PRODUCT OVERVIEW

Product Overview

Four Independent CVBS Inputs for Analog Video Digitization

The card integrates four independent BNC CVBS inputs for PAL and NTSC analog video, with YUY2, XRGB and NV12 output formats. On-board processing supports scaling, aspect-ratio conversion, frame-rate conversion and multiple capture streams. DirectShow, DirectKS and supported V4L2 drivers simplify application and SDK integration.

All four BNC connectors operate as independent CVBS video inputs
PAL input at 720×576 50i and NTSC input at 720×480 60i
Maximum processed output up to 50 fps for PAL and 60 fps for NTSC
No audio capture and no CVBS video loop-through outputs

Specification Note：The four BNC connectors are independent CVBS inputs. The incoming signal is conventional interlaced PAL 720×576 50i or NTSC 720×480 60i; the stated 50/60 fps values are the maximum processed capture-output frame rates. Actual multi-channel performance depends on the input standard, host platform, PCIe slot, driver and application. Audio capture and video loop-through are not provided.
