Abbreviations
and Terms Definitions
for the audio and a frame reference to keep the audio timed correctly to the
video or film frame.
Register A memory that holds a time code position or other number. There are 11
dedicated registers (to hold such numbers as the Head, Tail, In and Out points,
etc.) plus 10 memory registers (0 -9) in the MMR-8.
Reshape The process of regenerating incoming time code so that the time code output is
clean and free of noise or other signal distortions.
Resolving The process of regulating the playback speed of a machine through phase
locking a recorded signal on the tape to a fixed reference signal.
Safe No recording can take place since all record enables are locked out.
Sample The reference for the digital audio sample clock in the MMR-8. It can come
Reference from a digital input, from the word clock input, or from the frame reference.
SCSI Small Computer System Interface. The bus that connects external removable
drives to the MMR-8.
Setup Menus The method through which operating parameters are changed and set in the
MMR-8. To bring up the Setup Menus on the LCD display press the Setup key.
Shuttle Manual control over the machine transport from stop to play to fast forward
and from stop to reverse play to rewind through using the Wheel.
Slip The process of adding slight timing offsets to individual tracks.
SMPTE Society of Motion Picture & Television Engineers. The organization that
developed and approved the video time code that is often referred to as SMPTE
or SMPTE/EBU code.
Sync Group Each MMR-8 can be placed into one of four Sync Groups, or groups of
machines that can be controlled together. The Sync Group also selects the
biphase input that is being used.
Sync Word Part of the SMPTE/EBU time code, the sync word indicates the end of the time
code word. It can also be used to determine the direction the transport is
moving as well as for phase locking.
TC Time Code. The 80 bit biphase-encoded code (90 bit code is used in VITC
code) that marks the time on a video or audio tape in
hours:minutes:seconds:frames:subframes. It also identifies the type of code
being used (DF or NDF). It can be recorded longitudinally along the edge of a
tape or recorded within the vertical interval on a video tape. Time code can also
be encoded onto film, although in most applications the time code will be
generated from the film transport biphase signal.
