From 2cf846b1f3006b88b7f381082b23ba25030a1650 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 15 Sep 2020 09:18:32 +0200 Subject: [PATCH] media: vidtv.rst: update it to better describe the frequencies The virtual driver has now a minimal set of frequencies for a single transponder to be found by each DVB standard. Document it, and update related information about the simulated LNBf.
