Solution Overview
Problem
Existing television receivers struggle to meet demands for high-value added functions, particularly in distributing high-resolution and high-definition video content and integrating broadband network applications.
Innovation Solution
A broadcast receiving apparatus that supports MPEG Media Transport (MMT) as a media transport method, enabling efficient transmission and processing of video and audio data, along with control information, using MMTP packets and various control messages to facilitate high-definition content distribution and integration with broadband networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional data broadcasting receiving function is utilized, then basic information display is achieved, but high-value added functions and high-definition content distribution cannot be provided
Solution Approach 1:
The patent segments the broadcast signal into multiple independent transport streams, each capable of carrying different types of content (HD video, SD video, data broadcasting). This allows the system to simultaneously support multiple functions and content types without compromising the reliability of each individual stream, resolving the contradiction between versatility and content quality.
Solution Approach 2:
The patent implements a universal broadcast receiving apparatus that can handle both conventional data broadcasting and high-definition video content through a single integrated system. The device universally processes multiple transport streams and can selectively output either data broadcasting information or HD video content based on reception conditions, achieving both high functionality and maintained content quality.
2Manufacturing precision
If high-definition video content is distributed, then video quality is improved, but compatibility with existing data broadcasting functions is reduced
Solution Approach 1:
The patent divides the broadcast content into separate transport streams: one dedicated to high-definition video with high manufacturing precision, and another for data broadcasting with full functionality compatibility. The receiving apparatus can selectively process either stream based on reception environment, thus maintaining both video quality and function compatibility without compromise.
Solution Approach 2:
The system dynamically switches between processing HD video content and data broadcasting content based on reception conditions. When broadcast waves are stable, the apparatus prioritizes HD video output; when data broadcasting is more reliable, it switches to data content processing. This dynamic adaptation maintains both high video quality capability and broad function compatibility.
3Productivity
If broadcast wave reception is used, then content distribution is achieved, but reception stability varies with environment
Solution Approach 1:
The patent segments content distribution into multiple independent transport streams with different characteristics. One stream carries HD video content optimized for stable broadcast reception, while another carries data broadcasting content that can be more reliably received in various environments. This segmentation allows the system to maintain content distribution productivity while adapting to varying reception stability conditions.
Solution Approach 2:
The system changes operational parameters based on reception environment. When broadcast wave reception is stable, it prioritizes HD video content distribution; when reception conditions deteriorate, it switches to data broadcasting content that maintains higher reliability. This parameter adaptation resolves the contradiction between maintaining content distribution productivity and ensuring reception stability.

AI summary
A broadcast receiving apparatus capable of exerting a function with a higher added value is provided. The broadcast receiving apparatus can receive a digital broadcasting service of a broadcasting system adopting a given media transport method, and the broadcast receiving apparatus includes: a broadcast receiving unit that receives a broadcast wave of the digital broadcasting service; a separating unit that separates at least coded program video data related to a broadcasting program, program-cooperation data, and screen layout control information, from the received broadcast wave; a video decoding unit that decodes the coded program video data to reproduce program video information; a cooperation information generating unit that interprets the program-cooperation data to generate program-cooperation information; a presentation processing unit capable of properly dividing a video display region into sub-regions based on the screen layout control information, properly placing the program video information and the program-cooperation information in the divided sub-regions, and outputting data of the video display region as video information; a display unit that displays the video information; an operation input unit to which an operation instruction of a user is input; and a control unit, and when an instruction to display a given screen is input to the operation input unit while the presentation processing unit divides the video display region into the sub-regions based on the screen layout control information, places the program video information in one of the sub-regions, places the program-cooperation information in another sub-region, and outputs the data of the video display region as the video information, the control unit controls the presentation processing unit so as to output information of the given screen as the video information without performing the division of the video display region based on the screen layout control information.
