Abstract

A video/audio data processing module is provided. By directly transmitting audio streams of different channels designated by multiple users to mobile devices respectively held by the users, instead of being restricted to a limitation that a digital TV being capable of playing a monophonic audio, the users are enabled to listen to audios of respective desired programs.

Claims

1. A video/audio data processing method, applied to a digital TV, the digital TV configured to simultaneously play a plurality of videos on a screen, the method comprising:

receiving a plurality of selection instructions, each of the selection instructions being sent out by a device and for selecting one of a plurality of channels;

decoding source data to obtain video data and audio data corresponding to the selected channels respectively;

playing the video data corresponding to the selected channels on the screen simultaneously; and

transmitting the audio data corresponding to the selected channels to the devices respectively.

2. The method according to claim 1, further comprising:

detecting the devices within a detection range of the digital TV; and

establishing a connection between the digital TV and the devices.

3. The method according to claim 1, wherein the videos are played in a plurality of areas on the screen respectively, the method further comprising:

setting a configuration of the areas according to the selection instructions.

4. The method according to claim 1, wherein the digital TV is one of the devices.

5. A video/audio data processing module, applied to a digital TV, the digital TV configured to simultaneously play a plurality of videos on a screen, the module comprising:

a control module, configured to generate a first control signal and a second control signal according to a plurality of selection instructions, each of the selection instructions being sent out by a device and for selecting one of a plurality of channels;

a decoder, configured to decode source data to obtain video data and audio data corresponding to the selected channels respectively, and to output the video data corresponding to the selected channels for playback on the screen simultaneously; and

a data transmission module, configured to transmit the audio data corresponding to the selected channels to the devices respectively.

6. The module according to claim 5, further comprising:

a detection module, configured to detect the devices within a detection range of the digital TV and to establish a connection between the control module and the devices.

7. The module according to claim 5, further comprising:

a detection module, configured to detect the devices within a detection range of the digital TV and to establish a connection between the data transmission module and the devices.

8. The module according to claim 5, wherein the videos are played in a plurality of areas on the screen respectively, the control module sets a configuration of the areas according to the selection instructions.

9. The method according to claim 5, wherein the digital TV is one of the devices.
