Abstract: A method for managing video data in a storage system (10), the video data comprising frames, and a storage system (10) configured to perform the method are described. The storage system (10) comprises a first input (11) configured to receive (1) one or more frames for storage. A storage more frames unit (12) stores (2) the one or more frames, whereas a unique identifier generator (13) associates (3) a unique identifier to each of the one or more frames. The storage system (10) further comprises a processor (14) configured to generate (4) a modified frame by processing one or more frames or to receive a modified frame generated externally. The unique identifier generator (13) associates (5) a derived unique identifier to such a modified frame, which comprises references to the unique identifiers of the one or more processed frames.
Abstract: An access point receives from a client a first nonce and a first cryptographic hash for the first nonce, the first cryptographic hash calculated using a first key derived from a second key, the second key input on the client or derived from a passphrase input on the client, derives first keys from each of a stored primary input and at least one stored secondary input valid at the deriving, the stored primary input and the at least one stored secondary input each being one of a second key and a passphrase, verifies the cryptographic hash using each derived first key to find a derived first key that checks the first cryptographic hash, generates a third key and a second cryptographic hash using the derived first key that checks the first cryptographic hash, and sends the third key and the second cryptographic hash to the client.

Abstract: A method for navigating through media content is described. The method (600) includes receiving (610) a media content stream, generating (620) a plurality of images associated with the media content stream after it is received, retrieving (630) information for a future media content stream, and providing (650) the information for the future media content stream along with the plurality of images for display along with the media content stream. The apparatus (300) includes an input signal receiver (302) that receives a media content stream, a video processor (310) that generates a plurality of images associated with the media content stream after it is received, a controller (314) retrieving information for a future media content stream that is available after the media content stream is received, and a display interface (315) providing the information for the future media content stream along with the plurality of images associated with the media content stream for display along with the media content stream.
Abstract: The present disclosure concerns a device for forming at least one focused beam in a near zone, from an electromagnetic wave incident on said device. Such device is remarkable in that it comprises at least one layer of a dielectric material comprising at least partially a first element, said first element having a first refractive index value, said first element comprising at least partially a second element, said second element having a second refractive index value greater than said first index value, and wherein said second element comprises at least a base surface, defined with respect to an arrival direction of said electromagnetic wave, and wherein said at least a base surface comprises at least two opposite edge line segments whose shape and associated base angles between said at least a base surface and a lateral surface of said second element, in a vertical plane with respect to said at least a base surface, control a shape of said at least one focused beam.
Abstract: In one embodiment of the disclosure, it is proposed a photolithography device for generating structure on a photoresist substrate, the photolithography device comprising a light illumination unit and a photomask. The photomask is remarkable in that it comprises at least one layer of dielectric material and a medium having a refractive index lower than that of said dielectric material, wherein a surface of said at least one layer of dielectric material has at least one abrupt change of level forming a step, and wherein at least a base and lateral part of said surface, with respect to said step and a propagation direction of an electromagnetic wave from said light illumination unit, is in contact with said medium.
Abstract: A method and apparatus for generating an extrapolated image from an existing film or video content, which can be displayed beyond the borders of the existing file or video content to increase viewer immersiveness, are provided. The present principles provide to generating the extrapolated image without salient objects included therein, that is, objects that may distract the viewer from the main image. Such an extrapolated image is generated by determining salient areas and generating the extrapolated image with lesser salient objects included in its place. Alternatively, salient objects can be detected in the extrapolated image and removed. Additionally, selected salient objects may be added to the extrapolated image.

Abstract: An augmented reality (AR) interactive system and method is provided. In one embodiment the systems comprises a head mounted user interface configured to receive user input, a processor configured to manage data based on user input, a camera and a display. The camera and the display are in processing communication with one another and the head mounted user interface via the processor. The processor is configured to determine a user's field of view and a center of the user's field of view based on output of a sensor and rendering images for output to the display. Each of the images include one or more objects and a plurality of signs each corresponding to a selectable object in the user's field of view. The rendering of images include altering a first display attribute of a given sign of the plurality of displayed signs based on determining that the user's field of view is centered on the given sign.

Abstract: The present disclosure relates to methods, apparatus and systems for automatically adapt the zoom coefficient of the camera of a system when running an augmented reality application. A pose estimation is performed for the camera which captures the real scene and the boundaries of the AR scene are calculated. According to the camera frustum and the boundaries, three-dimension rectangles are computes to determine a zoom coefficient that would optimize the seeing of the seen and the optimal position for the camera. The zoom is automatically optically or digitally adapted and the optimal position is indicated to the user by visual, audio or haptic means.

Abstract: A switch device for use in a gateway equipment and a gateway equipment comprising the switch device are suggested. The suggested switch comprises a Foreign Exchange Station (FXS) port configured to be connected to a telephone set, a Foreign Exchange Office (FXO) port connected to communicate analog voice signals with an external network, and a Voice over Internet Protocol (VOIP) unit configured to communicate digital data signals with the external network and enable a VOIP call using the digital data signals. The switch device comprises a switch configured to, when the gateway equipment is power down, connect the FXS port to the FXO port. The switch device also comprises a power unit configured to generate a work voltage from the analog voice signals at the FXO port to provide a power supply to the switch.
Abstract: The present disclosure is directed to an apparatus (300) and method (400, 600) for controlling a filter circuit (500) in a signal communication device (300). The apparatus (300) and method (400, 600) of the present disclosure receives (410) an indication of a plurality of channels used to transmit upstream communication signals in an upstream communication portion of a frequency range. Furthermore, the apparatus (300) and method (400, 600) of the present disclosure determines (420) a maximum frequency value among all frequencies used by the plurality of channels based on the indication and adjusts (430) a filter response in a filter circuit (500) used to separate the upstream communication signals from the downstream communication signals in a communication device (300) based on the determined uppermost frequency value.
