Embodiment
For making purpose of the present invention, technical scheme clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
The present invention is a kind of EPG program guiding method, sets in advance the EPG trigger condition, and this method mainly may further comprise the steps:
Read the EPG trigger condition, judge whether current state satisfies the triggering state in the EPG trigger condition, if, then start secondary picture, determine secondary picture channel according to the secondary picture play content information in this EPG trigger condition, and determined channel is presented on the described secondary picture, otherwise, return and carry out this step.
In order to open secondary picture automatically, and the program that the user need watch play on secondary picture, the present invention is according to user's needs, set in advance the EPG trigger condition that comprises triggering state and secondary picture play content information, triggering state representation wherein starts the time of secondary picture, program, film or channel etc. that the information representation of secondary picture play content need be watched.For the ease of the EPG trigger condition is set, triggering state and secondary picture play content information can be represented by trigger message and Timing Advance.For example: trigger message is 1 channel/19:00, when Timing Advance is 5 minutes, and then triggering this moment state is that 18:55, secondary picture play content information are 1 channel.In addition, in EPG trigger condition of the present invention, also comprise and the relevant Word message of secondary picture play content information, so that the user can understand the content of playing in the secondary picture fast.Among the present invention, the trigger condition formation that above-mentioned EPG trigger condition is constituted is kept among the MEM.
Referring to Fig. 3, the EPG program guiding method that the present invention is based on many TUNER system may further comprise the steps:
In this step, many TUNER system shown in Figure 1 brings into operation through after powering on.
Open flag bit by the display frame in the PIP module herein, judge whether display frame opens.Under the situation that display frame is opened, MCU reads television set or computer shown channel of key frame before shutdown last time at this many TUNER system place from MEM, and by a TUNER in the system, the signal of this channel is incorporated in the PIP mixing module, on key frame, plays.
In addition,, therefore also the EPG programme to be read out from MEM, so that subsequent step uses because the EPG programme also is stored among the MEM.
The same with TV newspaper commonly used, can only comprise the TV programme in a period of time in the EPG programme.Therefore, can recognize program in current and following a period of time in order to make the user, the EPG programme will carry out regular update.EPG programme after each the renewal all has the effective time of self, then in this step, by judging that the current time is whether in the effective time of EPG programme, determine whether this EPG programme is effective, if promptly the current time judges that then this EPG programme is effective in the effective time of EPG programme; Otherwise, judge that this EPG is invalid.
The formation of EPG trigger condition is read in step 306～308. from MEM, and judges whether to exist the EPG trigger condition, if then read first condition in the formation of current EPG trigger condition; Otherwise, finish this EPG program guiding flow process.
In order to make many TUNER of the present invention system can determine to start automatically the time of secondary picture, this place reads out the formation of the predefined EPG trigger condition of user from MEM; And after in the trigger condition formation of having determined to read, having trigger condition, from this trigger condition formation, obtain first trigger condition, so as in the subsequent step according to this trigger condition, determine the automatic unlatching of secondary picture.
Step 309～310. judge whether the current time satisfy current trigger condition, if, then send the EPG triggering signal, start the secondary picture of the program of playing current trigger condition correspondence; Otherwise, return execution in step 309.
With the EPG trigger condition formation shown in the table 1 is example, and each trigger condition all includes projects such as trigger message, Timing Advance and Word message.Wherein trigger message occurs with forms such as the title of the required play content of user or channel/times, and wherein the title of the required play content of user can be programm name or film title.
| Trigger message | Timing Advance | Word message |
| Same first song | 3 minutes | Same first song is come into Beijing |
| 1 channel/19:00 | 5 minutes | News hookup |
| Yongzheng imperial court | 2 minutes | Yongzheng imperial court (3) |
Table 1
This place judges that the method whether current time satisfy current trigger condition has two kinds:
When trigger message occurs with the form of programm name or film title, at first be called index with this programm name or film name, retrieval EPG programme, find the broadcasting channel and the time started of this program or film, again deducted the Timing Advance in the current trigger condition time started that obtains, and then definite current EPG trigger condition time corresponding, the i.e. start-up time of secondary picture; Then, judge again whether the current time arrive this pair picture start-up time, if, judge that then the current time satisfies current trigger condition, otherwise, judge that the current time do not satisfy current trigger condition.For example: suppose that the current time is 13:50, for first EPG trigger condition in the table 1, this place at first finds the time started of same first song program in the EPG programme be 14:00, and the Timing Advance in this trigger condition is 3 minutes, and then be 13:57 the start-up time of secondary picture; Then, because current time no show 13:57 still, then return and judge whether the current time arrives secondary picture start-up time.
