Abstract: An apparatus for providing a 360 degree virtual reality broadcasting service uses an image acquired through a 3D virtual reality (VR) camera to transmit a 360 degree full image stream having first resolution and transmits an image stream of a view of interest (Vol) region having second resolution different from the first resolution according to a user selection mode and move information if the user selection mode and the movement information are received from a receiving apparatus.

Abstract: Provided is a method of supporting a random access of MPEG data, the method including: obtaining at least one access unit including media data coded through processing including an encapsulation and a packetization; generating at least one media processing unit (MPU) by grouping at least one access unit; determining an initialization flag indicating whether the at least one access unit includes all of data required for initialization of a decoding process, in the at least one MPU; and inserting the initialization flag into a header of the at least one MPU.

Abstract: A method of processing an immersive video includes classifying view images into a basic image and an additional image, performing pruning with respect to view images by referring to a result of classification, generating atlases based on a result of pruning, generating a merged atlas by merging the atlases into one atlas, and generating configuration information of the merged atlas.

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 are a method and a player for outputting an overlay that displays additional information on a 360-degree video. According to the present invention, an image processing method includes: decoding an overlay; and rendering the decoded overlay on a 360-degree video on the basis of overlay-related information. Here, the overlay-related information includes information indicating the number of the overlays and information indicating a unique identifier assigned to the overlay, and when multiple overlays are present, the identifiers assigned to the respective multiple overlays differ.
