Features The VWI20 inserts VI (Video index) or WSS (wide screen signaling) into a SDI video signal. These VI and WSS values can then be used to pass on the right aspect ratio to other studio equipment, or to set top boxes (WSS only). With the VWI20 you can use presets to translate or adjust existing VI and WSS values and re-insert them in the video signal.

Main features are:

           

Auto detecting of 525/625 EDH processing Translate VI values into a WSS value.

Presets controllable through 8 local GPI contacts.

Analog output WSS insert, standard, extended, blank WSS and VI detection Transparent for embedded audio Locks to SDI input Full control and status monitoring through the front panel of the SFR04/SFR08/SFR18 and the Ethernet port (ACP) Optional 1 fiber input (replacing 1 SDI input) or 1 fiber output (replacing 1 SDI output) on I/O panel Optional 1 CVBS output (replacing 1 SDI output) on I/O panel

Applications The applications where a preset based VI/WSS inserter is used:

  

Insert VI or WSS values to control Aspect ratio converters or other equipment in studio environment.

Insert WSS for analog services or setup boxes to follow the correct aspect ratio.

Convert existing VI or WSS values in a video stream.
