Transition Broadcast Channel for Next-Gen Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Broadcast television service providers face challenges in providing new, non-backwards compatible services due to limited wireless spectrum availability, which hinders the delivery of advanced services like mobile television and ultra-high-definition television while maintaining existing services.
Innovation Solution
A distribution system and reception apparatus that utilize a transition broadcast channel distinct from existing channels to broadcast and receive new services, allowing for the simultaneous transmission of first and second services using different transmission schemes, enabling the rollout of next-generation broadcast television services without interfering with existing terrestrial broadcasts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If broadcast providers use existing broadcast channels to provide new services, then service diversity is improved, but signal interference increases and service reliability deteriorates
Solution Approach 1:
The patent segments the broadcast spectrum by designating specific channels as transition channels separate from traditional broadcast channels. This segmentation allows first services (next-generation services like mobile TV and UHDTV) to be transmitted on transition channels while second services (traditional broadcast services) continue on traditional channels, preventing signal interference and ensuring service reliability for both types of services simultaneously.
2Adaptability or versatility
If broadcast providers allocate more spectrum to new services, then service functionality is improved, but spectrum availability for existing services deteriorates
Solution Approach 1:
The transition channels serve multiple functions: they carry first services (next-generation broadcast services), can also transmit second services during the transition period, and provide a pathway for gradual migration from traditional to next-generation services. This multi-functionality allows the system to support both old and new services without requiring dedicated spectrum for each, thus improving service functionality while preserving spectrum availability.
3Productivity
If broadcast providers implement next-generation services on existing channels, then service performance is improved, but backwards compatibility deteriorates
Solution Approach 1:
Transition channels act as an intermediary between traditional broadcast channels and next-generation service requirements. These channels are specifically designated to carry first services that utilize advanced transmission schemes, while traditional channels continue to carry second services using legacy transmission schemes. This intermediary approach allows next-generation services to achieve improved performance on transition channels while maintaining backwards compatibility on traditional channels during the transition period.
