20100205317 | TRANSMISSION, RECEPTION AND SYNCHRONISATION OF TWO DATA STREAMS - In digital mobile broadcast systems, data streams audio and video are sent independently. As this means that both streams may arrive out of sync, they need to be synchronised for reproduction upon reception. For this, the relation between timestamps of both streams should be known. For broadcast, this is difficult because the information is usually not directly available upon the first reception of broadcasted streams and it cannot be send upon playback request. Therefore, the invention proposes to reset counters for generating timestamps upon the start of transmission of the broadcast. The incremental rate of the timestamps can be send on beforehand, as this information usually remains constant over a longer period in time. The invention provides methods for transmission, reception and synchronisation. | 08-12-2010 |
20110074909 | VIDEO TELEPHONY - A method of recording a video telephony call, the method comprising: setting up a call between a first terminal ( | 03-31-2011 |
20120250768 | VIDEO DECODING SWITCHABLE BETWEEN TWO MODES - Video decoder apparatus and method, for decoding a motion-compensated transform-coded video stream. The apparatus has: a first mode in which it is operable to decode the video stream at a first resolution, and wherein a motion-compensation step of the decoding is performed in the image-domain. It also has a second mode in which it is operable to decode the video stream at a second resolution, and wherein at least one motion-compensation step is performed in the transform-domain. The decoder is adapted to switch between the two modes while decoding the video stream. | 10-04-2012 |
20130129326 | VIDEO PLAYER - A method for down sampling data comprising the steps of down-sampling the data; and carrying out a motion compensation step on the down-sampled data which motion compensation step is carried out in the frequency domain, further comprising the step of transforming the data back to the spatial domain after the step of motion compensation has been performed. | 05-23-2013 |
20130182944 | 2D TO 3D IMAGE CONVERSION - A method (and system) of processing image data in which a depth map is processed to derive a modified depth map by analysing luminance and/or chrominance information in respect of the set of pixels of the image data. The depth map is modified using a function which correlates depth with pixel height in the pixellated image and which has a different correlation between depth and pixel height for different luminance and/or chrominance values. | 07-18-2013 |
20150026575 | NAVIGATING WITHIN A MEDIA ITEM - A method and apparatus for user-controlled navigation within a media item comprising a sequence of elements. The method comprises: defining a line or curve for controlling the navigation; defining a transfer function that associates a plurality of positions along the line or curve with respective elements of the sequence; detecting an input operation by the user, wherein the input operation selects one of the plurality of positions; determining the element of the sequence that corresponds to the user-selected position, according to the defined transfer function; and navigating within the media item to the determined element, wherein the transfer function is a nonlinear one-to-one mapping between the positions along the line or curve and the elements of the sequence. | 01-22-2015 |
20150163520 | APPARATUS AND METHOD FOR DECODING COMPRESSED VIDEO - A method and apparatus for decoding a compressed video is disclosed. The method comprises scrambling the compressed video, to produce a scrambled compressed video; delivering the scrambled compressed video to a decoder, for decoding the scrambled compressed video to produce a scrambled decompressed video; receiving from the decoder the scrambled decompressed video; and descrambling the scrambled decompressed video, to produce a descrambled decompressed video. | 06-11-2015 |
20150189130 | METHOD FOR VIDEO RECORDING AND EDITING ASSISTANT - A method for a video recording and editing application analyses the audio and video during the process of video recording using a smart device such as a smartphone or tablet. The method provides feedback to the user during the video recording to improve user performance and reduce video and audio user errors. The method includes the option of automatic skipping or editing of video segments that suffer from user errors during playback. | 07-02-2015 |
