摘要： Assisted peer-to-peer media streaming. A first connection to at least one peer of a peer-to-peer network is initiated for receiving media content from the peer-to-peer network. Responsive to a disruption of delivery of the media content over the first connection from the peer, the media content is received over a second connection with a data source, wherein the data source comprises the media content.

摘要： A method and system for securely and scalably encoding data are disclosed. A method and system for decoding data which has been securely and scalably encoding are also disclosed. In one encoding method embodiment, the present invention recites receiving data. The present method then segments the data into corresponding regions. The regions are then scalably encoded into scalable data. The present embodiment then progressively encrypts the scalable data to generate progressively encrypted scalable data. Next, the present embodiment packetizes the progressively encrypted scalable data.

摘要： A method and system for transcoding a stream of data packets are disclosed. The data packets are received from a source node and include data that are encrypted. The stream of data packets is operated on by a function that configures the stream according to downstream attributes, such as the attributes of a receiving node or of the communication channel. Significantly, the function is performed without decrypting the encrypted media data. The steam of data packets configured for the downstream attributes is sent to the receiving node. Because the encrypted data do not need to be decrypted and then encrypted again, the computational resources needed for transcoding the stream of data packets is significantly reduced, and the security of the data is not compromised.

摘要： A compression and transmission method and system for use to communicate information from a first device to a second device in a network of devices. First, the first device receives information to be communicated to the second device. Second, the first device compresses the information to be communicated by employing prior information of the first device and prior information of the second device. The compressed information is then transmitted to the second device.
