In certain embodiments, one aspect provides a method of securely distributing multi-tier multimedia contents on the Internet, using Non-Fungible Token (NFT) Blockchain and comprising the steps of: signal processing data splitting phase, converting an original multimedia file into multiple data portions; access control encryption phase, converting each of the multiple data portions into an encrypted data portion and uploading the encrypted data portion to a storage cloud; access control storage phase, storing the encrypted data portion on the storage cloud; access control decryption phase, downloading the encrypted data portion from the storage cloud and reconstructing each of the encrypted data portions into each of said multiple data portions; and signal processing data merging phase, reconstructing appropriate multimedia data content depending on a user's tier level.

Methods for synchronizing a client application user interface (UI) state of content of a client application on a client device corresponding with a host application on a host device are presented, the method including: receiving an update on the host application; transmitting a request for remote notification to the client device to synchronize the UI state of content of the client application responsive to receiving the event; displaying a notification corresponding with the request for remote notification on the client device indicating content is available to the client device; selecting the notification; launching the client application on the client device; transmitting a synchronizing request by the client device to the host device; enabling a synchronization mode of the host application; determining a host application UI state; transmitting content data associated with the UI state of the host application to the client device; and displaying the client application UI state based on the content data from the host device.

Some embodiments relate to a method including obtaining information of available quality features of a sender device for providing omnidirectional visual media content; selecting one or more of the available quality features; and providing an indication of the selected one or more of the available quality features. There is also provided a method including obtaining information of available quality features of a receiver device for processing omnidirectional visual media content; providing an indication of the available quality features; receiving from a sender device indication of available quality features of the sender device among the available quality features of the receiver device; selecting one of the quality features, which are available both in the sender device and in the receiver device; and providing an indication of the selected quality feature.

Methods and apparatus for just-in-time streaming media. Existing content delivery networks are optimized for providing mass media to many consumers. This delivery model is poorly suited to user-specific content. Exemplary embodiments of the present disclosure create a program instance that can service a client's media requests from their archival data. In one specific implementation, the archival data is stored segments that are ready for streaming; a content server may provide either a consolidated file or a media “quasi-stream” from the same storage object(s). The quasi-stream supports progressive playback (media playback as it is being downloaded.) The program instance provides the client device the illusion of a static file system, however client requested access to HTTP file downloads are provided in packets that are transmuxed/transcoded from archival data. The various solutions described herein directly address a problem that is unique to providing access to client-specific data archives anytime, anywhere.

Packaging media for optimizing immersive media distribution of a media steam performed by at least one processor, is provided, including: receiving immersive media data for an immersive presentation; acquiring asset information associated with media assets corresponding to a set of scenes included in the immersive media data for the immersive presentation; analyzing characteristics of the media assets based on the asset information, the characteristics comprising an asset type associated with a respective media asset and a frequency that indicates a number of times the respective media asset is used among the set of scenes included in the immersive presentation; ordering the media assets in a sequence based on the asset type and the frequency associated with each of the media assets; and streaming the immersive media data for the immersive presentation based on the ordered sequence of the media assets.

A plurality of videos associated with a plurality of video resolutions may be received. A minimum bitrate may be identified for each of the video resolutions based on a first bitrate point associated with the videos where a quality of the videos at a first video resolution that is upscaled to a second video resolution is better than a quality of the videos at the second video resolution at bitrates below the first bitrate point. Furthermore, a maximum bitrate may be identified for each of the video resolutions based on a second bitrate point where the rate of change of the quality of the videos is below a threshold value. The identified minimum bitrates and the maximum bitrates may be assigned to the video resolutions.

An apparatus, method, and computer-readable recording medium perform client configuration of a managed device in a wireless network. A client device retrieves capabilities data from an Internet-based cloud server, builds a user interface (UI) based upon the user defined capabilities data and managed service defined capabilities data, sends a data request to the managed device, receives managed device state data from the managed device, sends command to update the managed device, and when the update of the managed device is complete, instructs managed device to send current user defined capabilities data and managed service defined capabilities data to the Internet-based cloud server.

Correlated quality-of-experience (QoE) and latency measures are generated at a plurality of monitoring points along a multimedia delivery chain including multiple video operations. At each of the plurality of monitoring points, an absolute QoE measure defined on a human perceptual quality scale for media content is computed, and one or more of content extraction or feature extraction on the media content are performed. To a common middleware from each of the plurality of monitoring points, the respective QoE measure and results of the one or more of content extraction or feature extraction are transmitted. Computing and updating an absolute QoE measure for each of the plurality of monitoring points is performed. Computing and updating latencies between multiple monitoring points at the middleware using the results from each of the plurality of monitoring points is also performed.
