Asynchronous data input
Advanced sync reference output

The VDB Data Bridge is designed to provide a cost effective solution to several system integration problems involving data signals carried on VBI lines. The Data Bridge has two inputs, the digital program input and a data input. The data input is either digital or analogue or both may be fitted. An internal buffer stores the VBI data allowing it to insert data from non - synchronous sources. With the Data Bridge it is possible to take VBI data from one digital stream and insert it into another, copy VBI data between SDV streams, swap data between different lines in the VBI or insert ITS signals. The VBI data is stored in the buffer as a video signal and is not decoded or regenerated allowing the Data Bridge to be used with any type of VBI signal. Line selection can be controlled from an integral from panel, or may be programmed in an EPROM. An optional analogue PAL/NTSC ouput is available for monitoring purposes.
