- Among the family of MAC or Multiplexed Analogue Components systems for television broadcasting, D-MAC is a reduced bandwidth variant designed for transmission down cable.
* The data is duobinary coded with a data burst rate of 20.25Mbit/s so that 0° as well as ±90° phasors are used.
* D-MAC has a bandwidth of 8.4 MHz versus 27 MHz for C-MAC.
* Most cable systems work on EBU 7 MHz channel spacing, so this approach did not work universally.
* D-MAC's bandwidth problems were later fixed by D2-MAC. (en)
- Il D-MAC è un sistema di trasmissione televisiva, appartenente alla famiglia dei sistemi MAC. I componenti del segnale televisivo sono trasmessi separatamente tramite un processo di multiplazione (Multiplexed Analog Components).In particolare, il D-MAC è una variante a larghezza di banda ridotta, concepita per la trasmissione via cavo.
