  • Patent number: 12058190
    Abstract: A system and method is provided for performing lossless switching in a redundant multicast network. An exemplary method includes receiving a primary media stream and a redundant media stream over different forwarding network paths by network ports of a receiver communicatively coupled to an A/V device. Furthermore, the receiver outputs media data of the media streams to the A/V device to be presented thereon. In response to a control signal to switch the receiver to a new primary media stream, the method disconnected either the primary ort the redundant media streams from the respective network port of the receiver receiving that stream. Furthermore, the method includes controlling the disconnected network port to receive the new primary media stream and then outputting media data of the new primary media stream to the A/V device to be presented thereon.

  • Publication number: 20240087006
    Abstract: Disclosed is a method for sharing content on a decentralized platform comprising uploading content items by plurality of content creators; generating ownership non-fungible token (NFT) for each uploaded content item, wherein each generated NFT is owned by its respective content creator; calculating the price of each content item based on number and/or value of bids placed by one or more scouts for corresponding content item; transferring a share of ownership in ownership NFT from respective content owner to one or more scouts winning the bid; and automatically distributing payment received for licensed content item among corresponding NFT owners.

  • Publication number: 20220408155
    Abstract: Disclosed is a server arrangement for providing media content to a user device. The server arrangement is configured to identify a plurality of items of media content from at least one data source related to the service request; analyse the plurality of items of media content to determine values of pertinence indicators for each of the plurality of items of media content; determine a quality prediction score for each of the plurality of items of media content, wherein the quality prediction score for items of media content is determined based on values of pertinence indicators for the media content; provide a filtered set of items of media content to the user device, in response to the service request, wherein the set of items of media content comprises at least one item of media content having a quality prediction score higher than a predefined threshold.
