Abstract:
1. A method, comprising: ascertaining whether media to be sent from a sending node to a receiving node is time-sensitive, the time-sensitivity of the media being ascertained from an intent of a recipient to review the media upon receipt; transmitting the media ascertained as time-sensitive from the sending node to the receiving node, the media initially transmitted at a first bit rate and at a first packetization interval, the first bit rate and the first packetization interval sufficient for a full bit rate representation of the media to be reviewed upon receipt, the full bit rate representation of the media being derived from when the media was originally encoded; receiving at the sending node receipt reports from the receiving node, the receipt reports including parameters indicative of media loss on the network between the sending node and the receiving node; ascertaining at the sending node available bandwidth on the network between the sending node and the receiving node based on the receipt reports; ascertaining if the available bandwidth on the network is sufficient to support the continued transmission of the full bit rate representation of the media ascertained as time-sensitive at the first bit rate and the first packetization interval; and selectively performing: a. continuing the transmission of the full bit rate representation of the media ascertained as time-sensitive at the first bit rate and the first packetization interval when the available bandwidth on the network is sufficient; b. transmitting a reduced bit rate representation of the media ascertained as time-sensitive when the available bandwidth on the network is not sufficient for the full bit rate representation but is above a minimum bandwidth for the reduced bit rate representation, the reduced bit rate representation of the media generated by performing one or more of the following: c. transmitting the media ascertained as time sensitive as a time-shifted communication when the available bandwidth is lower than the minimum bandwidth for the reduced bit rate representation; whereby the transmission of the reduced bit rate representation of the media ascertained as time-sensitive enhances the timeliness of the delivery of the media so as to increase the ability of the recipient to review the media upon receipt when the available bandwidth on the network is not sufficient to transmit the full bit rate representation of the media at the first bit rate and the first packetization interval.
