1. A method comprising:

  • obtaining a plurality of representations of a digital video asset, wherein the plurality of representations comprise a plurality of video frames;

    generating an acyclic directed graph comprising a plurality of nodes representing the plurality of video frames and a plurality of arcs representing temporal dependencies and frame decoding dependencies between each video frame of the plurality of video frames, wherein the frame decoding dependencies comprise a plurality of switching points between the plurality of representations of the digital video asset, wherein a first arc of the plurality of arcs is associated with a first switching point from the plurality of switching points and wherein the first arc comprises a quality loss metric;

    receiving, from a first computing device, a request for a first representation of the plurality of representations of the digital video asset; and

    transmitting, to the first computing device, the acyclic directed graph in response to receiving the request.
