A process for real time protocol (RTP) data streaming includes generating a plurality of codec bitstreams, each codec bitstream being configured to carry encoded information that includes one of occupancy map data, geometry data, or attribute data for a volumetric video. The process includes generating, for each codec bitstream of the plurality, a dedicated RTP stream, the dedicated RTP stream including a RTP payload format based on the respective codec bitstream for that RTP stream. The process includes multiplexing each dedicated RTP stream into a result RTP stream for the volumetric video.

In a depth image compressing section of an image processing device, a depth image operation section generates a depth image by operation using photographed stereo images. A difference image obtaining section generates a difference image between an actually measured depth image and the computed depth image. In a depth image decompressing section of a content processing device, a depth image operation section generates a depth image by operation using the transmitted stereo images. A difference image adding section restores a depth image by adding the computed depth image to the transmitted difference image.

The present disclosure relates to a method and device for transmitting and receiving video content including three-dimensional (3D) data. The method of transmitting video content through a plurality of assets includes identifying whether content transmitted through an asset is a sub-picture; when the content transmitted through the asset is the sub-picture, generating sub-picture asset information comprising information about other sub-pictures constituting a composition picture together with the sub-picture; and transmitting the sub-picture asset information and the content.

Methods and apparatus for processing of volumetric visual data are described. One example method includes decoding, by a decoder, a bitstream containing volumetric visual information for a 3-dimensional scene that is represented as one or more atlas sub-bitstreams and one or more encoded video sub-bitstreams, reconstructing, using a result of decoding the one or more atlas sub-bitstreams and a result of decoding the one or more encoded video sub-bitstreams, the 3-dimensional scene, and rendering a target view of the 3-dimensional scene based on a desired viewing position and/or a desired viewing orientation.

A suggested viewport indication is generated and sent for use in a panoramic video. In one example, a method includes receiving encoded video including viewport metadata, decoding the video, extracting the viewport metadata, generating a viewport of the decoded video based on the viewport metadata, and buffering the generated viewport for display.

System integrating content in real-time into dynamic 3D scene includes external server including CMS, a device including content integrating engine to process in real-time 3D scenes, and display device to display combined 3D scene output. CMS searches for social media posts on social media servers. Social media posts includes message and URL to media content. Content integrating engine includes content retriever, content queue, 3D scene component processors to process each 3D scene's visual components, scene manager and combiner. Content retriever establishes direct connection to external server, and retrieves URLs from server storage and stores URLs in content queue. Scene manager, at time of low intensity during 3D scene, signals to content retriever to retrieve media content corresponding to URLs in content queue, one scene component processor to process display setting change, or another scene component processor to process media content. Combiner to generate combined 3D scene output. Other embodiments are described.
