As many know, getting standardized dvb signal info in linux has been a want for a very long time for a lot of users (and developers). There has been several talks/threads about it but nothing was ever merged. The subject has come up once again and Mauro has posted a patch for review. I know that there are at least a handful of coders here who have interest in this, including Klaus. I strongly urge anyone who would like to see this finally happen to take a few minutes and read the links below. Further, it would be great if people actively participated in the discussion so please post anything you may like to contribute to the discussion!
I have read the discussion. The kernel to userspace interface is not allowed to change, as this would brake userspace programs, so any fix would have to come from a new kernel side interface. Therefore at the VDR side we have two options: 1)Wait for the new kernel interface to happen with a standard way to report quality and strength. 2)Implement work arounds for each receiver. In my opinion this has to be done anyway, in order to let VDR run on old kernel versions.
