KWorld ATSC 110

The KWorld ATSC 110 is an ATSC PCI card, and is supported under Linux (added to kernel 2.6.17). It supports 8VSB (antenna) reception of ATSC signals, but not QAM (cable).

This card requires a firmware file (dvb-fe-nxt2004.fw¹) for the demodulator, which can be obtained using the get_dvb_firmware perl script included in the kernel sources:

# cd /[kernel source directory]/Documentation/dvb/
# perl get_dvb_firmware nxt2004

Once the download is complete, place a copy of the firmware file in your /lib/firmware directory. (This directory may differ with some distros; consult your distro's documentation for the appropriate location).

Note 1: All devices that use the Nxt2004 demodulator are currently using a firmware version from the AVerTVHD MCE A180.
