Electronic device that corrects timing inconsistencies in a videotape recorder's playback, stabilizing the image for optimum quality. Also synchronizes video sources, allowing image mixing. (See Sync).
Video tape recorder (VTR) playback circuitry used to smooth out the wavering edges of a video image.
Device performing a Time Base Correction function often with many other features, e. g. Transcoding function as well as noise reduction. Synonyms: TBC
(abbreviation"TBC") A special electronic curcuit to smooth out a video signal, and compensate for the fluctuations in record and playback, not unlike the wow of a tape deck when the batteries are going flat. There are two kinds of TBC - the first is known as a "finite TBC", because it stores only a limited number of lines and processes less than a full frame of video, while the second which is more expensive and known as an "infinite TBC", stores an entire frame and can handle greater variances of error. Most units designed for computer-based video systems have infinite windows.
a device/circuit that is used to maintain signal integrity when playing back an NTSC or PAL video signal from a tape where the recording mechanism is analog
Device to correct timing errors which can cause unstable edits. These errors are caused by the slight mechanical defects inherent in the playback of video tape machines.
A device for removing jitter (time base errors) from the signal played back by a VTR (essential if using a special effects generator/vision mixer).
An electronic device with memory and clocking circuits used to correct video signal instability during the playback of video tape material.
An electronic circuit that aligns unsynchronized video signals before signal processing. Used in multiplexers and quad splatters.
