3 Idea behind the dvb-usb-framework
11 #) **deprecated:** Newer DVB USB drivers should use the dvb-usb-v2 framework.
13 In March 2005 I got the new Twinhan USB2.0 DVB-T device. They provided specs
18 dibusb-driver would be a complete mess afterwards. So I decided to do it in a
19 different way: With the help of a dvb-usb-framework.
23 - Transport Stream URB handling in conjunction with dvb-demux-feed-control
25 - registering the device for the DVB-API
26 - registering an I2C-adapter if applicable
27 - remote-control/input-device handling
