The PureVu CNW22XX family of micro-mezzanine modules is specifically optimized for low latency HD/SD industrial video applications. Examples are electronic newsgathering (ENG), surveillance, tele-robotics, telemedicine and industrial imaging.

The PureVu CNW22XX micro-mezzanine modules encode 1920x1088 or 1280x720 HD video in H.264 format. Stereo audio input is encoded in PCM format. Audio and video PES are multiplexed into a DVB MPEG-2 Transport Stream, compliant with the ISO/IEC 13818-1 standard. DVB support includes 188 and 204 byte packet formats and DVB service information in compliance with ETSI EN 300 468.

The PureVu CNW22XX micro-mezzanine modules de-multiplex a DVB MPEG-2 TS into separate PCM encoded audio PES and H.264 encoded video PES. The audio and video streams are decoded for playback and display.

Cavium’s Super Low Latency TechnologyTM or SLL TechnologyTM guarantees sub frame-rate encode-decode latencies, the lowest in the industry.

The 8-bit TS interface on the encoder and the decoder modules allows for either DVB-ASI or DVB-SPI I/O. Other interfaces present on the modules include a SPI and a UART interface. These can be used for an external host processor to control, configure and monitor the modules.
