Marseilles, France-based Nexvision has announced a network IP(Internet protocol) video camera design that incorporates the TexasInstruments (TI) DaVinci TMS320DM6467 processor. The Linux-basedCamHD hardware/software reference design is equipped with an AlteraCyclone III FPGA (field-programmable gate array), and boasts aclaimed 1080P HD resolution.

The Nexvision CamHD offers 30 frames per second (fps) HD videousing the H264-MP codec, claims Nexvision. It is said to supporteither full 1080P (2 megapixels at 30fps) or X-HD (5 megapixels at12fps, or 8 megapixels at 7fps). The CamHD also supports HDMIoutput and Power-over-Ethernet (PoE) operation.

Announced in December, TI's media-savvy TMS320DM6467 system-on-chip (SoC) combines a 297MHz ARM9 core with a 600MHzC64+ digital signal processor (DSP). The single-chip, 90nm-processSoC tunes core DaVinci DSP functions to the task of HD transcoding,says TI. For example, it can translate between video codecs, bitrates, and resolutions, as video is moved between different deviceson home media networks, TI claims.
