detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides a method for switching a television signal source. Referring to FIG. 1, a flow chart of a first embodiment of a method for switching a television signal source according to the present invention is shown.

In this embodiment, the method for switching the television signal source includes:

Step S10, when receiving the signal source switching instruction, running the first main process that closes the current signal source, and simultaneously running the first sub-process and the second sub-process that close the current signal source;

It should be noted that the method for switching the television signal source proposed by the present invention is applicable to various television sets, such as digital television, smart televisions with intelligent operating systems, and the like. Hereinafter, a smart television will be described as an example, but the present invention is not limited thereto.

The user can switch the signal source switching command based on the signal source switching control set by the remote control device of the television set or the signal source switching button set on the television set. For the television, when receiving the signal source switching instruction, the first main process is run, and the first main process includes various operations closely related to the current signal source. Specifically, the first main process, that is, the television, performs the following steps. :

Turn off the currently playing audio and video, stop the detection of the current source, and close the channel of the current source.

The process of turning off the current source is: turn off the currently playing audio and video, avoid the situation of the screen in the subsequent process, and stop the signal detection of the current source after the sound is turned off. When the general smart TV is working, it will Detecting the currently used signal source, for example, detecting whether the signal of the signal source is locked, the format of the signal, the change of the signal, etc., at this time, the detection of the signal is stopped, that is, the detection of the above contents is stopped, Failure to do so may result in an error in the signal service, for example, a signal change may cause an incorrect execution of the signal detection service. Regarding the stop detection, that is, the control and each service module stop performing their respective functions. After the detection of the current source has stopped, the channel of the current source is turned off.

While running the first main process, the second sub-process is run, and the second sub-process is to close some services related to the current signal source, such as some implementations take a long time, but will not affect the main process of the switching signal source. The service, specifically, runs the first secondary process, ie the TV performs the following steps:

Stop the hbbtv service of the current source and reset the output of the SCART interface.

Understandably, some sources may need to enable hbbtv (Hybrid Broadcast/Broadband) TV, a DVB-compatible content distribution platform) service, therefore, when the first sub-process is running, the hbbtv module is detected, and if the function of the hbbtv module is currently on, the service of the module is stopped, if the module It is itself off, so you don't need to do anything to keep it off. Similarly, for the reset of the SCART interface output, if there is a SCART interface output, reset it, otherwise no operation is required.

After stopping the detection of the current signal source, starting to run the second secondary process;

Run the second secondary process, the TV, to perform the following steps:

The various functions associated with the program play of the current source are stopped to complete the operation of the second secondary process.

For different signal sources, there may be unnecessary functions for the playback of the program, such as whether there is a subtitle service, whether it is 3D playback, etc., and the second sub-process mainly detects various functional modules related to the program play of the current signal source, if When a function module is turned on, its corresponding function is stopped. For example, when the current source is ATV (analog TV signal) or DTV (digital TV signal), the subtitle function will be stopped, for example, CC (Closed) Caption, American standard subtitles, etc., the teletext function is currently enabled, and the function is also stopped. Among them, teletext is a TV text broadcast, which is generally used in Europe; if 3D playback is enabled, the next source may not have 3D. Therefore, it is generally necessary to stop the 3D function.

Step S20, after the first main process is completed, running a second main process that turns on the target signal source to complete the switching of the television signal source, wherein when the channel of the current signal source is closed, determining the first main After the process is completed, after the state of the target signal source is saved, it is determined that the second main process is completed.

After the first main process is completed, that is, after the channel of the current source is turned off, the second main process can be started to start the target signal source. It can be understood that if the second sub-process is not completed at this time, the process can still be continued. run. Specifically, the first main process is run, that is, the television performs the steps of: detecting a signal of the target signal source; turning on a channel of the target signal source when detecting the signal of the target signal source, and saving the The current state of the target source.

The signal detection of the target signal source channel is started. When the signal of the target signal source changes, it is detected. When the signal is detected, the channel of the target signal source is turned on, and the state of the target signal source is saved. In general, the second secondary process has been run before the channel of the target source is turned on.

