Why do you call DRM the newest and most complete digitisation solution for terrestrial broadcasting?
The DRM technical standard was devised by a group of forward looking engineers from countries like UK, USA, Germany, France and others and is available free-of-charge from the ETSI. The ITU has approved its use in most of the world. So, DRM details are published in open standards issued by both ETSI and the ITU-R.
The inaugural DRM broadcast took place on June 16, 2003, in Geneva, Switzerland, at the ITU’s World Radio Conference. The extension of the standard to the VHF bands took place in 2011. In 2012 DRM aligned with the mobile industry and went for the DRM MPEG specified xHE-AAC codec, which can provide fair quality below 12 kb/s. DRM can provide quality in the AM band that matches or exceeds current analogue FM audio quality.
But DRM is just one standard with the same benefits and features on all frequency bands: DRM for the AM bands and DRM for the VHF bands. The combination of improved spectral efficiency and the improved audio codec allow DRM to provide both higher audio quality and additional multimedia services.
