Claim 21:
22. A non-transitory, computer-readable storage medium having stored thereon instructions that, when executed, cause a processor to:
determine that a media presentation includes first video data at a first spatial resolution and second video data at a second spatial resolution, the second spatial resolution being different than the first spatial resolution;
receive, separately from data of the media presentation, an addressable resource index (ART) track associated with the media presentation, the ARI track including:
a first quality value indicating a first quality of a first portion of the first video data at the first spatial resolution for a first playback time, and
a second quality value indicating a second quality of a first portion of the second video data at the second spatial resolution for the first playback time;

determine, based on the first quality value received in the ARI track and the second quality value received in the ARI track, that the first quality of the first portion of the first video data for the first playback time is higher than the second quality of the first portion of the second video data for the first playback time, wherein the first portion of the first video data and the first portion of the second video data are alternative encoded versions to each other of content included within the media presentation;
in response to the determination that the first quality of the first portion of the first video data is higher than the second quality of the first portion of the second video data, request the first portion of the first video data for the first playback time;
receive the first portion of the first video data at the first spatial resolution for the first playback time;
send the first portion of the first video data at the first spatial resolution to a video decoder;
receive a second portion of the second video data at the second spatial resolution for a second playback time later than the first playback time; and
send the second portion of the second video data at the second spatial resolution to the video decoder.
