Model 819 | 16-Channel H.264 Encoder with 16x4 Crosspoint Switch
- 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 16 video inputs.
The 819 can provide multiple output streams for each input video channel: two H.264 streams at independently set 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.
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.
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).
Model 609TC provides sixteen BNCs for camera connections and is 2U height
Model 609TE provides sixteen BNCs for camera connections and fits in the space of a PC's CD player
Model 609TG supports thirty-two camera connections and is 2U height for 19" enclosure
