HD-MAC
HD-MAC is a precursor of the DVB standard. It was an early attemp by the EEC to provide HDTV in Europe.Unlike DVB, HD-MAC was a complex mix of analogue and digital.
Video and audio were uncompressed, and required up to 36 mhz per transmission.
Video was broadcasted using a modified D2-MAC encoder. Standard resolution was 1250 lines/50 frames in 16:9 aspect ratio.
HD-MAC could be decoded by a standard D2-MAC receivers, but in that mode only 625 lines were available. In order to decode the signal in full resolution, an specific HD-MAC tuner was needed.
In the 1992 Summer Olympics, an experimental HD-MAC broadcasting took place. 100 HD-MAC receivers (in that time, retroprojectors ) in Europe were used to test the capabilities of the standard. This project was financed by the EEC. The PAL-converted signal was used by regular broadcasters such as SWR, BR,BR,EBU)
