Broadcast Receiving Apparatus Video Layout Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current television receivers struggle to provide high-value-added functions, particularly in distributing high-resolution and high-definition video content using broadband networks, as existing data broadcasting receiving functions are inadequate for meeting modern content distribution demands.
Innovation Solution
A broadcast receiving apparatus that receives digital broadcast video data and program-cooperation data, using screen layout control information to divide and arrange video, character, graphic, and image information into multiple regions, generating output video information that synthesizes these elements, and controls the display accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data broadcasting receiving function is utilized or extended, then various information can be displayed, but it is difficult to provide high-value-added television receiver capable of satisfying demands for high-resolution and high-definition video contents
Solution Approach 1:
The video display region is divided into a plurality of regions based on screen layout control information, allowing different types of information (program video, character information, graphic information, image information, video information) to be arranged in separate regions. This segmentation enables the system to handle multiple data streams and processing requirements simultaneously, supporting both data broadcasting functionality and high-resolution video output.
Solution Approach 2:
The patent introduces a multi-dimensional processing approach by creating separate processing paths for different information types (program video information, character information, graphic information, image information, video information) and then synthesizing them in a composite video stream. This dimensional separation allows each information type to be processed independently at high resolution before being combined, overcoming the limitations of traditional data broadcasting reception.
2Ease of operation
If screen layout control information is not available, then video display region cannot be divided into multiple regions, but the system must still generate output video information
Solution Approach 1:
The system dynamically adjusts its operation mode based on the availability of screen layout control information. When layout control information is available, the video generating unit divides the display region into multiple regions and arranges different information types accordingly. When layout control information is not available, the system switches to generating only program video information. This dynamic adaptation allows the system to maintain ease of operation in simple modes while providing full adaptability when control information is present.
Solution Approach 2:
The system changes its operational parameters based on the presence or absence of screen layout control information. The video generating unit modifies its processing behavior by changing the set of information types to be processed and arranged, switching between a comprehensive multi-information mode and a simplified program-video-only mode. This parameter-based adaptation resolves the contradiction between operational simplicity and functional versatility.

AI summary
A broadcast receiving apparatus capable of executing a function with a higher added value includes: a receiving unit configured to receive the video data of the digital broadcast program, the program-cooperation data, and the screen layout control information; a video generating unit configured to divide a video display region for a video to be outputted into a plurality of regions on the basis of the screen layout control information, arrange program video information and other information in each of the plurality of regions, and generate video information; a display unit configured to display the output video information; and a control unit which can, where there is no effective screen layout control information control the video generating unit so as not to divide the video display region and to generate the program video information as the output video information until effective screen layout control information is obtained.
