Abstract
Methods and systems for controlling quality of a media stream in a media session. The described methods and system control the quality of the media stream by controlling transcoding of the media session. The transcoding is controlled at the commencement of the media session and dynamically during the life of the media session. The transcoding is controlled by selecting a target quality of experience (QoE) for the media session, computing a predicted QoE for each of a plurality of control points, where each control point has a plurality of transcoding parameters associated therewith, selecting an control point of the plurality of control points, wherein the predicted QoE for the selected control point substantially corresponds with the target QoE and signaling the transcoder to use the selected control point for the media session.
