The PVD 1800 is a broadcast quality compact SDI frame synchronizer with highquality Up/Down/Cross converter and scaler for professional applications in theBroadcast, Post Production and Pro A/V industry. The frame synchronizer utilizes robust “flywheel” algorithms that will accommodate a wide variety of low quality asynchronous SDI sources. All embedded audio is extracted and delayed automatically to match the video processing delay. The module also provides up to 30 frames of programmable output delay, adjustable in frames, lines and pixels. The Up/Down/Cross converter can convert between 3G/HD/SD video standards and has a selectable fast scale mode (<10 lines delay). In addition, the converter has a powerful Region of Interest (ROI) scaler that allows the user to extract a specific region of the incoming video and to output this as a full format SDI output.
