Provided in embodiments of the disclosure are a media processing method, device and system, and the computer-readable storage medium. The media processing method includes: in a media file, describing position information and/or position change information of a user; and processing the media file to determine a video to be played. As such, by describing position information and/or position change information of a user in the media file, the video frame can be adjusted in real time according to the position of the user, thereby improving the quality of viewing by the user and improving user experience.

Systems and methods are described for a media guidance application (e.g., implemented on a user device) that allows users to select any arbitrary position in a virtual reality environment from where to view the virtual reality content and changes a user's perspective based on the selected position.

One aspect of the invention is a method of providing video to attendees of a live concert. Video of different views of the live concert is captured. A plurality of video streams are provided to attendees of the live concert while the live concert is occurring. The plurality of digital video streams enable an attendee of the live concert to select which of the plurality of digital video streams to view using a portable digital device associated with that attendee such that the attendee may choose from among the different views of the live concert.

A content distribution node that distributes content to display devices which are arranged in a spaced apart sequence along a pathway of vehicles for display to passengers. The content distribution node receives from a mobile gateway node of a vehicle, through a Light Fidelity signal receiver circuit, a profile message containing profile information related to the vehicle. The content distribution node selects, from among content files available in a content repository, a set of video frames for distribution to the display devices based on the profile information. The content distribution node distributes different video frames among the set of video frames to different ones of the display devices with timing of the distribution that allows the video frames among the set to be displayed on respective ones of the display devices in the sequence before arrival of the vehicle within a field-of-view of at least one of the display devices.

An information processing apparatus (2000) includes a summarizing unit (2040) and a display control unit (2060). The summarizing unit (2040) obtains a video (30) generated by each of a plurality of cameras (10). Furthermore, the summarizing unit (2040) performs a summarizing process on the video (30) and generates summary information of the video (30). The display control unit (2060) causes a display system (20) to display the video (30). Here, the display control unit (2060) causes the display system (20) to display the summary information of the video (30) in response to that a change in a display state of the video (30) in the display system (20) satisfies a predetermined condition.

A content server and method supporting low-latency content streaming are proposed. The content server may include a communication unit and a controller. The communication unit may perform communication with a user terminal. The controller may calculate coordinates for a current user's location and camera pose and create a three-dimensional (3D) space by using terminal data including an image received from the user terminal upon detecting access of the user terminal. Also, the controller may position an object in the created 3D space, render a video reproduced from a user's viewpoint as a two-dimensional (2D) video, generate server data by segmenting the rendered 2D video, and transmit the generated server data to the user terminal.

A method and a system for virtual reality, augmented reality, mixed reality, or 360-degree Video environment is disclosed. The system receives Video Streams associated to audio and video scenes to be reproduced and Audio Streams associated to audio and video scenes to be reproduced. There are provided a Video decoder which decodes signal from the Video Stream for the representation of the audio and video scene; an Audio decoder which decodes signal from the Audio Stream for the representation of the audio and video scene to the user; and a region of interest processor deciding, based e.g. on the user's viewport, head orientation, movement data, or metadata, whether an Audio information message is to be reproduced. At the decision, the reproduction of the Audio information message is caused.

A server system includes a database for storing data, a memory device for storing data selected from the data in the database, and a processing device that selects data from the database, stores the selected data in the memory device, and transmits over a communication network an availability signal to a client, the availability signal including an identifier of the selected data and indicating that the selected data is stored in the memory device and is available to be accessed by the client.

Systems and methods described herein provide for rendering and quality monitoring of rendering of a 360-degree video, where the video has a plurality of representations with different levels of quality in different regions. In an exemplary method, a client device tracks a position of a viewport with respect to the 360-degree video and renders to the viewport a selected set of the representations. The client adaptively adds and removes representations from the selected set based on the viewport position. The client also measures and reports a viewport switching latency. In some embodiments, the latency for a viewport switch is a comparable-quality viewport switch latency that represents the time it takes after a viewport switch to return to a quality comparable to the pre-switch viewport quality.

In one embodiment, a method includes receiving a stored copy request indicating data and including a request identifier, scheduling publication of the data to an object store, and sending a subscription request indicating the data and the request identifier to the object store. In another embodiment, a method includes receiving a publication request indicating data to be copied, wherein the publication request is a recording request indicating a channel and a timespan, receiving one or more subscription requests for the data, receiving the data, and generating a copy of the data for each subscription request.
