Service Guide Decoding via Segmented Media Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Open Mobile Alliance (OMA) BCAST specification lacks efficient methods for decoding service guides in mobile broadcast systems, which are essential for providing users with comprehensive and user-friendly multimedia content delivery.
Innovation Solution
A method for decoding a service guide by a decoder associated with a media bitstream, involving the receipt and decoding of a service description, service media extension, major channel number, minor channel number, and icon within the service media extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the OMA BCAST specification uses traditional service guide decoding methods, then the decoding process is simple, but the user experience and comprehensiveness of multimedia content delivery are insufficient
Solution Approach 1:
The service guide is segmented into multiple structured elements including service description, service media extension, major channel number, minor channel number, and icon. This segmentation allows the decoder to process comprehensive multimedia information systematically while maintaining a clear and organized decoding process.
Solution Approach 2:
The patent introduces a hierarchical dimension to the service guide structure by organizing information across multiple levels: service description at the top level, service media extension providing additional media-specific information, and detailed channel identification through major and minor channel numbers. This multi-dimensional structure enhances comprehensiveness without complicating the basic decoding approach.
2Loss of information
If the service guide includes detailed channel information and service media extension, then the comprehensiveness of information is improved, but the decoding complexity increases
Solution Approach 1:
The service guide information is divided into distinct segments: service description, service media extension, major channel number, minor channel number, and icon. Each segment serves a specific function and can be processed independently, reducing overall decoding complexity while maintaining information completeness.
Solution Approach 2:
The service guide structure is pre-organized with clear hierarchical relationships and defined element positions before decoding begins. The service media extension and channel number components are structured in advance to facilitate systematic extraction and processing, reducing the computational complexity during actual decoding operations.
