HD/SD USB audio/video encoder supports both analog and digital input formats
New devices enable video capture from various HD and SD sources, including DVI and component.
Sensoray (Tigard, OR) has announced an addition to its extensive line of high-quality broadcast grade, low-latency and real-time video products. The Sensoray Model 2263S is a versatile USB audio/video encoder supporting multiple analog and digital input formats. The device captures HD or SD video and simultaneously sends a compressed and an uncompressed (preview) stream to the host.
Supported video inputs include DVI, component (with a component to DVI-I adapter, not included) and composite. Audio is optionally captured from analog line input, compressed and multiplexed into transport stream. The company says the device is well-suited for "uncompromising capture of multiple video sources, such as video pipeline inspection, radar and sonar processing, remote video surveillance and traffic monitoring."
Model 2263S is designed as a UVC (USB Video Class) device, which means it does not require a device-specific driver. It is controlled using a video API (DirectShow or Video4Linux). Sensoray provides Software Development Kits (SDK that speed up application development) for several operating systems. A fully functional demo application illustrates the Model 2263S's capabilities and serves as a good starting point for custom development, notes the company.
In terms of stream format, the device implements efficient H.264 video compression. The resulting data is output as an MPEG transport stream (MPEG-TS), or in MP4 or AVI file formats. Audio compression is performed using AAC-LC. High precision hardware timestamps used for multiplexing aid in keeping audio and video data in sync. MJPEG compression is supported for snapshots and AVI streams.
