Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network environments face challenges in managing video data processing, including redundant processing that leads to suboptimal performance and inefficient video quality monitoring due to the lack of effective communication channels and distributed processing capabilities.
Innovation Solution
A communication protocol is established to embed video processing characteristics and metrics directly into compressed bit streams, allowing for transparent and efficient video quality monitoring and distributed processing across network elements, using protocols like H.264 to support transport statistics and quality metrics without requiring explicit communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video processing is performed at multiple network elements, then video quality monitoring capability is improved, but redundant processing occurs causing network equipment to become overwhelmed and performance to degrade
Solution Approach 1:
The patent divides video processing tasks across multiple network elements (routers, switches, gateways) along the data stream path. Each network element performs specific processing functions and embeds processing information into the data stream, allowing distributed video quality monitoring without centralizing all processing at one point. This segmentation enables monitoring capability while distributing the processing load to prevent any single element from becoming overwhelmed.
Solution Approach 2:
The patent implements a feedback mechanism where network elements embed processing information (such as processing characteristics, quality metrics, and status data) directly into the data stream. Subsequent network elements can read this embedded information to understand what processing has already occurred and adjust their operations accordingly, reducing redundant processing while maintaining comprehensive video quality monitoring capability.
2Adaptability or versatility
If processing information is communicated through separate communication channels, then video processing coordination is improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent merges the video processing coordination function with the existing data stream transmission channel. Instead of creating separate communication channels for processing information, the system embeds processing characteristics, quality metrics, and control data directly into the video data stream itself. This approach enables comprehensive video processing coordination while utilizing the already-deployed network infrastructure without adding separate communication pathways.
Solution Approach 2:
The data stream serves multiple functions simultaneously: it carries the video content, embeds processing information for coordination between network elements, and provides quality monitoring data. This multi-functionality eliminates the need for dedicated communication channels for processing coordination, reducing device complexity while maintaining versatile video processing capabilities across the network.
