Abstract: Disclosed herein is an immersive video processing method. The immersive video processing method includes: determining a priority order of pruning for source videos; extracting patches from the source videos based on the priority order of pruning; generating at least one atlas based on the extracted patches; and encoding metadata. Herein, the metadata may include first threshold information that becomes a criterion for distinguishing between a valid pixel and an invalid pixel in the atlas video.

Abstract: A method and apparatus for generating frames to apply error correction to data including a plurality of consecutive data groups are provided. Upon receiving input of an n-th data group consisting of a plurality of priority groups with different priority levels, the number of first code rate frames, which is the number of frames in the n-th data group for which a first code rate is used, is calculated based on the number of first code rate bits calculated based on the ratio of the length of data in an (n−1)-th data group for which the first code rate is used. The number of second code rate frames, which is the number of frames in the n-th data group for which the second code rate is used, is calculated based on the number of second code rate bits calculated based on the number of first code rate bits. Frames for error correction are generated based on the number of first code rate frames and the number of second code rate frames.

Abstract: A method of producing an immersive video comprises decoding an atlas, parsing a flag for the atlas, and producing a viewport image using the atlas. The flag may indicate whether the viewport image is capable of being completely produced through the atlas, and, according to a value of the flag, when the viewport image is produced, it may be determined whether an additional atlas is used in addition to the atlas.

Abstract: Disclosed herein is an immersive video processing method. The immersive video processing method includes: determining a priority order of pruning for source videos; extracting patches from the source videos based on the priority order of pruning; generating at least one atlas based on the extracted patches; and encoding metadata. Herein, a first flag indicating whether or not an atlas includes a patch including information on an entire region of a first source video may be encoded into the metadata.

Abstract: Disclosed is a method of transmitting, by a transmission device, broadcast signals in a frequency-shared terrestrial broadcast system. The method includes generating the broadcast signals including pilot signals arranged at a physical layer frame based on a group identification (ID) defined according to a broadcast service, and transmitting the generated broadcast signals to a reception device, wherein the positions of the pilot signals arranged at the physical layer frame are different by group IDs.
