Description

A method for controlling TV program timing change

technical field

The invention relates to a control method for regularly changing channels of television programs.

Background technique

Existing TV sets basically all have the function of quick look back now, as long as press the return key on the remote controller, can return to that channel that watched before this from current channel. You can switch back and forth between the two channels, which provides a lot of convenience for users who want to watch the programs of the two channels. For example, you can watch TV dramas on Channel 1, and switch to the football on Channel 5 during commercials or breaks, or you can switch between the two channels. The fast review function of the TV is realized by controlling the tuner through the MCU of the TV. When pressing the number keys of the remote control or the channel plus and minus keys to change the TV channel, the relevant data of the previous channel frequency has been assigned to a variable of the MCU. When the return key on the remote control is pressed, the program of channel change is started, and the MCU takes out the relevant data of the previous channel frequency, channel number, etc. from the variable to control the data output of the tuner to realize the channel return. However, only one variable is used for assignment in the MCU, so there is only one channel frequency related data. When the user changes the TV channel many times, he cannot simply press the return button on the remote control to return to a previous channel. . Simultaneously, existing TV also does not have the timing function of watching back. These two points have brought a lot of inconvenience to TV viewers. For example, TV programs often have a lot of advertisements, and people often switch to other channels to browse other programs during the advertisement time. But often when you want to switch back to this channel, you either miss some feature time, or you can't find the channel for a while. For example, you switch to Channel 5 to watch football during the advertising time of TV dramas on Channel 1, but when you are fascinated by watching football, you often forget that the advertising time of TV dramas is over and you can watch TV dramas. This is likely to miss the wonderful part of the TV series.

The Chinese Invention Patent Publication published on February 22, 2006 the patent application "a method for intelligent management of television sets" with the application number CN200510021259.5. The patent application mentions "scheduled start-up and timing switch. Viewers can pre-set different times according to personal preferences to watch different channels when browsing the TV program list. When the preset time is reached, the TV will automatically turn on and switch channels." But this patent application has neither provided the concrete method that realizes by preset time, TV automatically boots and turns the channel, more does not provide the method that TV program can return to the originally set channel in the time set by the user.

Contents of the invention

The technical problem to be solved by the present invention is to provide a method for controlling TV program timing change. According to this method, the TV program can return to the originally set channel within the time set by the user.

In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is a method for controlling regular channel change of TV programs, comprising the following steps:

101. When the TV is turned on, enter the program of timing channel change control setting;

102. Set and save channel changing time;

103. Under the channel to be played regularly, confirm the regular channel change and save the frequency or channel number of the current channel;

104. Monitor whether the set channel change time is reached, once the set channel change time is reached, the channel change program is invoked, and the TV plays the channel with the saved frequency or channel number.

In the above-mentioned control method for regularly changing channels of TV programs, the time for changing channels may be a time period or a specific moment.

After implementing this method, no matter how the user changes the channel, how many times the channel is changed, and which channel the user changes to, as soon as the set time arrives, the TV will automatically return to the channel set by the user to allow the user to continue watching the program. The method can facilitate the user to accurately avoid the advertising time, use the advertising time to watch wonderful programs of other stations, and can also handle other affairs during the waiting time without missing the scheduled program.

Description of drawings

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Fig. 1 is a flow chart of the present invention.

Fig. 2 is the secondary menu of time setting in Embodiment 2 of the present invention.

Detailed ways

The flow of the method can be described in conjunction with FIG. 1 . Firstly, a setting menu key, a time setting key and a channel-changing control key must be defined in the program. After the TV is turned on, the key scanning processing program starts to monitor whether the user presses the setting menu key. The user who wants to realize the function of changing the channel regularly should first press the setting menu key to start the setting program of the function of changing the channel regularly, and call out the setting menu. Press the time setting key to set the time for regular channel change, and save the set channel change time when exiting the setting program. After setting the time, you can press the switch control button at any time to enter the timing program. Once the button scanning processing program detects that the user presses the channel-changing control key, it starts timing and stores related data such as the channel-changing time and the current channel frequency when the user presses the channel-changing control key. The software background loop control program continuously monitors whether the set channel changing time is reached. Once the set channel changing time is reached, it will call out the relevant data of the channel frequency stored in the memory, and call the channel changing program. The TV play has been saved. frequency channel.

