Kworld ATSC-110 Antenna1/2 select

Hi all,

Back in Jan, 2007 a few threads appeared regarding the
2 RF input port of the Kworld ATSC-110 (e.g.,
https://www.redhat.com/mailman/private/video4linux-list/2007-January/msg00322.html)

I shared an interest in conveniently switching from
analogue TV input between either RF ports (along with
a few other interested parties).  I emailed Kworld and
a sympathetic techie send me a copy of the Philips
TUV1236D NIM data sheet.  With the help of this info,
I experimented with code changes which:

+ defined each RF port as separate inputs: Antenna1,
Antenna2 (in addition to the Composite and S-Video)
[in saa7134-cards.c];

+ set the appropriate bits in the I2C commands to the
TUV1236D to select the appropriate RF input when
setting the tuner to an analogue channel [in
tuner-simple.c].

The code changes seem to work OK with KDEtv and TVtime
- no detected problems.  The code, unfortunately, does
not select the RF input when ATSC is selected - the
existing code defaults to Antenna1 if 8VSB, i.e. a
digital channel, is being tuned.

Is anyone interested in the code?  If so, please let
me know how these changes may be integrated into the
v4l-dvb code repository.

Thanks.
