Convertors speed analogue video over IP

The iPort PT1000 ANL-2/12 and ANL-2/6 analogue video IP engines are billed as the industry's first analogue-to-IP convertors for applications requiring machine vision-grade performance.

The iPort PT1000 ANL-2/12 and ANL-2/6 analogue video IP (Internet protocol) engines are billed as the industry's first analogue-to-IP convertors for applications requiring machine vision-grade performance.

The PT1000 ANL-2/12 and ANL-2/6 engines use highly efficient FPGA (field-programmable gate array) technology to perform high-speed IP conversions on up to 12 multiplexed analogue video signals.

The signals are transported to PCs with low, predictable latency at up to 1Gbit/s (more than 100Mbyte/s) over standard GigE links or LANs (local-area networks).

From video source to PC memory, the engines typically achieve consistent latencies of less than 200us.

The iPort ANL-2/12 and ANL-2/6 engines are ideal for multiple-camera analogue vision systems.

They also integrate seamlessly in switched GigE vision networks with Pleora's PT1000-CL and PT1000-LV engines for Camera Link and LVDS (low-voltage differential signal) video.

These multiformat GigE vision networks lower the cost, extend the reach, and improve the efficiency of installations with more than one camera type.

"Our iPort ANL engines meet growing demand from vision system designers for communications platforms that combine performance with flexibility and low cost," said George Chamberlain, President, Pleora Technologies.

"The engines deliver the speed and latency needed for demanding applications, while offering the unmatched flexibility of multichannel communications over standard, affordable GigE equipment." Pleora's iPort PT1000 ANL-2/12 and ANL-2/6 analogue video IP engines accept all commonly used analogue video formats, including composite or S-video, NTSC and Pal, RS-170, CCIR, and Secam.

The engines simultaneously "frame-grab" and digitise two 30frame/s streams in any of these formats.

The PT1000 ANL-2/12, offered as an OEM board, supports up to six multiplexed channels per stream, for a total of 12 channels.

The PT1000 ANL-2/6, offered as a boxed unit, supports up to three multiplexed channels per stream, for a total of six channels.

Both engines also feature GPIO (general purpose input output) control, with two TTL (transistor-to-transistor logic) inputs and outputs, an RS232 serial port, and an optically isolated input and output.

Pleora's PT1000 ANL-2/12 and ANL-2/6 engines allow vision systems designers to build flexible multichannel vision applications using economical, widely available standard GigE switches and PC network interface cards or chips.

Separate PC framegrabbers are not required.

The engines allow designers to, for instance, interconnect multiple cameras, multicast data from one camera to multiple PCs, or distribute image processing across multiple PCs.

For security/surveillance applications, this highly scaleable, PC-based processing approach cost less and easier to manage than traditional DVR (digital video recorder) systems.

As part of Pleora's iPort vision connectivity solution, the PT1000 ANL-2/12 and ANL-2/6 engines are delivered with two powerful pieces of PC software: the iPort IP device driver and the iPort software development kit.

Running under Linux or Windows, this software streamlines video delivery and eases applications development.

And, as it supports Pleora's entire family of iPort IP engines, the software allows designers to build applications for multiple camera types using a single application platform.

The ANL-2/12 and ANL-2/6 are the latest members of Pleora's growing family of iPort IP Engines.

Pleora also offers lower-density ANL engines, and engines for Camera Link, LVDS and raw analogue or digital data.
