How can the DVB-T signal bandwidth be larger than what the 'dtv' receiver is capable of if that device was actually originally designed to receive exactly that class of signal?
The 2.8 MHz limitation comes from shipping raw RF samples off the device over USB 2. When operating as a DVB-T receiver the device decodes the signals before sending them over USB so it uses less bandwidth.
The device was originally intended only as a dtv receiver and not a general purpose software defined radio. The hobbyist/ hacker community discovered the hidden debug mode that allows raw data acquisition and wrote drivers for it.
