During digital overlay and output in SECAM standard, signals of color field synchronization are
being inserted into output stream according to GOST 7845-92 and OST 58-18-96, what allows
using board for trans-coding of signal from PAL to SECAM.
There is an option for capture and hardware based scaling of input video signal. It allows
resizing of pass-through signal along with overlaid graphics in real time. Ability to capture by
ALPHA Plus PCI-E board also allows deploying of chromo-key function.
Optional remote firmware update.
