Below some concepts are made an explanation, conveniently more clearly understand technical scheme of the present invention.The retentivity time of eye of human eye is between 50 milliseconds to 200 milliseconds, so film when making on this basis, with one seconds 24 frame mode play, the time slot between frame and frame is probably 41.6 milliseconds, animation also can be on this basis when making, and is arranged on 16 frames a second.therefore, the present invention is based on this characteristics and proposed to solve the technical scheme of the problem that exists in correlation technique, be switched to program B when broadcast program A, program recording B after switching, if can again switch back program A within the scheduled time, although or will can not affect so spectators watches the picture effect very little data (for example two frames) of loss of program A but picture is affected little, because human eye also persists the television image before switching, but in fact channel has been carried out switching and recorded program B within this time period, be generally 24 frame per seconds for the frame number that the video pictures broadcast is set, so the present invention can be more than or equal to 24 hertz with the set of frequency of switching channels, namely switching cycle is general for being less than or equal to 41.6 milliseconds, this numerical value is within the retentivity time of eye of human eye, under the prerequisite that guarantees image quality, can be also less than 24 hertz with the set of frequency of switching channels.
Fig. 4 shows the flow chart that is used for according to an embodiment of the invention the program processing method of Mobile Multimedia Broadcasting.
As shown in Figure 4,, in step 402, the interested channel A of user is set, channel B.Channel A is set to broadcast message class and adds programm name, the reproduction time of playing, and channel B is set to record class and adds recorded program title, reproduction time.The user wishes when watching the program of channel A, to the recording program of channel B.
In step 404, read the channel information that the user arranges, this information is included in the details of the channel that step 402 arranges such as channel designation (be each channel corresponding No. ID), affiliated classification (broadcast message class or record class), programm name, reproduction time etc.
In step 406, start CMMB chip (CMMB:China Mobile Multimedia Broadcasting, China Mobile multimedia broadcasting) (being programme signal processing module 206), this CMMB chip is used for receiving and resolving broadcast television signal.
, in step 408, judge the current mobile multimedia broadcast signal (being programme signal) that whether has.If there is no broadcast television signal directly withdraw from, if broadcast television signal is arranged enter step 410.
, in step 410, start two worker threads: play thread (being used for displaying video) and record thread (being used for recorded video).Can realize same time point by variable, when a thread is in running order, another thread is in idle condition.
In step 412, control the CMMB chip with two channels of preset frequency switching, this preset frequency can be for 24 hertz or greater than 24 hertz.In the time of the channel switching, realize the switching of two worker thread operating states and idle condition, that is to say, when being switched to the program of channel A, the broadcast thread is in running order, records thread and is in idle condition, when being switched to the program of channel B, play thread and be in idle condition, record thread in running order.This frequency values can design according to the picture frame number of program video to increase or reduce, and also according to the power of the programme signal of program channel A, adjusts switching frequency, preferentially guarantees the program quality of program channel A.
In step 414, when play thread in working order under, receive and resolve the media signal of current channel A, the program of broadcasting channel A maybe ought record thread in working order under, receive and resolve the media signal of current channel B, the program of channel B is saved in this locality.
Can only receive the program of a channel due to this CMMB chip synchronization, therefore the duplex that adopts is made thread, carry out switching channels recording TV program B can allow the user at TV reception A the time within rational unit interval, because the mankind's vision has the effect of persisting, so can not aware the interruption effect of video pictures.in other words, if the user is watching mobile TV program A, after the picture of the first frame is play, be switched to immediately mobile TV program B and carry out recording of TV programme B, the time of recording can be within 41.6 milliseconds, because the next frame picture of TV programme A will be at 41.6 milliseconds (if video playback be play according to the mode of per second 24 frames, the time slot that calculates between frame and frame is probably 41.6 milliseconds) play afterwards, need so at this moment channel to be switched again telegram in reply and look program A, the vision of human eye also rests on the picture of the first frame within these 41.6 milliseconds, so just can not affect spectators' TV reception is that picture effect is smooth, also can record simultaneously another in progress program, should be appreciated that at this, play as according to calculating by per second 24 frames take video standard for these 41.6 milliseconds, the numerical value of these per second 24 frames is critical values, if video is play by per second 25 frames or by per second 30 frames, preset frequency in the present invention also can be replaced by 25 hertz or 30 hertz so, by that analogy, like this, preset frequency in technical scheme of the present invention can be for more than or equal to 24 hertz, except arranging the frequency of channel switching according to the video playback frame number, under the prerequisite that can guarantee image quality, also can reduce the frequency of channel switching, for example in the situation that with per second 24 frames, carry out displaying video, can be take two frames as the channel switching interval, the time interval of switching is 83.2 milliseconds so.
Although the CMMB chip in embodiment shown in Figure 4 (being programme signal processing module 206) can only be processed the signal of a program, but should be appreciated that, this CMMB chip can be processed the signal of a plurality of programs simultaneously, can record or play for each program, in other words, simultaneously a plurality of programs are processed, and do not needed to adopt the mode of switching channels to reach purpose of the present invention.in addition, adopt the mode that starts two worker threads in embodiment shown in Figure 4, the program channel that each worker thread is corresponding different, when one of them worker thread work, the another one worker thread is in idle condition, that is to say when processing program A, do not have corresponding program B to process, when processing program B, program A is not processed, can certainly only start a worker thread, process for program A at certain time point, process for program B at ensuing time point, carry out the switching of channel and do not need to start two worker threads in same worker thread, such mode equally also can reach purpose of the present invention.
By technical scheme of the present invention, adopt duplex to make thread, control the CMMB chip with the different channel of preset frequency switching, realization is recorded, the synchronous execution of playing function.When meeting user's TV reception A, recording TV program B, saved user time, improved user's experience.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
