Audio Stream Integration Using Common Index Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D audio transmission technologies require strict ordering of audio frames to facilitate decoding, increasing processing load when integrating multiple audio streams, as configuration information is not consistently linked with encoded data within the frames.
Innovation Solution
Incorporating common index information within both the 'Frame' and 'Config' packets of audio streams, allowing for flexible ordering and integration without decomposing the composition of each stream, thereby reducing processing load during stream integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If configuration information is not linked with encoded data within audio frames, then decoding processing can be performed, but the order of audio frames must be restricted and processing load increases during stream integration
Solution Approach 1:
The patent introduces index information as an intermediary element that links configuration information with encoded data within audio frames. This index information acts as a mediator that enables flexible ordering of frames while maintaining proper decoding relationships, thereby reducing processing complexity during stream integration without sacrificing operational ease
2Reliability
If strict ordering of audio frames is enforced, then decoding processing can be performed correctly, but processing load increases when integrating multiple audio streams
Solution Approach 1:
The index information serves as a mediator that preserves decoding correctness by maintaining the relationship between configuration information and encoded data, while simultaneously enabling flexible frame ordering that improves stream integration efficiency. This intermediary allows receivers to integrate multiple audio streams without being constrained by strict ordering requirements
3Productivity
If index information is inserted in both Frame and Config packets, then stream integration processing load is reduced, but packet structure becomes more complex
Solution Approach 1:
The index information structure is designed to serve multiple functions simultaneously: it provides frame identification, establishes configuration data relationships, and enables flexible ordering during stream integration. By making the packet structure multi-functional through the index information field, the patent achieves improved stream integration efficiency without proportionally increasing structural complexity

AI summary
It is attempted to reduce the processing load of a receiver at the time of integrating plural audio streams.A predetermined number of audio streams are generated, and a container of a predetermined format including these predetermined number of audio streams is transmitted. The audio streams are constituted by an audio frame including a first packet that includes encoded data as payload information and a second packet that includes configuration information representing a configuration of the payload information of this first packet as payload information. Common index information is inserted in payloads of related first packet and second packet.
