TELECOMMUNICATION AND MULTIMEDIA MANAGEMENT METHOD AND APPARATUS
First Claim
1. A method for transferring a complete copy of media designated as time sensitive over a network, comprising:
- ascertaining if conditions on the network are adequate to transmit a full bit rate representation of media designated as time-sensitive at a first bit rate and a first packetization interval between a sending node and a receiving node over the network, the full bit rate representation being derived from when the time-sensitive media was originally encoded;
generating a reduced bit rate representation of the media designated as time-sensitive if network conditions are ascertained as being inadequate;
transmitting the reduced bit rate representation of the media from the sending node to the receiving node if network conditions are ascertained as being inadequate;
receiving receipt reports at the sending node, the receipt reports generated by the receiving node and identifying the reduced bit rate representation of the media received at the receiving node and including a low priority request for retransmission of the identified media;
retransmitting the full bit rate representation of the media corresponding to the media identified in the receipt reports from the sending node to the receiving node; and
eventually obtaining a complete full bit representation of the media at the receiving node after the retransmitted media is received.

Abstract
A method for transferring a complete copy of media designated as time sensitive over a network. The method involves ascertaining if conditions on the network are adequate to transmit a full bit rate representation of media designated as time-sensitive at a first bit rate and a first packetization interval between a sending node and a receiving node over the network, where the full bit rate representation being derived from when the time-sensitive media was originally encoded. If the network conditions are ascertained as being inadequate, then a reduced bit rate representation of the media designated as time-sensitive is generated and transmitted to the receiving node. At the receiving node, receipt reports are generated identifying the received reduced bit rate representation of the media. The receipt reports are transmitted to the sending node, where, in response, the corresponding full bit rate representation of the media is retransmitted. Eventually a complete full bit representation of the media is obtained at the receiving node after the retransmitted media is received.
