Final answer:
A remote video terminal (RTV) enables an end-user to control a video system from a remote location, providing convenience and accessibility.
Step-by-step explanation:
The statement in the question is true. A remote video terminal (RTV) enables an end-user to control a video system from a remote location. It allows the user to access and interact with the video system without physically being present at the location.
For example, a TV remote control is a common type of RTV that allows users to change channels and adjust settings without having to go to the TV and press the buttons directly. Similarly, in video conferencing systems, a remote video terminal enables participants to connect and communicate with each other from different locations.
It's important to note that while RTVs offer convenience, they require compatible infrastructure and connectivity to function properly.
A Remote Video Terminal (RVT) does not necessarily enable an end-user in the context of handheld TV remotes, which is what appears to be referenced in the question. A traditional TV remote, often used for changing channels or adjusting settings, transmits signals using infrared or Bluetooth.
With infrared remotes, a direct line of sight is needed between the remote and the TV's receiver. Bluetooth remotes, however, can operate without the need for this direct line of sight, offering more convenience. Additionally, old television sets often used Cathode Ray Tube (CRT) technology, which has mostly been replaced by modern flat screen technologies that provide better picture quality and take up less space.
