VBI Data Inserter

 Inserts data into SDV
 Bypass relay
 Ideal for Analogue VBI systems
 Multiple Analogue input capability
 Advanced syncs output

The INS-S VBI Data inserter provides a means of adding analogue VBI signals into a serial digital video signal,
this allows existing analogue VBI generation equipment to continue to be used in digital systems. It has a Y only
analogue to digital converter to allow the analogue VBI signal to be inserted into the selected lines of the serial
digital video signal. An advanced syncs output is provided, timed to the digital input, to synchronise the analogue
signal source to the digital data stream. The Inserter must be programmed with information about which
lines to insert the VBI data onto, this is done at the time of manufacture with the insertion table stored in an
EPROM. To change the setup the user can order ‘POD’, this is a small hand held programming device which
plugs into the rear of the unit. Option -FP provides a front panel to allow easy the setup and change of the inserter.
