Alpha Plus PCI-E - card for graphics generation and overlay for pass-
through analog video signal
Stream Alpha Plus PCI-E could be implemented in PC based systems for real time graphics design
during broadcast (CG-system) and broadcasting video servers. The board can be used for overlays for
composite and/or S-Video signals in PAL, SECAM, NTSC standards.
Main features
Automatic turn on of relay for video signal BYPASS after PC’s shut down.
Output of component YUV and alpha channel signal allows using card for work with mixer,
which has corresponding DSK-input (Down Stream Key).
During overlay in analog mode the pass-through signal does not get decoded, bur goes thru the
board without alterations, preserving frequency mode and service information.
During overlay in digital mode signal gets decoded using color combine filter for separation of
signals, responsible for brightness and color.
During overlay in digital mode it is possible to use combination of input and output signals in
different signal formats. It allows, for instance, to lower requirements for quality of input signal,
preserving high quality of output one.
All output signals are processed with filters and measured up to the level of black. Green signal
of component output and alpha-channel have built-in video synchronization, which could be
turned off.

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.

Sound Pro – extension audio card
This board is installed inside PC and connects either to video card or Stream Alpha Plus PCI-E or
AlphaSDI HD using special ribbon cable for transmission of audio stream and control signals. Board
provides professional quality audio track, synchronized with video. It grants precise insertion of audio
in pass-through audio stream. Also, this board has capability for analog and digital mixing of pass-
through audio streams and provides Audio BYPASS after shut down of PC.
