INFORMATION PROCESSING APPARATUS AND METHOD

摘要

The present disclosure relates to an information processing apparatus and an information processing method that enable recognition of performance required for decoding more accurately. A file of an MP4 file format, in which information specifying a plurality of NAL units corresponding to a partial image which can be independently decoded in a whole image is stored in moov and the encoded partial image is stored in mdat, is generated, and the generated file is transmitted. The present disclosure can be applied to, for example, an information processing apparatus such as an image encoding apparatus or an image decoding apparatus.

主权项

1. An image decoding apparatus comprising:
an acquiring unit configured to acquire subsample information from a file including encoded data of image data and management information of the encoded data, in which the subsample information of an image of the image data is arranged, the subsample information including hint information used as a reference for decoding processing of a subsample, which is a partial region which can be independently decoded; an encoded data generating unit configured to generate encoded data of the subsample from the encoded data included in the file based on the subsample information acquired by the acquiring unit; and a decoding unit configured to decode the encoded data of the subsample generated by the encoded data generating unit.
