From 3f3b48a0c6caba3b1a16a79d6a75a6ea4eac6b9c Mon Sep 17 00:00:00 2001 From: Abylay Ospan Date: Sat, 14 May 2016 00:08:40 -0300 Subject: [PATCH] [media] Change frontend allocation strategy for NetUP Universal DVB cards Old behaviour: frontend0 - DVB-S/S2 frontend1 - DVB-T/T2 frontend2 - DVB-C frontend3 - ISDB-T New behaviour (DVBv5 API compliant): frontend0 - DVB-S/S2 frontend1 - DVB-T/T2/C/ISDB-T DTV standard should be selected by DTV_DELIVERY_SYSTEM call.
