The home of the PAL system
- The is the little bit of mechanism which transfers drive to the
cassette reel spools. See also the idler page.
- This is term which refers to editing operations which do not
lay down a new control track. This type of editing opertion requires the use
of a pre-striped tape (tape on to which a continious control track has been laid).
- IMEX machines
- A tape format that uses the Betacam cassette shell and basic tape path
design. The system records MPEG video. These
machines are often also capable of Betacam, Betacam SP, Digital
Betacam and Betacam SX playback.
- A process in which the picture is split into two fields by
sending all the odd numbered lines to field one and all the even
numbered lines to field two. This was necessary when there was not
enough bandwidth to send a complete frame fast enough to create a
- The International Teleproduction Society.
- The International Television Association.
- Tape transport function allowing frame advance/retard of tape. Used for
- K - Connector
- This is Sony's standard camera connector. See also the
- A machine-readable code printed on the edge of motion picture
film which allows the film edge numbers to be electronically read and
inserted into an edit list. Very useful for generating a negative cut
list from a video off-line EDL.
- Series of Sony U-matic tape intended for Standard U-matic use.
See also the U-matic tape page.
- Prefix used to identify large size U-matic cassette tapes.
See also the U-matic tape page.
- Prefix used to identify small size U-matic cassettes intended for
use in portable units.
See also the U-matic tape page.
- Linear Audio (Track)
- This refers to the standard audio track which is recorded along
the side of the cassette tape rather like on an audio cassette. Audio
recorded in this way suffers from the fact that the tape speed is
rather slow and hence has limited frequency bandwidth. Also referred
to as the longitudinal track.
- Linear Stereo
- This refers to
the system whereby stereo sound was recorded onto the linear audio
track. This was achieved by making the individual audio tracks very
narrow so as to occupy the same width on the tape as the original
monaural track. See also the Betamax linear stereo feature.
- Long Play
- This is mode Beta
III in which the tape speed is reduced in order to allow more material
to be fitted on to a fixed length tape. It was never implemented on
PAL Betamax machines.
- LNG recording
- Abbreviation of longitudinal recording. A method of recording audio
signals by radio frequency bias method on the longitudinal track of
the tape using the fixed head.
- Abbreviation of Longitudinal Time Code. A time code recorded in a
separate track at the edge of the tape.
- Lo-Band U-matic
- The standard U-matic format in which the luminance FM deviation is from 3.8 to 5.4 MHz and the colour under frequency is 685 kHz.
- LTC Linear Time Code
- Time code recorded on a linear analogue track on
a video tape. Also called Longitudinal Time Code.
- Placing a wide screen image on a conventional TV by placing
black bands at the top and bottom of the screen.
- The black and white, or brightness, part of a component
video signal. Also called the "Y" signal.
- This is the recodring VTR in an edit suite. To function as a master machine
a VTR needs to be capable of insert editing.
- A black & white high contrast image that suppresses or cuts a
hole in the background picture to allow the picture the matte was made
from to seamlessly fit in the hole.
- 1 million bytes.
- Metal tape
- Magnetic tape coated with microscopic particles of metal dispersed in
a liquid binder. It allows high density recording. Moisture
condensation Condensation of moisture on the tape transport
mechanisms. If moisture condenses on the head drum, the tape adheres
to the drum and causes malfunction.
- Mini Jack
- This is a small connector normally used for a microphone input or
possible connection of a wired remote control.
- Mode (U-matic)
- This is the way in which a U-matic can operate. Options include,
local, TBC and edit.
- This is the device which takes a baseband video signal and converts
it into a Radio Frequency signal which can be received by a television set.
- This refers to a professional video display unit. Like a TV but without the tuner.
- Monitor Output
- This is an audio output on the rear of the VTR which is used to monitor
- Monitor Selector
- This is the control on the front of the VTR whcih selects which audio
tracks appear on the headphone and Monitor output sockets.
- Moving Picture Experts Group. A group of standards for
compressing moving pictures. MPEG 1 uses a data rate of 1.5 Mbps (Mega
Bits per Second), the speed of CD-ROM. MPEG 2 supports higher quality
with a data rate (also called bit rate) of from 2 to 10 Mpbs. MPEG 2
is the format used for satellite broadcasting (DSS), digital
terrestrial broadcasting, and DVD.
- MTS Stereo
- This is a broadcast stereo system used in the USA.
- This refers to the ability of a particular VCR to work with more than
one video format standard. E.g. both PAL, as used in Europe, and NTSC, as
used in the USA.
- This is the 8-pin DIN connector which
you will find on the SL-C9 and TT-F1. It
is a combined audio and video conection which was also adopted on Sony
Profeel series of monitors and accessories.
- NTSC National Television Systems Committee. The name of the television
and video standard in use in the United States. Consists of 525
horizontal lines at a field rate of 60 fields per second. (Two fields
equals one complete Frame). Only 486 of these lines are used for
picture. The rest are used for sync and extra information such as VITC
and Closed Captioning. This is the colour video standard used in the United
States and Japan. Compare with PAL and SECAM.
- Non-drop-frame mode
- A mode of advancing the time code in such a way that the difference in
frame values between real time and the time code is neglected. Using
this mode produces a difference of approximately 86 seconds per day
between real time and time code, which causes problems when editing
programs in units of seconds using the number of frames as a
- Non-Linear Editor
- An editing system based on storage of video and
audio on computer disk, where the order or lengths of scenes can be
changed without the necessity of re-assembling or copying the program.
