Service Guide Delivery Descriptor for IP Broadcasting Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital broadcasting systems, particularly the IP profile in DVB-NGH, face challenges in efficiently transmitting and receiving signaling information due to the lack of integration with MPEG2 TS-based PSI/SI technology, leading to inefficiencies in network interoperability and service data delivery.
Innovation Solution
A method and apparatus for transmitting and receiving signaling information using a Service Guide Delivery Descriptor (SGDD) in the upper layer of the Internet Protocol (IP) layer, which generates and transmits service guide information including broadcast service data, transmission network details, and neighboring network information, enabling efficient signaling across IP-based networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the IP profile uses a separate method for providing signaling information instead of MPEG2 TS-based PSI/SI, then interoperability with IP networks is improved, but transmission efficiency and system complexity are worsened
Solution Approach 1:
The patent combines service guide information, transmission network information, and physical layer information into a single integrated signaling structure transmitted through IP packets. This merging eliminates the need for separate signaling methods while maintaining IP network interoperability, thereby reducing system complexity without sacrificing adaptability.
2Device complexity
If signaling information is transmitted without integrated service guide delivery, then system simplicity is improved, but delay time in receiving signaling information is worsened
Solution Approach 1:
The patent implements preliminary organization of all necessary signaling information (service guide, network information, physical layer parameters) into pre-configured IP packets before transmission. This preliminary action allows receiving devices to process information more efficiently upon arrival, reducing delay time while maintaining system simplicity through structured data preparation.
3Loss of information
If separate methods are used for transmitting broadcast service data and signaling information, then clarity of information delivery is improved, but transmission efficiency is worsened
Solution Approach 1:
The patent creates a universal signaling transmission mechanism where IP packets serve multiple functions: carrying service guide information, transmission network details, and physical layer parameters simultaneously. This multi-functional approach maintains clear information delivery through structured data fields while improving transmission efficiency by consolidating multiple information types into single transmission units.
