1. An adaptive bit rate streaming system that includes a content server and a source encoder server, the system comprising:

  • a source encoder server configured to encode source video as a number of alternative video streams, the source encoder comprising;

    memory; and

    a processor configured by a source encoding application stored in the memory to;

    receive multimedia content, where the multimedia content comprises source video data having a primary resolution and a primary sample aspect ratio;

    encode the source video data as a set of alternative video streams, where;

    the alternative video streams have different maximum bitrates; and

    the alternative video streams are encoded to have an upper bound seek delay that is equal to or less than the upper bound seek delay of streams in the set of alternative video streams that are encoded at a higher maximum bitrate where the upper seek bound delay of a particular one of the alternative video streams is determined as follows;
