− | '''NTSC filters''' replicate the analog signals that the console's output to the TV. They vary in quality, with the lowest quality being RF, then composite, then s-video and RGB (SCART)/YPbPr (Component) being the highest quality. Many emulators have NTSC filters built into them. They can also be separately downloaded as filter plugins. These filters were developed by blargg<ref>http://slack.net/~ant/libs/ntsc.html</ref> for specific consoles. Other NTSC shaders have been created which are different from blargg's implementation | + | '''NTSC filters''' replicate the analog signals that the console's output to the TV.

Encoding ''luminance'' (or ''luma'', the brightness component of the signal) and ''chrominance'' (or ''chroma'', the color component of the signal) into a single signal is what causes blur and artifacts because it's a lossy way of encoding an image. RF has worse artifacts because it also encodes audio into the signal and is more prone to interference since the signal is the same as what was used TV broadcasts. | Encoding ''luminance'' (or ''luma'', the brightness component of the signal) and ''chrominance'' (or ''chroma'', the color component of the signal) into a single signal is what causes blur and artifacts because it's a lossy way of encoding an image.
