Universal streaming IP Decoding board for the NPX3x00 Graphics Controller Series

The IP Streaming Video Decoder Board is the latest development for the eyevis NPX3x00 Series, it offers hardware decoding of universal streaming video signals in real-time with very low latency. Each streaming decoder card can decode up to 32 CIF streams or up to 8 D1 streams simultaneously. Through a new Hardware Decoding architecture each channel can simultaneously decode different codec formats. This flexibility allows large visualisation systems, supporting display grids of up to 64 outputs and a virtually unlimited number of inputs.

In the past, there were special decoding devices necessary, which were only able decode the streams from certain camera to process the signals from certain camera producers, or only certain stream formats. The NPX-IPDB can handle streams from any producer and any codec format, as soon as the codec is integrated. Each NPX-IPDB can decode various streams simultaneously, independent from the quality and codec format.
The main reason for the development of the NPX-IPDB was the rising demand for the integration of IP streams in large screen systems in control rooms. Transmitting video signals via IP networks is practically, and efficient, since the networks most often already exist.

With the NPX-IPDB the signals from the cameras and encoder can directly connected to the graphics controller of the large screen system.
The main advantage of the hardware decoder solution compared to software decoding, is that the performance of the system does not suffer from the decoding. With software decoding the processing of the signals affects the performance of the system’s CPU. With the NPX-IPDB the processing is done by the hardware of the board.

Decoding Overview:
The Decoder board is equipped with a powerful processor which can handle up to 8 streams with a resolution in D1 Quality and 25frames/s. Through the new hardware architecture also 32 streams in CIF quality are possible per decoder card. Megapixel Resolutions are supported as well.

One IPDB board can decode in real-time with 25/30 frames:

• 32x CIF 352x288
• 8x D1 720x567
• 2x Megapixel 1280x1024

Different codec formats can also be decoded simultaneously on the same decoder card, with no dependence on their resolution.
