It is possible to enable a reception side to easily recognize that metadata is inserted into an audio stream. A metafile including meta information for acquiring an audio stream into which metadata is inserted through a reception device is transmitted. The identification information indicating that the metadata is in into the audio stream is inserted into the metafile. At the reception side, it is possible to easily recognize that the metadata is inserted into the audio stream based on the identification information inserted into the metafile.

A method for streaming a 360 degree video over a communications network, wherein the video is streamed in a plurality of chunks, includes selecting a prediction window during which to predict a field of view within the video, the field of view is expected to be visible by a viewer at a time of playback of a next chunk of the video, wherein a duration of the prediction window is based on at least one condition within the communications network, selecting a machine learning algorithm to predict the field of view based on a head movement of the viewer, wherein the machine learning algorithm is selected based on the duration of the prediction window, predicting the field of view based on the head movement of the viewer and the machine learning algorithm, identifying a tile of the next chunk that corresponds to the field of view, and downloading the tile.

Systems and methods for reducing latency on a collaborative platform are provided. The collaborative platform involves a display, a moderator device, one or more member devices, and a receiver in communication with the display, the moderator device, and the one or more member devices. To reduce latency of the collaborative platform, the receiver generates an overlay image based on user input received from the display, as well as user type of the user input, generates an overlaid image based on the overlay image, and transmits the overlaid image for display, while a collaboration application generates new real image(s) based on the user input for display. The overlaid image generated may be indicative of actual user input as well as predicted user input using extrapolation and/or machine learning.

A visual enhancement engine is used to render a tile-based image generated on a user's device based on facial image movements within a video signal. The visual enhancements include orientation and size adjustments to the tile, based on a facial tracking algorithm. The enhanced image provides a more robust and realistic interactive video session in a multi-participant video conference environment.

The present disclosure provides an edge computing network, a data transmission method and apparatus, a device and a storage medium. The edge computing network includes: a first edge node configured to receive streaming media data sent by a first client, store the streaming media data onto a first storage resource, and store information of the first storage resource onto a second storage resource, both the first storage resource and the second storage resource being located in the edge computing network; and a second edge node configured to receive a request sent by a second client, acquire the information of the first storage resource from the second storage resource, acquire the streaming media data from the first storage resource based on the information of the first storage resource, and send the streaming media data to the second client.

An electronic device, computer program product, and method are provided that automatically focus on meaningful content in an image stream during an instruction-oriented video communication session. The electronic device communicatively connects the electronic device via a network to second electronic device(s) during a video communication session. A controller of the electronic device identifies a person and a writing surface within an image stream from a local image capturing device. In response to determining that the person is attending to the writing surface, the controller communicates to a video communication session a first portion of the image stream that focusses on the writing surface. In response to determining that the person is not attending to the writing surface, the controller communicates to the video communication session via the at least one network interface, a second portion of the image stream that does not focus on the writing surface.

A method and system for requesting information from a server are provided. The method may include sending, by a client to a server, an HTTP GET request to retrieve at least a portion of at least one derived data file, the at least one derived data file being dynamically generated by the server in response to the request using a data file virtualization policy and at least a portion of a data file. The data file virtualization policy and the data file may be stored in a storage accessible by the server, and the dynamic generation may comprise an aligned unbuffered direct read operation from the stored data file of a data size that is aligned to an integer multiple of the storage's block size. The at least the portion of the at least one derived data file may then be received by the client from the server.

The present subject matter relates to point cloud encoding and decoding methods and apparatuses. A point cloud file transmitted by a data source is received. The point cloud file comprises point cloud media tracks having the same point cloud content and point cloud media tracks having different frame rates. File encapsulation information of the point cloud media tracks are parsed to obtain frame rate indication information carried in the file encapsulation information. The frame rate indication information indicates frame rates of the point cloud media tracks. A point cloud media track with a designated frame rate is selected and decoded from the point cloud file according to the frame rate indication information carried in the file encapsulation information.

An electronic device, computer program product, and method are provided that autonomously mitigates degraded transmissions of an audio/image stream from an electronic device to a video communication session. The electronic device communicates at least one of an image stream and an audio stream to other second electronic device(s). In response to receiving an indication that the at least one of the image stream and the audio stream is degraded, a controller presents a transmission quality degraded report using at least one display device to prompt mitigation. The controller can configure the electronic device to mitigate the degraded at least one of the image stream and the audio stream by altering the at least one of the image stream and the audio stream to support transmission via a lower data rate. The electronic device communicates the altered at least one of the image stream and the audio stream to the session.

A method, computer program, and computer system is provided for media content preparation for 5G networks. A reverse address mapping process for 5G media streaming associated with a content preparation process is identified. A media content address is calculated based on the identified reverse address mapping process. A workflow is generated for the content preparation process based on the calculated media content address. 5G media streaming content preparation is performed according to the workflow of the content preparation process.
