continues without changing the display state of the 3D state display unit 70. When a 3D signal is input (Y of S24a), the state display setting unit 56 changes the display state of the 3D state display unit 70 to alternate lighting of color 1 and color 5 (S24b).

  Next, when the liquid crystal display unit 62 compulsorily displays the 3D signal on the 2D screen (S26) and the 3D state display unit 70 is blinking with color 1 (S28), the state display setting unit 56 outputs the 3D signal externally. A detection process is performed to determine whether or not a 3D signal is input from the device 11 (S28a).

  When the 3D signal is not input (N in S28a), the state display setting unit 56 continues without changing the display state of the 3D state display unit 70. When the 3D signal is input (Y in S28a), the state display setting unit 56 changes the display state of the 3D state display unit 70 to alternate lighting of color 1 (blink) and color 5 (S28b).

  Subsequently, when the liquid crystal display unit 62 displays the 2D signal on the 2D screen (S32) and the 3D state display unit 70 is displayed in color 2 (S34), the state display setting unit 56 displays the 3D signal external device 11. To detect whether or not a 3D signal is input (S34a).

  When the 3D signal is not input (N in S34a), the state display setting unit 56 continues without changing the display state of the 3D state display unit 70. When the 3D signal is input (Y in S34a), the state display setting unit 56 changes the display state of the 3D state display unit 70 to alternate lighting of color 2 and color 5 (S34b).

  In addition, when the liquid crystal display unit 62 forcibly displays the 2D signal on the 3D screen (S36) and the 3D state display unit 70 is blinkingly displayed with color 1 (S38), the state display setting unit 56 displays the 3D signal external device. A detection process is performed to determine whether a 3D signal is input from 11 (S38a).

  When the 3D signal is not input (N in S38a), the state display setting unit 56 continues without changing the display state of the 3D state display unit 70. When the 3D signal is input (Y in S38a), the state display setting unit 56 changes the display state of the 3D state display unit 70 to alternate lighting of color 1 (blink) and color 5 (S38b).

  According to the present embodiment, when a 3D signal is received from a peripheral device (such as a BD recorder, satellite broadcast receiver, mobile terminal, or media tablet) via an external input path (HDMI, WiFi, etc.), the external device 11 at that time 3D signal is input from the external device 11 to the liquid crystal television 10 by the predetermined display control of the 3D state display unit 70, and 3D viewing can be enjoyed by switching to the external input. This can be clearly noticed.

  During standby, for example, when the remote controller 86 or the like is operated, the state display setting unit 56 may scan for the presence / absence of a 3D signal in the external input path from the external device 11. Further, the state display setting unit 56 may poll and scan for the presence or absence of a 3D signal in the external input path at a predetermined cycle.

<Fourth Embodiment>
In the present embodiment, a case will be described in which a 3D broadcast is received on a channel other than the channel being viewed. For example, when the 3D state display unit 70 is displayed according to the pattern shown in FIG. 4 according to the original signal, the state display setting unit 56 refers to the EPG or the acquired TS and performs 3D on another channel. If it is determined that the content can be viewed, the display mode of the 3D state display unit 70 is changed. For example, the color 6 is displayed. By performing such processing, it can be clearly noticed that another channel is performing 3D broadcasting, and that if a channel selection operation is performed, it is possible to enjoy 3D broadcasting of another channel.

<Fifth Embodiment>
In the present embodiment, a case where 3D broadcasting can be received before a predetermined time will be described. FIG. 8 is a diagram illustrating a display state in the case of informing a 3D broadcast scheduled to have two 3D state display units 70 according to the present embodiment. For example, when the 3D status display unit 70 is displayed according to the pattern shown in FIG. 4 according to the original signal, the status display setting unit 56 refers to the EPG and the 3D broadcast program is updated within a predetermined time. If it is determined that it exists, the display mode of the 3D state display unit 70 is changed so that it can be understood. As shown in FIG. 1, when the 3D state display unit 70 is composed of one set, the display color is changed or blinked. Here, a case where the 3D state display unit 70 includes two sets (70a and 70b) will be described. Display control according to the current signal and display mode is performed on the left 3D state display unit 70a.

