Question: What characterizes a Remotely Initiated Video Push to Group in Mission Critical Video (MCVideo) communications?
Option 1: A bidirectional video communication among all group members, initiated by any member of the group.
Option 2: A type of broadcast group call where only the originating user can request a source user to transmit video, ending when transmission is completed or released.
Option 3: A point-to-point video call between two users within the MCVideo network, initiated by network administrators.
Option 4: An autonomous video streaming service that automatically connects all group members without external initiation.
Explanation: This option correctly captures the essence of a Remotely Initiated Video Push to Group as defined in the context of MCVideo, highlighting its unidirectional transmission, specific initiation mechanism, and conditions for call termination, crucial for managing and implementing such critical communication services effectively in telecom networks.
