Lynx Technik yellobrik PVD 1800 3Gbit SDI Frame Synchronizer with Up/Down/Cross Converter

The PVD 1800 is engineered to address the challenges of synchronizing asynchronous SDI sources, utilizing robust “flywheel” algorithms to accommodate a wide variety of low-quality signals. It automatically extracts all 16 channels of embedded audio, delays them to match the video processing delay, and re-embeds them, maintaining audio-video synchronization. The module offers up to 30 frames of programmable output delay, adjustable in frames, lines, and pixels, providing precise control over timing. The integrated Up/Down/Cross converter allows conversion between 3G, HD, and SD video standards and features a selectable fast scale mode with less than 10 lines of delay. Additionally, the powerful Region of Interest (ROI) scaler enables users to extract a specific region of the incoming video and output it as a full-format SDI signal. The PVD 1800 is fully compatible with the yelloGUI software package, allowing for comprehensive configuration, control, and firmware updates via PC or Mac. :contentReference[oaicite:4]{index=4}
