A fixed deviation from proper clock phase that commonly appears in D1 digital video equipment. Some digital distribution amplifiers handle improperly phased clocks by reclocking the output to fall within D1 specifications.
Industry:Entertainment
A steady-state signal applied to the tape (usually by a highfrequency oscillation of 50 to 100,000 Hz or more) to minimise distortion and noise and increase frequency response and efficiency in recording.
Every tape formulation has slightly different bias requirements.
Industry:Entertainment
Placing a mike close to the sound source in order to pick up mainly direct sound and avoid picking up reverberant sound.
Industry:Entertainment
The control which regulates the amount of bias mixed in with the signal to be recorded.
Industry:Entertainment
Service that provides decoded text information transmitted with the audio and video signal and displays it at the bottom of the display. See (M) NTSC EIA-608 specification. Transmitted on line 21 of NTSC/525 transmissions, contains subtitling information only. CC has no support for block graphics or multiple pages but it can support 8-colors and the use of an italic typeface. Frequently found on pre-recorded VHS cassettes and LDs, also used in broadcast. Also found on PAL/625 prerecorded VHS cassettes in a modified version.
Industry:Entertainment
A control which calibrates the VU metre on a recorder so it reads 0 VU in the bias position of the output selector switch when bias is properly set.
Industry:Entertainment
The method of transmission of programmes or other material that limits its target audience to a specific group rather than the general public.
Industry:Entertainment
Switch used on a cassette recorder to change the amount of bias current required for different types of tapes.
Industry:Entertainment
Circuit operating with feedback, whose inputs are a function of its outputs.
Industry:Entertainment
A) Indicates that signal flow may be in either direction.
Common bidirectional buses are three-state or open collector TTL.
b) In open reel or cassette recorders, the ability to play (and, in some cases, record) both stereo track pairs on a tape by reversing the tape’s direction of motion without removing and replacing the tape reels or cassette.
