Hello developers at convergence,

I am currently working on changes in the dvb module source to support
the analog module for the DVB-C cards.
I've collected all necessary documentation and got an idea how all the parts fit 
together.

Some simple functions like audio mixer settings and audio path routing within the 
MSP3403 chip are currently working.
Therefore I added an new AUDIO_DAC type into the av7110.c. So the SetVolume function 
work for DVB-C card with analog module.

But currently I have no idea how the analog TV functionality should be added to the 
ioctl interface. Can it be a part of the DVB-API? I think this is not the right place 
for it. But building a own video4linux device would prevent us from using DVB and 
analog TV at the same time.

The analog video output from the AD-converter saa7113 is connected to the port D1 B at 
the SAA7146. So I must switch the SAA7146 to another port, when someone wants to see 
analoge channels.

What do you think? What would be the better interface for userspace?


 Greeting Tim Lapawa
