INFORMATION PROCESSING DEVICE, INFORMATION RECORDING MEDIUM, INFORMATION PROCESSING METHOD, AND PROGRAM
Zusammenfassung
[0001] To enable an HDR image and an HDR image metadata to be stored in an MP4 file, and a reproduction device to reproduce an optimum HDR image based on metadata. In generating the MP4 file that stores HDR image data, the HDR image metadata is recorded in the MP4 file. An HDR image metadata storage box is set to a trak box or a traf box in the MP4 file, and the HDR image metadata is stored. The reproduction device acquires the HDR image metadata stored in the MP4 file, determines whether executing a conversion process of the HDR image read from the MP4 file according to the acquired metadata and display function information of the display unit, and executes an output image generation process according to a determination result.

warum
Sony HDR-video MP4 file format + reproduction logic — primarily a digital-video Computing topic. H04N (broadcast/video) supports a Telecommunications secondary. The rule classifier returns 'Audio, Telecommunications' because G11B is mapped to Audio in sectorRules; here the patent is about video metadata, not audio, so the Audio tag is a drift artefact.
