The LT-312D is a HDMI 2.0 4K/UHD video capture and frame grabber board for PCI express based desktop and embedded systems. It is primarily designed for video recording, image capture, and video streaming applications where robustness, reliability and long-term availability are critical. The LT-312D is typically used in high-performance medical, laboratory, industrial, and aerospace systems.

Capable of acquiring uncompressed video signals with resolutions and frame rates up to 4K (4096 x 2160) at 60 frames per second with zero frame drops under all normal operating conditions. The LT-312D achieves this through smart hardware frame buffering, high bandwidth processing and a four lane PCI express Gen.2 bus.

All standard HD, UHD and 4K video formats are supported from 720p to 4K DCI. Optionally, non-standard and special resolutions can be supported as well.

There is also a multi-channel HDMI acquisition mode where up to two different video signals can be captured simultaneously. In this mode the signals are limited to 4Kp30 or below. Each of the inputs can be of the same format or have different resolutions and frame rates.

An extensive set of software tools are available to assist in the evaluation, use, and customer integration of the LT-312D support. An easy-to-use API along with numerous examples with source code are provided. Support for DirectShow, ffmeg, Video4Linux, .NET, c++, c#, Python, etc., simplify product development and integration into existing applications.

Video Processing Diagram

The LT-312D is comprised of several functional elements as shown in the diagram above, the video multiplexing and video acquisition blocks are the responsables of detecting the type of video input (resolution, frame rate …) and of sending this information together with the video data to the acquisition buffer.

From there the video data can be send directly to the Host PC through the PCIe Bus Interface or additional video processing such a hardware deinterlacing, color adjustments, video scaling can be done before transmiting to the Host PC
