1. A method comprising:

  • receiving a transport packet stream encapsulating a first plurality of media packets;

    generating, for a first media packet that is identified as a point-of-interest (POI) media packet, a first reference to the POI media packet relative to the location of the first media packet within the transport packet stream, wherein generating the first reference comprises;

    generating a first flow identifier identifying a first transport packet of the transport packet stream that encapsulates the first media packet, wherein the first transport packet comprises a second plurality of media packets, and wherein the first flow identifier comprises a destination address, a destination port, and a synchronization source identifier (SSRC), andgenerating a first transport packet reference comprising a first position reference in the first transport packet for the first media packet;

    generating a second reference for a second media packet that is identified as the POI media packet;

    adding the first reference to an auxiliary stream, the auxiliary stream being separate from the transport packet stream, the auxiliary stream comprising one or more references to one or more media packets in the transport packet stream identified as the POI media packet, wherein adding the first reference comprises adding the first flow identifier and the first transport packet reference to the auxiliary stream; and

    adding the second reference to the auxiliary stream, wherein adding the second reference comprises adding, when the second media packet is located in the first transport packet, a second transport packet reference comprising a second position reference in the first transport packet for the second media packet.
