Announcing Google Widevine license delivery services public preview in Azure Media Services

Publicado em 16 novembro, 2015

Senior Program Manager, Azure Media Services

We’re excited to announce Azure Media Services now offers Google Widevine license delivery service in the cloud. Today, in order to deliver Digital Rights Management(DRM) protected content across full range of browsers and devices via HTML5 Encrypted Media Extensions (EME), you will need to support more than one DRM. For instance, IE 11 and Microsoft Edge implemented PlayReady Content Decryption Module (CDM) but Google Chrome implemented Widevine CDM. You may end up encrypt your videos multiple times for each technology. However, with Azure Media services, you now have an end-to-end solution allows you to encrypt your media files only once with ISO MPEG Common Encryption (CENC) and generate multiple DRM header such as Widevine and PlayReady to be streamed to multiple browsers.

Steps involved when configuring an end-to-end multi-DRM DASH stream

  • Encode your media asset once into H.264 multiple bitrate MP4.
  • Azure Media Services will dynamically encrypt your content using Common encryption (CENC) and package it with PlayReady and/or Widevine license header based on your configuration.
  • Azure Media Services delivers MPEG-DASH stream with PlayReady and/or Widevine.
  • Use Azure Media Player to deliver the stream to your web viewers and it will detect your browser and request the allowed license type, such as Widevine for Chrome.
  • Azure Media Services provides out-of-box Token authentication on your license delivery if you want to restrict the audiences based on your specific business logic.
  • Azure Media Services supports both live and video-on-demands stream with Widevine.