  In the right 3D state display unit 70b, for example, when there is a 3D broadcast program for a scheduled program within two hours, predetermined display control is performed. Here, when it is determined that there is a 3D broadcast 30 minutes later by referring to the EPG, a relatively small display is made as shown in FIG. On the other hand, when 3D broadcasting is scheduled most recently (after 5 minutes), it is displayed in the same size as the left 3D state display unit 70a. That is, the state display setting unit 56 changes the display size of the 3D state display unit 70b according to the length up to the scheduled time.

  When the channel scheduled for 3D broadcasting is the same as the current channel, it is displayed in the same color, and when it is scheduled for a different channel, it is displayed in a different color.

<Sixth Embodiment>
FIG. 9 is a diagram showing the relationship between the EPG selection state and the display pattern of the 3D state display unit according to the present embodiment. FIG. 10 is a flowchart showing an interlocked display process between the EPG selection state and the 3D state display unit 70.

  The display of the 3D state display unit 70 is controlled based on whether or not the program in the frame selected by the cursor in the EPG as described above includes 3D program information. This process will be described with reference to the flowchart of FIG. First, when a user moves the cursor on the EPG and selects a program, it is determined whether or not the program in the selected frame is 3D content (S210). At the time of determination, the state display setting unit 56 determines whether the corresponding program is 3D content or 2D content from the EPG / OSD processing unit 80. When the program of the selected frame is 3D content (Y in S210), the 3D state display unit 70 is displayed in, for example, color 1 (blue) (S212). When the program of the selected frame is 2D content (N in S210), the 3D state display unit 70 is displayed in, for example, color 2 (white) (S212).

  For example, in FIG. 9A, the program selected by the cursor is the broadcast station “XYZ1”, the time 19:00:00 to 20:00, the program “special feature 123”, and 2D content. In this case, the 3D state display unit 70 is lit with color 2 (white). In FIG. 9B, the program selected by the cursor is the broadcast station “XYZ1”, the time 20: 00 to 21:00, the program “drama ABC”, and the 3D content. In this case, the 3D state display unit 70 is lit with color 1 (blue). Further, in FIG. 9C, the program selected by the cursor is the broadcast station “WXY1”, the time is 20:00 to 21:00, the program “stock news”, and 2D content. In that case, the 3D state display unit 70 is lit in color 2 (white).

  Note that the control items are not limited to the display mode described above, and may be lighting / different color lighting, blinking / other color blinking, blinking / different color blinking, extinguishing, and the like. By performing such processing, it is possible to determine whether or not the program to be reserved is 3D content even when viewing reservation is made using EPG.

<Seventh Embodiment>
FIG. 11 is a flowchart showing the display processing of the 3D state display unit 70 accompanying the warning processing by the cumulative 3D viewing according to the present embodiment, when the 3D or pseudo 3D content is continuously viewed for a predetermined time from the start of viewing. The display setting unit 56 displays a warning that the display control of the 3D state display unit 70 exceeds 3D viewing.

  Specifically, when viewing of the 3D or pseudo 3D content is started (S310), the state display setting unit 56 starts a process of accumulating the viewing time of the 3D or pseudo 3D content (S312). Note that, for example, an interruption of about several minutes is determined as continuous viewing and the cumulative processing is not initialized. Subsequently, display control of the 3D state display unit 70 corresponding to viewing of 3D or pseudo 3D content is performed (S314). Then, the state display setting unit 56 checks whether the accumulated viewing time is within a predetermined time (S316), and if within the predetermined time (Y in S316), continues the display control of the 3D state display unit 70 as usual. (S314). For example, the 3D state display unit 70 is controlled to be in a lighting state of color 1 (blue). On the other hand, if the predetermined time is exceeded (N in S316), the state display setting unit 56 performs display control of the 3D state display unit 70 in a warning state (S318). For example, the 3D state display unit 70 is controlled to blink in color 1 (blue).

