Patent number: 7202912Abstract: A TV system that uses a single pixmap across multiple video rasters having different raster sizes. In general, the TV system uses at least two sets of headers to select different portions of a single pixmap to be displayed based on different raster sizes. Specifically, each of the headers in a header set points to a pixel line to select number of pixels for that pixel line. The number of the headers in a header set determines the height of the pixmap and the pixel number selection by a set of headers determines the width of the pixmap. In response to different displaying modes, the TV system selectively invokes one of the two header sets to select different portions of the single pixmap. By doing so, a single pixmap can be used across multiple video rasters having different raster sizes.Type: GrantFiled: April 30, 2001Date of Patent: April 10, 2007Assignee: Thomson LicensingInventors: Charu Aneja, Aaron Hal Dinwiddie

Publication number: 20040263691Abstract: A video signal processing system for processing a video data VIN and graphic data D&mgr;P includes a filter unit, which receives the video data VIN. The filter unit filters the video data VIN to convert the video data VIN into video pictures formated with a different number of columns and/or lines, and provides a filtered video signal indicative thereof. The filter unit buffers individual pixels and/or lines in a first memory device. A second memory device receives and stores the graphic data D&mgr;P and the filtered video signal and provides stored signals indicative thereof. A third memory device is connected to the second memory, and stores data received from the second memory device. A mixing unit receives and mixes the stored graphic data and the stored filtered video data to provide a video output signal VOUT.Type: ApplicationFiled: January 26, 2004Publication date: December 30, 2004Inventors: Bernd Broghammer, Karl Buehler, Guenther Huber, Michael Maier, Gerd Mauthe, Thomas Sagcob, Juergen Vogel

Publication number: 20040233333Abstract: An adaptive pixel-based blending method and system of a video processing system including steps of acquiring a first pixel value in accordance with a first index value, acquiring a first blending factor in accordance with the parts of the first pixel value, calculating a second blending factor in accordance with the first blending factor, and generating a overlapped and blended image in accordance with the blending factors and the pixel values of the source images. Thus, multiple source images can be overlapped and blended in a flexible way.Type: ApplicationFiled: May 24, 2004Publication date: November 25, 2004Applicant: VIA TECHNOLOGIES, INC.Inventors: An-Te Chiu, Roger Lin, Denzel Wang

Patent number: 6812934Abstract: An image processing method at the time of character display in an image apparatus having a section for super-imposing character display on an ordinary dynamic picture image. In the method, the level of “color depth” of the dynamic picture image is automatically controlled at the time of character display to thereby make it easy to see character display. Specifically, when character display is effected in monochrome, the dynamic picture image is displayed in a color other than monochrome. When character display is effected in a color other than monochrome, the dynamic picture image is displayed in monochrome.Type: GrantFiled: October 30, 1996Date of Patent: November 2, 2004Assignee: Funai Electric Co., Ltd.Inventor: Noboru Yoshida

Patent number: 6803968Abstract: An image synthesizing system is provided that can prevent image deterioration resulting from synthesis applied to a predictive image to be used for the next frame. The image synthesizing system decodes and synthesizes a main frame and a sub-image compressed in different modes. The image synthesizing system includes a main image frame buffer 122, an alpha blending section 133, and an image synthesis and display 140. The main image frame buffer 122 stores a main image to be referred to in the next frame decoding process. The alpha blending section 133 alpha-blends a main image from the main image frame buffer with a decoded sub-image to produce a translucent composite image. The image synthesis and display 140 superimposes the translucent composite image on the main image.Type: GrantFiled: April 11, 2000Date of Patent: October 12, 2004Assignee: NEC CorporationInventor: Kohji Numata

Publication number: 20040189872Abstract: Embodiments of the present invention provide a method and apparatus for maintaining smooth video transition between distinct applications. Preferably, the apparatus implementing the present invention includes a processor, a secondary memory and a system memory. In providing a smooth transition between two applications, the apparatus and method provides synchronization of the video and graphics components while transitioning from a first application to a second application. If there is no video component in either application, no action is needed to provide a smooth transition between applications, and when only the first application includes a video component, the video component need only be turned off for smooth transition between the applications to occur.Type: ApplicationFiled: March 27, 2003Publication date: September 30, 2004Applicants: Sony Corporation, Sony Electronics Inc.Inventors: James Amendolagine, Ted Dunn

Publication number: 20040177383Abstract: Graphics metadata is embedded in an input video signal at a first system, to form a processed video signal which is distributed to a plurality of second systems, typically cable or broadcast systems. Each individual second system can edit the metadata and insert graphics into the video based on the edited metadata so as to form a final signal for broadcast or other distribution to viewers. Thus, each second system can provide a final signal with an appearance consistent with the brand identity of that individual second system. The metadata facilitates storage and retrieval of the video.Type: ApplicationFiled: January 26, 2004Publication date: September 9, 2004Applicant: Chyron CorporationInventors: James Martinolich, William D.
