An information processing apparatus and method, and a reproduction processing device and method alleviate processing load at the time of providing content. An MPD generation unit generates an MPD of an image divided by unit area. A metadata generation unit generates viewport rings by, based on an MPD and viewport information indicating a line-of-sight direction for each of priorities determined in advance corresponding to a center of a reference line-of-sight direction, grouping AdaptationSets corresponding to a predetermined area of each of the priorities designated by each piece of the viewport information and grouping AdaptationSets corresponding to each surrounding area of the predetermined area determined by the unit area, generates a viewport ring group by grouping the viewport rings on the basis of the center of the reference line-of-sight direction, and generates a viewport ring group list by listing information regarding a plurality of the viewport ring groups.
