TIGARD, Ore., 4 Oct. 2013. Sensoray in Tigard, Ore., is introducing the model 2224 USB H.264 embedded computing video and audio encoder for broadcast-quality, high-profile video-processing for DVR, NVR, and streaming server applications.

The board products board offers full screen text and graphics overlay and one SDI input that supports a variety of video resolutions, including 1080p/1080i, 720p, and 480i/576i. The board also has overlay generators, HD and SD frame grabber, and live preview stream.

It has graphics enhancements that enable capture of an HDTV signal from an HD or SD-SDI source and formats it for display and image compression. Its high-speed hardware can generate on the fly, scale and display text and graphics from standard BMP files, which allows graphics to be easily and quickly placed and moved anywhere on the screen.

The board can send an uncompressed, down-scaled video stream over USB to enable low-latency video previewing on the host computer with minimal CPU overhead. The uncompressed preview stream can flow over USB to enable low-latency video previewing on the host computer with minimal CPU overhead. The uncompressed preview stream can flow over USB concurrently with the H.264 transport stream and a captured snapshot.

The model 2224 provides three different audio input options?stereo and mono line-in audio input, XLR3 microphone input, and SDI embedded-in audio. The board employs special hardware and advanced techniques to keep audio synchronized to video, thereby eliminating the lip sync errors.

Sensoray provides a software developers kit (SDK) for the model 2224 that includes drivers, programming examples and documentation for both Windows and Linux operating systems. The software demonstrates the capabilities of the model 2224, including digital video recording, real-time image display, single image storage and display, real-time H.264 encoding, and stored file playback.
