EPG Display Control for Simultaneous 2K and 4K Broadcast Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital broadcasting systems do not adequately consider compatibility with existing digital broadcasting services when transitioning to advanced digital broadcasting services, such as UHD, potentially disrupting the viewing environment.
Innovation Solution
A broadcast receiving apparatus is configured to identify and manage the simultaneous broadcasting of 2K and 4K services, adjusting the display state of program information based on control information in the received broadcasting wave, ensuring compatibility with both services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an advanced digital broadcasting service (UHD) is implemented, then broadcasting quality and resolution are improved, but compatibility with existing digital broadcasting service is compromised
Solution Approach 1:
The broadcasting service is segmented into multiple resolution versions (2K and 4K) that can be independently received and displayed. The system divides the service content into different quality levels, allowing receivers to access the version compatible with their capabilities while maintaining the option for higher quality where supported.
Solution Approach 2:
The broadcast receiving apparatus is designed with multi-functional capability to receive and process both existing digital broadcasting services (2K) and advanced services (4K). The controller identifies and adapts to different service types, making the device universally compatible across service generations.
2Adaptability or versatility
If simultaneous broadcasting of 2K and 4K services is implemented, then adaptability to different resolution requirements is improved, but complexity of managing multiple services increases
Solution Approach 1:
The controller continuously monitors control information in the received broadcasting wave to identify whether simultaneous broadcasting of 2K and 4K services is executed. Based on this feedback, the system automatically adjusts its reception and display behavior, selecting the appropriate service version without requiring complex manual configuration.
Solution Approach 2:
The broadcast receiving apparatus autonomously manages the complexity of simultaneous 2K and 4K broadcasting by automatically identifying service types through control information and self-adjusting its reception parameters. The system performs self-service configuration, eliminating the need for user intervention in managing multiple service resolutions.
3Loss of information
If EPG screen displays information for both 2K and 4K services, then information completeness is improved, but clarity and user understanding may be compromised
Solution Approach 1:
The EPG screen display applies local quality differentiation by showing distinct visual indicators for 2K and 4K service information. The controller changes display states specifically for program information related to different resolution services, providing localized visual cues that help users distinguish between service types without overwhelming the entire interface.

AI summary
A technique of transmitting or receiving an advanced digital broadcasting service more suitably is provided. As the means, a broadcast receiving apparatus for receiving a broadcasting wave, a 2K broadcasting service and a 4K broadcasting service being transmitted by the broadcasting wave, includes: a receiver configured to receive the broadcasting wave; a display; and a controller. The controller is configured to identify whether simultaneous broadcasting of a 2K broadcasting service and a 4K broadcasting service in the broadcasting wave is executed or not on a basis of control information, the control information being contained in the broadcasting wave received by the receiver. In a case where an EPG screen for the 2K broadcasting service and the 4K broadcasting service included in the broadcasting wave received by the receiver is to be displayed on the display, the controller is configured to change a display state in the EPG screen of program information on any one service of the 2K broadcasting service or the 4K broadcasting service at least included in the broadcasting wave in accordance with the identifying result.
