摘要： A system and method for adding auxiliary data DA to an output data stream from a statistical multiplexer is disclosed. An auxiliary multiplexer accepts a statistically multiplexed data stream, and substitutes auxiliary data packets for null data packets. The auxiliary multiplexer controls the number of null packets in the statistically multiplexed data stream by controlling the target bandwidth BT of the statistical multiplexer, or by modifying the statistical multiplexer equation to make the auxiliary data stream a participant in the negotiation process of allocating throughput among the data sources.

摘要： Essential data elements, particularly entitlement control messages (ECMs), are inserted in a manner that reduces the overhead bit rate without effecting overall tuning time at the customer receiver or security in satellite, cable or other programming networks. ECMs are inserted into the transport stream by detecting random access points (RAPS) in the encoded programming and inserting the ECM packets in a window just ahead of the RAP.

摘要： Secure content transfer systems and methods to operate the same are disclosed. An example system includes a content server to encrypt content according to an encryption key, and to transfer the encrypted content, the encryption key and a license to a client that supports a digital rights management technology. The example system further includes a broadcast system headend to determine the encryption key, wherein the broadcast system headend is physically separate from the content server, and a digital rights management license server to provide the license.

摘要： A communication system 100 includes a group of user devices 110, a satellite 106 and a content delivery network 120 in communication with the group of user devices 110. The content delivery network 120 selects a plurality of user devices 110 from the group of user devices 110, divides content into a crucial portion and non-crucial portions, communicates the non-crucial portions to the plurality of user devices using a peer-to-peer network until all non-critical portions are received. After communicating the non-crucial portions, the content delivery network 120 communicates the crucial portion to the plurality of user devices 110 through the satellite. The plurality of user devices assembles the crucial portion and the non-crucial portions to form the content. In addition, security information may be first transmitted through the satellite to the user devices so that a peer-to-peer network may be established. Thereafter, the non-crucial portion are exchanged through the peer-to-peer network.
