MOTU Micro Lite [135/166] Jam sync

APPENDIX A: GLOSSARY

135

Jam Sync: The process of creating fresh, error-free time

code or extending existing time code on tape by locking a

time code generator to existing code.

LT C : Longitudinal Time Code. The Society of Motion

Picture and Television Engineers (SMPTE) time code

format, expressed in audio form as an 80-bit binary audio

signal, that describes the location of each frame on ﬁlm,

video, or audio tape in hours, minutes, seconds, and

frames. LTC’s video counterpart is VITC (Ver t i c a l Inte r v a l

Time Code), which is the same time code format in the

form of a video signal. In audio production, LTC is often

referred to as SMPTE or SMPTE time code since VITC is

seldom used.

MIDI: Musical Instrument Digital Interface. An

information protocol developed in the early 1980’s by

synthesizer and electronic instrument manufacturers to

allow devices to communicate musical performance data

to one another.

MTC: MIDI Time Code. A form of time code, digitized

within the MIDI format, that expresses time in hours,

minutes, seconds, and frames, just like SMPTE time code

(LTC and VITC).

Network: Two MIDI Time Pieces connected via their

NETWORK serial ports with a mini-DIN 8 cable.

Non-drop Frame: A SMPTE time code format that does

not drop any frames. Its counterpart, Drop Frame, skips

over the ﬁrst two frames of every minute (except every

10th minute). Non-drop is the least confusing format and

should be used unless Drop Frame is required. Drop-

frame is required only with color video programs in which

the SMPTE time code numbers must precisely match the

actual elapsed time.

NTSC: National Television Systems Committee Format. A

system of coding color information for broadcasting

television formulated by the NTSC. NTSC uses 30 frames

per second for black and white and 29.97 frames per

second for color.
