musical pitch and rhythm information, synthesizer performance
parameters, song position markers, stop/start/continue commands
for sequencers and computers, and synchronizing data called MIDI
Clock, which is based on 24 pulses per quarter-note. MIDI is
frequently used with SMPTE for sync-to-tape functions.
MIDI is transmitted between microprocessors at 32.125 KBits per
second. It can also be used by lighting systems and mixing
consoles.
MTC. MIDI Time Code.
Non Drop Frame. NDF or ND is one of the two SMPTE code types
and is the black & white television standard. When using this code
type, every frame of time code is counted in real time.
NTSC. A system of coding color information for television trans-
mission used primarily in the USA and Japan. Named after the
National Television System Committee.
Offset. Offset is the difference between two time codes at the point
at which they are to be synchronized. Offsets are subframe-
accurate and are displayed using the HH:MM:SS:FF format.
PAL. Phase Alternate Line. PAL is another name for the 25 time
code format, which is the standard for European color and B&W
television.
Phase Lock. A mode of synchronizer operation that uses phase
information derived from SMPTE time code and after initial
synchronization, ignores specific frame addresses. It is also called
Sync Lock.
Post-production. Activities that take place after the raw footage
has been shot for a video program or motion picture. Includes
video editing and a number of audio processes, such as ADR,
Foley, and mixing.
Production. The initial stages in the making of a film or television
program, which includes the shooting of raw footage and recording
of production audio.
RAM. Random Access Memory. The module's configuration
parameters are stored in battery-backed RAM. And recalled each