The above-mentioned first main process of turning off the current signal source and the second main process of turning on the target signal source constitute the main process of the television switching signal source in the present invention, that is, the main process is an indispensable process for switching the signal source, and The correlation between each service in the other sub-processes is not very large, and the function does not need to be coupled. Therefore, it can be executed concurrently with the main process; in addition, the time occupied by each service in the sub-process is often compared. Long, putting them in the secondary process execution can greatly reduce the total time taken by the source switch.

Therefore, before the TV is shipped or when the signal source switching process of the TV is set, the number of the main process and the secondary process, and the functions to be performed in the main process and the functions to be performed in each secondary process can be set in advance. .

Further, after the step S20 is completed, the method for switching the television signal source further includes the following steps:

After the second main process is completed, the third sub-process that turns on the target signal source is run to complete the setting of each function of the target signal source. Specifically, the third secondary process is executed, that is, the television performs the following steps: setting a sound configuration, a signal source re-display rate, and a proportional mode of the target signal source; and starting various functions related to the television program playing of the target signal source. And updating the channel configuration list; setting the lock of the target signal source, and determining whether the target signal source needs to enable the hbbtv service, and if necessary, turning on the hbbtv service of the target signal source.

When the channel of the target signal source is turned on, the test signal comes, and the sound setting is started. At this time, the sound and image are still turned off, the signal is locked, the sound and image are turned on; next, the signal source is redisplayed. Rate, different signal sources, the size of the displayed picture is different, like ATV analog signal, due to interference, the quality of the general edge is not very good, so the reproduction rate will be small, like DTV, HDMI (High Definition Multimedia Digital signals such as Interface, digital video/audio interface technology, anti-interference will be better, so the re-display rate will be larger, and the PC signal re-display rate requirement is 100%. The next step is to set the proportional mode. If the user adjusts 4:3 or 16:9, after switching the signal source, set the proportional mode according to the ratio set by the user. After the setting is completed, start OAD, CEC, CC, teletext, MTS and other services. The OAD is a function of upgrading the TV using the DTV channel, the CEC is the communication between the HDMI devices, the MTS is the Liyin detection service, and the Liyin is the near-instant down-converted audio multi-channel broadcast. Then update the channel list to prepare for channel playback. If the current source is locked, then if you need to start the hbbtv service, start the hbbtv service.

After the real switching source is turned on, as long as the current source state is saved, the switching signal source is completed, and the following sound settings, target signal source re-display rate, proportional mode, etc. can be started gradually, and these services are relatively expensive. At the time, the user can continue to execute in the background for the smooth operation of the user.

Referring to FIG. 2, a schematic diagram of a complete signal switching process when the television set is switched in the prior art, and FIG. 3 is a schematic flowchart of switching the signal source according to the method proposed by the present invention. The invention adopts a multi-process concurrent form to switch the signal source, which has no influence on the main process, but the time-consuming service is put into the secondary process execution, for example, the hbbtv service, the reset of the SCART interface output, etc., and the caption is stopped. The services such as CC and teletext are the same. They do not affect the main switching signal source, but they are time consuming. The execution time of these functions can be executed before the source channel is opened, so it can be executed concurrently. After writing code verification, the existing TV signal source switching takes 750ms, and with the method of the invention, the TV switching signal source only needs 200ms, which greatly improves the switching speed of the signal source and shortens the signal source switching occupation. time.

The method for switching the signal source proposed in this embodiment, when receiving the signal source switching instruction, runs the first main process to close the current signal source, and runs the second main process to turn on the target signal source, so that the price television is from the current signal source. Switching to the target signal source, and running the first sub-process and the second sub-process of the current source while running the first main process, so that when the source is switched, multiple processes can be synchronized That is, each function that needs to be executed in the process of switching the signal source is divided into multiple processes, and the operation of each sub-process does not affect the main process. Therefore, the synchronous operation can be concurrently performed, and the signal source is greatly improved. The switching speed shortens the time taken by the signal source switching, and solves the technical problem that the existing TV set signal switching speed is slow and takes a long time.

A second embodiment of the switching method of the television signal source of the present invention is proposed based on the first embodiment. In this embodiment, before the step of turning on the channel of the target signal source, the method for switching the television signal source further includes the steps of:

When detecting the signal of the target signal source, determining whether the second secondary process is running;

If the second secondary process is completed, performing a step of turning on a channel of the target signal source and saving a current state of the target signal source;

After the second secondary process is completed, the delay waits until the second secondary process is completed, and the step of turning on the channel of the target signal source and saving the current state of the target signal source is performed.

