A high impedance device connected in parallel to a video source.
A term used to describe the chaining of a video signal through several video devices ( distribution amplifiers, VCRs, monitors, etc.). A VCR may be hooked up to a distribution amplifier which is supplied with a video input connector and a loop output connector. When a signal is fed to the distribution amplifier, it is also fed unprocessed to the loop output connector (parallel connection) on the distribution amplifier. In turn, the same signal is fed to another device which is attached to the first one and so on. Thus a very large number of VCRs or other video devices can be looped together for multiple processing.
This refers to connecting an additional device in parallel with an existing video cable. For example, when driving a video recorder as well as a monitor from the same video signal, simply by T’ing off the cable.
A piece of video equipment that allows video signals to pass through without being terminated.
A video device (switcher, monitor, etc.) that allows video inputs to pass through outputs to other devices without terminating. By looping the signal through a device, one signal can drive several devices.
