Question: What is the primary purpose of the MCVideo-8 reference point between the Media Distribution Function and the Media Mixer in Mission Critical Video (MCVideo) architecture?
Option 1: To establish a unicast connection for video streaming from the MCVideo client to the MCVideo server.
Option 2: To send multicast media from the Media Distribution Function of the MCVideo server to the Media Mixer of the MCVideo client.
Option 3: To manage session setup and teardown between the MCVideo server and multiple MCVideo clients.
Option 4: To provide QoS (Quality of Service) feedback from the Media Mixer to the Media Distribution Function.
Explanation: The correct answer, Option 2, accurately reflects the primary purpose of the MCVideo-8 reference point as defined in the context of Mission Critical Video architecture. This reference point utilizes multicast for sending media, crucial for efficient video distribution to multiple recipients in mission-critical scenarios.
