-config DVB_TTUSB_DEC
- tristate "Technotrend/Hauppauge USB DEC devices"
- depends on DVB_CORE && USB && INPUT && PCI
- select CRC32
- 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.
-
- This driver needs external firmware. Please use the commands
- "<kerneldir>/Documentation/dvb/get_dvb_firmware dec2000t",
- "<kerneldir>/Documentation/dvb/get_dvb_firmware dec2540t",
- "<kerneldir>/Documentation/dvb/get_dvb_firmware dec3000s",
- download/extract them, and then copy them to /usr/lib/hotplug/firmware
- or /lib/firmware (depending on configuration of firmware hotplug).
-
- Say Y if you own such a device and want to use it.
