2013-08-23[media] cx231xx: Add support for KWorld UB445-UJohannes Erdfelt
The KWorld UB445-U is similar to the UB430-AF but with a Samsung S5H1411 frontend. Luckily all of the hardware is already well supported, just the device and USB ids need to be added to get it to work.

2013-03-04[media] cx231xx: Improve signal reception for PV SBTVDMauro Carvalho Chehab
Instead of using 3.3 MHz IF, use 4MHz. That's the standard value for the demod, and, while it can be adjusted, 3.3 MHz is out of the recommended range. So, let's stick with the default. With regards to the IF voltage level, instead of using 0.5 V(p-p) for IF, use 2V, giving a 12dB gain. The rationale is that, on PixelView SBTVD Hybrid, even 2V(p-p) would be in the nominal range for IF, as the maximum range on this particular device is 3V. A higher gain here should help to improve reception under weak signals. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
