Innovation Solution
A system and method for managing channel mapping using a broadcast channel list and switched digital video protocols, which automatically creates broadcast linear QAMs aligned to channel map tuning triplets, reducing manual configurations and maintenance windows, and supporting both switched and non-switched digital video systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional RF combiner networks are used to deliver video and data streams independently, then video and data services can be delivered with a fair degree of independence, but channel mapping management becomes complicated and error-prone as network architectures evolve
Solution Approach 1:
The patent introduces a channel map generator as an intermediary component that automatically generates channel maps for video services. This mediator component simplifies the complex interaction between evolving network architectures and channel mapping requirements, allowing the system to adapt to new architectures without increasing manual management complexity
Solution Approach 2:
The system implements self-service through automatic channel map generation and distribution. The channel map generator automatically creates and distributes channel maps to customer premise equipment without requiring manual configuration, enabling the system to self-adapt to network evolution while maintaining simple management processes
2Reliability
If manual configurations are used for channel mapping, then configuration accuracy can be maintained, but maintenance time and error rates increase
Solution Approach 1:
The automatic channel map generation system performs self-service by autonomously creating and distributing channel maps. This eliminates manual configuration tasks, maintaining high configuration accuracy through systematic generation while dramatically reducing maintenance time and human error
Solution Approach 2:
The patent replaces manual mechanical configuration processes with automated digital generation. The channel map generator uses digital processing to automatically create channel maps, substituting the manual mechanical process of configuration with an automated system that is both faster and more accurate
3Adaptability or versatility
If channel maps are manually configured for different customer premise equipment types, then equipment-specific requirements can be met, but system scalability is limited
Solution Approach 1:
The channel map generator implements universality by creating a single system that serves multiple customer premise equipment types. The generator automatically adapts channel maps to different equipment requirements without requiring separate manual configuration processes for each equipment type, enabling scalable deployment across diverse networks
Solution Approach 2:
The system uses parameter changes to adapt channel maps to different equipment types. The channel map generator modifies parameters such as frequency ranges, channel allocations, and mapping parameters automatically based on the target equipment type, enabling scalability while maintaining equipment-specific optimization without manual intervention
