SDI, HDMI and Analog Video Connectivity

The OEM-LHi combines multiple video connection types on one PCIe card, helping developers and system designers connect professional video equipment to computer-based applications. Its interfaces include 3G-SDI, HD-SDI, SD-SDI, HDMI, and analog component video, along with SD composite and S-Video support.

This range of connections makes the card useful for broadcast systems, video processing applications, capture and playback workflows, and custom production solutions that need to work with both analog and digital equipment.

Hardware-Based 10-Bit Up, Down and Cross-Conversion

The OEM-LHi includes hardware-based 10-bit conversion for supported SD and HD video workflows. It can perform up-conversion, down-conversion, and cross-conversion on supported inputs or outputs, helping systems work with different SD and HD formats.

This conversion capability is separate from the card's support for 3G-SDI, HD-SDI, and SD-SDI connectivity.

12-Bit Analog Video and HDMI Deep Color

For analog workflows, the OEM-LHi supports 12-bit HD component video I/O and 12-bit SD component, composite, and S-Video I/O. Its HDMI v1.3a interface supports Deep Color at up to 30 bits per pixel for compatible equipment, including 10-bit displays.

These options help bridge analog video sources and professional digital video systems while supporting a range of monitoring and processing applications.

Professional Audio, Reference and Machine Control

The OEM-LHi supports multiple audio formats and synchronization options for professional production systems:

• AES digital audio: Two-channel balanced XLR input and output, 24-bit at 48 kHz
• Analog audio: Two-channel balanced XLR input and output, 24-bit at 48 kHz
• Embedded SDI audio: Eight-channel input and output, 20-bit at 48 kHz
• Synchronization: Selectable HD/SD genlock, LTC, or reference video input
• Machine control: RS-422 9-pin port

These connections support integration into workflows requiring synchronized video, professional audio, and external device control.

Windows and Linux SDK Support

The AJA OEM-LHi is designed for integration into custom software and hardware systems through AJA's Software Development Kit (SDK). The SDK uses a common application programming interface (API) across supported platforms, helping developers build applications for compatible AJA cards and operating systems.

The supplied product information lists Windows Vista 32-bit and 64-bit, Windows XP 32-bit and 64-bit, and Linux 32-bit and 64-bit support. These are legacy operating systems, so verify SDK availability, driver compatibility, and system requirements before purchasing for a current computer.
