The Video Port Interface (VPIF) allows the capture and display of digital video streams. Features include:
• Up to 2 Video Capture Channels (Channel 0 and Channel 1)
– Two 8-bit Standard-Definition (SD) Video with embedded timing codes (BT.656)
– Single 16-bit High-Definition (HD) Video with embedded timing codes (BT.1120)
– Single Raw Video (8-/10-/12-bit)
• Up to 2 Video Display Channels (Channel 2 and Channel 3)
– Two 8-bit SD Video Display with embedded timing codes (BT.656)
– Single 16-bit HD Video Display with embedded timing codes (BT.1120)
The VPIF capture channel input data format is selectable based on the settings of the specific Channel
Control Register (Channels 0–3). The VPIF Raw Video data-bus width is selectable based on the settings
of the Channel 0 Control Register.
