In actual applications, during playing television program at mobile terminal, the user needs to pay close attention to video screen all the time.Use occasion according to user's use habit and portable terminal is different, and in some cases, the user may only need listen to the sound of TV programme, and does not need to see video.And existing portable terminal is when handling television broadcasting signal, be that the Voice ﹠ Video signal is all handled, thereby when the user only need listen to the sound of TV programme, can consume certain power consumption of portable terminal to Video signal processing, can not reach purpose of power saving, shortened the service time of portable terminal, also brought bad experience to the user.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of terminal playing method and portable terminal of mobile TV, satisfying the demand that the user only listens to TV programme sound, and saves power consumption, prolongs the service time of portable terminal.
For achieving the above object, technical scheme of the present invention is achieved in that
The invention provides a kind of terminal playing method of mobile TV, this method comprises:
Enter no video pattern, and initiate to close the Video processing task order;
According to the described Video processing task order of closing, described Video processing task is closed, and normally carry out the Audio Processing task.
The described Video processing task is closed specifically comprises:
Close LCD LCD;
Empty the video code flow in the screen buffer;
Close the video decode module;
Close the audio video synchronization module.
Described the Video processing task is closed after, this method also comprises: from described no video mode switch to normal play mode, and with described Video processing task recovery.
Described the Video processing task recovery is specifically comprised:
Open described LCD;
Keep the video code flow in the described screen buffer;
Open described video decode module;
Open described audio video synchronization module.
The present invention also provides a kind of portable terminal, comprising:
No video pattern enters the unit, is used to enter no video pattern, and initiates to close the Video processing task order;
The task closing unit is used for described Video processing task being closed, and normally carrying out the Audio Processing task according to the described Video processing task order of closing.
Described portable terminal also comprises: the task recovery unit, be used for from described no video mode switch to normal play mode, and with described Video processing task recovery.
The terminal playing method of mobile TV provided by the present invention and portable terminal when the user only need listen to the sound of TV programme, enter no video pattern, Processing tasks Close All that will be relevant with video; Under no video pattern, portable terminal only plays sound, display video not, thus saved the Processing tasks relevant with video, reduced power consumption of mobile terminals, saved the electric weight of portable terminal, improved the service time of portable terminal.

Embodiment
The technical solution of the present invention is further elaborated below in conjunction with the drawings and specific embodiments.
The terminal playing method of a kind of mobile TV provided by the present invention as shown in Figure 2, mainly may further comprise the steps:
Step 201, portable terminal enter no video pattern, and initiate to close the Video processing task order.
At first, a kind of new mode of operation need be set on portable terminal, promptly not have the video pattern, and be arranged under the no video pattern, any Processing tasks relevant with video in the portable terminal is all no longer carried out.Portable terminal can select to enter no video pattern by the mode of menu operation, and initiates to close the Video processing task order; Certainly, also can enter no video pattern by the state backlight of LCD automatically, when backlight the closing of LCD, terminal is identified as no video pattern automatically, and initiates to close the Video processing task order.
Step 202, portable terminal is closed the Video processing task, and is normally carried out the Audio Processing task according to closing the Video processing task order.
As can be seen, Processing tasks relevant with video in the portable terminal comprises from existing television broadcasting signal processing procedure shown in Figure 1: will deposit screen buffer in to the video flowing that code stream carries out obtaining behind the demultiplexing; Video flowing to buffering is decoded; Decoded video and audio signal is carried out Synchronous Processing; Vision signal after the Synchronous Processing is play by LCD.
Accordingly, portable terminal is according to closing the Video processing task order, and the operation that the Video processing task is closed specifically comprises:
A, close the backlight of LCD.
B, the video code flow in the screen buffer is emptied.
C, close the video decode module.It is pointed out that if the operation of video decode is realized by hardware module, then described hardware module is directly closed; If the operation of video decode is realized by software module, then directly skip the executable operations of described software module.
D, close the audio video synchronization module, no longer carry out the operation of video and audio sync.
Under the situation that the Video processing task is closed, the Audio Processing task in the portable terminal is normally carried out, and is unaffected.In addition, after step 202, if desired portable terminal is switched to normal play mode again, then can operate below the corresponding execution:
A, open the backlight of LCD.
B, keep the video code flow in the screen buffer, the video code flow in the screen buffer is no longer carried out emptying operation.
C, open the video decode module.It is pointed out that if the operation of video decode is realized by hardware module, then described hardware module is directly opened; If the operation of video decode is realized by software module, then trigger described software module and carry out the corresponding video decoding operation.
D, open the audio video synchronization module, carry out the Synchronous Processing operation of audio signal and vision signal.
Terminal playing method according to mobile TV shown in Figure 2, the television broadcasting signal processing procedure of correspondence then as shown in Figure 3 among the present invention, portable terminal is by the code stream of TV RF tuner and television demodulator received tv broadcast signal, comprising ESG information and program source data etc.; The MPEG2 TS that obtains is carried out demultiplexing, parse audio stream, video flowing, program guide and authentication information, described audio stream that parses and video flowing deposit corresponding audio buffering area and screen buffer respectively in; Video flowing in the screen buffer is emptied, and then have to the audio stream of program guide, authentication information and buffering; Audio stream in the audio buffer is decoded; Decoded audio signal is outputed to loud speaker to be play.
For realizing the terminal playing method of above-mentioned mobile TV, the present invention also provides a kind of portable terminal, and as shown in Figure 4, this portable terminal comprises: no video pattern enters unit 10, task closing unit 20 and task recovery unit 30.Wherein, no video pattern enters unit 10, is used to enter no video pattern, and initiates to close the Video processing task order.Task closing unit 20, entering unit 10 with no video pattern links to each other, be used for according to closing the Video processing task order, the Processing tasks of carrying out in the portable terminal relevant with video closed, specifically comprise: close LCD, empty video code flow in the screen buffer, close the video decode module, close operations such as audio video synchronization module.Task recovery unit 30, link to each other with task closing unit 20, be used for from no video mode switch to normal play mode, and Processing tasks that will be relevant with video recovers, and specifically comprises: open LCD, keep video code flow in the screen buffer, open the video decode module and open operation such as audio video synchronization module.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
