2The C bus.
As shown in Figure 1, the present invention is at the remote controller of television set and control panel, and " adding/release " key is set, and one adds flag bit for the channel data item of program channel, and program channel is realized encrypting; Two reset for the flag bit of the channel data item of program channel, to the program channel deciphering, and in the display screen upper right corner with the tapered end symbol as " adding/release " state of @ ◎ ▲ symbols such as ■ ★ ◇ demonstration (OSD) program channel.
Set " adding/release " key:
The one, " adding/release " state of prompting program channel;
The 2nd, program channel is carried out " adding/release " operation;
The 3rd, with all program channels that lock " complete solution lock ".
Sequencing and the time length pressed with " adding/release " key realize respectively:
Press for the first time, and the time less than 2 seconds, carry out prompt facility;
Press for the first time, and the time greater than 2 seconds, then carry out the complete solution latching operation;
Press for the second time, then current program channel is carried out " adding/release " operation: promptly originally do not lock, (set program channel data flag bit and show in the screen upper right corner symbol that locks) now locks; Originally locked, now with regard to release (program channel data that resets flag bit also removes the symbol that locks in the screen upper right corner).
After program channel is locked, use " P+/P-" key to change platform, with a scope internal conversion at the program channel that locked, promptly receive only the program channel (channel program that the flag bit of its channel data item is set) that has locked and watch for the user, all are former searches the program channel that do not lock in the channel of platform storage and does not show without exception.To make the user full out find own favorite program channel like this with minimum operating procedure.Come compared with existing operation, not only convenient but also quick.
When only having one to lock program, by " P+/P-" key, will be tuned to a next one/last program channel, that is to say, this moment with " P+/P-" key channel selection meeting in conversion between three platforms-lock program platform and next/last, rather than the demonstration program platform that locks only.Because if at that rate, the user can take for " P+/P-" key and lose efficacy by coming by going to lose variation.
After program channel was locked, it locked and is not subjected to the influence of program channel row number change between sign and the program channel.Be if that a certain program channel was locked in a platform number position originally, after it is changed be put into the position No. ten again, its sign that locks can be come the position No. ten together in company with this program channel, rather than breaking away from program channel, to be trapped in an original position separately motionless.Because the flag bit that program channel locks is as one in the channel data, in operation with regard to together access of channel data.
Using the numerical key channel selection, judgement symbol position not can access the user at any time and want any one program channel of watching.
The present invention gives the analysis and judgement ability to television set, imports, automatic operation is set according to the difference of button, finds corresponding program channel with prestissimo.
Describe principle of the present invention and process in detail below in conjunction with accompanying drawing: start, microcontroller takes out the channel data item of selected program channel when last time shutting down from the memory of self, then, wherein tuning data is passed through I
2The C bus is delivered to tuner, watches selected channel program when last time shutting down.Wait for the control command of sending from remote controller or control panel then.If without any control command, then watch current program, this is the present invention's program process of television set before.

2 judgements also show adding/released state (promptly having/do not have the symbol of locking) of current program, and give the user with prompting, carry out information interchange, are convenient to next step operation fashion of user and shoot the arrow at the target.Detailed process: microcontroller accesses the data item of the current channel of storing its inside, and to judge its flag bit, if lock, the data of the symbol that then will lock access and pass through I
2The C bus is delivered to decoder, send picture tube to show in the screen upper right corner through decoding.
3 microcontrollers change and go to the monitor command input port after finishing aforesaid operations.Detailed process: after aforementioned " adding/release " key that is pressed discharges, just finish delay procedure immediately, the time (being time of delay) of pressing release from " adding/release " key is kept at the timer of microcontroller.
Whether the duration (being time of delay) that 4 judgement " adding/release " keys are pressed is less than 2 seconds.
5 if the button duration more than or equal to 2 seconds.Operation: the reset flag bit that locks of all programs that lock of microcontroller, to all programs that lock " complete solution lock ", be convenient to the user and reselect.
6 if the button duration less than 2 seconds.Detailed process: microcontroller monitor command input port sees if there is " adding/release " key entry for the second time.
7 if there is " adding/release " key entry for the second time.Detailed process: then look into the flag bit of channel program data earlier, judge whether to lock, how decision is operated according to original " adding/release " state then: locked originally, and now with regard to release, i.e. the microcontroller channel identification position that resets; Originally do not lock, lock now, be i.e. microcontroller set channel identification position, " adding/release " state behind storage and the display operation.
So far the adding an of channel/unlocking operation has just been finished.If do not change platform, just watch current program; If want a plurality of programs are added/release, change and repeat aforesaid operations after the platform and just can add release one by one.
If 8 change platform (after " adding/release " key presses for the first time, having or not to press for the second time to forward this step to).Detailed process: microcontroller monitors its order input port, seeks the scope of program channel according to the platform mode of changing (keying in number or " P+/P-" incremented/decremented immediately) decision that the user adopts.
9 usefulness numerical key modes are changed platform.Detailed process: key in and count the number of words (being actually channel), by the operation of the program process before the present invention, no matter whether lock, all program channels that is stored in the television set can both come out according to user's wish program request.Whether new program channel locks and is selected by the user.
The mode of 10 usefulness incremented/decremented is changed platform.Detailed process: key in " P+/P-" key, microcontroller will be judged in the existing program earlier to have or not the program channel that locks after receiving " P+/P-" key, decide next step how to operate according to judged result.
11 through judging, if do not lock program channel, detailed process: change original incremented/decremented program.Whether new program channel locks and is selected by the user.
12 through judging, if lock program channel.Detailed process: microcontroller is judged the quantity of the program channel that locks.
13 if only have a program channel, will be on lock program and its program that locks incremented/decremented in the next program three scope of a program and the program that locks.Here next/last one is the program that do not lock, at this special circumstances of the program channel that locks only and set, in order to avoid the user produces misunderstandings when operating.New whether locking of program channel selected by the user.
14 if there is the plural program channel that locks.Seek platform with " P+/P-" key, incite somebody to action only incremented/decremented in the channel program scope that locked, the realization selectivity is watched.
