VDCP Connection to Automation System
FAB Media Encoder can be used as a remotely controlled video disk recorder.
The VDCP (Video Disk Control Protocol) protocol is supported on the serial
port.
This enables you to connect FAB Media Encoder to the automation system (i.e.
Louth) and control recording/encoding of media files with a media gathering
station that is used to record programmes into the automation system. In case of
Louth Automation System the Media Client can be used to control the Media
Encoder remotely.
The VDCP protocol requires an RS422 interface. To connect FAB Media
Encoder to the automation system use a RS232 <-> RS422 converter and
connect the Media Encoder’s COM port to the RS422 port of the automation
system. In addition the COM port has to be enabled for VDCP in the Media
Encoder settings that you will find in Options/Setup.
FAB Media Encoder does not replace a Video Disk Recorder/Player because it
does not have a video output. If the automation system will instruct FAB Media
Encoder to playout a recorded file FAB Media Encoder will simply not do
anything because there is no video output.
FAB Media Encoder may start and stop encoding with a short delay after it was
instructed to do so by the automation system. This however is not important for
the application because the file will never be played out frame accurately by the
automation system. The timecode in the encoded Media file will however always
be encoded frame accurately even if the encoding started with a short delay.
