Abstract: A method for content delivery using dynamic adaptive hypertext transport protocol (HTTP) streaming (DASH) without using HTTP. The method includes receiving a media presentation description (MPD) file and one or more DASH segments by a client device. Information in the MPD file is used to filter the one or more DASH segments. The filtered DASH segments are stored in a segments buffer. Particular DASH segments are requested from the segments buffer by the client device based on the information.

A method for receiving a media license includes receiving broadcast media data including at least a portion that is protected and requesting a message from a content decryption module (CDM) of the receiver. The method includes receiving a license signaling message including encrypted license data and identifying one or more hash codes in the license signaling message. Additionally, the method includes identifying the encrypted license data for the receiver based on a mapping between the one or more hash codes and a hash of the message from the CDM.
