Patent number: 9300927Abstract: There is provided a fingerprint (340) for a video stream (110) comprising a sequence of scenes (200a, 200b, 200c), wherein the fingerprint (340) includes information indicative of durations of the scenes (200a, 200b, 200c). The information indicative of the durations of the scenes (200a, 200b, 200c) is included in the fingerprint (340) in an order in which the scenes (200a, 200b, 200c) are included in the video stream (110). Moreover, each duration is optionally defined as a count of a number of video frames (260, 270) therein. The method is capable of generating a fingerprint which is susceptible to more simply and more efficiently synchronizing first and second data signals together.Type: GrantFiled: June 11, 2007Date of Patent: March 29, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Willem Franciscus Johannes Hoogenstraaten, Cornelis Wilhelmus Kwisthout

Patent number: 9234635Abstract: The invention relates to a lighting device and a method of manufacturing such a lighting device. The lighting device (1) comprises a first light emitting element (101) being optically coupled to a light guide (110) having an out-coupling surface (111) for illumination via the light guide. Further, the lighting device comprises a second light emitting element (102) dedicated for direct illumination from the lighting device. The invention is advantageous in that the lighting device provides both a decorative look and a functional illumination, and is still energy-efficient since the light emitted from the second light emitting element is directly emitted from the light emitting element without unnecessary energy-loss.Type: GrantFiled: December 9, 2011Date of Patent: January 12, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventor: Cornelis Wilhelmus Kwisthout

Patent number: 8371733Abstract: Disclosed are further improvements of AmbiLight Displaying Arrangement, a lighting or illumination system that has been introduced to enhance viewing experience. This is achieved by providing light sources (20) that create multiple colors next to at least one side of the screen (10) of the display device or arrangement, each of the multiple colors being 5 adapted to the video contents at a spatially corresponding region (50) of the screen (10). In one embodiment the lighting or illumination system can have an improved construction wherein a reflector (60) has a window section (65) enabling the light from the light sources (20) to be split into two. Half or more of the light is directed to the background (30) of the display device and half or less of the light is directed to the bezel diffuser (70), i.e. to the 10 front of the display device.Type: GrantFiled: December 21, 2007Date of Patent: February 12, 2013Assignee: TP Vision Holding B.V.Inventors: Willem Franciscus Johannes Hoogenstraaten, Cornelis Wilhelmus Kwisthout, Johannes Petrus Antonius Maria Van Asseldonk

Patent number: 8179400Abstract: A method for controlling an ambient lighting element including receiving a content signal, analyzing the content signal to determine a motion vector of an object (120A) depicted in the content signal, presenting the content signal on a display device, and adjusting an ambient lighting effect provided by the ambient lighting element as determined by the motion vector The presented content signal may be portioned into macro-blocks (110A) and sub-blocks (230). A motion vector of each sub-block (230) may be resolved into components that are parallel and perpendicular to an outside edge of the display device. An average color of each sub-block (230) depicted within a macro-block (110A) in proximity to an outside edge of the display device may be weighted by the motion vector of the corresponding sub-block (230) for determining an average color of the macro-block (110A). The average color of the macro-block (110A) may be used to adjust the ambient lighting element.Type: GrantFiled: February 26, 2007Date of Patent: May 15, 2012Assignee: Koninklijke Philips Electronics N.V.Inventor: Cornelis Wilhelmus Kwisthout

Publication number: 20120019722Abstract: A display apparatus comprises a display on which first video content of a video signal is presented. In addition, second video content is simultaneously presented e.g. superimposed on the first video content. A presentation processor (209) determines a first characteristic for the presentation of the first video content and a characteristics processor (211) determines a presentation characteristic for the second video content from the first characteristic. A transmitter (213) transmits the presentation characteristic to an external source of the second video content. A single device (401) may generate the video signal comprising both the first and second video content. In this case a characteristic of the overlaying is adjusted in response to the presentation characteristic. The invention may provide an advantageous adaptation of secondary (overlay) information to the current characteristics experienced when presenting primary video content.Type: ApplicationFiled: March 15, 2010Publication date: January 26, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Cornelis Wilhelmus Kwisthout, Guido Theodorus Gerardus Volleberg, Roel Reusens, Leendert Teunis Rozendaal, Mark Jozef Willem Mertens
