Provided are a computer program, a method, and a server in which a possibility that a load on display control increases is reduced, compared to the related art. According to an exemplary embodiment of such a configuration, first data relevant to a first position in a virtual space in which a first avatar manipulated by using a first terminal of a first user exists is acquired, whether or not a first condition is satisfied is determined, second data is received in a case where it is determined that the first condition is satisfied, control data for controlling a display unit of the first terminal such that at least the virtual object is displayed on the display unit of the first terminal is decided on the basis of the second data, and the display unit is controlled on the basis of the control data.

A media data preparation device adapted to receive media data, including at least one processor, and at least one non-transitory memory having computer program code stored thereon for execution by the at least one processor, the computer program code including instructions to receive a set of metadata that is based on at least one spatial coordinate, where the set of metadata is associated with the media data, and determine a representation of the media data in a virtual reality space based on the set of metadata

A computer-implemented method is disclosed. The method includes: receiving video data for a live video stream; identifying a product that is displayed in a video frame of the live video stream; obtaining identifying information for a viewer of the live video stream; determining a product variant preference for the viewer; obtaining a graphical representation of the product variant; and providing modified video data of the live video stream based on presenting the graphical representation of the product variant as overlay content for the live video stream. Related apparatuses and computer-readable media are also disclosed.

An example method performed by a processing system includes retrieving a digital model of a media element from a database storing a plurality of media elements, wherein the media element is to be inserted into a scene of an audiovisual media, rendering the media element in the scene of the audiovisual media, based on the digital model of the media element and on metadata associated with the digital model to produce a rendered media element, wherein the metadata describes a characteristic of the media element and a limit on the characteristic, and inserting the rendered media element into the scene of the audiovisual media.

According to a first aspect of this specification, there is described a computer-implemented method of tagging video frames. The method comprises generating, using a frame tagging model, a tag for each of a plurality of frames of an animation sequence. The frame tagging model comprises: a first neural network portion configured to process, for each frame of the plurality of frames, a plurality of features associated with the frame and generate an encoded representation for the frame. The frame tagging model further comprises a second neural network portion configured to receive input comprising the encoded representations of each frame and generate output indicative of a tag for each of the plurality of frames.

This disclosure relates to a virtual object control method. The method includes: displaying, by an electronic device, a first live streaming resource, the first live streaming resource including at least one selectable virtual object and at least one virtual object controlled by an anchor user; transmitting a control request when receiving a selection instruction for a target virtual object in the at least one selectable virtual object, the control request being for requesting to control the target virtual object; and controlling, in response to a control instruction for the target virtual object, the target virtual object to perform a target operation. With the foregoing method, viewer users can participate in live streaming when watching the live streaming, thereby improving the level of participation of the viewer users, and increasing interaction between the viewer users and the anchor user.

A video distribution system according to this disclosure is a video distribution system that distributes a video including an animation of a character object generated based on a movement of a distribution user and comprises one or a plurality of computer processors. The one or plurality of computer processors provide (i) a distribution portion, (ii) a display device, (iii) a determination portion. If the determination portion determines that a first object is being displayed within a predetermined distance from a second object, the object display device changes the first object and the second object to a third object and displays the third object.

A computer-implemented method for predictively downloading volumetric data may include (i) identifying an augmented reality device that (a) downloads volumetric data files representing pre-rendered three-dimensional segments of physical space within an augmented reality environment and (b) displays the augmented reality environment for viewing by a user, (ii) determining, based at least in part on a position of the user within the augmented reality environment, an expected physical space within the augmented reality environment that the user is predicted to view via the augmented reality device, and (iii) preemptively downloading, to the augmented reality device, a volumetric data file representing a pre-rendered three-dimensional segment of the expected physical space. Various other methods, systems, and computer-readable media are also disclosed.

Provided are a method and device for providing interactive virtual reality content capable of increasing user immersion by naturally connecting an idle image to a branched image. The method includes providing an idle image including options, wherein an actor in the idle image performs a standby operation, while the actor performs the standby operation, receiving a user selection for an option, providing a connection image, and providing a corresponding branched image according to the selection of the user, wherein a portion of the actor in the connection image is processed by computer graphics, and the actor performs a connection operation so that a first posture of the actor at a time point at which the selection is received is smoothly connected to a second posture of the actor at a start time point of the branched image.
