The present disclosure relates to an image processing apparatus and method that enable linking between a 3D spatial region and an atlas tile group.

Link information is generated and signaled, in which the link information is stored in a file together with a bitstream of a point cloud expressing an object having a three-dimensional shape as a set of points, and the link information links a 3D spatial region of the point cloud with an atlas tile group. On the basis of the link information, the 3D spatial region and the atlas tile group that correspond to a desired three-dimensional space are selected. The present disclosure can be applied to, for example, an image processing apparatus, an information processing apparatus, an image processing method, an information processing method, or the like.

Systems and methods are described for modifying the content of a media content item. A a media content item is displayed on user equipment. A user reaction to one or more portions of the media content item is determined. The content of the media content item is modified based on the user reaction to one or more portions of the media content item.

A method performed by an electronic device for requesting tiles relating to a viewport of an ongoing omnidirectional video stream is provided. The ongoing omnidirectional video stream is provided by a server to be displayed to a user of the electronic device. The electronic device predicts for an impending time period, a future head gaze of the user in relation to a current head gaze of the user, based on: A current head gaze relative to a position of shoulders of the user, a limitation of the head gaze of the user bounded by the shoulders position of the user, and a current eye gaze and eye movements of the user. The electronic device then sends a request to the server. The request requests tiles relating to the viewport for the impending time period, selected based on the predicted future head gaze of the user.

The embodiments relate to a method including generating a bitstream defining a presentation including an omnidirectional visual media content; encoding into the bitstream a parameter to indicate viewport-control options for viewing the presentation, wherein the viewport-control options includes options controllable by a receiving device and options not-controllable by the receiving device and sending the bitstream to the receiver device; receiving one of the indicated viewport-control options from the receiver device as a response; streaming the presentation to the receiver device; when the response has included an indication on a viewport-control controllable by the receiving device, the method also includes receiving information on viewport definitions from the receiver device during streaming of the presentation and adapting the presentation accordingly; when the response has included an indication on a viewport-control not- controllable by the receiving device, the presentation is streamed to the receiver device according to the viewport-control specified in the response.

A method is provided for displaying an immersive video content according to eye movement of a viewer includes the steps of detecting, using an eye tracking device, a field of view of at least one eye of the viewer, transmitting eye tracking coordinates from the detected field of view to an eye tracking processor, identifying a region on a video display corresponding to the transmitted eye tracking processor, adapting the immersive video content from a video storage device at a first resolution for a first portion of the immersive video content and a second resolution for a second portion of the immersive video content, the first resolution being higher than the second resolution, displaying the first portion of the immersive video content on the video display within a zone, and displaying the second portion of the immersive video content on the video display outside of the zone.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. Telepresence is provided through over-the-air (OTA) virtual reality (VR) broadcast streams.

A secondary content such as an advertisement may be inserted based on users' interests in 360 degree video streaming. Users may have different interests and may watch different areas within a 360 degree video. The information about area(s) of 360 degree scenes that users watch the most may be used to select an ad(s) relevant to their interests. One or more secondary content viewports may be defined within a 360 degree video frame. Secondary content viewport parameter(s) may be tracked. For example, statistics of the user's head orientation for some time leading to tile presentation of the ad(s) may be collected. Secondary content may be determined based on the tracked secondary content viewport parameters).

A computer system including a server having a processor and a memory, the memory having a video database and a music database, the video database storing at least one video file having a plurality of video file markers, and the music database storing at least one music file having a plurality of music file markers, wherein the server receives and decodes encoded data from computer readable code, identifies and retrieves from the music database a music file based on the decoded data, synchronizes the retrieved music file with one of the video files by aligning the video file markers of the video file with the music file markers for the retrieved music file to produce a synchronized video-music file, and transmits the synchronized video-music file to a display, wherein the video file markers are generated for each video file and the music file markers are generated for each music file.

The present invention relates to a device and method for transmitting and receiving a broadcasting signal including a subtitle service. An embodiment of the present invention provides a broadcasting signal transmission method comprising the steps of: generating a broadcasting signal including video data and subtitle data; and transmitting the generated broadcasting signal. According to an embodiment of the present invention, a transmission stream providing a digital broadcasting subtitle service using XML subtitles can be transmitted.

The present disclosure relates to an image processing device and an image processing method for generating a celestial sphere image such that the pixels near the poles of the sphere are kept from increasing in density when the image is mapped to the sphere surface.

An encoder encodes, with respect to an omnidirectional image generated by equidistant cylindrical projection to include a top image, a middle image, and a bottom image in a vertical direction, the middle image into an encoded stream at a high resolution, and the top image and the bottom image into encoded streams at a resolution lower than the high resolution. This disclosure is applicable to image display systems, among others.
