Digital Broadcast Reception Device for 2D/3D Program Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital broadcast receivers lack the ability to distinguish between 2D and 3D program content, leading to user inconvenience as they cannot determine if a program is 3D or not.
Innovation Solution
A reception device that receives program content with identification information indicating whether it is 2D or 3D and controls the display accordingly, using descriptors and tables like PMT, EIT, and SDT to identify 3D programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a digital broadcast receiver processes program content without 3D identification information, then the receiver maintains simplicity and compatibility with existing systems, but the user cannot distinguish between 2D and 3D programs
Solution Approach 1:
The patent introduces identification information as an intermediary element between the program content and the user. This information is embedded in the program stream and serves as a mediator that enables the receiver to distinguish 3D programs from 2D programs without fundamentally changing the receiver's architecture. The identification information acts as a bridge that allows users to make informed decisions about program type while maintaining receiver simplicity.
Solution Approach 2:
The patent segments the program information into distinct components: program content, program information, and identification information. By separating the identification function from the content processing function, the receiver can maintain its basic simplicity while gaining the ability to distinguish 3D programs. The identification information is processed independently from the main video/audio stream, allowing minimal impact on receiver complexity.
2Measurement precision
If the receiver displays 3D program content without clear identification, then the display function remains simple, but users cannot accurately identify whether a program is 3D or 2D
Solution Approach 1:
The patent applies preliminary action by providing identification information about 3D programs before the user needs to make a decision. The identification information is made available in advance through program information tables (such as EIT - Event Information Tables) so that users can accurately identify whether an upcoming program is 3D or 2D before selecting it. This eliminates the need for complex real-time analysis during program selection.
Solution Approach 2:
The system provides feedback to the user through clear display of identification information that indicates whether a program is 3D or 2D. This feedback mechanism allows users to accurately identify program types without requiring complex processing. The identification information is displayed in a way that provides immediate and clear feedback to the user about the program characteristics, enabling informed selection decisions.
3Adaptability or versatility
If the receiver uses existing program information tables (PMT, EIT, SDT) without 3D-specific extensions, then the receiver maintains compatibility with current broadcast standards, but it cannot provide accurate 3D program identification
Solution Approach 1:
The patent applies universality by extending existing program information tables (PMT, EIT, SDT) to serve multiple functions: they continue to provide basic program information compatibility while simultaneously enabling 3D program identification. The identification information is integrated into the existing table structures in a way that maintains compatibility with current broadcast standards while adding new capabilities. This allows the receiver to support both legacy 2D programs and new 3D programs using the same information infrastructure.

AI summary
Previously, users could not be notified when the 3D mode type of a program being received by a digital broadcast receiver was not compatible with the digital broadcast receiver. A reception device is provided with: a reception unit which receives program content including video information and identification information including information for distinguishing whether the program content is 2D program content or 3D program content; and a display control unit which controls the display so as to display whether the aforementioned program content is 2D program content or 3D program content in response to the received aforementioned identification information.
