Media Sink Capability Discovery via Direct Address Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 3GPP FLUS protocol lacks a mechanism for providing a direct address to access sink capabilities, limiting interoperability across vendors and requiring vendor-specific capabilities, which hinders the ability of media sources to utilize sink capabilities effectively.
Innovation Solution
A method is introduced to signal the address of a capability in sink capabilities discovery, allowing media sources to obtain and directly access sink resources by including a direct address in the sink resource, enabling direct access to capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the 3GPP FLUS protocol uses vendor-specific capability description without direct address signaling, then the protocol implementation is simpler, but interoperability between different vendors is limited and capability access is indirect
Solution Approach 1:
The capability description is segmented into distinct components: capability identifiers, capability parameters, and direct address information. This segmentation allows each element to be independently processed and accessed, improving interoperability while maintaining protocol structure.
Solution Approach 2:
The patent adds a new dimension to the capability description by including direct address information alongside capability identifiers. This dimensional addition enables direct access to capabilities without requiring complex indirect lookup procedures, thereby improving interoperability without significantly increasing protocol complexity.
2Ease of operation
If the protocol does not provide a specific address for reaching capability, then the data structure is simpler, but the media source cannot directly access sink capabilities
Solution Approach 1:
The direct address information is preliminarily embedded within the capability description data structure during sink capability discovery. This preliminary inclusion of address information eliminates the need for subsequent complex address resolution procedures, enabling direct capability access while maintaining data structure efficiency.
Solution Approach 2:
The capability description serves as an intermediary data structure that bridges the gap between capability identification and direct access. By embedding address information within this intermediary structure, the system enables direct capability access without requiring separate address management mechanisms.
Data Source
AI summary
A method, computer program, computer system, and device is provided for determining media sink capabilities. The method may include obtaining, by a media source, a sink resource associated with a media sink, wherein the sink resource indicates a direct address at which a capability described in the sink resource can be directly accessed; and accessing the capability directly by the media source using the direct address.
