There is provided an information processing apparatus and an information processing method that can enhance the image quality while, at the same time, reducing increase in client's throughput. Image data of a plurality of projection directions is generated by projecting 3D data in a plurality of projection directions and converting the 3D data into two-dimensional data, and projection direction information indicating the projection direction of each piece of the image data is generated as projection metadata. Further, the projection direction information includes additional projection direction identification information that indicates that the image data has been generated by projection in additional projection directions. The present technology is applicable, for example, to a data generation apparatus that generates data for delivering a point cloud.

Systems and methods are provided for generating a trackable video-based product. One method comprises receiving a video comprising a plurality of frames from a video database; receiving product information associated with at least one product for sale from a product database; and receiving annotation data linking the received product information to at least one of the plurality of frames from a metadata database. The method may further comprise modifying a database to include a link between the at least one of the plurality of frames and the product information and generating an augmented video using the annotation data and the received video. The method may further comprise delivering the augmented video to a client device, such as a user device of a consumer, and responsive thereto receiving a communication related to the delivered video, the communication comprising data relating to an interaction with the video; comparing the data relating to the interaction with the link in the database to determine an associated product; and delivering information associated with the determined associated product to the client device.

A method for streaming a video. The method includes determining a total bitrate for a segment of a video to be received and streamed; predicting a viewpoint of a user for the segment; and determining bitrates for one or more tiles in the segment based on the determined total bitrate and the predicted viewpoint.

Image data having ultra-high definition at a high frame rate is processed to obtain image data, having a basic format, from which an image having high definition at a basic frame rate is to be obtained, image rate, having a first enhancement format, from which an image having high definition at a high frame rate is to be obtained, image data, having a second enhancement format, from which an image having ultra-high definition at a basic frame rate is to be obtained, and image data, having a third enhancement format, from which an image having ultra-high definition at a high frame rate is to be obtained. A basic video stream containing an encoded image data of the image data having the basic format, and a predetermined number of enhancement video streams containing the encoded image data of the image data having the first, second, and third enhancement formats are produced.

The present disclosure relates to a method and a device for generating and transmitting a media file containing three-dimensional (3D) video content. The present disclosure also relates to a method and a device for reconstructing and reproducing three-dimensional video content from a received media file. According to an aspect of an embodiment of the present disclosure, a method of generating a media file containing three-dimensional video content may include inserting, into a media data box in the media file, a plurality of components contained in a two-dimensional video frame in which the three-dimensional video content is compressed; inserting, into a metadata box in the media file, first tracks respectively corresponding to the components and a second track containing metadata; and inserting, into the second track, information about an entry point for each of the plurality of components.

In the present disclosure, methods, apparatuses, devices and media are provided for generating a video in a text mode in an information sharing application. In a method, a request is received for generating the video from a user of the information sharing application. An initial page is displayed for generating the video in the information sharing application, the initial page comprising an indication for entering text. Text input is obtained from the user in response to detection of a touch by the user in an area where the initial page locates. A video to be published in the application is generated based on the text input. In some examples, within the information sharing application, the user may directly generate a corresponding video based on a text input. In this way, a complexity of user operation may be reduced, and the user may be provided with richer publishing content.

The embodiments relate to a method comprising receiving as an input a volumetric video frame comprising volumetric video data (910); decomposing the volumetric video frame into one or more patches, wherein a patch comprises a volumetric video data component (920); packing several patches, where at least two patches of the several patches comprise a different volumetric video data component with respect to each other, into one video frame (930); generating a bitstream comprising an encoded video frame (940); signaling, in or along the bitstream, existence of encoded video frame containing patches of more than one different volumetric video data component (950); and transmitting the encoded bitstream to a storage for rendering (960). The embodiments also relate to a technical equipment for implementing the method.

An object is to efficiently display pieces of image data of some regions of interest (ROI) cut from a captured image on a display device. A reception device includes: a reception unit that receives a transmission signal in which image data of a predetermined number of regions of interest (ROIs) cut from a predetermined captured image is included in payload data and ROI information corresponding to a predetermined number of the ROIs is included in embedded data; and a processing unit that is configured to perform restoration processing of restoring the image data of the ROI so as to be displayable on a predetermined display device on the basis of the ROI information extracted from the embedded data.

There are provided a device and a method for generating timed media data, the timed media data comprising samples, the method comprising: obtaining samples of the time media data; creating tracks each comprising at least one of the obtained samples; and generating a presentation file comprising descriptive metadata associated with the created tracks, wherein the descriptive metadata comprise at least one track group box describing at least one group of created tracks, all the tracks belonging to a same group sharing properties, wherein a list of existing groups of tracks is declared in one single location in the presentation file, and wherein the properties shared by the tracks of a group of the list are declared at the same single location in the presentation file.

In one example, a method performed by a processing system including at least one processor includes acquiring a first item of media content from a user, where the first item of media content depicts a subject, acquiring a second item of media content, where the second item of media content depicts the subject, compositing the first item of media content and the second item of media content to create, within a metaverse of immersive content, an item of immersive content that depicts the subject, presenting the item of immersive content on a device operated by the user, and adapting the presenting of the item of immersive content in response to a choice made by the user.
