  • Publication number: 20220053224
    Abstract: The present disclosure relates to information processing apparatus and method that allow robustness of content reproduction to be improved. Metadata regarding content is generated, the content expressing a three-dimensional object in a three-dimensional space and enabling a line-of-sight direction and a view-point position to be freely set at a time of reproduction, and the metadata including information enabling a bit rate to be selected at a time of distribution of the content. Metadata that includes, for example, as the above-described information, access information for a control file controlling reproduction of the content, is generated. The present disclosure may be applied to, for example, an image processing apparatus, an image encoding apparatus, or an image decoding apparatus.
