Service Specific Information for Multimedia Service Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcasting-communication convergence systems face challenges in delivering service-specific information across heterogeneous networks, including the Internet, due to the lack of a unified standard for service information transmission, leading to increased complexity and inefficiencies in receiver devices.
Innovation Solution
A method and apparatus for transmitting and receiving multimedia services using service-specific information (SSI) that includes service map tables for both multiple and single logical channels, enabling efficient delivery and selection of services across different networks, and supporting asset-related information and MPEG Media Transport (MMT) Package Tables for enhanced guide and asset management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service specific information is transmitted across heterogeneous networks without a unified standard, then network flexibility and compatibility with existing systems are maintained, but receiver device complexity increases and information delivery efficiency decreases
Solution Approach 1:
The patent applies universality by creating a unified SSI transmission standard that can operate across multiple network types (broadcasting networks, telecommunication networks, Internet). The service specific information structure is designed to be network-agnostic, allowing the same standard to serve diverse transmission mediums without requiring separate implementations for each network type, thereby reducing receiver complexity while maintaining broad compatibility.
Solution Approach 2:
The patent introduces an intermediary layer in the form of a standardized SSI transmission framework that mediates between diverse network protocols and the receiver device. This intermediary standardizes the information exchange format, allowing receivers to interact with a unified interface rather than handling multiple network-specific protocols directly, thus reducing device complexity.
2Adaptability or versatility
If multiple different standards are used for service information transmission in heterogeneous networks, then compatibility with various network types is maintained, but information delivery efficiency and channel acquisition time increase
Solution Approach 1:
The unified SSI transmission standard enables a single information structure to serve multiple network types simultaneously. The standard includes network identifier fields that allow the same SSI framework to adapt to different network environments (broadcasting, telecommunication, Internet) without requiring separate standards, thereby reducing channel acquisition time while maintaining heterogeneous network support.
3Productivity
If network-specific service information formats are used, then optimization for specific network types is achieved, but overall system efficiency and accessibility across different networks decrease
Solution Approach 1:
The patent applies local quality by allowing the SSI structure to include network-specific adaptation fields while maintaining a unified overall framework. Different network types can optimize their specific transmission parameters within the standardized structure, achieving local optimization without sacrificing global accessibility. The standard includes optional network-specific descriptors that can be activated based on the transmission medium.

AI summary
A method for receiving a multimedia service is provided. The method includes receiving service specific information for at least one multimedia service provided from different networks, selecting one service based on the service specific information, and receiving the selected service. The service specific information includes one of a first service map table including information about at least one service which is transmitted over a plurality of logical channels, and a second service map table including information about at least one service which is transmitted over a single logical channel. Each of the first and second service map tables includes asset-related information.
