Is there a program that will convert a display to NTSC format? And, what do PAL and NTSC stand for?

I believe there is a little PD program to flip the bit in the custom chip (that was set at powerup) and then reboot the machine. This only works if you have the new Agnus chip. Also, preferences under AmigaOS 2.0. If you want to conver the video signal after the fact, that takes a box called a standards converter costing $10000 to 30000 or so. >And, what do PAL and NTSC stand for? PAL = Phase Alternating Line. NTSC = National Television Standards Committee. = Never Twice Same Color :-) They actually refer to the color encoding system used for composite video as broadcast or recorded on a VTR in the relevant countries. Since Amigas don't have color composite output anymore, the only machines that should really be called "NTSC" or "PAL" are A1000s. But, since most folks use "NTSC" to mean 59.94/525/NTSC (the scan rate and color system used in the United States) and "PAL" to mean 50/625/PAL (the system used in many European contries), we'll go with the flow. For more info, tune into rec.video. Incidently, it is my understanding that both "PAL" and "SECAM" (the French color encoding scheme) are usually used with 50Hz vertical, 625-line transmission. Since Amigas don't do color encoding, doesn't this mean that we should call them PAL/SECAM amigas? To truly make them PAL or SECAM, doesn't one need the relevant encoder only, since the scan rates are the same? -------------------------------------------------------------------- Steve Tell tell@wsmail.cs.unc.edu CS Grad Student, UNC Chapel Hill.
