METHOD AND APPARATUS FOR SHARED VIEWING OF MEDIA CONTENT
In systems and methods for enhancing group watch experiences, a first user's reaction is detected using multiple sensors, e.g., at least one camera and a microphone, and may be combined with context information to determine an action to perform at user equipment devices of other users participating in the group watch to convey the first user's reaction. Images from the at least one camera can be used to determine a portion of the screen to which the user's reaction is directed and/or another user to whom the reaction is directed. The reaction may be conveyed using one or more of an audio effect, a visual effect, haptic effect or text, e.g., to highlight the determined portion or user, display an icon and/or output an audio or video clip. A signal for providing haptic feedback may be transmitted to the user equipment device of the determined user.
Device and method for visually displaying speaker's voice in 360-degree video
An electronic device is disclosed. In addition, various embodiments identified through the specification are possible. The electronic device includes a display, a processor, and a memory storing instructions that, when executed by the processor, cause the processor to display, when a video supporting a plurality of orientation regions is played, a screen of a first orientation region among the plurality of orientation regions and a first text corresponding to a voice of a first speaker in the screen, and display, in response to a user input of selecting a voice of a second speaker located in a second orientation region, a screen of the second orientation region.

Use of hierarchical video and image coding for telepresence
A medical telepresence system comprising: an interface to receive a plurality of data feeds from a live medical procedure, at least one data feed comprising a video signal capturing the live medical procedure; a hierarchical encoder to encode the plurality of data feeds using a first tier-based hierarchical data coding scheme, wherein encoded data from the hierarchical encoder is decodable by a first set of computing devices for viewing, the first set of computing devices being communicatively coupled to the hierarchical encoder using a first network connection; a transcoder to convert from the first tier-based hierarchical data coding scheme to a second tier-based hierarchical data coding scheme, wherein encoded data from the transcoder is receivable by a second set of computing devices for viewing, the second set of computing devices being communicatively coupled to the transcoder using a second network connection, the second network connection being of a lower quality than the first network connection; and a recorder to store the output of the hierarchical encoder as a set of tier-based files for later retrieval, wherein each of the set of tier-based files represent different levels of quality.
Method and apparatus for transmitting video content using edge computing service
An example method, performed by an edge data network, of transmitting video content includes: obtaining first bearing information from an electronic device connected to the edge data network; determining second predicted bearing information based on the first bearing information; determining a second predicted partial image corresponding to the second predicted bearing information; transmitting, to the electronic device, a second predicted frame generated by encoding the second predicted partial image; obtaining, from the electronic device, second bearing information corresponding to a second partial image; comparing the second predicted bearing information to the obtained second bearing information; generating, based on a result of the comparing, a compensation frame using at least two of a first partial image corresponding to the first bearing information, the second predicted partial image, or the second partial image corresponding to the second bearing information; and transmitting the generated compensation frame to the electronic device based on the result of the comparing.
Foveation-based image encoding and decoding
An encoding method and a decoding method. The encoding method includes generating curved image by creating projection of visual scene onto inner surface of imaginary 3D geometric shape that is curved in at least one dimension; dividing curved image into input portion and plurality of input rings; encoding input portion and input rings into first planar image and second planar image, respectively, such that input portion is stored into first planar image, and input rings are packed into corresponding rows of second planar image; and communicating, to display apparatus, first and second planar images and information indicative of sizes of input portion and input rings.
VIDEO PROCESSING DEVICE AND MANIFEST FILE FOR VIDEO STREAMING
One aspect of this disclosure relates a video processing device comprising a processor for processing a manifest file for video streaming for a user. The manifest file comprises at least a plurality of positions defined for a scene that are associated with pre-rendered omnidirectional or volumetric video segments stored on a server system. The manifest file may also contain a plurality of resource locators for retrieving omnidirectional or volumetric video segments from the server system. Each resource locator may be associated with a position defined for the scene. The video processing device may be configured to associate a position of the user with a first position for the scene in the manifest file to retrieve a first omnidirectional or volumetric video segment associated with the first position using a first resource locator from the manifest file.
METHOD, DEVICE, AND COMPUTER PROGRAM FOR IMPROVING ENCAPSULATION OF MEDIA CONTENT
According to embodiments, the invention provides a method for encapsulating partitioned timed media data comprising timed samples, comprising in turn subsamples, the timed samples being grouped into groups, the method comprising: obtaining spatial tracks, each spatial track comprising at least one subsample of a first timed sample and one corresponding subsample of the other timed samples, the corresponding subsamples being located at the same spatial position in its own timed sample as the at least one subsample; creating a base track referencing at least some of the spatial tracks, the base track comprising reconstruction instructions, each of the reconstruction instructions being associated with a group of timed samples, enabling generating a portion of a bit-stream from sub-samples of spatial tracks, that belong to a same group of timed samples; and independently encapsulating each of the tracks in a least one media file.
