Handset TV Service Data Splitting for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handset TV terminals consume unnecessary power when users select to only play either the audio or video part of a program, as they still receive the entire data packet containing both parts, even though the unused part is not required.
Innovation Solution
The method splits a handset TV program into audio and video sub-services, allowing the terminal to transmit and receive only the selected sub-service data, along with association and transmission resource information, enabling efficient power management by operating in a discontinuous reception mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal receives the entire data packet containing both audio and video parts, then the user can access all program content, but the terminal consumes unnecessary power when only audio or video is needed
Solution Approach 1:
The patent segments the service data into separate audio sub-service data and video sub-service data, allowing the terminal to receive only the needed portion (audio or video) rather than the entire data packet, thus reducing power consumption while maintaining content accessibility
Solution Approach 2:
The patent extracts the audio and video components from the unified service data packet and transmits them separately, enabling the terminal to take out and process only the required sub-service data, eliminating unnecessary power consumption for receiving unwanted content
2Use of energy by moving object
If the terminal receives only the selected audio or video part, then power consumption is reduced, but the association relationship between audio and video may be lost
Solution Approach 1:
The patent introduces association relationship information as an intermediary element that carries the linkage between audio and video sub-services, allowing the terminal to maintain the association relationship even when receiving only one sub-service at a time
Solution Approach 2:
The patent performs preliminary action by transmitting association relationship information before the actual audio or video data, enabling the terminal to understand the relationship between components in advance and manage playback accordingly while saving power

AI summary
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.
