Document Type and Number:
WIPO Patent Application WO/2020/189051
Kind Code:
A1
Abstract:
Provided are an information processing device, an information processing method, a reproduction processing device, and a reproduction processing method that reduce a processing load at the time of providing content. An MPD generation unit generates MPD of an image divided by a unit region. A metadata generation unit generates each viewport ring, on the basis of viewport information indicating a sight line direction for each predetermined priority corresponding to the MPD and the reference sight line direction center, by grouping of AdaptationSet corresponding to a prescribed region for each priority designated by each viewport information, and grouping of AdaptationSet corresponding to each peripheral region of a prescribed region determined by the unit region, generates a viewport ring group by grouping the viewport rings on the basis of the reference sight line direction center, and generates a viewport ring group list by listing information of a plurality of viewport ring groups.
