From 682ce8fad34b8959b55ecd597934732e68453c6d Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 23 Mar 2008 22:43:22 +0000 Subject: cx88: Enable chroma AGC by default for all non-SECAM modes From: Frej Drejhammar An enabled chroma AGC will not degrade picture quality if enabled on a color PAL or NTSC signal with nominal signal levels. It will give a significant color reproduction improvement if the chroma signals diverge from nominal levels. Therefore enable chroma AGC by default for PAL and NTSC standards.
