Smart Brick Brain.
LaserDisks are available in two different recording for-
mats. These are Constant Angular Velocity (CAV) and
Constant Linear Velocity (CAV). Either can be made to
work, but the CAV format is preferred. It is the only format
in which all of the LaserDisk players’ commands are sup-
ported
2) Smpte: (pronounced “SIMP-T“) is a time code which was
developed by the Society of Motion Picture and
Television Electronics for use in audio, film, and television
production. It is normally recorded on a spare audio
track on the medium being used (audio tape, video
tape, or film), and then used to synchronize various
pieces of compatible equipment together. As an indus-
try standard, virtually every audio, video or film studio will
have the equipment to lay down a Smpte time code
track.
Smpte is usually recorded at thirty frames per second
(although twenty-five frames per second is used in
Europe and places where this is the normal television fre-
quency, and twenty-four frames per second is occa-
sionally used in film production). What this means is that
thirty (or twenty-four or twenty-five) times each second a
number is recorded on the tape or film which represents
the hours, seconds, minutes and frame (00:00:00.00)
represented by this particular little stretch of medium.
Since each little stretch is represented by a unique num-
ber, Smpte is known as an ‘absolute’ time code. No mat-
ter where the tape is, the Smart Brick Brain will instantly
evaluate the numbers it gets from the Smpte time code,
and play the appropriate animation data.
With Smpte synchronized shows, the Smpte ‘hour’ is
used to tell the Smart Brick Brain which show it is actually
