Embodiment
Be example with concrete execution mode below, the present invention is described in further detail.
As shown in Figure 1, be that the structural representation block diagram of the control multimedia decoding processing section of multimedia mobile terminal according to an embodiment of the invention is described.This multimedia mobile terminal comprises multi-medium data receiving element 110, multi-medium data decoding unit 120, the multi-medium data output unit 130 that is used to handle the multi-medium data that receives, and the communication unit 140 and the multimedia decoding control unit 150 that are used to initiate or receive audio call, described multimedia decoding control unit 150, be used for detecting that described communication unit 140 is being initiated and when receiving audio call, controlling described multi-medium data decoding unit 120 and between multiple decoding schema, switch.
Wherein, described multi-medium data decoding unit 120 disposes multiple decoding schema, can comprise:
1, normal decoder pattern, when described communication unit 140 was not initiated or received audio call, described multi-medium data decoding unit 120 worked in the normal decoder pattern, and the multi-medium data that receives is carried out video and audio decoder;
2, the pattern of only video data being decoded, when detecting that described communication unit 140 is being initiated or when receiving audio call, switch to described pattern of only video data being decoded by the described multi-medium data decoding unit 120 of described multimedia decoding control unit 150 controls, the multi-medium data that receives is carried out video decode;
3, the pattern of only the partial video data being decoded, when detecting that described communication unit 140 is being initiated or when receiving audio call, switch to described pattern of only the partial video data being decoded by the described multi-medium data decoding unit 120 of described multimedia decoding control unit 150 controls, the multi-medium data that receives is carried out the partial video decoding;
4, the pattern of only video data of low resolution being decoded, when detecting that described communication unit 140 is being initiated or when receiving audio call, switch to described pattern of only video data of low resolution being decoded by the described multi-medium data decoding unit 120 of described multimedia decoding control unit 150 controls, the low-resolution video data in the multi-medium data that receives are decoded.
In addition, according to concrete applied environment, can also dispose other decoding schemas, for example directly close video decode, or only voice data is decoded, perhaps adopt the similar tupe of other reduction terminal resource consumption, and the method for operation that the method that the partial data of vision signal is decoded is reduced the decoding operand comprising the resolution of reduction vision signal, the frame per second of reduction video etc.The detailed process of above-mentioned various decoding schemas and algorithm all have clear and definite realization in the prior art, do not do concrete narration here, embodiment of the present invention, mainly be to detect that described communication unit 140 is being initiated and when receiving audio call, controlling described multi-medium data decoding unit 120 and between multiple decoding schema, switch.
Referring to shown in Figure 1, embodiment of the present invention will describe multimedia mobile terminal in detail and watch structure and operation with voice communication.
At first, for described multimedia mobile terminal multiple decoding schema is disposed in the decoding of multi-medium data;
Secondly, behind multi-medium data receiving element 110 receiving multimedia broadcast data or the stream medium data, multimedia packed datas such as output audio and video.These Voice ﹠ Video packed datas must carry out multimedia decoding at multi-medium data decoding unit 120, just can offer in the multi-medium data output unit 130 to display the play.
Wherein, when not having audio call, 120 pairs of multi-medium datas of multi-medium data decoding unit carry out normal decode operation.When communication unit 140 produces audio call, the voice call request that multimedia decoding control unit 150 receives from communication unit 140, and control multi-medium data decoding unit 120 changes decoding schemas, and multi-medium data is according to the output of decoding of new decoding schema.140 of communication units are handled the corresponding communication function.
At embodiment of the present invention, the control mode that changes decoding schema here is that the decoding of part is also just carried out in the decoding of multimedia decoding control unit 150 control multi-medium data decoding units 120 stop tone audio data to video data.
At last, be implemented in when carrying out audio call during the multimedia, effectively utilize limited terminal resource and handle video playback, or video playback and voice call service parallel processing are provided.
Another embodiment can stop the reception of video data among the embodiment of the present invention under the control of multimedia decoding control unit 150 for multi-medium data receiving element 110.
Also have an embodiment can under the control of multimedia decoding control unit 150, stop the broadcast of video data for multimedia output unit 130 among the embodiment of the present invention.
As shown in Figure 2, be according among the embodiment of the present invention, during watching multimedia service, be used for the flow chart of the method for conduct voice calls.
Among the embodiment of the present invention, multimedia mobile terminal produces voice call request 220 in constantly reception, play multimedia program series of steps receiving multimedia data 200, play multimedia 210.Wherein when multimedia mobile terminal receives audio call/or user when selecting communication function to initiate audio call, produce voice call request, in step 220, when closing audio call if the user selects to continue to watch multimedia programming, then the multimedia mobile terminal repeating step 200,210;
If embodiment user of the present invention selects to carry out audio call, multimedia mobile terminal is carried out and is switched to decoding schema step 230 and connect audio call 240.Switching encoding/decoding pattern 230 these steps are important, carry out the multi-medium data decoding according to associative mode in the new decoding schema and can reduce the multimedia mobile terminal resource consumption, under the limited situation of multimedia mobile terminal performance, be convenient to multimedia mobile terminal and can handle multimedia and audio call simultaneously, switching encoding/decoding pattern 230 can be selected to stop audio decoder, reduce the resolution or the frame per second of video, that is to say that video decode just decodes to the partial data of former video.When carrying out voice communication, multimedia mobile terminal continues to carry out receiving multimedia data 250 and decodes and play multimedia 260 by new decoding schema.
If operate in that audio call does not finish in the step 270, repeating step 250,260 among the embodiment of the present invention; When voice communication finishes, return to the normal decoder pattern and watch multimedia 280.
According to embodiment of the present invention, when if audio call takes place in multimedia mobile terminal during multimedia service is watched in reception, can under the situation of not closing multimedia service, carry out voice communication simultaneously, effectively utilize limited multimedia mobile terminal resource and handle video playback, video playback and voice call service parallel processing method are provided; Can also work as when audio call takes place, close the broadcast of the audio signal in the multimedia service simply, keep the broadcast of vision signal, treat to recover voice playing when audio call finishes, can provide good business experience to the user like this; And a kind of method of multimedia decoding pattern control, particularly control the method that decoder is only decoded to the video data of part.
Above-mentioned embodiment describes the present invention with preferred embodiment, should not be regarded as limitation of the scope of the invention.Equally, according to the description of technical scheme of the present invention and preferred embodiment thereof, can make various possible being equal to and change or replacement, and all these changes or replacement all should belong to the protection range of claim of the present invention.