Since the functions of the settings are different when playing TV programs for different signal sources, the stop of services such as subtitles, CC, and teletext may not be executed before the target source channel is turned on. Therefore, when the target is detected. When the signal of the signal source is used, it is first determined whether the secondary process is running. If the operation is completed, the channel of the target signal source is turned on, and the current state of the target signal source is saved, otherwise the delay waits until the second pair The process execution is complete.

The invention also proposes a television set.

Referring to FIG. 4, it is a schematic diagram of functional modules of a first embodiment of a television set of the present invention.

In this embodiment, the television set includes:

The main process module 10 is configured to: when receiving the signal source switching instruction, run the first main process that closes the current signal source, and simultaneously run the first sub-process and the second sub-process that close the current signal source;

The secondary process module 20 is configured to: after the first primary process is completed, run a second main process that turns on the target signal source to complete the switching of the television signal source, where the channel of the current signal source is closed, The first main process is completed, and after the state of the target signal source is saved, it is determined that the second main process is completed.

It should be noted that the television set proposed by the present invention may be various types of television sets, such as digital televisions, smart televisions with intelligent operating systems, and the like. Hereinafter, a smart television will be described as an example, but the present invention is not limited thereto.

The user can switch the signal source switching command based on the signal source switching control set by the remote control device of the television set or the signal source switching button set on the television set. For the television, when receiving the signal source switching instruction, the main process module 10 runs the first main process, and the first main process includes various operations closely related to the current signal source. Specifically, the main process module 10 runs first. The main process, that is, on behalf of the television, performs the following operations: turning off the currently playing audio and video, stopping the detection of the current source, and turning off the channel of the current source.

The main process module 10 turns off the currently playing audio and video, avoids the situation that the screen will appear in the subsequent process, and stops the signal detection of the current signal source after the sound is turned off. When the general smart TV is working, it will be used currently. The signal source performs detection, for example, detecting whether the signal of the signal source is locked, the format of the signal, the change of the signal, etc., at this time, the detection of the signal is stopped, that is, the detection of the above contents is stopped, otherwise the signal is caused. An error occurs in the service. For example, a signal change can cause an erroneous execution of the signal detection service. Regarding the stop detection, that is, the control and each service module stop performing their respective functions. After the detection of the current source has stopped, the channel of the current source is turned off.

While the main process module 10 runs the first main process, the sub-process module 20 runs the second sub-process, and the second sub-process closes some services related to the current signal source, such as some implementations take a long time, but will not be The service that affects the main process of the signal source, in particular, the operation of the second sub-process by the sub-process module 20 includes: stopping the hbbtv service of the current source and resetting the output of the SCART interface.

It can be understood that some sources may need to enable the hbbtv service. Therefore, when the secondary process module 20 runs the first secondary process, the hbbtv module is detected. If the function of the hbbtv module is currently on, the module is stopped. Service, if the module itself is turned off, no action is required to keep it closed. Similarly, for the reset of the SCART interface output, if there is a SCART interface output, reset it, otherwise no operation is required.

After the main process module 10 stops the detection of the current signal source, the secondary process module 20 starts running the second secondary process;

The secondary process module 20 stops various functions associated with program play of the current source to complete the operation of the second secondary process.

For different signal sources, there may be unnecessary functions for the playback of the program, such as whether there is a subtitle service, whether it is 3D playback, etc., and the second sub-process mainly detects various functional modules related to the program play of the current signal source, if When the function module is in the on state, the corresponding function is stopped. For example, when the current signal source is ATV or DTV, the subtitle function will be stopped, for example, CC, etc., the teletext function is currently enabled, and the function is also stopped, wherein, teletext For TV text broadcasting, it is generally used in Europe; if 3D playback is turned on, because the next source does not necessarily have 3D, it is generally necessary to stop the 3D function.

After the main process module 10 completes the first main process, that is, after the channel of the current source is closed, the sub-process module 20 can start running the second main process to turn on the target signal source. It can be understood that if the second pair is at this time The process has not finished running and can still continue to run. Specifically, the main process module 10 completes detecting the signal of the target signal source; when detecting the signal of the target signal source, turns on the channel of the target signal source, and saves the current state of the target signal source.

