AlphaSDI HD – board for generation and overlay of computer graphics
onto pass-through signal
AlphaSDI HD could be implemented for development of computer systems for graphics design for real
time TV-air (CG-систем) and broadcast video servers.
Main features
Works with 8 and 10 –bit sequential component signal 3G-SDI, HD-SDI, SD-SDI, DVB-ASI
according to recommendations ITU-R.601, SMPTE 424M, SMPTE 292M, SMPTE 274M,
SMPTE 259M and DVB-ASI;
Automatic turn on of relay based BYPASS for video signal after PC’s shut down;
Synchronization, using input SD/HD/3G-SDI signal or analog Black burst/tri-level. In lieu of
external synchronization internal synchronal generator is used.
Optional sending of output to HDMI v.1.3; or to preview;
Alpha-channel in digital format is provided for work with external mixer with DSK (Down
Stream Key). Delay of alpha-channel with respect to outgoing graphics is controlled
programmatically in a wide range;
Option for simultaneous capture of incoming 3G-SDI, HD-SDI, SD-SDI, DVB-ASI video
signals, and with result of internal mixing with incoming signal;
Possibility for capture of audio stream, extracted from incoming video signal;
Support of 16-channel audio, embedded into SD/HD/3G-SDI stream. Possibility for insertion of
new packets of audio, replacement and transmission of existing packets;
