4K Broadcast Receiver Switching for 2K and IP Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital broadcasting systems do not adequately consider compatibility with legacy systems when transitioning to advanced digital broadcasting services like UHD, potentially disrupting existing viewing environments.
Innovation Solution
A broadcast receiving apparatus capable of receiving both 4K and 2K broadcasting services, with display switching processes prioritized to maintain compatibility, allowing seamless transition between services in case of reception defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If advanced digital broadcasting service (4K) is implemented, then broadcasting quality is improved, but compatibility with existing digital broadcasting service (2K) is compromised
Solution Approach 1:
The broadcast receiving apparatus is designed to support multiple broadcasting services (4K and 2K) simultaneously through a single receiver, enabling one device to perform multiple functions. The system can adaptively select and process different service types based on reception conditions, maintaining both advanced quality and broad compatibility
2Manufacturing precision
If 4K broadcasting service reception is prioritized, then viewing quality is improved, but service reliability deteriorates due to potential reception defects
Solution Approach 1:
The system prepares backup reception paths in advance by monitoring reception quality metrics (BER, MER) and automatically switching to alternative services (2K broadcasting or IP simultaneous broadcasting) when defects are detected. This preemptive approach ensures continuous service without interruption, cushioning against potential reception failures

AI summary
A display controlling method for a broadcast receiving apparatus allowed to receive IP simultaneous broadcasting of a 4K broadcasting service via a communication transmission line, in which simultaneous broadcasting of the 4K broadcasting service and a 2K broadcasting service is executed by a broadcasting wave, is configured to: receive and demodulate the 4K broadcasting service, and display a broadcasting program of the 4K broadcasting service; and select and execute one display switching process of first and second display switching processes in accordance with priority order in a case where a defect occurs in reception, demodulation, or display of the 4K broadcasting service, the 2K broadcasting service being received and demodulated to display a broadcasting program of the 2K broadcasting service in the first display switching process, the IP simultaneous broadcasting being received and demodulated to display a program of the IP simultaneous broadcasting in the second display switching process.
