From d42f1cb25334bbcddf213a00bb67083414027933 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sat, 9 Mar 2013 19:26:28 -0300 Subject: [PATCH] [media] siano: Convert it to report DVBv5 stats While this frontend provides a nice set of statistics, the way it is currently reported to userspace is poor. Worse than that, instead of using quality indicators that range from 0 to 65535, as expected by userspace, most indicators range from 0 to 100. Improve it by using DVBv5 statistics API. The legacy indicators are still reported using the very same old way, but they're now using a proper range (0 to 65535 for quality indicadors; 0.1 dB for SNR).
