Recording And Playback Of The Smpte; Time Code - Sony PCM-1630 Operation And Maintenance Manual

1-7-6. Recording and Playback of the SMPTE
Time Code
If a PCM recorded tape has the time code
recorded on it, an edit point can be
located easily, and precise editing is
possible.
When a DMR-2000/4000 recorder which
incorporates a time code generator is used for
recording, the time code is automatically
recorded on the tape's audio channel-2
track simply by connecting the COMPOSITE
DIGITAL OUTPUT connector of the PCM-1630 to
the COMPOSITE DIGITAL (VIDEO) IN connector
of the recorder (connection
(!) ) .
Connection
(!)
supplies a reference signal
for the servo lock, as well as a recording
signal to the recorder.
When a VTR other than the DMR-2000/4000 is
used for recording, a time code generator such
as the Sony BVG-1600 and a time code reader
such as the Sony BVG-1500 are required in
the system. In this case, a composite sync
signal must be supplied from the PCM-1630
to the time code generator in order to
synchronize the time code generator with
the PCM-1630.

To record the time code on a blank tape
When a time code is to be recorded on a
blank tape before recording or editing, it
is recommended that a muting signal be
recorded on the PCM signal track (video
track) simultaneously. To record a muting
signal, set the ENC IN selector of the
PCM-1630 to ANALOG and the REC MUTE switch
on the ENC-2 board of the PCM-1630 to ON.
A muting signal containing sampling
frequency information and emphasis
information is output from the COMPOSITE
DIGITAL OUTPUT connector of the PCM-1630.
Connect the PCM-1630 and the recorder in
the same manner as that used to make the
connection for time code recording/
playback.
Note
After completing the time code recording,
be sure to return the REC MUTE switch of
the PCM-1630 to OFF. If the switch remains
ON, a recording cannot be made.
