DRM protected dynamic adaptive HTTP streaming
Frank H. Hartung, Sinan Kesici, Daniel Catrein · 2011
Dynamic adaptive HTTP streaming (DASH) is a new concept for video streaming using consecutive downloads of short video segments. 3GPP has developed the basic DASH standard which is further extended by the Open IPTV Forum (OIPF) and MPEG. In all versions available to date, only very simple content protection use cases are enabled. Extensions are needed to enable important advanced use cases like pay-per-view and license change in an ongoing video channel.
