Classification: CPC H  G | IPC H

Claim 6:
7. A reproduction processing method for causing circuitry to execute processes comprising:
receiving information of a content including a plurality of component streams, wherein the plurality of component streams include a metadata stream;
acquiring content RAP information indicating a random access point of the content from the information of the content;
specifying a random access point of each of the component streams on a basis of the content RAP information that has been acquired;
reproducing the content from a random access point of each of the component streams that has been specified; and
determining, based on the content RAP information stored in a metadata area, content RAP information of the plurality of component streams, and
wherein the content is video codec based point cloud compression (V-PCC) content, and a content file in which the content RAP information is stored in the metadata stream of the file is an ISOBMFF-compliant file; and
storing a flag in a sample entry of a metadata track for the metadata stream, wherein the flag indicates that the content RAP information stored in the metadata stream is RAP information of the V-PCC content that satisfies a condition that the content RAPs are of a same type in the plurality of component streams.