When trigger message occurs with the form of channel/time, only need the time in the trigger message is deducted Timing Advance, can obtain current EPG trigger condition time corresponding, i.e. the start-up time of secondary picture; And then judge whether the current time arrive this pair picture start-up time, if, judge that then the current time satisfies current trigger condition, otherwise, judge that the current time do not satisfy current trigger condition.For example: suppose that the current time is 18:55, for second EPG trigger condition in the table 1, this place is 5 minutes according to 19:00 in the trigger message and Timing Advance, and the opening time of determining secondary picture is 18:55; Then, because the current time is identical with the secondary picture opening time, judge that then the current time satisfies current trigger condition.
Satisfy in the current time under the situation of current trigger condition, MCU sends the EPG triggering signal to the PIP module, wherein carry content, start the secondary picture of the program of playing this trigger condition correspondence automatically such as current trigger conditions such as secondary picture channel and Word messages.With first trigger condition in the table 1 is example, and automatically open secondary picture this moment on display screen, and what play in the secondary picture is the channel at same first song program place.
Step 311～312. turn to the next trigger condition in the formation of EPG trigger condition, and judge whether current EPG trigger condition is empty, if then finish this EPG program guiding flow process; Otherwise, return execution in step 309.
Because through after the operation of above-mentioned steps, first trigger condition is finished by many TUNER of the present invention system, so turns to the next trigger condition in the formation of EPG trigger condition in this step.
And,, show that then all EPG conditions that user have been provided with all are finished, and therefore, finish EPG program guiding flow process of the present invention if current EPG trigger condition is empty.
So far, EPG program guiding flow process of the present invention is finished.
In addition, as shown in Figure 4, the method that starts the secondary picture of the program of playing current trigger condition correspondence in the above-mentioned steps 310 may further comprise the steps:
Step 401～402. judge whether to receive the EPG triggering signal, if then obtain the details of EPG triggering signal; Otherwise, return execution in step 401.
After the PIP mixing module receives the EPG triggering signal, from this triggering signal, obtain such as secondary picture channel, be shown in the details such as Word message on the secondary picture, so that open corresponding secondary picture in the subsequent step, and on secondary picture, show the Word message that gets access to.
Step 403～404. judge whether there is secondary picture in the current display screen, if then execution in step 405; Otherwise, open secondary picture window, continue execution in step 405 again.
This place is according to showing the flag bit of secondary picture state judges whether there is secondary picture in the display screen, when this flag bit is when showing the numerical value of secondary picture unlatching, to judge in the display screen to have secondary picture; When this flag bit is when showing the numerical value that secondary picture do not open, judge in the display screen not have secondary picture.For example: when this flag bit is 1, show that secondary picture has been present on the display screen; When this flag bit is 0, show that secondary picture is not present on the display screen.
The channel picture of step 405～406. in the details that secondary screen displayed gets access to, and the Word message in these details is shown on the secondary picture.
In two steps at this place, at first, the PIP mixing module is presented at the channel picture of accessed EPG signal details correspondence on the secondary picture, for example: the channel in the details is 1 channel, then plays the TV programme of 1 channel in secondary picture this moment; Then, the Word message in the details is shown on the secondary picture, for example: the Word message that comprises in the details is news hookup again, can occur the text prompt of news hookup on the then secondary picture.
Because the time of implementation of two steps in this place is very short, therefore from user's angle, when secondary picture started, just playing had the pairing channel picture of current trigger condition, and shows related words information.
So far, the program of finishing the automatic unlatching of secondary picture and in secondary picture, playing user's setting automatically.After this, continue to return step 311 in the execution graph 3.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
