Question: What characterizes a Broadcast Group Call in Mission Critical Video (MCVideo) communications, specifically regarding user interaction and call duration?
Option 1: Recipients can request additional media during the call, extending its duration.
Option 2: The initiating MCVideo user expects no response from recipients, and the call ends with media transmission completion.
Option 3: All recipients must acknowledge before the media transmission begins.
Option 4: The call remains open for a fixed period after media transmission for potential questions.
Explanation: In MCVideo communications, a Broadcast Group Call is distinct because it does not require or expect any response from the receiving users to either initiate or sustain the media transmission. Once the initiating user completes the media transmission, the call is considered concluded, highlighting a one-way communication intent. This characteristic aligns with emergency or announcement scenarios where feedback is not necessary.
