Sensoray, an OEM of video and industrial control products, has recently announced the availability of its Model 819 16-channel H.264 PCI Express encoder. The company's latest encoder can provide multiple output streams: two H.264 streams at independently set resolutions, frame rates, bitrates; a low frame rate JPEG stream and an uncompressed (preview) stream.

Each channel allows an individually configured multi-window character and graphics overlay and provides real-time motion data.

An internal 16 X 4 analogue crosspoint video switch is used to route any combination of four composite output channels to external video monitors. Individual scalers and deinterlacers facilitate optimal resolutions for each captured stream.

For example, a high-resolution, high bitrate stream may be selected for archiving, while a lower resolution, low bitrate stream is preferable for simultaneous streaming to handheld devices, including smart phones.

The H.264 encoders implement high quality Baseline Profile Level 3 compatible H.264 compression. Flexible encoder control allows achieving optimal stream parameters for a wide variety of applications.

The output streams may be formatted as elementary, MPEG-4 or transport stream. Sensoray provides an SDK for the Model 819 that includes drivers and demo applications for both Windows and Linux operating systems.
