Abstract

The embodiments of the invention provide a method for media data processing, and an apparatus thereof. The method for media data processing comprises: obtaining every media fragment in a coding expression; and performing content protection for at least a part of the media fragments in the coding expression. The embodiments of the method, through making the media fragments in the coding expression as a content protection unit, enable content protection for at least a part of the media fragments in the coding expression, and make the protection modes of the media fragments in the coding expression differentiated, so that reliability and flexibility of the content protection for HTTP streaming media services are improved.

Description

technical field [0001] Embodiments of the present invention relate to audio and video technologies, and in particular, to a media data processing method and device thereof. Background technique [0002] With the popularization of the Internet, the streaming media service has developed rapidly, and the streaming media service based on the hypertext transfer protocol (Hyper Text Transfer Protocol, hereinafter referred to as: HTTP) is one of them. [0003] The prior art adopts content protection for the HTTP streaming media service, so that the rights and interests of the owners of the streaming media content are protected. Specifically, in the HTTP Streaming standard of 3GPP, content protection is based on a content segment. A content paragraph corresponds to the duration of a certain piece of content. There is at least one coded expression in the content paragraph, and each coded expression contains several media fragments. Media fragments within each encoded representation...
