config DVB_TTUSB_DEC tristate "Technotrend/Hauppauge USB DEC devices" depends on DVB_CORE && USB && FW_LOADER help Support for external USB adapters designed by Technotrend and produced by Hauppauge, shipped under the brand name 'DEC2000-t' and 'DEC3000-s'. Even if these devices have a MPEG decoder built in, they transmit only compressed MPEG data over the USB bus, so you need an external software decoder to watch TV on your computer. The DEC devices require firmware in order to boot into a mode in which they are slaves to the PC. See linux/Documentation/dvb/FIRMWARE for details. The firmware can be obtained and put into the default locations as follows: wget http://hauppauge.lightpath.net/de/dec215a.exe unzip -j dec215a.exe Software/Oem/STB/App/Boot/STB_PC_T.bin mv STB_PC_T.bin /usr/lib/hotplug/firmware/dec2000t.bin unzip -j dec215a.exe Software/Oem/STB/App/Boot/STB_PC_S.bin mv STB_PC_S.bin /usr/lib/hotplug/firmware/dec3000s.bin Say Y if you own such a device and want to use it.
