Particular applications relate to HD-MAC video signals.
The device is particularly useful in HD-MAC television systems.
The method is particularly suitable for coding HD-MAC television pictures.
The method is useful particularly for frequency doubling in HD-MAC.
HD-MAC (the high definition variant of MAC) was left for transcontinental satellite links, though.
In May 1986, work on the HD-mac standard was officially launched.
To extract the full resolution of the signal, a specific HD-mac decoder was necessary.
To extract the full resolution of the signal, a specific HD-mac decoder was necessary.
An HD-MAC television decoder comprises a 40 ms decoding branch (16-27), and an 80 ms mode decoding branch (38).
HD-mac could be decoded by D2-mac receivers, but in SDTV: in this mode, the displayable resolution was reduced to the standard definition of 576 lines (sullied with certain artefacts).

HD-mac is a standard of analogue transmission of the high definition television which was proposed by the European commission in 1986.

In the case of HD-mac, the data communication channel must guaranty a band-width from at least 11.14 MHz in baseband.

At the time of the Winter Olympics of 1992 and Olympic Games of summer of 1992, public demonstrations of diffusion in HD-mac took place.

However, the launching of satellites of average power by ITS and the use of the PAL enabled them to circumvent HD-mac, thus reducing their cost of diffusion.

60 HD-mac receivers for the plays of Albertville and 700 for the plays of Barcelona were set up in the Eurosites in order to show the possibilities of the standard.
