    receiving a request for content from a playback device, wherein the request comprises;

    an electronic token to obtain access to the content,information indicative of a geographic location of the playback device, anddevice information related to the playback device;

    determining a set of alternative video streams from the plurality of alternative video streams to return based on the request;

    generating a top level index file describing each of the set of alternative video streams, wherein the top level index file describes the assets that are best suited to playback on the playback device;

    retrieving cryptographic information, where the cryptographic information is used to access protected streams described in the top level index file; and

    providing the cryptographic information and the top level index file to the playback device using the playback server.
