MAC encoding was designed in the mid 80s for use with Direct Broadcast Satellite systems. Other analog video encoding systems include NTSC , PAL and SECAM . Unlike the Frequency division multiplexing FDM method used in those, MAC encoding uses a Time division multiplexing TDM method. B MAC was a proprietary MAC encoding used by Scientific Atlanta for encrypting broadcast video services the full name was Multiple Analogue Component, Type B . ref http www.mlesat.com encryption.html Satellite Signal Encryption ref B MAC uses teletext style non return to zero NRZ signaling with a capacity of 1.625 Mbit s. The video and audio data signals are therefore combined at baseband. Both PAL 626 50 and NTSC 525 60 versions of B MAC were developed and used.

From left to right digital data, chrominance and luminance C MAC is the variant approved by the European Broadcasting Union EBU for satellite transmissions. The digital information is modulated using 2 4PSK phase shift keying , a variation of quadrature PSK where only two of the phaser angles 90 are used. The channel capacity data capacity for C MAC is 3Mb s. C MAC data has to be sent to the transmitter separately from the vision. The transmitter switches between FM vision and PSK sound data modulation during each television line period. C MAC variants E MAC E MAC Extended MAC is 16 9 version of C MAC. Originally E MAC was designed for 15 9 pictures, it later adopted the 16 9 aspect ratio. In E MAC all the 4 3 information is transmitted exactly as in C MAC so that C MAC receivers are still compatible. E MAC hides extra luminance and chrominance information in the field blanking interval and parts of the line blanking interval. E MAC has a lower data capacity because luminance is hidden where data would usually be located. A steering signal is transmitted to indicate to the 16 9 receiver whereabouts the 4 3 picture information. E MAC receivers stitch the 4 3 and helper wide screen data into a seamless 16 9 picture.
