Description

Model 617 combines the functions of a 16x4 video crosspoint switch, a frame grabber, hardware JPEG compression and digital I/O into one PCI board. The 617 accepts sixteen composite video inputs and routes any four of them to separate video decoders for digitizing. The use of four decoders eliminates losing frames during channel switching. At least two decoders are always in sync and ready for the JPEG compression circuit.

The 617 uses multiple frame buffers to interlace full size images before they are compressed. This allows the 617 to generate just one compressed image per frame instead of two per interlaced frame.

Frame rates

Each of the four decoders digitizes 30 frames per second to give an overall board throughput of 30 fps for 640x480 interlaced frames, including JPEG compression. If all sixteen channels are used, the frame rate per channel is 1.8 fps.

Hardware compression

Model 617 executes hardware JPEG compression to greatly reduce the amount of memory needed to store images. Hardware compression reduces the CPU and PCI bus loading.

Multiple boards

Sensoray's software supports multiple 617s in the same PCI bus. For example, two 617s may be used to expand the number of video inputs to thirty two. If sixteen inputs are distributed between two boards the overall capture rate increases to 3.7 fps per channel.

Real-time outputs

Any four of the sixteen inputs may be routed to four output channels for display on video monitors. A software-selectable switch after each buffer amplifier allows multiple 617s to share the same video monitor.

Input clamping

Each input channel has a clamping circuit to minimize the effects of switching from one floating camera signal to another. Image artifacts from a previous channel will not affect the current channel.

Text caption buffer

Model 617's caption buffer allows overlaying text on each frame. The text is within a transparent box that may be positioned anywhere within the frame. The text size and color are programmable.

Special output

The 617 also supplies small-size uncompressed frames suitable for motion detection by the host computer. These are 128x96 pixels or 256x192.

Model 617-4, 4 channel output

Model 617-4 is a lower-cost version of the model 617 with just four video inputs, four real-time video outputs, and 16 digital I/O signals. Video inputs are connected directly to BNCs located on the board's hold-down bracket. The 617-4 has a faster frame capture rate than the 617.

The overall board throughput is 120 fps for 320x240 size frames, 60 fps for 640x240 size frames, and 30 fps for 640x480 interlaced frames.

Model 817TA distribution amplifier

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

Termination boxes

A termination box is recommended for interfacing the video signal to the Model 617. A flat cable, Model 609C1 (video in) is needed.
