Subcarrier
A sine wave imposed on the luminance portion of a video signal and modulated to carry color information. Its amplitude represents color saturation and its phase, hue.
Superimpose
To put a set of characters onto a picture so that both can be seen at the same time.
Superimposition
Superimposing a signal onto another signal.
A signal format in which Y (luminance) and C (chrominance) signals are separated to reduce interference between them so that noiseless images are reproduced.
Sync signal
A reference signal consisting of vertical and horizontal sync signals used for synchronizing the scanning patterns of the video camera and the monitor.
TBC
Abbreviation of Time Base Corrector. Electronic circuits to electrically stabilize the playback signals by removing color variation and roll in the playback picture caused by irregularity in drum rotation and tape movement. Time base correction reduces deterioration of picture quality when transmitting or copying playback signals.
Threading

Time code
Signals recorded on the tape to supply information on tape position such as the hour, minute, second and frame, to assist in setting edit points or searching for particular scenes. This unit can cope with both DF (Drop Frame) and NDF (Non Drop Frame)
Unloading
When being unloaded, the tape is put into the cassette case from the tape path of the VCR. Generally, this is done automatically when you press the EJECT button. Also called unthreading.
Unthreading

12 bit (Fs32k) mode
In the DVCAM format, the 12 bit (Fs32k) mode separates the audio area into 2 parts. You can record two kinds of audio, stereo 1 and stereo 2.
16 bit (Fs48k) mode
In the DVCAM format, the 16 bit (Fs48k) mode uses the whole audio area to record one stereo track. You can get higher sound quality.
