Abstract

A method for transmitting service data of a handset TV is disclosed in the present invention, wherein, an audio part and a video part of a handset TV program are split into an audio sub-service and a video sub-service respectively, and when transmitting the service data of the handset TV program, a transmitting terminal splits the service data into audio sub-service data and video sub-service data; the transmitting terminal respectively transmits the audio sub-service data and the video sub-service data on different transmission resources, and transmits association relationship information of the audio sub-service and the video sub-service to a terminal. In the present invention, a transceiver operates in a DRX mode in a long time to effectively save the handset power energy; in addition, in implementation, the present invention only needs to update the software in the existing system, which causes very small changes to the system and is low in cost, thus the overall performance of the handset TV is effectively improved.

Claims

1. A method for transmitting service data of a handset TV, comprising:

splitting an audio part and a video part of a handset TV program into an audio sub-service and a video sub-service respectively, and when transmitting the service data of the handset TV program, a transmitting terminal splitting the service data into audio sub-service data and video sub-service data;

the transmitting terminal respectively transmitting the audio sub-service data and the video sub-service data on different transmission resources, and transmitting association relationship information of the audio sub-service and the video sub-service to a terminal.

2. The method according to claim 1, wherein,

when the terminal receives the service data of the program, if a user selects to only listen to an audio or only watch a video, then the terminal only receives the audio sub-service data or only receives the video sub-service data according to the received association relationship information;

if the user selects to play the audio and the video simultaneously, the terminal receives both the audio sub-service data and the video sub-service data according to the received association relationship information.

3. The method according to claim 2, wherein

the transmitting terminal transmits transmission resource information of the audio sub-service and the video sub-service to the terminal before respectively transmitting the audio sub-service data and the video sub-service data, and the terminal receives the audio sub-service data and/or the video sub-service data according to the transmission resource information.

4. The method according to claim 3, wherein

the association relationship information employs a separate announcement or a combined announcement, wherein the separate announcement means that the audio sub-service and the video sub-service are respectively configured with guide information, an audio attribution and the video sub-service associated with the audio sub-service are indicated in the guide information of the audio sub-service, while a video attribution and the audio sub-service associated with the video sub-service are indicated in the guide information of the video sub-service;

the combined announcement means that the program is configured with combined guide information, wherein whether the audio part and the video part of the program are split into the audio sub-service and the video sub-service is indicated in the combined guide information, if yes, the combined guide information further comprises service IDs for the audio sub-service and the video sub-service to identify the association relationship.

5. The method according to claim 4, wherein

when the user selects to play the audio and the video simultaneously, during the process of playing the program, if the user performs a silencing operation, the terminal only receives the video sub-service data according to the transmission resource information of the video sub-service data and plays the video sub-service data;

if the user selects to shut down the video, the terminal only receives the audio sub-service data according to the transmission resource information of the audio sub-service data and plays the audio sub-service data.

6. The method according to claim 4, wherein

in a China Mobile Multimedia Broadcasting (CMMB) system, the transmission resources are transmission time slots of the audio sub-service data and the video sub-service data, and the process of respectively transmitting the audio sub-service data and the video sub-service data is:

the transmitting terminal packages the audio sub-service data and the video sub-service data into different multiplex frames, and the multiplex frame packaged with the audio sub-service data and the multiplex frame packaged with the video sub-service data are transmitted respectively in different transmission time slots.

7. The method according to claim 6, wherein

the transmission resource information comprises transmission time slot information of the audio sub-service data and transmission time slot information of the video sub-service data, the transmitting terminal transmits the transmission resource information to the terminal through a continuous-service multiplex configuration table (CMCT);

when the user selects to only listen to the audio or only watch the video, the terminal searches the transmission time slot information of the audio sub-service data or the video sub-service data in the CMCT according to the service ID of the audio sub-service or the video sub-service contained in the association relationship information, and only receives the audio sub-service data or only receives the video sub-service data according to the transmission time slot information;

when the user selects to play the audio and the video simultaneously, the terminal searches the transmission time slot information of the audio sub-service data and the video sub-service data in the CMCT according to the service IDs of the audio sub-service and the video sub-service contained in the association relationship information, and receives the audio sub-service data and the video sub-service data respectively according to the transmission time slot information.

8. The method according to claim 7, wherein

the association relationship information is contained in an electronic service guide (ESG), and an audio sub-service ID field is added in the ESG to indicate the service ID of the audio sub-service;

a video sub-service ID field is added to indicate the service ID of the video sub-service; and

a service split indication field is added in the ESG to indicate whether the audio part and the video part of the program are split into the audio sub-service and the video sub-service.

9. A method for receiving service data of a handset TV, comprising:

when a terminal receives the service data of a handset TV program, if a user selects to only listen to an audio or only watch a video, then the terminal only receiving respectively transmitted audio sub-service data or video sub-service data of the program according to received association relationship information;

if the user selects to play the audio and the video simultaneously, the terminal receiving both the audio sub-service data and the video sub-service data of the program according to the received association relationship information.

10. The method according to claim 9, wherein

in a China Mobile Multimedia Broadcasting (CMMB) system, when the user selects to only listen to the audio or only watch the video, the terminal searches transmission time slot information of the audio sub-service data or the video sub-service data in a received continuous-service multiplex configuration table (CMCT) according to a service ID of an audio sub-service or a video sub-service contained in the association relationship information, and only receives the audio sub-service data or only receives the video sub-service data according to the transmission time slot information;

when the user selects to play the audio and the video simultaneously, the terminal searches transmission time slot information of the audio sub-service data and the video sub-service data in the CMCT according to service IDs of the audio sub-service and the video sub-service contained in the association relationship information, and respectively receives the audio sub-service data and the video sub-service data according to the transmission time slot information.
