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.

Composite Output (J3):

Thru connector BNC composite video signal is out.

S-Video Input (J2):

Thru connector miniDIN-4 video signal in S-Video (Y/C) format is in.

Composite Input (J3):

Thru connector BNC composite video signal is in.

YUV+Key/RGB+Key Output: (J6):

15-n pin connector D-SUB, which allows connecting VGA cable with BNC outputs Y/G, Cr/R, Cb/B

(green, red and blue, correspondingly) and Key signal (yellow).

During analog overlay, only computer’s graphics is being outputted thru 15-n pin connector. During

digital decoding/coding an output is identical to the main output.

Cable with additional connectors is not a part of a standard package and is being supplied separately.

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.

Main features

 Microchips with laser calibration of resistor’s matrixes;

 Relay with orthogonal prismatic contacts;

 Topology, what is used in valve/tube studio equipment and hi-end amplifiers;

 «Ground» bus is connected to «ground» of PC only in one point;

 Non trivial power supply;

 Full galvanic insulation from power train of PC;

 Physical and technological minimization of noise and interference.
