3.1 Definitions

For the purposes of the present document, the terms and definitions given in 3GPP TR 21.905 [1] and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP TR 21.905 [1].

MCVideo Quality: a measure of the distortion or artefacts in a video signal which impacts the ability of a Mission Critical Organisation to utilise the video for its intended purpose. For example if the purpose of the video is to capture license plates on vehicles in a range of outdoor conditions, video quality is measured in the ability of the video outputs to provide the specific information across a range of environmental conditions.

Real Time: Of or relating to systems that update information at the same rate as they receive data, enabling them to direct or control a process such as video recording and display. Sometimes referred to as live or real life timing of events.

Real-Time Video: Video viewed at the same time it is being shot.

Robot: A machine that can perform a task automatically or via remote control such as an unmanned vehicle that can be aerial (e.g., Unmanned aerial vehicle (UAV), aerial drone), aquatic (e.g., unmanned surface vehicle (USV)), submarine, (e.g., unmanned underwater vehicles (UUV), underwater drone) or terrestrial (unmanned ground vehicle (UGV)).

NOTE: Unmanned vehicles typically have a set of sensors to observe the environment, and either autonomously make decisions about their behavior or pass the information to a human operator at a different location who controls the vehicle through teleoperation.
