Carriage of Point Cloud Data Progresses to Committee Draft
At its recent 127th meeting, WG11 (MPEG) promoted the carriage of point cloud data (ISO/IEC 23090-10) to the Committee Draft stage, the first milestone of ISO standard development process. This standard is the first one introducing the support of volumetric media in the industry-famous ISO base media file format family of standards. This standard supports the carriage of point cloud data comprising individually encoded video bitstreams within multiple file format tracks in order to support the intrinsic nature of the point cloud compression (ISO/IEC 23090-5).
Additionally, it also allows the carriage of point cloud data in one file format track for applications requiring multiplexed content (i.e., the video bitstream of multiple components is interleaved into one bitstream). This standard is expected to support efficient access and delivery of some portions of a point cloud object considering that in many cases that entire point cloud object may not be visible by the user depending on the viewing direction or location of the point cloud object relative to other objects. It is currently expected that the standard will reach its final milestone by the end of 2020.
