Patent ID: 8422382

Claim:
A method for adapting transmission of encoded media in a packet-switched network to different operating conditions, where a plurality of transmission formats are available, said method comprising the steps of: defining each transmission format to include a combination of at least two characteristics, wherein the at least two characteristics include frame aggregation, bit rate, or redundancy, wherein the redundancy includes a number of redundant frames per packet; receiving information that indicates whether a performance metric of the transmitted encoded media fulfills a pre-determined target; if the performance metric of the transmitted encoded media does not fulfill the pre-determined target, selecting another transmission format of the available transmission formats until the performance metric of the transmitted encoded media fulfils the pre-determined target, wherein the selecting another transmission format comprises randomly selecting another transmission format or selecting another transmission format according to a predetermined order; detecting that the performance metric has been improved; selecting added redundancy to the transmission so that a packet size increases to normal size, if the performance metric indicates good qualify, then selecting a less resilient transmission format, or if the performance metric indicates a reduced quality, then returning to the previous transmission format.
