Comment 11 for bug 284405

The extraction script actually is in the linux source tree (Documentation/dvb/get_dvb_firmware). The following firmware files are directly fetched from http://www.linuxtv.org/downloads/firmware (which has no license information):

dvb-ttpci-01.fw
dvb-dibusb-5.0.0.11.fw
dvb-fe-or51211.fw
dvb-fe-or51132-qam.fw
dvb-fe-or51132-vsb.fw
dvb-usb-bluebird-01.fw

The following firmware files are also on linuxtv.org but not coded into the script:

dvb-usb-avertv-a800-02.fw
dvb-usb-dibusb-6.0.0.8.fw
dvb-usb-dtt200u-01.fw
dvb-usb-umt-010-02.fw
dvb-usb-vp702x-01.fw
dvb-usb-vp7045-01.fw
dvb-usb-wt220u-02.fw

The one mentioned above has a different source here:
