Question: What is the primary purpose of the MCVideo-10 reference point in an interconnected MCVideo system, and which protocol does it utilize for transport and routing of signaling?
Option 1: To transfer media only, utilizing RTP (Real-time Transport Protocol) for transport and routing.
Option 2: For floor control signaling exclusively, using HTTP (Hypertext Transfer Protocol) for transport and routing.
Option 3: For MCVideo application signaling to establish sessions, utilizing SIP-3 (Session Initiation Protocol) for transport and routing of signaling, also transferring floor control signaling and media.
Option 4: To manage user authentication, employing Diameter (Authentication, Authorization, and Accounting) for transport and routing.
Explanation: The MCVideo-10 reference point is defined for establishing MCVideo sessions through application signaling in interconnected systems. It leverages SIP-3 for efficient signaling transport and routing, suitable for real-time communication session management like those required in Mission Critical Video applications, also handling floor control signaling and media transfer.
