Multiplexed Analogue Components

Multiplexed Analogue Components (MAC) was an <a href="/facts/Analog_television/4NJJew1c">analog television</a> standard where <a href="/facts/Luminance/yAqK94ny">luminance</a> and <a href="/facts/Chrominance/Ejtq4s5r">chrominance</a> components were transmitted separately. This was an evolution from older color TV systems (such as <a href="/facts/PAL/t8TugcxK">PAL</a> or <a href="/facts/SECAM/vexpud7W">SECAM</a>) where there was interference between chrominance and luminance.
MAC was originally proposed in the 1980s for use on a Europe-wide <a href="/facts/Terrestrial_television/3nTUr9cY">terrestrial</a> <a href="/facts/High-definition_television/AuE6FRFI">HDTV</a> system. Terrestrial transmission tests were conducted in France, although the system was never used for that purpose. Various variants were developed, collectively known as the "MAC/packet" family.
In 1985 MAC was recommended for <a href="/facts/Satellite_television/UxytxnPW">satellite</a> and <a href="/facts/Cable_television/GzXa4pbW">cable broadcasts</a> by the <a href="/facts/European_Broadcasting_Union/J4o57Hqa">European Broadcasting Union (EBU)</a>, with specific variants for each medium. <a href="/facts/C-MAC/2edpEKKF">C-MAC/packet</a> was intended for <a href="/facts/Satellite_television/UxytxnPW">Direct Broadcast Satellite (DBS)</a>, <a href="/facts/D-MAC/EPfsMVYN">D-MAC/packet</a> for wide-band cable, and <a href="/facts/D2-MAC/NUNeIQUu">D2-MAC/packet</a> for both for DBS and narrow-band cable.
