From 092502207af0ea4f41035bff5672a29f83ee0904 Mon Sep 17 00:00:00 2001 From: Oliver Endriss Date: Fri, 17 Mar 2006 09:29:15 +0100 Subject: Add WSS (wide screen signalling) module parameters From: Oliver Endriss 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.
