[linux-dvb] Help for developing a driver for a usb ISDB-T

[Bruno Seabra Lima]

Hi,
I'm a master student in brazil. My work is related to digital tv and i wanna
help developer a driver for a USB card ISBD-T.
I already seen the DVB API 5.1 that has a support for ISBD-T. I just wanna
know a minimal guideline of the things i have to do.
Things like Do i have to make a new frontend ? How do i use the new
parameters for ISDB-T ?
I open the device and found a very curious thing:

We have two chips, the first one is:
DIB8076MC (STK807x), i guess this is the tuner.
the second one is:
0700C, i guess this is the usb bridge.
For what i saw from the linuxtv wiki, the 0700C is support by others
drivers.
I search the DiBCOM site and found that the DIB8076MC is pin-to-pin
compatible with the 7070p (that is support by other drivers).

Below i have the lsusb -v.
