Abstract
A method of transmitting a video stream over an IP network. The method includes encoding a source video into a plurality of packets. The method also includes measuring a real-time transmission status of a current set of the plurality of packets. The method also includes mapping a utility curve for the video which reflects utilities of the video at corresponding sending rates. The method also includes calculating a target sending rate for a next set of the plurality of packets according to the real-time transmission status of the current set of the plurality of packets and the utility curve. The method also includes determining a proper strategy to meet the target sending rate for the next set of the plurality of packets.
