Transport Control Mechanism Selection in IGRS AV Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IGRS AV systems, when both SOAP and BCM based transport control mechanisms are supported by media server and media client, there is a need to determine which mechanism to use for stream transport control.
Innovation Solution
An apparatus and method that obtain information on supported transport control mechanisms from both devices and select one based on preset rules, such as user configuration or default settings, without requiring additional messages or interaction processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both SOAP and BCM transport control mechanisms are supported in media server and media client, then the system has higher adaptability and versatility, but the device complexity increases and it becomes difficult to determine which mechanism to use
Solution Approach 1:
The patent applies preliminary action by pre-configuring preset rules for transport control mechanism selection before actual communication occurs. The rules are established in advance based on device capabilities and communication requirements, enabling automatic selection without complex real-time decision-making processes. This resolves the selection complexity by having preparation work done beforehand.
Solution Approach 2:
The system implements self-service through automatic transport control mechanism selection based on preset rules. The media server and media client autonomously determine which mechanism to use (SOAP or BCM) without requiring manual intervention or complex negotiation protocols. The selection is performed automatically based on pre-established rules that consider device capabilities and communication needs.
2Reliability
If additional messages or interaction processes are added to select transport control mechanism, then the selection process becomes more robust, but the communication overhead increases and productivity decreases
Solution Approach 1:
The patent applies preliminary action by pre-configuring preset rules for transport control mechanism selection before actual communication occurs. The rules are established in advance based on device capabilities and communication requirements, enabling automatic selection without complex real-time decision-making processes. This resolves the selection complexity by having preparation work done beforehand.
Solution Approach 2:
The patent merges the transport control mechanism selection process with the existing IGRS AV protocol communication flow. Instead of adding separate selection messages or interaction processes, the selection is integrated into the standard protocol exchange, utilizing existing messages and procedures to convey capability information and make selection decisions. This eliminates additional communication overhead while maintaining robust selection functionality.

AI summary
The present invention proposes an apparatus and a method for selecting a transport control mechanism to be used between a first device (110) and a second device (120). Firstly, a first unit (231) obtains first information indicating the transport control mechanism supported by the first device (210) and second information indicating the transport control mechanism supported by second device (220); then, a second unit (232) selects the transport control mechanism to be used between the first device (210) and the second device (220) on the basis of the first and second information and a preset rule. With the apparatuses and methods provided in the present invention, the problem of how to select the transport control mechanism to be used between the media server and the media client is well solved. Furthermore, by applying the defined messages and the interaction process in IGRS protocols, there is no need for additional messages nor for an additional interaction process.
