A video rendering method is provided. The method includes acquiring a first video which is to be rendered and a material video for rendering the first video, wherein the material video is obtained by splicing and combining at least two video effects, and each of the video effects comprises a plurality of material pictures. The method further includes disassembling a plurality of material blocks from the material video, each of the material blocks being obtained by sequentially arranging a plurality of material pictures belonging to a same video effect, determining target positions of the material blocks in a video frame of the first video, and acquiring a second video by superimposing the material blocks on the target position of the video frame to complete video rendering.

The invention relates to a server for providing a graphical user interface to a client over a communication network. The graphical user interface comprises a graphical user interface element, the graphical user interface element being formed by an element shape and an element text, the element shape being represented by element shape data, the element text being represented by element text data. The server comprises an encoder configured to encode the element shape data into video data, a detector configured to detect a change associated with the graphical user interface element within the graphical user interface, and a communication interface configured to separately transmit the video data and the element text data over the communication network, the element text data being transmitted upon detection of the change associated with the graphical user interface element for providing the graphical user interface to the client.

There is provided an information processing apparatus, a reproduction processing apparatus, and an information processing method that improve data transmission efficiency. A preprocessing unit (102) generates, as scene configuration information indicating a configuration of a scene of 6DoF content including a three-dimensional object in a three-dimensional space, dynamic scene configuration information that changes over time and static scene configuration information that does not change over time, the static scene configuration information being scene configuration information different from the dynamic scene configuration information.

There are disclosed various methods, apparatuses and computer program products for viewing volume signalling of volumetric video. In accordance with an embodiment of a method information of a viewing volume appropriate for viewing a volumetric video is obtained. The viewing volume is examined to determine what geometrical shapes describe the viewing volume. One or more geometrical shapes determined for describing the viewing volume are selected, wherein signalling information for the selected one or more geometrical shapes is constructed.

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to embodiment, the method includes receiving, from a server, an SD based on URL information obtained from an AR/MR application, processing the SD, configuring at least one media buffer pipeline for a media object of a scene, based on the processed SD, and establishing transport sessions for components of the media object.

A media playback system for presenting to a user a composition of a plurality of media streams. It has a media selection component configured to receive a scenario dataset, to receive user input for selecting viewing times defining segments of media and composition selections, and to output a list of segments of media from the scenario dataset that are authorized to be viewed by the user. The system has a playback control component configured to retrieve from media storage at least the segments of media from the output list of segments, to decode the segments of media, and to compile composition instructions. The system has a media playback component configured to receive the rendered media and the composition instructions.

Media content data of an object is received. Whether a first parameter indicated by a first description of the object in an acoustic scene and a second parameter indicated by a second description of the object in a visual scene are inconsistent is determined. Based on the first parameter indicated by the first description of the object in the acoustic scene and the second parameter indicated by the second description of the object in the visual scene being inconsistent, one of the first description of the object in the acoustic scene and the second description of the object in the visual scene is modified based on another one of the first description and the second description that is not modified, wherein the modified one of the first description and the second description is consistent with the other one of the first description and the second description that is not modified.

The present disclosure has a configuration in which a distributor who performs a separate distribution that is different from this live content, or a viewer who views this separate distribution can participate in a virtual space and express intent or participate in visual recognition through the commitment of a virtual item.

Aspects of the subject disclosure may include, for example, a method that includes obtaining, by a processing system including a processor, video frames over a network; the processing system uses a machine learning algorithm to identify in each frame a first region comprising a natural image and a second region comprising a synthetic graphic image. The processing system separates the natural image from the synthetic graphic image to generate a natural video and a graphics video, encodes the natural video, and processes the graphics video to generate instructions for rendering graphic images at a client system. The client system performs a decoding procedure for the encoded video, a rendering procedure for client-side graphics in accordance with the instructions, and a compositing procedure to obtain a presentable video stream including the natural image and a client-side graphic corresponding to the synthetic graphic image. Other embodiments are disclosed.

Methods and systems for deploying a video analytics system include determining one or more applications for a security system in an environment, including one or more constraints. Each functional module in a directed graph representation of one or more applications is profiled to generate one or more configurations for each functional module. The nodes of each graph representation represent functional modules of the respective application, and repeated module configurations are skipped. Resource usage for each of the one or more applications is estimated using the one or more configurations of each functional module and the one or more constraints. The one or more applications are deployed in the environment.
