February 4, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- A patent application by the inventors Wang, Xin (Rancho Palos Verdes, CA); Zhang, Shaobo (Shenzhen, CN); Giladi, Alexander (Princeton, NJ); Liu, Yongliang (Beijing, CN); Liu, Tao (Shenzhen, CN), filed on July 12, 2013, was made available online on January 23, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application has not been assigned to a company or institution.

The following quote was obtained by the news editors from the background information supplied by the inventors: "A media content provider or distributor may deliver various media contents to subscribers or users using different encryption and/or coding schemes suited for different devices, e.g., televisions, notebook computers, and mobile handsets. The media content provider may support a plurality of media encoder and/or decoders (codecs), media players, video frame rates, spatial resolutions, bit-rates, video formats, or combinations thereof. A piece of media content may be converted from a source or original representation to various other representations to suit the different user devices."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "In one embodiment, the disclosure includes an apparatus comprising a memory, a processor coupled to the memory and configured to obtain a protection description for media content comprising a plurality of content items, wherein the protection description comprises data signaling at least two protection mechanisms for at least two content items in a media content, wherein each of the at least two content items is protected by one or more of the at least two protection mechanisms, and wherein the protection mechanisms for the at least two content items are different, determine the protection mechanisms for the at least two content items from the data, and process the at least two content items according to their associated protection mechanisms.

"In another embodiment, the disclosure includes a computer program product comprising computer executable instructions stored on a non-transitory computer readable medium such that when executed by a processor cause a network element (NE) to obtain a protection description for media content, wherein the media content comprises a plurality of encrypted content items, and wherein the protection description comprises data signaling at least two protection mechanisms for at least two encrypted content items described in a media description, where each of the at least two encrypted content items is associated with one or more of the at least two protection mechanisms, and wherein the protection mechanisms for the at least two encrypted content items are different, determine the associated protection mechanisms from the data for the at least two encrypted content items, and process the at least two encrypted content items according to their associated protection mechanisms.

"In yet another embodiment, the disclosure includes a method comprising obtaining a media content comprising at least two content items, wherein each of the at least two content items are protected by one or more of at least two protection mechanisms, and wherein the protection mechanisms for each of the at least two content items is different, developing a protection description for the media content, wherein the protection description comprises data sufficient to signal the protection mechanisms for the at least two content items, and transmitting the protection description to a client.

"In still another embodiment, the disclosure includes an apparatus comprising a memory, a processor coupled to the memory and configured to obtain a media content comprising at least two content items, wherein each of the at least two content items are protected by one or more of at least two protection mechanisms, and wherein the protection mechanisms for each of the at least two content items is different, develop a protection description for the media content, wherein the protection description comprises data sufficient to signal the protection mechanisms for the at least two content items, and transmit the protection description and the media content to a client.

"These and other features will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings and claims.

BRIEF DESCRIPTION OF THE DRAWINGS

"For a more complete understanding of this disclosure, reference is now made to the following brief description, taken in connection with the accompanying drawings and detailed description, wherein like reference numerals represent like parts.

"FIG. 1 is a schematic diagram of an embodiment of a Dynamic Adaptive Streaming over Hypertext Transfer Protocol (HTTP) (DASH) enabled network architecture.

"FIG. 2 is a protocol diagram of an embodiment of a DASH communication method.

"FIG. 3 is a schematic diagram of an embodiment of a DASH delivery process model.

"FIG. 4 is a schematic diagram of an embodiment of a DASH client process model.

"FIG. 5 is a schematic diagram of an embodiment of a NE."
