Sign in to saveAlso known as High Definition Multiplexed Analogue Components
HD-MAC (High Definition Multiplexed Analogue Components) was a broadcast television standard proposed by the European Commission in 1986, as part of Eureka 95 project. It belongs to the MAC - Multiplexed Analogue Components standard family. It is an early attempt by the EEC to provide high-definition television (HDTV) in Europe. It is a complex mix of analogue signal (based on the Multiplexed Analogue Components standard), multiplexed with digital sound, and assistance data for decoding (DATV). The video signal (1250 lines/50 fields per second in 16:9 aspect ratio, with 1152 visible lines) was

The video signal (1250 lines/50 fields per second in 16:9 aspect ratio, with 1152 visible lines) was encoded with a modified D2-MAC encoder.
HD-MAC could be decoded by normal D2-MAC standard definition receivers, but no extra resolution was obtained and certain artifacts were visible. To decode the signal in full resolution a specific HD-MAC tuner was required .
