DRM RECEIVERS AND EQUIPMENT (Download here)

Note to the Manufacturers of DRM equipment

Equipment implementing the coding and modulation part of DRM requires the use of certain essential patents for which manufacturers need to make agreements with the patent holders.  The audio part of DRM falls entirely within the licencing of AAC undertaken by Via Licensing, a Licensing Administrator acting on behalf of the AAC licensor patent pool – see www.vialicensing.com.  The DRM Association and the DRM Consortium do not make any charges for the use of the DRM technology.
