Question: In a Mission Critical Video (MCVideo) scenario, when an MCVideo client performs a passive join to ongoing group communication, what is the primary condition for this client to synchronize with the existing group, aside from being aware of the group communication?
Option 1: Receiving a dedicated synchronization signal from the network specifically for this client.
Option 2: Receiving periodically sent communication parameters related to the ongoing group communication.
Option 3: Establishing a unicast connection with each member of the existing group.
Option 4: Sending a join request to the group and waiting for explicit approval from all members.
Explanation: In the context of MCVideo passive join, receiving periodically sent communication parameters is crucial for the new client to synchronize with the ongoing group communication without necessarily alerting other members. This ensures seamless integration into the existing video stream, maintaining the continuity and integrity of the mission-critical communication. This approach relies on the pre-shared or broadcast nature of these parameters, facilitating a more streamlined and efficient join process.
