Question: What characterizes a Remotely Initiated Video Push in Mission Critical Video (MCVideo) communications?
Option 1: A public call allowing bi-directional video transmission between multiple users.
Option 2: A private call where only the destination user can transmit video to the source user.
Option 3: A group call enabling simultaneous video sharing among all participants.
Option 4: A private, one-way video transmission from a source user to a destination, initiated and controlled by an authorized remote user.
Explanation: This is correct because Remotely Initiated Video Push is specifically defined as a private call that allows only the source user to transmit video to the destination, with the call being initiated and potentially ended by an authorized remote user. This highlights its application in scenarios requiring controlled, one-way video dissemination, such as emergency response situations where centralized control is crucial.
