Abstract: According to an embodiment of the present disclosure, there is provided a method of receiving a multimedia service, in which, by using user feedback information in a large-volume 6 degrees of freedom (6DoF) media transmission service using network-based media processing (NBMP), it is possible to reduce network traffic through efficient media transmission and a burden of rendering media content on a terminal. According to an embodiment of the present disclosure, a method of processing content includes receiving content regarding an object in a three-dimensional (3D) space, the content including media data and metadata, performing pre-rendering on the media data based on user information, and outputting pre-rendered data.

Abstract: The present disclosure relates to a communication apparatus and method for supporting a forward error correction scheme in a communication system. To this end, by means of a generation mode among a plurality of generation modes (ssbg_mode #0, #1, #2), a source symbol block having a plurality of source symbols is generated by using a source packet block having a plurality of source packets, and a repair symbol block for the generated source symbol block is generated by means of a forward error correction (FEC) scheme among a plurality of FEC schemes (FEC payload ID mode 0, FEC payload ID mode 1). A first FEC scheme (FEC payload ID mode 1) is applied to generate the repair symbol block, and in response to an occurrence of a discontinuity in packet sequence numbers, a repair packet may be generated to include length repair data and a repair FEC payload identifier (ID).

Abstract: Various embodiments of the present disclosure relate to a device and a method for processing point cloud data on the basis of PCC technology in a multimedia system. To this end, a bit stream according to point cloud compression may be generated, and the bit stream may be divided to generate access units by a plurality of type-specific data elements. The plurality of data elements may include at least one layer-specific shape data, at least one layer-specific texture data, auxiliary patch information, and occupancy information. The size of each of the plurality of access units may match a maximum transmission unit in a network.
