US Patent 11184665 Initialization set for network streaming of media data

A device for retrieving media data includes a memory configured to store media data of a media presentation; and one or more processors implemented in circuitry and configured to: retrieve a manifest file for the media presentation, the manifest file including data for an initialization set, the initialization set including initialization parameters for the full duration of the media presentation; initializing playback of the media data of the media presentation using the initialization set; retrieving the media data of the media presentation; and present the media data according to the initialized playback. For example, the initialization parameters may specify a maximum width or a maximum height of pictures of the media presentation or a maximum frame rate of the media presentation. Thus, the processors can process pictures of any size less than or equal to the maximum width/height, or media data equal to or less than the maximum frame rate.
