Abstract

An apparatus for transferring a complete copy of media designated as time sensitive over a network. The apparatus includes a sending node including a network ascertaining element configured to ascertain 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 the 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 transmitter at the sending node generates and transmits a reduced bit rate representation of the media designated as time-sensitive. The transmitting node is also configured to receive receipt reports from the receiving node that identify the received reduced bit rate representation of the media. In response to the receipt reports, the transmitter at the sending node retransmits the corresponding full bit rate representation of the media. Eventually a complete full bit representation of the media is obtained at the receiving node after the retransmitted media is received.
