Stream Alpha Plus

Alpha plus connectors

• Works with pass-through composite or S-Video signal of PAL, SECAM and NTSC standards. Automatic activation of video signal relay bypass mode upon computer power loss.
• YUV component and key (alpha-channel) signal outputs allow to use the card with a mixer that has component and DSK (Down Stream Key) inputs.
• In analog mixing mode pass-through signal is not being decoded, it is carried through the card without changes, while saving all its frequency characteristics and service information.
• In digital mixing mode the signal is decoded by the latest PHILIPS decoder with color combine filter for dividing brightness and saturation signals.
• In digital mixing mode the number of connection combinations is unlimited. This lowers the requirements for input signal quality, while preserving the high quality of the output signal.
• All output signals pass through active filtration and black balance anchor. Component output Green signal and key signal (alpha-channel) have built-in video synchronization with disabling option.
• Capture and hardware scaling of video signal from card input allow to resize the pass-through video stream image in real time in combination with computer graphics overlay.
