    Description

    Model 2231 is an ultra-compact, USB-compatible analog HD video capture device optimized for embedding in OEM systems. It captures analog HD video (AHD, HD-TVI, HD-CVI) at resolutions up to 1080p30, reformats the video and adjusts the frame rate as desired, adds user-defined overlays, compresses it to H.264 or MJPEG, and transmits it over USB. At the same time, it will simultaneously generate and transmit a low-latency uncompressed preview video stream.

    Audio can be captured from the microphone or line source inputs. Audio may be sent uncompressed, or it may be compressed and multiplexed into a transport stream along with compressed video, or both simultaneously.

    Video processors

    Dual video processors and compression engines allow the video to be copied and simultaneously processed as two independent streams. Video processing functions include image resizing and mirroring, frame rate decimation, and overlaying qualified regions with graphics and text. This dual-stream capability is essential in many applications, such as when a high quality stream is required for recording while another stream of lower resolution, bit rate, or both, is needed for mobile device viewing or transmission over bandwidth-limited networks.

    Stream formats

    Each compression engine independently performs MJPEG or efficient, high-profile H.264 video compression. In the latter case, audio is compressed to AAC-LC and the stream multiplexer outputs MPEG transport stream (MPEG-TS) format. The multiplexer employs precise hardware timestamps to ensure perfect audio-video sync on players.

    Software

    The unit is a fully compliant USB Video Class (UVC) device that works with any standard UVC driver, thus eliminating the need for a custom driver and allowing seamless control through video APIs such as DirectShow and Video4Linux.

    Free Linux and Windows software development kits (SDKs) are available for model 2231. The SDKs include a high-performance API with popular functions such as video snapshot, recording to files (in AVI, MP4 and TS formats), overlay management and, to facilitate styled text, functions for drawing Unicode text on video overlays. Also included is a comprehensive demo program that shows off the device's full capabilities, complete with source code that serves as an ideal starting point for custom applications.
