On April 5th, 2016, the DVB passed to high definition (HD)

All with the HD

Digital terrestrial television (DVB) was modernized by generalizing the HD: since April 5th, 2016, most chains are diffused in HD with a better quality of image and sound. This operation was carried out at the time of the transfer of the frequencies of band 700 MHz to the profit as of mobile operators, decided by the Government.

This technical operation proceeded in one night, from April 4th to April 5th, 2016, on all the Metropolitan France. 

This evolution was possible thanks to the generalization of the standard of coding MPEG-4 to the whole of the platform of the DVB. More recent and more powerful, it makes it possible many chains to be diffused in high definition.

Until April 5th, on the 31 national chains which account platform DVB, only 11 were diffused in HD :

  • TF1, France 2, Canal+, Arte and M6 (since October 2008)
  • D1, L'Equipe 21,6Ter, Number 23, RMC Discovered and Cherished 25 (since March 2012)

Thanks to the standard MPEG-4, the number of chains diffused in HD more than doubled
