During the [[First_and_second_generations_of_video_game_consoles|1st and 2nd generation of video game consoles]], RF connection was the only way to connect a video game console to a TV. During the 3rd generation some consoles such as the NES had separate outputs for unmodulated signals and all consoles had the option by the 4th generation. By the 5th generation, composite video became the standard form of connecting a video game console
;NTSC
:'''[[wikipedia:NTSC|NTSC]]''' was the first color television system to be widely adopted, NTSC works by transmitting a high frequency color signal on top of the legacy black and white image, the amplitude of this signal determines the saturation while the phase determines hue, this is a property that many early consoles and home computers took advantage of. Every nation using the NTSC system also used a 59.94hz field rate. Many [[NTSC filters|filters]] exist to replicate this display on emulators.
