Abstract: A system protects content, by detecting, by a first application interface, a message attribute associated with content received by the first application interface. A syntax parser on a first application parses the content to identify the message attribute. The first application interface embeds a protect attribute in metadata associated with the content, where the protect attribute indicated by the message attribute. The system transmits the content from the first application interface to a second application interface. The second application interface extracts the protect attribute from the metadata associated with the content. The system applies the protect attribute to the content rendered by the second application interface. The system propagates the protect attribute applied to the content when the content is transmitted from the second application interface to at least one third application interface, and then applies the protect attribute to the content rendered by the third application interface.

Abstract: A method and system for unified caching of media content are described. The system includes a streaming media protocol engine to receive a request for a data stream in a first format from a client system; a streaming media mass storage subsystem to locate the data stream stored by a cache server in a second format; and a network protocol engine to serve the located data stream to the client system in the first format.
