3D NRT Broadcast Service Identification in Receivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current non-real-time (NRT) broadcast services lack the ability to identify and process 3D content at receiving devices, and fail to provide detailed information about 3D NRT content through electronic program guides (EPGs), limiting user functionality such as viewing and recording.
Innovation Solution
A method for processing NRT services in broadcast receivers, which involves receiving signaling information, identifying 3D content using service map tables and NRT-information tables, and processing the service to determine the presence of 3D content, allowing for detailed information display in EPGs and user functions like viewing and recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If NRT broadcast services transmit content without 3D identification capability, then the service can be implemented with basic functionality, but the receiving device cannot identify or process 3D content, limiting service versatility
Solution Approach 1:
The patent segments the service identification process by introducing separate indicator fields in signaling tables (SMT and NRT-IT) that specifically identify 3D content. This allows the receiving device to distinguish 3D content through dedicated flags rather than analyzing entire content streams, enabling 3D processing capability while maintaining manageable system complexity through structured signal segmentation.
2Ease of operation
If detailed 3D content information is not provided through EPG, then the system maintains simple guide functionality, but users cannot access detailed information about 3D NRT content, reducing ease of operation
Solution Approach 1:
The patent implements preliminary action by pre-processing and tagging 3D content information during the broadcasting phase. The service map table and NRT information table are prepared in advance with 3D indicators and detailed content metadata, allowing the EPG to display comprehensive 3D content information without requiring complex real-time analysis at the receiving device, thus improving user access while maintaining information completeness.
3Adaptability or versatility
If the system does not provide version correspondence information, then the service structure remains simple, but users cannot download alternative versions (2D/3D) of content, reducing adaptability
Solution Approach 1:
The patent applies the nested doll principle by embedding version correspondence information within the existing service map table structure. The SMT contains nested descriptors that link to alternative versions (2D/3D) of the same content, allowing the system to provide comprehensive version availability while maintaining a hierarchical, organized table structure that manages complexity through nested information organization rather than flat, unwieldy data structures.

AI summary
The present invention relates to a non-real-time broadcast service processing system and a processing method thereof. According to the present invention, the method for processing a non-real-time (NRT) service in a broadcast receiver enables the NRT service to be processed with the following steps: receiving a broadcast service and signaling information; identifying whether the broadcast service is the NRT service on the basis of the signaling information; and identifying whether the identified NRT service includes a 3D service or a 3D content.
