1. An information processing device comprising:
circuitry configured to
generate scalable decoding information regarding scalable decoding of geometry-based point cloud compression (G-PCC) content on a basis of depth information indicating a quality hierarchy level of each slice in the G-PCC content including first and second slices and a dependency relation between the first and second slices in the G-PCC content, wherein the scalable decoding information includes track configuration information regarding a configuration of a track that stores the G-PCC content on a slice basis in the content file, wherein the track configuration information includes
track depth information regarding the depth information of the geometry of all the slices included in the track corresponding to the track configuration information, and
generate a content file that stores the G-PCC content and to store the scalable decoding information in a metadata area of the content file,
wherein the track depth information includes track minimum depth information indicating a minimum value of the depth information in the track and track maximum depth information indicating a maximum value of the depth information in the track.
