1. A playback device configured to perform adaptive bitrate streaming of media including a set of alternative video streams, the playback device comprising:

  • memory including a client application and a buffer; and

    a processor, where the client application configures the processor to;

    select a first video stream from a set of alternative video streams, where at least a plurality of 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;

    request chunks of the first video stream via a network connection and store the requested chunks in the buffer;

    playback the buffered chunks of the first video stream;

    measure the channel data rate of the network connection; and

    select a second video stream from the set of alternative streams, where the second video stream has a maximum bitrate that is less than the measured channel data rate.
