Context-Aware Media Signal Prioritization for Low-Latency Remote Live
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote live event systems experience significant delays in media signal transmission due to unequal consideration of media signal importance and audience relationships, leading to discomfort in the remote audience experience.
Innovation Solution
A transmission apparatus and method that acquires media signals, selects them based on context information such as importance and audience interaction, and transmits them accordingly to reduce delays and maintain experience quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all media signals are transmitted with equal priority to eliminate delay, then transmission speed is improved, but data quality and experience comfort deteriorate due to loss of important elements
Solution Approach 1:
The patent applies local quality by differentiating transmission priorities based on the specific characteristics of each media signal. Important signals such as audience reactions (cheers, fanchants) and critical video frames are transmitted with higher priority and greater redundancy, while less important signals use standard transmission parameters. This resolves the contradiction by ensuring that speed improvements do not compromise the quality of critical data elements.
Solution Approach 2:
The patent dynamically changes transmission parameters including priority levels, redundancy ratios, and resource allocation based on the importance classification of each media signal. By adjusting these parameters according to signal criticality, the system achieves both fast transmission for important signals and high quality preservation, resolving the speed-quality contradiction.
2Reliability
If context information processing is added to select media signals, then data quality is improved through prioritization, but device complexity increases
Solution Approach 1:
The patent segments the media signal processing into distinct functional modules: acquisition unit, context information calculation unit, selection unit, and transmission unit. Each module performs a specific function, making the overall complex system manageable and maintainable. The segmentation allows context information processing to be added without overwhelming the system architecture.
Solution Approach 2:
The system performs self-service by automatically calculating context information and making transmission decisions without requiring external intervention. The selection unit autonomously determines which media signals to transmit based on calculated context information, reducing the need for complex external control mechanisms and simplifying system operation.
3Reliability
If context information calculation is performed for all media signals, then transmission quality is improved, but processing time increases
Solution Approach 1:
The patent applies partial action by calculating context information for only those media signals that require prioritized transmission rather than all signals. The selection unit identifies and processes only the critical subset of media signals needing context analysis, reducing overall processing time while maintaining transmission quality for important elements.
Solution Approach 2:
The system skips detailed context information calculation for low-priority media signals that do not require sophisticated processing. By rushing through or bypassing extensive analysis for non-critical signals and focusing computational resources on important signals, the system reduces total processing time while maintaining high transmission quality where it matters most.
