16-channel H.264 encoder with 16x4 crosspoint switch | Model 819

Model 819 16-channel H.264 encoder with 16x4 crosspoint switchView CE compliance report
  • 16 channel H.264 full frame-rate capture
  • Two simultaneous H.264 streams per channel
  • 16x4 video crosspoint switch
  • PCI Express x1 interface
  • HTTP live stream segmenter


Model 819 is a multifunctional video codec capable of simultaneous capture from sixteen video inputs. The board can provide multiple output streams for each video input: two H.264 streams at independent resolutions, frame rates, bitrates; and an uncompressed (preview) stream. Each channel allows an individually configured multi-window character and graphics overlay and provides real-time motion data.

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, smart phones.

H.264 Encoder

The H.264 encoders implement efficient 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 or MPEG-4 program (.mp4) streams.

Model 819 Sample Streaming Application



A termination box is recommended for interfacing video signals to the 819, along with a cable, model 817C1 (DB37 to IDC34), to connect the 819 to the termination box. Sensoray offers the following termination boxes:

Model 817TAS is an indispensable tool for application development and troubleshooting with Sensoray's 16-channel frame grabbers (models 615, 617, 817, and 819). The 817TAS splits a standard composite TV video signal (BNC connector) into 16 buffered outputs of standard amplitude and impedance. The outputs are connected to a 34-pin ribbon cable connector that is compatible with all of the above-mentioned frame grabbers. A combination of models 817TAS, 609TC/TE/TG and 817C1 cable yields a splitter with 16 BNC outputs.

Model 609TA-ND provides sixteen BNCs for inputs and eight BNCs for video output; also requires cable 609C2 (video out).
