Patent number: 11734875Abstract: An apparatus comprises a receiver (301) for receiving an image representation of a scene. A determiner (305) determines viewer poses for a viewer with respect to a viewer coordinate system. An aligner (307) aligns a scene coordinate system with the viewer coordinate system by aligning a scene reference position with a viewer reference position in the viewer coordinate system. A renderer (303) renders view images for different viewer poses in response to the image representation and the alignment of the scene coordinate system with the viewer coordinate system. An offset processor (309) determines the viewer reference position in response to an alignment viewer pose where the viewer reference position is dependent on an orientation of the alignment viewer pose and has an offset with respect to a viewer eye position for the alignment viewer pose. The offset includes an offset component in a direction opposite to a view direction of the viewer eye position.Type: GrantFiled: January 19, 2020Date of Patent: August 22, 2023Assignee: Koninklijke Philips N.V.Inventors: Fons Bruls, Christiaan Varekamp, Bart Kroon

Patent number: 11671578Abstract: A three dimensional (3D) video signal is processed in a video device. The device has generating means for generating an output signal for transferring the video data via a high-speed digital interface like HDMI to a 3D display, which selectively generate a 3D display signal for displaying the 3D video data on a 3D display operative in a 3D mode, a 2D display signal for displaying 2D video data on the 3D display operative in a 2D mode, or a pseudo 2D display signal by including 2D video data in the output signal for displaying the 2D video data on the 3D display operative in the 3D mode. Processing means detects a request to display 2D video data on the 3D display, while the 3D display is operative in the 3D mode, and, in response to the detection, the generating means are set to generate the pseudo 2D display signal for maintaining the 3D mode of the 3D display.Type: GrantFiled: February 10, 2022Date of Patent: June 6, 2023Assignee: Koninklijke Philips N.V.Inventors: Philip Newton, Fons Bruls, Wiebe De Haan, Joop Talstra, Erik Moll

Publication number: 20070160301Abstract: The present invention provides a method for compressing the video stream with the spatial stratification, firstly, encoding said video stream after drop-sampling to obtain a base stream; then, decoding and rise-sampling said base stream to obtain a reconstructed stream; subtracting the reconstructed stream from said video stream to obtain a residual stream; next, carrying out the edge detection and analysis for said video stream to obtain the gain value of each pixel in the video stream; finally, multiplying said gain value by said residual stream and encoding the obtained result to obtain an enhanced stream. The invention further finely fractionizes the type of each pixel to obtain its corresponding more accurate gain value, thereby further decrease the number of the transmitted data and the transmitting bit rate required by the enhanced layer based on the premise that the quality of mages can be ensured.Type: ApplicationFiled: December 8, 2004Publication date: July 12, 2007Applicant: KONINKLIJKE PHILIPS ELECTRONIC, N.V.Inventors: Jin Wang, Fons Bruls, Gang Wang, Li Li

Publication number: 20070107036Abstract: This invention provides a method that when the disturbance of the bandwidth or the signal quality occurs during the digital program broadcasting, so that the broadcasting quality of the currently broadcast normal program is below a predetermined value, a prearranged program having a specific broadcasting quality, such as advertisements, will be inserted. The prearranged program may have an regular relation to the currently broadcast normal program, thereby the user would rather appreciate some program than suffer bad screen showing or wait until the program returns back to a good condition to be watched normally. This invention further provides a method for making statistics of the inserted prearranged program, said statistical information could be used for charging.Type: ApplicationFiled: November 25, 2004Publication date: May 10, 2007Inventors: Ningjiang Chen, Fons Bruls, Yongqin Zeng, Xin Chen

Patent number: 7116712Abstract: An apparatus and method for processing a multimedia digital bitstream is disclosed. The apparatus comprises a processing chain made up of a plurality of media processors. Each media processor processes a portion of the multimedia digital bitstream in real time. Each portion of the multimedia digital bitstream is split into a primary bitstream and a secondary bitstream. The primary bitstream is processed and merged with the unprocessed secondary bitstream. The parallel processing method of the present invention enables the processing chain to output a fully processed bitstream in real time. The processing chain may be used to transcode a high definition (HD) video bitstream in real time using a plurality of bitrate transcoder units.Type: GrantFiled: November 2, 2001Date of Patent: October 3, 2006Assignee: Koninklijke Philips Electronics, N.V.Inventors: Rob Vogelaar, Johan G.

Publication number: 20060123450Abstract: Disclosed is a method of creating video object units (VOBU) in high-definition DVD (HD-DVD) systems. HD enhanced data in the form of data packets are multiplexed and stored with standard-definition (SD) data in a VOBU. In the VOBU, the spa ce where the video pocket (V-PCK) and the for SD data related video packet (V-P CK-HD) for HD-enhanced data are stored is shortened as possible. This will increase the efficiency of a future enhanced DVD video player that supports the HD-DVD optical disc format to fetch, decode and synchronize the SD and HD enhanced data. Furthermore, the optical disc created in this kind of data storing has good backward compatibility.Type: ApplicationFiled: December 22, 2003Publication date: June 8, 2006Inventors: Gongming Wei, Bei Wang, Fons Bruls
