There is included a method and apparatus comprising computer code configured to cause a processor or processors to perform providing a media presentation description (MPD) event and media segments of video content to be streamed to a client, controlling the client to provide a user interface based on the MPD event and comprising a plurality of selection choices and interactive data for each of the selection choices, and updating MPD data based on at least one selection from the selection choices through the user interface.

A system is provided for publishing a disparate live media output stream manifest that includes media segments corresponding to key events. A live production and playout system of disparate sub-systems is synchronized to a reference clock. A timecode from the reference clock is used as a reference time to log content related to key events that occur within the live production and playout system. A live event logging system is synchronized to the reference clock same as the live production and playout system. Based on location of the live event logging system, a time offset is introduced to compensate for a delay. When delay is variable, the reference clock is decoded from a live input stream to associate each key event with a corresponding timecode. Based on a programming schedule comprising the key events that occurred in the live input stream, the disparate live media output stream manifest is published.

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.

Methods, devices and stream are disclosed to encode and decode a scene (such as a point cloud) in the context of a patch-based transmission of a volumetric video content. Attributes of points of the scene are projected onto patches. Every point has a geometry attribute. For other attributes, like transparency of displacement attribute, some points may have no value. According to the present principles, each attribute is encoded in a different atlas with its own layout. This allow to save pixel rate in memory of the renderer.

Systems and methods are described herein for streaming during unavailability of a content server. Upon determining that there are conditions indicating buffering issues during delivery of a media asset, a server determines a first group of devices suitable for receiving the media asset from the server and sharing the media asset on a peer-to-peer network. Then, the server determines a second group of devices suitable for receiving the media asset on a peer-to-peer network from a first group device. The server then determines groupings within which to share and receive the media asset. Next, the server transmits instructions to the devices in the first group to maintain in buffer and share certain portions of the media asset with the second group devices within their grouping. Finally, the server updates information detailing the media asset portions the devices are maintaining in buffer and sharing.

Aspects of the subject disclosure may include, for example, a system for indicating a program boundary in an adaptive bitrate media stream, where the system includes a memory and a processor that performs operations including generating multiple transcoded media output streams of different bit rates from an input linear media stream, fragmenting the multiple transcoded media output streams into chunks, detecting a program boundary in the input linear media stream, and supplying a program change indicator in a manifest file for implementing program change features in mobile communication devices. Other embodiments are disclosed.

An encoder for use with video data, first supplemental data, second supplemental data, and a display device. The encoder includes: a memory; and a processor configured to execute instructions stored on the memory to cause the encoder to: generate modified video data based on an incorporation of the first supplemental data into the video data such that the supplemental video will be displayed at a predetermined location when the modified video is displayed on the display device; generate metadata associated with the predetermined location; generate an encoded transport stream including the modified video data, the metadata and the second supplemental data; and transmit the encoded transport stream to the display device so as to enable the display device to decode the encoded transport stream and display the modified video and the second supplemental video such that the second supplemental video is not displayed at the predetermined location.

Methods and systems of inserting image files into a container are described herein. One method includes overseeing a submission of images to containers, retrieving a job of inserting images into the container, and inserting images into the container by, for each of the plurality of images: (i) reading and analyzing source data including the image; (ii) opening the container, which includes records, where the image will be stored; (iii) determining whether the source data is valid to be entered into a record; (iv) responsive to a determination that the source of data is valid, preparing metadata; (v) writing the record into the container; and (vi) marking a status flag/mark of the record as being updated while writing the record into the container.

The present invention concerns a method for generating media files from video sequences, the method comprising by a server: obtaining from the video sequences, video data composed of a plurality of samples; generating a video track based on the obtained video data, each video track comprises samples of a video sequence, and the video track is associated with descriptive metadata, the descriptive metadata comprises: a spatial information related to one or more samples of the associated video track; and a composition information for organizing generated video tracks to get a full picture when displayed by a client; and generating media files including the generated video tracks.

Methods, devices and stream are disclosed to encode and decode a volumetric content. At the encoding, the space of the volumetric content is divided in distinct sectors according to at least two different sectorizations. One atlas is generated for each sectorization or a single atlas is generated encoding all the sectorizations. At the decoding, a sectorization is selected according to the current direction and field of view, according to user's gaze navigation and according to prediction of the upcoming pose of the virtual camera controlled by the user. Sectors are selected according the selected sectorization and the current direction and field of view and only patches encoded in regions of the atlas associated with these sectors are accessed to generate the viewport image representative of the content seen from the current point of view.
