Lesson plan
A-MAC
transmission of all TV-picture elements and the multiplexed transmission of the TV picture elements with D2-MAC. In television electronics, A-MAC is a form of analog video encoding, specifically a type of Multiplexed Analogue Components (MAC) encoding. It carries digital information: sound, and data-teletext on an FM subcarrier at 7 MHz. Since the vision bandwidth of a standard MAC signal is 8.4 MHz, the horizontal resolution on A-MAC has to be reduced to make room for the 7 MHz carrier. A-MAC has not been used in service.
