Abstract: A computer-implemented method for determining whether a video frame is of a 3D TB type (Top-Bottom) or a 3D LR type (Left-Right) frame, characterized in that it comprises the steps of: receiving a video frame (100); extracting at least three portions (121-124) of the frame, each portion belonging to a distinct quarter of the frame (100, 120) and being positioned at the same fragment of the quarter; calculating color histograms for each portion (121-124); comparing the color histograms of at least two different pairs of portions; generating a frame type indicator based on the result of comparison of the color histograms.

Abstract: One object of the invention is a display matrix controller configured to drive a display matrix (206, 308) to display frames of a source video signal, the controller comprising an input interface (203, 204) configured to provide for each frame to be displayed a frame difference information, specifying changed pixels, whose values change between a frame to be displayed and a currently displayed frame, a brightness equalizer (210) configured control the display of the frame such as to equalize the level of viewer perception of brightness to a predetermined level for each frame to be displayed depending on the frame difference information, and a matrix driving circuit (205, 307) configured to receive the frame difference information and to drive the display matrix (206, 308) to display the frame to be displayed by redrawing only the changed pixels

Abstract: One object of the invention is a digital video signal comprising a sequence of frames, wherein each video frame in the sequence differs with respect to the previous frame in the sequence by a number of pixels which is not higher than a predetermined pixels maximum threshold amount.

Abstract: The present invention relates to a method for coding a multiview video stream (100) comprising a plurality of images (104, 105, 106) corresponding to single views of a scene (100) in a fixed time instant. Said method comprises the steps of: dividing each of the images (104, 105, 106) in a plurality of slices; coding (502, 611) each slice; generating a multiview video stream (100) comprising a plurality of separate video streams (101, 102, 103). Each of the separate video streams (101, 102, 103) comprises: a set of the coded slices (401), first information (107a) adapted to define the position of the slices (401) in the images (104, 105, 106) and second information (107b) adapted to identify at least one video stream (101, 103) of the multiview video stream (100), wherein the identified video stream (101, 103) comprises at least one slice (404, 405) that, in the scene (100), is adjacent to a slice of the set (401).

Abstract: A method for controlling shutter glasses in synchronization with a video signal, comprising the steps of receiving a shutter glasses driving signal, the signal indicating the opening and closing time of shutter glasses, receiving a L/R side selection signal, the signal indicating the left or the right eye for which the a video frame of the video signal is displayed, opening or closing the left of right shutter glass according to the value of shutter glasses driving signal and the L/R side selection signal, wherein the method further comprises the steps of monitoring a screen programming signal at a display unit on which the video signal is to be displayed and processing the screen programming signal to generate the shutter glasses driving signal.

Abstract: A user interface for selecting and controlling a plurality of parameters of a device comprises a touch-sensitive apparatus (100) with a touch-sensitive area (101) and a controller (107). The touch-sensitive area (101) has a closed-loop shape limited at outside by an outer closed curve (105) and at inside by an inner closed curve (106) and capable to receive a touch input, whereas the controller (107) is connected to the touch-sensitive apparatus (100) and configured to detect a starting point (102) of the touch input, detect a touch hold duration at the starting point (102), in case of a touch hold duration not shorter than the activation time, determine a parameter associated with the starting point (102), in case of a hold duration shorter than the activation time, determine a previously controlled parameter, and control the determined parameter while the touch input moves along a control path (103). In addition, the control is sensitive to movement direction.

Abstract: A method for controlling a value of a parameter of an application executed on a device comprising a touch-sensitive input apparatus with a touch-sensitive area comprises the steps of defining a region map specifying within the touch-sensitive area a plurality of parameter control regions that have assigned a parameter change direction, receiving from the touch-sensitive input apparatus a touch start event specifying a touch starting position within the touch-sensitive area, monitoring the touch-sensitive input apparatus to receive a touch position change or a touch end event, upon detection of a touch position change setting a parameter change value according to the position change direction, upon detection of a touch end event before detection of a touch position change setting a parameter change value according to the parameter change direction specified for the parameter control region to which the touch starting position belongs and providing the parameter change value to the application.
