A method and a device for configuring a time block structure are provided. A method performed by a controller in a communication system supporting ranging is provided. The method includes generating a ranging control message (RCM) including configuration information on a hyper block structure, and transmitting, to at least one controlee, the ranging control message, wherein the hyper block structure has a repeated pattern of a hyper block which is a group of ranging blocks.

Method and device for configuring time block structure for UWB communication

A method for operating a first ultra-wideband (UWB) device according to an embodiment of the disclosure may include: transmitting, in a first slot within a ranging round, a ranging control message for UWB communication; receiving a first packet transmitted by a second UWB device in a second slot within the ranging round based on the ranging control message; and receiving a second packet transmitted by a third UWB device in the second slot within the ranging round based on the ranging control message.

Ultra-wideband device for transmitting/receiving multiple packets and method for operating same

Provided is a method for transmitting metadata for omnidirectional content including a plurality of viewpoints. The method comprises identifying the metadata for the omnidirectional content including the plurality of viewpoints; and transmitting the identified metadata, wherein the metadata includes information about an identifier (ID) of a viewpoint group including at least one viewpoint of the plurality of viewpoints, and wherein the at least one viewpoint in the viewpoint group shares a common reference coordinate system.

Method and device for transmitting information on three-dimensional content including multiple view points

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).

Apparatus and method for communication in broadcast system

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.

Device and method for processing data in multimedia system

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.
