I've decided to post some patches that attempt to bring some consistency across the ATSC demodulator drivers in the signal strength reporting mechanism.
If we use the lgdt330x driver as an example, signal strength is calculated as a percentage from SNR up to 35 dB. Why up to 35 dB? As indicated in the comments inside the drivers:
Calculate strength from SNR up to 35dB
Even though the SNR can go higher than 35dB,
there is some comfort factor in having a range of
strong signals that can show at 100%
The behavior of the code in this tree gives you a nice feeling of "100%" strong...
