The CB ISDN Synchroniser is a custom version of the CB SS-2
Video Synchroniser that combines a video synchroniser with a
RS232 ISDN interface, this addition enables the video to slave
either to timecode in the normal way or to timecode received via
the ISDN line. By using the RS232 Aux channel instead of one of
the Audio channels it is now possible to send STEREO audio and
timecode over ONE ISDN link. By including the RS422 machine
control and synchroniser no additional hardware is required to
make a full sound/video link-up over an ISDN line.
The Preferred system requires one IS-1 unit at each end of the
ISDN link, this provides bi-diretional timecode and machine
control. The advantage of the system is that a single trained
operator can control instant high quality monitoring synchronous
with picture in two locations. However a sigle unit may be used
either as a stand alone synchroniser to lock the local video
machine to a remote source of timecode, or to buffer the local
timecode before the isdn line, this allows high speed timecode to
be transmitted as bursts of play speed code.

MASTER
The master unit reads timecode and transmits both the code and
the remote switch information via the ISDN line. The REMOTE
tallies are driven from information received from the slave, in
this way the operator at the MASTER unit knows what is happening
to the slave. The master unit may also be used to slave a video
machine to the timecode. |
SLAVE
The slave unit genlocks its generator to the ISDN information and
uses that timecode to slave a video or dat machine. The machine
position and status are transmitted via the ISDN line to be used
as tally information by the MASTER unit. The timecode output may
be used by external equipment. |

Provides a bi-directional timecode link via the RS232 aux
channel to any suitable ISDN digital audio compander system
(Dolby Fax, APT and CCS). Usin the RS232 Aux channel instead of
one of the Audio channels it is now possible to send STEREO audio
and timecode over ONE ISDN link
The minimum system requirements are either two IS-2 units or
one !S-2 at one end of an ISDN link and an IS-1 combined
synchroniser and ISDN link at the other. The high speed timecode
lin is bi-directional and standard independent.

Typically studios such as Disney, 20th Century, Skywalker,
etc. often deploy one of their many units along with one of their
DolbyFaxes at a musician or composer's location while they are
working on a production, the IS-1 synchronizes to an AVID so they
can hear temp music in sync from the composer/musicians studio to
their cutting rooms.
Tom Scott of EDNET has updated his helpful notes on the use of
the IS-1.
