Patent number: 7679629Abstract: Systems and methods for filtering to comply with copy-protection regulations set forth for HDTV signals by the Motion Picture Association of America (“MPAA”) are presented. A copy-protection filter constrains the resolution of the HDTV signal when copy-protection bits are present in a video signal. The copy-protection filter may be placed in an analog data stream before the video signal is converted from a digital to an analog signal. A second copy-protection filter is optionally placed in a digital data stream. The copy-protection filter may be combined with other filters in a video encoder, or with a scaler before the input video data stream enters a compositor.Type: GrantFiled: August 15, 2003Date of Patent: March 16, 2010Assignee: Broadcom CorporationInventors: Darren Neuman, Patrick Law, Alek Movshovich, Chuck Monahan

Patent number: 7519232Abstract: A system and method that determines the strength of an edge in a video image using a gradient of the edge in a first direction and a gradient of the edge in a second direction. The system uses the gradient in the first direction and the gradient in the second direction to approximate a distance function to determine the strength of the edge. A programmable threshold may be used in the determination, where an edge is treated like it does not exist if the distance is less than the threshold. The distance function may be an approximation of the Cartesian distance function.Type: GrantFiled: September 21, 2004Date of Patent: April 14, 2009Assignee: Broadcom CorporationInventors: Darren Neuman, Patrick Law

Patent number: 7412096Abstract: A system and method that determines the direction of an edge in a video image using a gradient of the edge in a first direction and a gradient of the edge in a second direction. The system uses the sign of the product of the gradient in the first direction and the gradient in the second direction along with a ratio of multiples of the two gradients to determine the direction of the edge. The direction may correspond to an angle range, where the ratio of the gradients corresponds to a trigonometric function of the angle of the edge.Type: GrantFiled: September 21, 2004Date of Patent: August 12, 2008Assignee: Broadcom CorporationInventors: Darren Neuman, Patrick Law

Publication number: 20080129863Abstract: A system and method that produces a spatial average for interlaced video in a deinterlacer. The system detects edges in the video images and determines the angle at which the edges are oriented based on the gradient in the x-direction and the gradient in the y-direction. The direction of the edge is determined using the angle information of the edge. The system may also determine the strength of the edge. Based on the determined characteristics of the edge a filter may be selected to produce a spatial average of the edge in the image.Type: ApplicationFiled: February 11, 2008Publication date: June 5, 2008Inventors: Darren Neuman, Patrick Law

Publication number: 20080016254Abstract: Embodiments of a distributed memory controller system implemented on a single integrated circuit device are described. In one embodiment, a memory controller that provides an interconnection circuit between a first plurality of memory devices to a second plurality of memory clients includes a ring bus to route at least one of the memory request and data return signals between the memory clients and the memory devices. The ring bus is configured in a ring topography that is distributed across a portion of an integrated circuit device, resulting in a reduction in the maximum wiring density at the center of memory controller. The ring bus structure also reduces the overall number of interconnections as well as the number of storage elements, thus reducing the total area used by the memory controller.Type: ApplicationFiled: July 11, 2006Publication date: January 17, 2008Inventors: Warren F.

Publication number: 20080005038Abstract: A method and system automatically harmonizes access to a given software application program via different access devices. Through use of the method and system, a financial institution can provide access to a given application (such as, for example, automatic bill payment services) to customers using different access devices such web browsers, screen phones and personal computers. A single application program is all that needs to be written and maintained by the financial institution. Also, the method and system enables financial institutions to “leverage” existing programs because now the institution can automatically “project” its existing stock of program services unto new access devices—devices which may not have even existed at the time the program was created. By receiving information from the user via the user's access device, including information identifying the type of device being used and the application program the user wishes to access, the present invention solves these problems.Type: ApplicationFiled: June 19, 2007Publication date: January 3, 2008Inventors: Michael Grandcolas, Wendell Anthony, Patrick Law, Leslie Moss, Teresa Petach, Peter Tompkins

Publication number: 20070240037Abstract: Computer-implemented methods and systems for creating and managing website content involve, for example, providing a user at a computer terminal a data capture template for a user-selected content type, providing the user at the computer terminal presentation pages using content management tags, allowing the user at the computer terminal to author content using the data capture template, and allowing the user at the computer terminal to deploy the content to a server. Other aspects of the methods and systems for creating and managing website content include, for example, allowing the user to personalize content, allowing the user to embed dynamic content in the middle of static content, allowing the user to refresh the deployed content in real-time without impacting current existing user sessions on the server where content is being deployed.Type: ApplicationFiled: May 21, 2007Publication date: October 11, 2007Applicant: CITICORP DEVELOPMENT CENTER, INC.Inventors: France Law-How-Hung, Sam Shahdousti, Patrick Law, Anna Putnam, Peter Lomenzo

Publication number: 20070110230Abstract: Provided is an architecture (hardware implementation) for an authentication engine to increase the speed at which multi-loop and/or multi-round authentication algorithms may be performed on data packets transmitted over a computer network. Authentication engines in accordance with the present invention apply a variety of techniques that may include, in various applications, collapsing two multi-round authentication algorithm (e.g., SHA1 or MD5 or variants) processing rounds into one; reducing operational overhead by scheduling the additions required by a multi-round authentication algorithm in such a matter as to reduce the overall critical timing path (“hiding the ads”); and, for a multi-loop (e.g., HMAC) variant of a multi-round authentication algorithm, pipelining the inner and outer loops.Type: ApplicationFiled: January 8, 2007Publication date: May 17, 2007Applicant: Broadcom CorporationInventors: Mark Buer, Patrick Law, Zheng Qi

Publication number: 20060125825Abstract: A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. A relatively low chip-footprint, versatile texture environment (TEV) processing subsystem is implemented in a pipelined graphics system circulates computed color and alpha data over multiple texture blending/shading cycles (stages). The texture-environment subsystem combines per-vertex lighting, textures and constant (rasterized) colors to form computed pixel color prior to fogging and final pixel blending. Blending operations for color (RGB) and alpha components are independently processed by a single sub-blend unit that is reused over multiple processing stages to combine multiple textures.Type: ApplicationFiled: October 4, 2005Publication date: June 15, 2006Applicant: Nintendo Co., Ltd.Inventors: Patrick Law, Mark Leather, Matthew Komsthoeft
