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.



IS-2 ISDN TIMECODE ADAPTER
RS232 AUX CHANNEL USED
Frees Audio channel for Stereo
1200 BAUD
Maximise audio bandwidth
HIGH SPEED, GI-DIRECTIONAL TIME CODE LINK
Up to 10 x Play Speed
DIRECT INTERFACE WITH IS-1
Built in Synchroniser
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.
