摘要： Methods and apparatus for an efficient multicast file distribution system. A method for transmitting a file over a distribution network includes encoding the file with a selected encoding scheme to form encoded packets, generating file delivery protocol (FDP) packets from the encoded packets, generating a file delivery control protocol (FDCP) packet that comprises control information associated with the FDP packets, and transmitting the FDCP packet and the FDP packets over the distribution network. A method for receiving a file over a distribution network includes receiving a FDCP packet and FDP packets, decoding the FDP packets based on the FDCP packet to generate encoded packets, and generating at least a portion of the file from the encoded packets.

摘要： Methods and apparatus to reduce channel switching time. A method for channel switching includes bundling entitlement control messages (ECMs) to generate bundled ECMs that comprise decryption keys associated with a first content channel and one or more additional content channels, respectively, and transmitting the bundled ECMs with the first content channel. An apparatus for channel switching includes key acquisition logic configured to receive bundled ECMs that comprise decryption keys associated with a first content channel and one or more additional content channels, respectively, processing logic configured to receive a request to render a second content channel that is part of the one or more additional content channels, and decryption logic configured to utilize a selected decryption key obtained from the bundled ECMs to decrypt the second content channel.

摘要： Systems and methodologies are described that facilitate broadcasting and receiving messages in a wireless media broadcast network. Mobile devices are equipped to receive media over a broadcast network where presentation of the data can be enabled through a content policy. Broadcast messages can be provisioned and delivered over the network such that mobile devices can receive the message regardless of the level or existence of purchased content. The messages can be broadcast for multiple purposes, including emergency messages, which can come from an emergency or amber alert system, venue and/or location specific messages, etc. The messages can be broadcast at a regional level as well by leveraging such functionality of the media broadcast network.
