Abstract: A method is described for secure video processing. The method comprises storing an encrypted video stream (1) in a public stream buffer (2) in public memory accessible by a central processing unit (4) and allocating a private stream buffer (6) at a buffer location in private memory which is accessible by a decryption unit (10), wherein the private memory is not accessible for the central processing unit (4). The method then comprises decrypting the encrypted video stream (1) in the public stream buffer (2) to the private stream buffer (6) at the allocated buffer location (8) in private memory as an associated decrypted video stream (5); appending the allocated buffer location (8) to the public stream buffer (2); and configuring a video decoder unit (12) to read the decrypted video stream (5) from the private stream buffer (6) at the buffer location (8) for further processing.

Abstract: It is disclosed a video system comprising a video unit (101) and an external device (106) operable by the same user of the video unit (101). The video unit (101) comprises a video receiver (114) for receiving video signals and a decoder (115) operatively connected to the video receiver (114) to decode the received video signals, a control unit (113) configured to generate an interactive interface to be displayed on a first screen and to display one of the received video signals on the first screen, a receiving unit (112) operatively connected to the control unit (113) to receive a selection of the user when the interactive interface is displayed, a data unit (114) operatively connected to said control unit (113) for transmitting data to the external device (106). The external device (106) comprises a connection unit for connecting to an external network (105) and a screen for displaying data retrieved from the external network.

Abstract: A method for rendering a stereoscopic view, the method comprising the steps of defining a stereoscopic scene view (102) comprising representation of a scene object (112), receiving a left-eye texture (203) and a right-eye texture (206) for the scene object (112) and generating a left-eye scene view (101) comprising the left-eye texture applied to the representation of the scene object and the right-eye scene view (107) comprising a right-eye texture applied to the representation of the scene object. The method further comprises the steps of, prior to generating the left-eye scene view and the right-eye scene view, determining a value of the texture parallax (P1,P2) between the left-eye texture (203) and the right-eye texture (206) and offsetting the left-eye texture (203) and the right-eye texture (206) by a half of the value of the texture parallax (P1, P2) in opposite directions such as to provide an offset left-eye texture (601) and an offset right-eye texture (602) with a texture parallax equal to zero.

Abstract: The present invention relates to a method for combining images of a graphic user interface with a stereoscopic video content. The latter comprises at least a pair of video images intended respectively for a right and a left eye, while the graphic user interface comprises at least a pair of graphic images. The method comprises the steps of generating combined video images by blending each video image of said pair of video images with a respective graphic image of said pair of graphic images, so that the each combined video image comprises a first region (1 100) comprising only pixels from the video image and a second region (1200) wherein the blended video image appears in transparency behind the blended graphic image with a transparency that decreases according to a monotone law moving away from the first region (1100). A video processing unit adapted to implement the method is also disclosed.

Abstract: A method for generating, in a video signal receiver, an output signal for a display unit, comprising the steps of determining the display mode of the display unit, detecting the type of a video input signal received by the video signal receiver, converting the received video signal into an adapted output signal compatible with the display mode of the display unit, providing the adapted output signal to the display unit.
