Abstract: A technique for managing transmission quality for objects in a copresence session includes obtaining representation data for a virtual representation of a subject. A first bitrate and a second bitrate are determined, where the first bitrate satisfies a first quality metric for a first data quality tier, and the second bitrate satisfies a second quality metric for a second quality tier. A set of data quality tiers are generated for the representation of the subject based on the first bitrate and the second bitrate.

Abstract: A technique for transmitting data in a copresence environment includes initiating a virtual communication session between a local device and remote devices in a shared copresence environment, where each of the plurality of sending devices are transmitting a sending quality data stream in the virtual communication session. A region of interest for the local device is determined that includes a portion of the copresence environment. The local device subscribes to a first quality data stream for the remote devices represented in the region of interest, and a second quality data stream for the remote devices not represented in the region of interest.

Abstract: Various implementations disclosed herein include devices, systems, and methods that enable compression of two-dimensional (2D) map-based video content. For example, a process may obtain (2D) data sets corresponding to different attributes of three-dimensional (3D) content. Each of the 2D data sets may provide attribute values for locations within a common 2D coordinate system that associates the attribute values for the different attributes with respective portions of the 3D content. The process may further generate a single 2D image by combining the 2D data sets. The attribute values corresponding to the different attributes may be combined with the single 2D image. The process may further encode the single 2D image into a specialized format for transmission or storage.
