METHOD, DEVICE, AND COMPUTER PROGRAM FOR ENCAPSULATING REGION ANNOTATIONS IN MEDIA TRACKS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18194454 titled 'METHOD, DEVICE, AND COMPUTER PROGRAM FOR ENCAPSULATING REGION ANNOTATIONS IN MEDIA TRACKS

Simplified Explanation

The present invention is a method of generating a media file.

  • It involves generating a first track of media data samples.
  • It also involves generating a region track associated with the first track, where each sample of the region track contains information about the geometry of one or more regions in the corresponding sample of the first track.
  • The region description data structure in the region track includes a region identifier for each region.
  • The method further includes generating a region annotation in a container.
  • It also involves generating association metadata that links the region identifier with the region annotation.
  • Finally, a media file is generated that includes the first track, the region track, the region annotation, and the association metadata.


Original Abstract Submitted

The present invention concerns a method of generating a media file, the method comprising: generating a first track of media data samples; generating a region track associated with the first track, each sample of the region track comprising a region description data structure comprising geometry information of one or more regions in at least one corresponding sample of the first track; wherein the region description data structure comprises a region identifier associated with each region; and the method further comprise: generating a region annotation in a container; generating association metadata associating a region identifier with the region annotation; generating a media file including the first track, the region track, the region annotation, and the association metadata.
