Abstract: A method for augmented reality (AR) remote rendering process performed by a remote rendering device. The method includes performing 3D scene compositing based on a live geometry information and an anchor information; receiving, from an AR device, a pose information; rendering 2D frame of the composited 3D scene based on the pose information; performing 2D frame processing on the rendered 2D frame; creating a first metadata associated with the 2D frame processing, a second metadata associated with the rendered 2D frame and a third metadata associated with AR frame compositing of the rendered 2D frame; and transmitting, to the AR device, the rendered 2D frame, the first metadata, the second metadata and the third metadata.

Abstract: The disclosure relates to a fifth generation (5G) communication system or a sixth generation (6G) communication system for supporting higher data rates beyond a fourth generation (4G) communication system such as long term evolution (LTE). The disclosure provides rendering of fisheye 360 degree video contents, including fisheye circular image videos. A method of a transmitting device is provided. The method includes transmitting, to a receiving device, a Session Description Protocol (SDP) offer message for negotiation of parameter associated with a fisheye image, and receiving, from the receiving device, a fisheye SDP answer message including second fisheye image related information generated based on first fisheye image related information included in the SDP offer message. wherein the first fisheye image related information includes first maximum packing information indicating a maximum number of fisheye images that is available to be packed into one stream.

Abstract: A method of accessing 3D media content based on perspective-based random access is provided. The method includes receiving the media content and metadata, wherein the metadata includes first information about a perspective and second information about at least one face onto which the 3D object is projected, and the at least one face is associated with the perspective, and performing the perspective-based random access for the media content based on the first information and the second information.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The disclosure relates to a method and device for providing an augmented reality (AR) service in a communication system. According to an embodiment of the disclosure, a method performed by a user equipment (UE) includes generating ambient environment information including at least one piece of information obtained based on an ambient environment of the UE; establishing a session for receiving an AR service description from an application server; receiving, from the application server, the AR service description including pipeline information indicating a transmission path related to the AR service and result information about at least one process requested by the UE; and transmitting the ambient environment information to the application server and receiving at least one media segment of an AR content from the application server based on the ambient environment information.
