A 16-channel H.264 PCI Express encoder can provide multiple output streams for each input video channel. With the Model 819 from Sensoray, this means two H.264 streams at independently set resolutions, frame rates and 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 analog 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 smartphones.

The H.264 encoders used on the Model 819 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. OEM quantity 2-9 pricing for the Model 819 is $785.
