From 4caba4261f2649215710ac0298bd7814080000ad Mon Sep 17 00:00:00 2001 From: Oliver Endriss Date: Fri, 17 Mar 2006 05:29:15 -0300 Subject: [PATCH] V4L/DVB (3533): Add WSS (wide screen signalling) module parameters Add wss_cfg_4_3 and wss_cfg_16_9 configuration options. Firmware 2623 or later required. Both parameters are bit masks: - bit 15: disable WSS - bit 14: send short WSS burst, then turn off WSS - bit 13..0: WSS bits as specified by the standard These parameters are useful if you own a broken tv set which does not handle wss correctly. Default settings: - wss_cfg_4_3: 0x4008 - wss_cfg_16_9: 0x0007 These should work with most devices.