Example 1:

Add a new key on the TV remote control, and define this new key in the program as a setting menu key, and at the same time define the volume plus and minus keys on the TV remote control as the time setting key in the submenu of setting the time , and define the confirmation key on the TV remote control as a channel-changing control key in the submenu of setting time. When the TV is turned on, the user presses the setting menu key to issue a corresponding infrared command, and the infrared receiver on the TV receives the infrared modulation signal of this command and demodulates the signal into a pulse position modulated command pulse and sends it to the central processing unit (MCU), after the central processing unit (MCU) decodes this command, call out the corresponding timing channel change control setting menu, and wait for the TV user to input the timing time. At this time, the TV user can press the volume up key or the volume down key on the remote controller to set the time for timing, and the time range is 0 to 180 minutes. After setting, the TV user presses the confirmation key on the remote controller of the TV to exit the timing channel change control setting menu. The control program saves the channel-changing time input by the user and the relevant data of the current channel frequency in the memory, and the timing program inside the central processing unit (MCU) starts working at the same time. No matter what channel the TV user switches the TV set to after this, as long as the timing time arrives, the control program will automatically switch the TV set to that channel set by the user to allow the user to continue watching the scheduled program. For example, when a TV user watches a certain TV series on the central station, the TV program will have 10 minutes of commercials inserted. If the TV user does not want to watch the advertisement, he presses the setting menu key to bring up the timing channel change control setting menu. Set the timing time to 10 minutes by pressing the volume plus and minus keys on the remote control, and press the confirmation key to exit the timing channel change control setting menu. Thereafter, the user uses the channel addition and subtraction keys to transfer to the third central station to watch theatrical programs via the second central station. When 10 minutes are up, the TV automatically switches back to the central one, the TV advertisement has been broadcast, and the TV user just continues to watch the feature film of the TV series. In this way, the user avoids the advertisement accurately, and uses the advertisement time to watch the wonderful programs of other stations without missing the feature film time.

Example 2:

When the user is ready to set the timed channel change, he presses the setting menu key of the remote controller at the front desk to start the setting program, and the first-level setting menu appears on the TV screen. At this time, press the volume plus and minus keys to move and select the time submenu. After selecting the time submenu, use the program minus key to enter the secondary menu of time setting, as shown in Figure 2. Then use the program plus and minus keys to select up and down to the commercial channel change option, and use the volume plus and minus keys to increase or decrease the commercial channel change time. After the time is set, you can press the setting menu key to exit the menu. At this time, the system will save the advertising channel change time in the memory, as long as you do not enter the time menu again to change the time, the time setting is always valid.

After the advertising channel changing time is set, when the user needs it, press the advertising channel changing control button on the remote control, then the screen will display the characters whose advertising channel changing time has been set, and the system will store the set advertising channel changing time. The station number or frequency of the station. The background system of the software starts timing, and constantly compares the counted time with the advertisement channel change time set by the user. Before the advertisement channel change time arrives, no matter how the user changes the channel or which channel, as long as the advertisement changes As soon as the time is up, the system will call the channel-changing program and the stored channel number to automatically switch to the channel that is set for advertising.

The channel-changing time set in the above embodiments is a time period, which is more convenient for TV users who want to temporarily avoid a section of advertisement, because the time for inserting advertisements will not be very long. However, it is more convenient to input the absolute time of a specific moment for TV viewers who are waiting for a wonderful program at a certain moment of a certain TV channel. Since the general TV does not come with a real-time clock system, the time of the machine is also set by the user when the TV is turned on. If the TV turns off the AC power, the set time will be cleared, but in the standby state , the local time can be saved and run all the time.

The setting of the absolute time depends on the correct setting of the local time. After the user has set the local time, he can input the start time of a certain TV series, and then press the control button of the channel change time at the time of the channel number. At this time The program will memorize the channel number and the set channel changing time, and then start a cycle in the background, and compare it with the current time continuously. When the current time is equal to the set time, it will call the stored channel number to perform Change the channel and complete the function of timing channel change.