  By performing such processing, it is possible to determine whether the viewing time of the 3D content is appropriate without affecting the screen display itself. In addition, when this process is applied to the above-described fifth embodiment and a viewing reservation is made with the EPG, the 3D state display unit 70 is displayed in a warning state when the estimated accumulated 3D viewing time exceeds a predetermined time. You may do it. Further, in that case, it may be set so that 3D or pseudo 3D content display cannot be performed.

<Eighth Embodiment>
FIG. 12 is a flowchart showing processing when reflecting the 3D surround setting information on the 3D state display unit 70 according to the present embodiment.

  As the 3D surround setting, “Standard” as a general-purpose setting recommended by the manufacturer, “Movie theater” as a movie theater setting, “Concert hall” as a concert hall setting, and “Off” without 3D surround. There are four settings. This setting is made, for example, when the user selects a setting hierarchy such as “setting” → “audio adjustment” → “3D surround” from the home menu up to a predetermined selection screen.

  When viewing of 3D or pseudo 3D content is started (S410), the state display setting unit 56 checks whether 3D surround setting is made, that is, whether "off" is set (S412). ). In the case of “off” setting (Y in S412), the state display setting unit 56 controls the 3D state display unit 70 to be turned off (S414). Of the two characters “3D”, only one character, for example, only the number “3” may be a display control target related to the 3D surround setting.

  When the 3D surround setting is made (N in S412), the state display setting unit 56 checks whether or not “movie theater” is selected as the 3D surround setting (S416). When “movie theater” is selected (Y in S416), the state display setting unit 56 controls the 3D state display unit 70 to a display mode corresponding to “movie theater”, for example, color 1 (blue) ( S418).

  When “movie theater” is not selected (N in S416), the state display setting unit 56 checks whether “concert hall” is selected as the 3D surround setting (S420). When “concert hall” is selected (Y in S420), the state display setting unit 56 controls the 3D state display unit 70 to a display mode corresponding to “concert hall”, for example, color 2 (white) ( S422). If “concert hall” is not selected (N in S420), the state display setting unit 56 controls the 3D state display unit 70 to a display mode corresponding to “standard”, for example, color 3 (red). (S424).

  By performing such processing, it is possible to grasp whether or not the audio setting is 3D surround without checking on the screen, in other words, without disturbing the display of the content.

<Ninth Embodiment>
FIG. 13 is a flowchart illustrating processing when reflecting the 3D brightness setting information on the 3D state display unit 70 according to the present embodiment.

  There are three 3D brightness settings: “Standard”, a general-purpose setting recommended by the manufacturer, “High”, a setting with a higher brightness than the standard, and “Low”, a setting with a lower brightness than the standard. . This setting is performed, for example, when the user selects a setting hierarchy such as “setting” → “video adjustment” → “3D brightness up” from a home menu up to a predetermined selection screen. The 3D brightness setting is a screen brightness setting when displaying 3D or pseudo 3D content.

  When viewing of 3D or pseudo 3D content is started (S510), the state display setting unit 56 checks whether or not the 3D brightness setting is “weak” (S512). In the case of “weak” setting (Y in S512), the state display setting unit 56 controls the display mode corresponding to “weak” in the 3D brightness setting, for example, color 1 (blue) (S514).

  When the setting is not “weak” (N in S512), the state display setting unit 56 checks whether “strong” is selected as the 3D brightness setting (S516). When “strong” is selected (Y in S516), the state display setting unit 56 controls the 3D state display unit 70 to a display mode corresponding to “strong”, for example, color 2 (white) (S518). . If “strong” is not selected (N in S420), the state display setting unit 56 controls the 3D state display unit 70 to a display mode corresponding to “standard”, for example, color 3 (red) ( S520).

  By performing such processing, it is possible to grasp how the 3D brightness setting is set without checking on the screen, in other words, without disturbing the display of the content.
