Audio Packet Relay Prioritization for Low-Latency Ensemble Networking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to effectively support ensembles of performers working from different locations, leading to sound delays and dropouts due to inadequate prioritization of audio packets in network transmission.
Innovation Solution
A communication relaying method and apparatus that prioritizes audio packets over data packets, utilizing a communication controller to manage queuing and transmission, and adjusts codec and flow control to minimize delays and dropouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio packets are transmitted without priority over data packets in a network, then network resource utilization is improved, but sound delays and dropouts occur
Solution Approach 1:
The patent changes the transmission parameter by assigning priority levels to different packet types. Audio packets are assigned high priority while data packets are assigned low priority, fundamentally altering the transmission behavior from equal treatment to differentiated priority-based transmission.
Solution Approach 2:
The patent implements dynamic packet scheduling where the transmission queue is continuously managed based on packet type. The communication relaying apparatus dynamically adjusts transmission order, placing audio packets ahead of data packets in the transmission queue to ensure timely audio delivery.
2Reliability
If audio packets are prioritized over data packets in transmission, then sound delays and dropouts are reduced, but network complexity increases
Solution Approach 1:
The patent segments the transmission queue into different priority levels. Audio packets are placed in a high-priority queue while data packets are placed in a low-priority queue, allowing independent management and transmission of each packet type according to its requirements.
Solution Approach 2:
The communication relaying apparatus acts as an intermediary between the network and the audio/data sources. It introduces a priority-based scheduling mechanism that mediates packet transmission, automatically managing the complexity of priority handling without requiring changes to the endpoint devices.
