Changes

On systems connected with a composite, s-video or rf cable the color of the video signal is encoded using either NTSC or PAL. While NTSC and PAL has become synonymous with 60 and 50hz, the color encoding is independent of refresh rate, with the Dreamcast popularising "PAL-60" modes in PAL regions. Note that a RGB or component video signal is not inherently NTSC or PAL coded. When playing on an emulator, [[NTSC filters]] can be used to produce an image similar to playing on a TV.  SECAM was is a third color standard but due to the majority many of countries using that used it being behind the iron curtain, were [[wikipedia:Second World|Second World]] and [[wikipedia:Third World|Third World]] few consoles would use that format, and consoles and home computers released in France would often use RGB SCART cables instead.See this [[wikipedia:SECAM#Countries_and_territories_that_use_SECAM|Wikipedia article]] for a list of current and former SECAM countries
