Decoding Terminal Data Distribution in Audio Video Matrix Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing network audio/video matrix systems face challenges in efficiently distributing data to a large number of decoding terminals without requiring high-capacity encoding terminals or additional distribution servers, leading to increased complexity and costs.
Innovation Solution
The proposed data transmission method involves a decoding terminal in a network audio/video matrix system that manages data distribution by determining its occupied capacity, sending a secondary distribution device table to secondary decoding terminals when capacity is maxed, and disconnecting from them to handle data requests dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data distribution is performed through a special distribution server, then data distribution capability is improved, but system complexity and construction costs increase
Solution Approach 1:
The patent extracts the data distribution function from a dedicated distribution server and relocates it to ordinary decoding terminals. Each decoding terminal that receives audio/video data can forward it to other decoding terminals, eliminating the need for a special distribution server and reducing system complexity while maintaining distribution capability
Solution Approach 2:
The patent makes ordinary decoding terminals multi-functional by enabling them to perform both data reception and data distribution functions. Decoding terminals are no longer just passive receivers but can also act as active distributors, allowing any terminal to forward audio/video data to other terminals in the network
2Productivity
If data distribution is performed through a special distribution server, then data distribution capability is improved, but construction and usage costs increase
Solution Approach 1:
The patent removes the requirement for a special distribution server by extracting the distribution function and embedding it in ordinary decoding terminals. This eliminates the need for additional hardware construction and reduces ongoing usage costs while preserving the ability to distribute data to multiple terminals
Solution Approach 2:
The patent replaces the expensive, dedicated distribution server with ordinary decoding terminals that already exist in the system. These terminals are cheaper, more readily available, and sufficient for the distribution task, eliminating the need to invest in specialized expensive equipment
3Productivity
If the encoding terminal has high data processing capabilities and high throughput network interface, then data distribution capability is improved, but device complexity and costs increase
Solution Approach 1:
The patent segments the data distribution task across multiple decoding terminals rather than concentrating it in a single encoding terminal. Each decoding terminal handles only a portion of the distribution workload, reducing the complexity and hardware requirements for individual devices while achieving overall high distribution capability through collaborative effort

AI summary
A data transmission method is applied to a decoding end of a network audio and video matrix system, and the decoding end is in communication connection with an encoding end and several secondary decoding ends. The data transmission method comprises: acquiring request data signaling from a secondary decoding end, wherein the request data signaling comprises a distribution data signaling receiving address of the secondary decoding end; determining whether a currently occupied distribution capability value reaches a maximum distribution capability value; and if yes, sending a secondary distribution device table to the secondary decoding end, such that the secondary decoding end sends the request data signaling to other secondary decoding ends in the secondary distribution device table, and after the sending of the secondary distribution device table is completed, disconnecting a network connection with the secondary decoding end.
