摘要： A communication technique for merging, with an IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system is provided. The communication technique can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, and security and safety-related services, and the like) on the basis of a 5G communication technology and an IoT-related technology. A method for processing a 360-degree image is provided. The method includes determining a three-dimensional (3D) model for mapping a 360-degree image; determining a partition size for the 360-degree image; determining a rotational angle for each of the x, y, and z axes of the 360-degree image; determining an interpolation method to be applied when mapping the 360-degree image to a two-dimensional (2D) image; and converting the 360-degree image into the 2D image.

摘要： The disclosure relates to a 5th Generation (5G) or 6th Generation (6G) communication system for supporting a higher data transmission rate. The method of a first entity performing a media resource function (MRF) includes transmitting, to a second entity, a session description protocol (SDP) offer message for an SDP negotiation associated with a conference providing a plurality of 360-degree videos, and receiving, from the second entity, an SDP answer message. Wherein the SDP offer message includes a plurality of media descriptions for the plurality of 360-degree videos, and wherein, in case that a first 360-degree video of the plurality of 360-degree videos is originated from one of a plurality of sources at a conference location of the conference, a first media description for the first 360-degree video includes a content attribute for identifying a source from which the first 360-degree video is originated.
