NAME

cxm -- Conexant iTVC MPEG Coder

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file: device iicbus device iic device iicbb device cxm

DESCRIPTION

The cxm driver provides support for the PCI video capture on the Haup- pauge PVR-250/350. It uses the bktr(4) and Meteor driver ioctls. Note that in order for the cxm(4) driver to work properly, the necessary firmware files have to be extracted from the driver CD-ROM prior to com- piling the kernel. The tool necessary to do this can be found in /usr/src/tools/multimedia/cxm/extract_fw.
