A PALplus picture starts as an anamorphic picture (to take advantage of the full line-count), then every 4th line gets dropped to restore the aspect ratio for non-palplus-devices. The dropped lines are transmitted hidden (don't know how they are hidden) in the black bars on the top and the bottom of the picture. A PALplus-decoder gets those hidden lines and reinserts them into the picture so that you end up with an anamorphic picture which can then be viewed as 16:9 with full line-count. To non-palplus-devices the picture looks like a normal 4:3 letterboxed picture (but it actually isn't) _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
