The MPEG-TS (DVB) and TV-IN (Analog) subsystems are completely separate, not sharing anything other than being in the same SoC package. As far as I'm aware, no viable driver exists for either part, no documentation exists and nobody is working on either of them at the moment. There is quite a bit of documentation on the MPEG-TS part. And some people have been looking into writing a driver, but lack of commonly available hardware to develop on slows things down. The TV-IN part do not have any documentation that I know of. Even missing from most hardware pinout documents. Not sure if I have seen any binary Allwinner drivers for either, even less any source code. If you must have TV input now, I recommend getting a USB TV decoder. Yes. That is undoubtedly the fastest path to get something running. The MPEG-TS and TV-IN options is very interesting if you are building a TV box using Allwinner CPU. In which case you probably have a support contact at Allwinner to ask, but might also be bound by NDA agreements and not able to do anything..
