METHODS AND APPARATUS FOR ADAPTIVE STREAMING OF POINT CLOUDS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240323243 titled 'METHODS AND APPARATUS FOR ADAPTIVE STREAMING OF POINT CLOUDS

The patent application is focused on adaptive streaming of V-PCC (Video-based Point Cloud Compression) data using an adaptive HTTP streaming protocol like MPEG DASH.

  • Signaling the point cloud data in a DASH MPD with a main adaptation set for the point cloud and a plurality of component adaptation sets for V-PCC components.
  • Including unique values in the attributes to signify V-PCC data and transmitting the DASH bitstream over the network.
      1. Potential Applications:

This technology can be applied in video streaming services, virtual reality applications, augmented reality experiences, and 3D modeling software.

      1. Problems Solved:

The technology addresses the challenges of efficiently streaming and compressing large point cloud data, ensuring a smooth and adaptive viewing experience for users.

      1. Benefits:

- Improved streaming quality for V-PCC data - Enhanced user experience with adaptive streaming - Efficient compression and transmission of point cloud data

      1. Commercial Applications:

This technology can be utilized by streaming platforms, VR/AR developers, and software companies to enhance their products' performance and user experience.

      1. Prior Art:

Original Abstract Submitted

methods, apparatus, and systems directed to adaptive streaming of v-pcc (video-based point cloud compression) data using an adaptive http streaming protocol, such as mpeg dash. a method includes signaling the point cloud data of the point cloud in a dash mpd including: a main adaptationset for the point cloud, including at least (1) a @codecs attribute that is set to a unique value signifying that the corresponding adaptationset corresponds to v-pcc data and (2) an initialization segment containing at least one v-pcc sequence parameter set for a representation of the point cloud; and a plurality of component adaptationsets, each corresponding to one of the v-pcc components and including at least (1) a vpcccomponent descriptor identifying a type of the corresponding v-pcc component and (2) at least one property of the v-pcc component; and transmitting the dash bitstream over the network.
