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.
In an intermediate node disposed between a source node and a plurality of receiving nodes in a network, a method for transcoding a stream of data packets, said method comprising the steps of:
A device for transcoding a stream of data packets, wherein said device is an intermediate node disposed between a source node and a plurality of receiving nodes in a network, said device comprising:
A computer-usable medium having computer-readable program code embodied therein for causing a transcoder to perform the steps of:
