ANALOG VIDEO CAPTURE SERIES
Internal CVBS / S-Video Capture Card Series
Two internal solutions for analog video ingest, legacy-device digitization, and professional system integration: a four-channel CVBS card for concentrated capture and a single-channel card with selectable CVBS or S-Video input. Both products emphasize on-board hardware deinterlacing for smooth PAL and NTSC capture in preview, recording, analytics, and custom applications.

SHARED ADVANTAGES
Designed for upgrading legacy analog video systems
Hardware DeinterlacingOn-board processing converts PAL/NTSC interlaced video and reduces combing artifacts in moving scenes while lowering host-side processing demand.
50 / 60 fps CaptureUp to 50 fps for PAL and 59.94/60 fps for NTSC supports smooth preview, recording, and motion analysis.
Internal PCI Express DesignInstall directly in a workstation, server, or industrial PC to reduce external devices and simplify long-term system integration.
Professional Software WorkflowsSuitable for video preview, recording, digitization, analytics, and OEM / ODM integration.

HARDWARE DEINTERLACING AND FRAME RATE
Smooth progressive capture across both products
PAL and NTSC analog video use interlaced scanning. Hardware deinterlacing converts video fields into progressive images, reducing combing artifacts and providing smooth capture at up to 50/60 fps.
PAL · 720 × 57650i input (25 frames / 50 fields per second); up to 50 fps after hardware deinterlacing.
NTSC · 720 × 48060i input (approximately 29.97 frames / 59.94 fields per second); up to 59.94/60 fps after hardware deinterlacing.
SELECTION GUIDE
Choose according to the system requirement
01 · CHANNEL COUNTCount the video sourcesChoose the four-channel card for four CVBS sources, or the single-channel card for one source.
02 · INPUT INTERFACECheck the signal connectorChoose by channel count for BNC CVBS; select the single-channel CVBS / S-Video card when S-Video is required.
03 · AUDIO REQUIREMENTCheck synchronized audioSelect the single-channel card with Line In when synchronized stereo audio is required.
04 · SOFTWARE / PLATFORMConfirm the final configurationVerify the required operating system, driver, pixel format, and application support for the selected product.

Specification note: The 50/60 fps figures refer to progressive capture after hardware deinterlacing: up to 50 fps for PAL and 59.94/60 fps for NTSC. On the single-channel product, CVBS and S-Video share one capture channel and cannot be captured as two simultaneous sources. Audio, pixel-format, operating-system, driver, and SDK support may vary by hardware and software version; refer to the applicable datasheet and final confirmed specifications.
