  • receiving more than one video stream at a client device over a wireless connection, wherein each of the more than one video stream operates at one of a plurality of bit rates;

    utilizing Real Time Control Protocol (RTCP) and Real Time Protocol between the client device and the associated source of each of the more than one video stream;

    determining quality feedback for each of the more than one video stream utilizing packet loss ratio;

    determining modified quality feedback for each of the more than one video stream wherein the modified quality feedback is based on the quality feedback for each of the more than one video stream; and

    transmitting the modified quality feedback in a RTCP Receiver Report for each of the more than one video stream to an associated source of each of the more than one video stream so that multiple RTCP receiver Reports are transmitted, each having a same modified quality feedback transmitted to each source of the more than one video stream so that each source of the more than one video stream upshifts or downshifts each of the more than one video stream in a uniform manner.
