    摘要： The disclosure provide methods and content consumption devices that enable a scene, for example a 360° scene, that is larger (i.e. has more pixels in at least one dimension) than a display format of the content consumption device to be displayed. Constituent scene views are received individually by the content consumption device, for example as broadcasts, and are combined, for example stitched together, at the content consumption device to output a part of the scene that fits in the display format. The part of the scene (and hence the required constituent streams) to be displayed are determined by a signal, for example a navigational input from a user, enabling the user to navigate in the scene.

    摘要： In order to allow an access to the Internet, and therefore to a remote server, for a device having no connection with an Internet gateway, there is proposed a method to transmit a message from a first device to a remote server, the first device having no connection with the remote server, said method comprising:



    detecting a second device by the first device,
    establishing a communication channel between the first and the second device,
    transferring the message from the first to the second device, said message comprising an address of the remote server,
    transferring, by the second device, the message to the remote server using the remote server address contained in the message.

    摘要： The disclosure relates to a method of obtaining a cryptographic key in a chipset (1). An initial configuration message may be generated using a physical unclonable function (hereinafter: PUF) (22) of the chipset (1). Said PUF (22) may generate a predetermined value when using the initial configuration message as input to the PUF (22). The initial configuration message may be transmitted to a client access server (31). An altered configuration message may be received from the client access server (31), wherein the altered configuration message is generated by the client access server (31) based on the initial configuration message. The cryptographic key may be obtained from the PUF (22) using the altered configuration message as input to the PUF (22).

    摘要： Techniques and systems are provided for processing user interface content. For example, a server computer can receive a user interface event corresponding to a user interface of a device (e.g., a client device, another server computer, or other device). An application associated with the user interface event can be determined, and an interface model 5 can be generated using the application associated with the user interface event. The interface model defines state information for one or more graphic objects of the user interface. The state information results from the user interface event. The server computer can send the interface model to the device, which enables the device to render the user interface.

    摘要： A method of displaying content items, for example message items in a messaging application or service, is disclosed. The method comprises receiving encrypted content items in a chronological sequence; decrypting the content items; causing display of a display sequence, in order of the chronological sequence, of a respective place holder in place of each of the decrypted content items, and, in response to a user input, causing display of the respective content item in place of one or more of the place holders. Each place holder has an appearance of a scrambled version of the respective content item. The display sequence may be contiguous in received items or sent content items may be interleaved with received content items in the display sequence, in which case sent content items may be displayed with place holders in the same way as received items. A corresponding system and corresponding computer readable medium or media are also disclosed.

    摘要： Example embodiments provide systems and methods for managing intelligent content queuing from a secondary device for content delivery to a primary device. A content queuing system on the secondary device generates and displays a playlist interface on the secondary device. A selection of a content item to be added to a playlist is received. The content queuing system determines that addition of the content item causes a live content item to overlap with an on-demand content item on the playlist. As a result, the content queuing system creates at least two segments for the on-demand content item. The live content item is positioned between the first and a second segment on the playlist. The first segment is scheduled to end at a start time of the live content item and the second segment is scheduled to begin at an ending time of the live content item.
