20080212947 | Device For Handling Data Items That Can Be Rendered To A User - A device (DVR) handles data items that can be rendered to a user. Such a device may be, for example, a digital video recorder. The device (DVR) comprises a network interface (NWIC, NWIM) that couples the device (DVR) to a network, which comprises other devices. A content analysis initiator (ECF) within the device (DVR) detects that another device, which forms part of the network, comprises a content analyzer. The content analysis initiator (ECF) causes the content analyzer (AVCA) of the other device to be applied to a data item (AVF). | 09-04-2008 |
20080256576 | Method and Apparatus for Detecting Content Item Boundaries - The invention relates to a method of identifying a boundary ( | 10-16-2008 |
20080267290 | Coding Method Applied to Multimedia Data - The invention relates to a coding method applied to digital video data available in the form of a video stream consisting of consecutive frames divided into macroblocks. These frames are coded in the form of at least I-frames, coded independently, P-frames, predicted from at least a previous I- or P-frame, and B-frames, bidirectionally predicted from at least two frames between which they are disposed. According to the invention, the coding method comprises the following steps:

20090016441 | CODING METHOD AND CORRESPONDING CODED SIGNAL - The invention relates to a coding method applied to digital video data available in the form of a video stream consisting of consecutive frames. These frames, divided into macroblocks, include at least I-frames, independently coded, or P-frames, temporally disposed between said I-frames and predicted from at least a previous I- or P-frame, or B-frames, temporally disposed between an I-frame and a P-frame, or between two P-frames, and bidirectionally predicted from at least these two frames between which they are disposed, said predictions of P- and B-frames being performed by means of a weighted prediction with unequal amount of prediction from the past and the future. According to the invention, this coding method comprises the following steps: a structuring step, provided for capturing coding parameters characterizing the said weighted prediction; a computing step, for delivering statistics related to said parameters; an analyzing step for determining a change of preference regarding the direction of prediction; a step provided for detecting the occurrences of gradual scene changes; a step provided for generating description data of said occurrences; and a step for encoding the description data thus obtained and the original digital video data. | 01-15-2009 |
20090052537 | METHOD AND DEVICE FOR PROCESSING CODED VIDEO DATA - The present invention relates to a method of processing digital coded video data available in the form of a video stream consisting of consecutive frames divided into slices. The frames include at least I-frames, coded without any reference to other frames, P-frames, temporally disposed between said I-frames and predicted from at least a previous I- or P-frame, and B-frames, temporally disposed between an I-frame and a P-frame, or between two P-frames, and bidirectionally predicted from at least these two frames between which they are disposed. The processing method comprises the steps of determining for each slice of the current frame related slice coding parameters and parameters related to spatial relationships between the regions that are coded in each slice, collecting said parameters for all the successive slices of the current frame, for delivering statistics related to said parameters, analyzing said statistics for determining regions of interest (ROIs) in said current frame, and enabling a selective use of the coded data, targeted on the regions of interest thus determined. | 02-26-2009 |
20100026784 | METHOD AND SYSTEM TO CONVERT 2D VIDEO INTO 3D VIDEO - 2D/3D video conversion using a method for providing an estimation of visual depth for a video sequence, the method comprises an audio scene classification ( | 02-04-2010 |
20100185617 | CONTENT AUGMENTATION FOR PERSONAL RECORDINGS - A content augmentation process for personal recordings involves a service center (SC). The service center (SC) collects personal recordings from various different users via a network so as to constitute a database (DB) of personal recordings. The service center (SC) identifies personal recordings within the database (DB) that concern a particular scene and that are mutually complementary so as to form a selection of personal recordings (FSRR) for content augmentation purposes. The service center (SC) applies a content augmentation process (AUGP) to the selection of personal recordings (FSRR) so as to obtain an enhanced representation (CA). | 07-22-2010 |
