Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcast systems face challenges in efficiently optimizing video processing parameters for varying types of content, leading to unnecessary bandwidth consumption or degraded picture quality, as existing methods require detailed and sophisticated analysis for each individual program.
Innovation Solution
The system allows for real-time modification of video processing parameters by identifying event boundaries, classifying content types, and selecting preset video processor configurations, which are then encoded and delivered to subscribers, using protocols like SCTE-104 for in-band signaling and automation systems for dynamic optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If detailed and sophisticated analysis is performed for each individual program to optimize video processing parameters, then picture quality is improved, but system complexity and processing time increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting video processing parameters based on content classification. Instead of using fixed complex analysis for all content, the system changes parameters according to content type (e.g., sports, news, entertainment), achieving optimized picture quality while reducing the complexity of analysis required for each individual program.
Solution Approach 2:
The patent segments video content into different types or genres (sports, news, entertainment, etc.) and applies different processing parameters to each segment. This segmentation allows the system to use simpler classification rules for each category rather than performing detailed sophisticated analysis on every frame of every program, thereby reducing overall system complexity while maintaining picture quality.
2Loss of energy
If video processing parameters are optimized for each content type, then bandwidth efficiency is improved, but processing time and computational resources increase
Solution Approach 1:
The patent applies preliminary action by pre-classifying content into types and pre-determining optimal processing parameters for each content category. This allows the system to quickly switch between pre-defined parameter sets rather than performing detailed analysis in real-time, thereby improving bandwidth efficiency through optimized compression while minimizing additional processing time.
Solution Approach 2:
The system changes processing parameters dynamically based on content type classification. By having pre-established parameter sets for different content categories (sports, news, entertainment), the system can efficiently adjust parameters to optimize bandwidth usage without requiring time-consuming detailed analysis for each program, thus improving bandwidth efficiency while keeping processing time acceptable.
3Adaptability or versatility
If manual intervention is used to adjust broadcast schedules in real-time, then flexibility and adaptability are improved, but labor requirements and operational complexity increase
Solution Approach 1:
The patent applies self-service by implementing automated systems that can independently adjust broadcast schedules and video processing parameters based on content classification and pre-defined rules. This reduces the need for manual intervention while maintaining schedule flexibility, as the system automatically adapts to different content types and makes appropriate parameter adjustments without requiring operator involvement.
Solution Approach 2:
The patent implements dynamics by creating a system that can automatically and dynamically adjust broadcast schedules and processing parameters in response to different content types. This dynamic automation provides the flexibility previously requiring manual intervention but eliminates the operational complexity and labor requirements, allowing the system to adaptively manage schedules based on real-time content analysis.
