Abstract: An example device for retrieving media data includes a memory configured to store media data; and one or more processors implemented in circuitry and configured to: retrieve data of an addressable resource information (ARI) track of a media presentation, the data of the ARI track describing addressable resources and subsets of a switching set of the media presentation, the switching set comprising a plurality of media tracks including the addressable resources, the ARI track being a single index track of the media presentation, the addressable resources comprising retrievable media data; determine durations and sizes of the addressable resources from the data of the ARI track; determine one or more of the addressable resources to retrieve using the data of the ARI track including the durations and sizes of the addressable resources; retrieve the determined addressable resources; and store the retrieved addressable resources in the memory.
