Digital Broadcast Receiver Managing 2K and 4K Service Lists
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital broadcasting systems face challenges in seamlessly transitioning to advanced services like UHD while maintaining compatibility with existing infrastructure and viewing environments.
Innovation Solution
The system employs multiple receivers to detect and process both 2K and 4K broadcasting services through frequency scanning, creating service lists and storing them in memory, allowing for simultaneous reception and transmission of advanced digital broadcasting services without disrupting existing services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an advanced digital broadcasting service (UHD/4K) is introduced to improve broadcasting quality and functionality, then broadcasting quality and resolution are improved, but compatibility with existing digital broadcasting service (2K) deteriorates
Solution Approach 1:
The receiving apparatus is designed to support multiple broadcasting standards (2K and 4K) simultaneously through a unified service list management system. The apparatus can detect, manage, and receive both existing digital broadcasting services and advanced digital broadcasting services, making it universally compatible across different broadcasting generations without requiring separate reception systems.
Solution Approach 2:
The service list is designed to be dynamically expandable to accommodate different service types. The system can adaptively manage service lists for different broadcasting standards (2K and 4K) and switch between them based on detection results, allowing the system to evolve from supporting only existing services to supporting advanced services without losing backward compatibility.
2Manufacturing precision
If a system replaces existing digital broadcasting with advanced digital broadcasting to achieve higher resolution, then broadcasting resolution is improved, but viewing environment of existing service deteriorates
Solution Approach 1:
The service list is segmented into different categories (existing digital broadcasting service and advanced digital broadcasting service) based on detection results. This segmentation allows the system to separately manage and present services according to their type, enabling users to access both 2K and 4K services through a unified interface without disruption to existing viewing environments.
Solution Approach 2:
The service list acts as an intermediary between the receiver and multiple broadcasting standards. It provides a unified access point that translates user requests into appropriate service types, allowing seamless transition between existing and advanced services while maintaining a consistent user interface and viewing environment.
3Measurement precision
If frequency scanning is performed to detect broadcasting services, then service detection capability is improved, but time consumption increases
Solution Approach 1:
The receiver performs frequency scanning to detect broadcasting services in advance and creates service lists before user access is needed. By pre-detecting and categorizing services (2K and 4K) into organized service lists, the system eliminates the need for time-consuming scanning operations when users want to access services, significantly reducing access time while maintaining comprehensive detection capability.

AI summary
A technique for transmitting or receiving an advanced digital broadcasting service more preferably is provided. One or a plurality of receivers detect a 2K broadcasting service that transmits a 2K broadcasting program by performing a frequency scan for a received broadcast wave and create a service list of the 2K broadcasting service by using information related to the detected 2K broadcasting service, the one or plurality of receivers detect, after the detection of the 2K broadcasting service, a 4K broadcasting service that transmits a 4K broadcasting program by performing a frequency scan for the broadcast wave and create a service list of the 4K broadcasting service by using information related to the detected 4K broadcasting service, and a memory stores a service list obtained by composing the created service list of the 2K broadcasting service and the created service list of the 4K broadcasting service.
