Surveillance DVR reference design runs Linux

“Fabless semiconductor firm Conexant and Taiwan-based
system-on-chip (SoC) design company Grain Media announced a
Linux-based hardware/software platform for video, image processing,
and surveillance applications. Intended for creation of 16-channel
digital video recorders (DVRs), the reference design combines
Conexant’s CX25838 multichannel video decoders and Grain Media’s
ARM-based GM8186/GM8187 SoC, which specializes in H.264
compression.

“The jointly developed reference design targets the development
of video surveillance DVRs that support 16-channel encoding,
recording and playback, as well as providing dual- or
triple-display output, according to Conexant (which appears to be
the primary vendor for the design).

“Key features include support for embedded keypad and remote
controller functionality, “without the need for an external
micro-controller,” says Newport Beach, Calif. based Conexant. The
design also offers “a single crystal for full system operation,”
says the company.”