The main process module 10 starts signal detection of the target signal source channel, and when the signal of the target signal source changes, it detects that when the signal is detected, the channel of the target signal source is turned on, and the state of the target signal source is saved. In general, the second secondary process has been run before the channel of the target source is turned on.

The above-mentioned first main process of turning off the current signal source and the second main process of turning on the target signal source constitute the main process of the television switching signal source in the present invention, that is, the main process is an indispensable process for switching the signal source, and The correlation between each service in the other sub-processes is not very large, and the function does not need to be coupled. Therefore, it can be executed concurrently with the main process; in addition, the time occupied by each service in the sub-process is often compared. Long, putting them in the secondary process execution can greatly reduce the total time taken by the source switch.

Therefore, before the TV is shipped or when the signal source switching process of the TV is set, the number of the main process and the secondary process, and the functions to be performed in the main process and the functions to be performed in each secondary process can be set in advance. .

After the second main process is completed, the secondary process module 20 runs a third secondary process that turns on the target signal source to complete setting of each function of the target signal source. Specifically, the secondary process module 20 sets a sound configuration, a signal source replay rate, and a proportional mode of the target signal source; starts various functions related to television program play of the target signal source, and updates a channel configuration list; Decoding the target signal source, and determining whether the target signal source needs to enable the hbbtv service, and if necessary, turning on the hbbtv service of the target signal source.

When the channel of the target signal source is turned on, the test signal comes, and the sound setting is started. At this time, the sound and image are still turned off, the signal is locked, the sound and image are turned on; next, the signal source is redisplayed. Rate, different signal sources, the size of the displayed picture is different, like ATV analog signal, due to interference, the quality of the general edge is not very good, so the reproduction rate will be small, such as DTV, HDMI and other figures Signal, anti-interference will be better, so the re-display rate will be larger, and the PC signal's re-display rate requirement is 100%. The next step is to set the proportional mode. If the user adjusts 4:3 or 16:9, after switching the signal source, set the proportional mode according to the ratio set by the user. After the setting is completed, start OAD, CEC, CC, teletext, MTS and other services. The OAD is a function of upgrading the TV using the DTV channel, the CEC is the communication between the HDMI devices, the MTS is the Liyin detection service, and the Liyin is the near-instant down-converted audio multi-channel broadcast. Then update the channel list to prepare for channel playback. If the current source is locked, then if you need to start the hbbtv service, start the hbbtv service.

After the real switching source is turned on, as long as the current source state is saved, the switching signal source is completed, and the following sound settings, target signal source re-display rate, proportional mode, etc. can be started gradually, and these services are relatively expensive. At the time, the user can continue to execute in the background for the smooth operation of the user.

Referring to FIG. 2, a schematic diagram of a complete signal switching process when the television set is switched in the prior art, and FIG. 3 is a schematic flowchart of switching the signal source according to the method proposed by the present invention. The invention adopts a multi-process concurrent form to switch the signal source, which has no influence on the main process, but the time-consuming service is put into the secondary process execution, for example, the hbbtv service, the reset of the SCART interface output, etc., and the caption is stopped. The services such as CC and teletext are the same. They do not affect the main switching signal source, but they are time consuming. The execution time of these functions can be executed before the source channel is opened, so it can be executed concurrently. After writing code verification, the existing TV signal source switching takes 750ms, and with the method of the invention, the TV switching signal source only needs 200ms, which greatly improves the switching speed of the signal source and shortens the signal source switching occupation. time.

In this embodiment, the television set, when receiving the signal source switching instruction, runs the first main process to close the current signal source, runs the second main process to turn on the target signal source, and switches the price television to the target signal from the current signal source. The source, and, while running the first main process, runs the first sub-process and the second sub-process that close the current source, so that when the source is switched, multiple processes can be synchronized, that is, the source The functions that need to be performed in the process of switching are divided into multiple processes, and the operation of each secondary process does not affect the main process. Therefore, synchronous operation can be performed concurrently, which greatly improves the switching speed of the signal source. The time taken by the signal source switching is shortened, and the technical problem that the signal source switching speed of the existing television set is slow and takes a long time is solved.

A second embodiment of the television set of the present invention is proposed based on the first embodiment.
