Publication number: 20050262026Abstract: Systems and methods for securely authorising an on-line transaction, e.g. involving a micro-payment, between a customer browser and merchant server without the need for special software installed on the customer computer or a SSL connection to the merchant server. The authorisation method involves a double redirection instruction: the initial transaction request is redirected via the customer web browser to a service provider arranged to authenticate the customer, from where the authenticated instruction is further redirected via the customer web browser to a merchant site to complete the transaction. Information identifying the merchant, merchandise, etc. is included in the redirection instruction, and may be encrypted or encoded e.g. using a hash function to prevent tampering. To authorise an authenticated instruction, a cookie containing transaction identification data may be returned to the merchant web server along with the authenticated instruction.Type: ApplicationFiled: May 12, 2005Publication date: November 24, 2005Inventor: Daniel Watkins

Patent number: 6968286Abstract: A profile-based system is described for verifying the functionality of a device design. In one embodiment, the system includes a profile generation module, a coverage measurement module, and a pattern generation module. The profile generation module operates from a rule set that represents the design specification and any applicable standards, and a profile mode that specifies “interesting” aspects of test patterns for device design verification. The profile generation module determines an ordered set of variable values that specify a test pattern, and produces a profile that intelligibly describes the interesting aspects of the test pattern. The coverage measurement module analyzes the profile to determine coverage, and the analysis results may be operated on by the profile generation module to determine a profile for an improved test pattern. The pattern generation module converts the profile into a test pattern having the interesting aspects specified in the profile.Type: GrantFiled: July 28, 1999Date of Patent: November 22, 2005Assignee: LSI Logic CorporationInventor: Daniel Watkins

Patent number: 6901207Abstract: An audio/visual (A/V) device, such as a DVD player, assists a user in finding desired programming from among DVD programs, conventional broadcast television (TV) programs and World Wide Web transmitted programs. The programs contain close caption (CC) and A/V content. The A/V device captures and stores the CC and/or A/V content either for current or later manual use by the user or concurrent automatic searching for desired program content or information. Text-based searching is performed on the CC content for a match with user-specified textual search criteria. The audio context is searched for either a change that indicates a change in programming or a match with user-specified audio search criteria. A video still image is captured from the video content for manual viewing or automatic comparison to a desired image. The A/V device also presents the information, including the A/V content, captured CC content and search results, on either a conventional TV or higher resolution progressive monitor.Type: GrantFiled: March 30, 2000Date of Patent: May 31, 2005Assignee: LSI Logic CorporationInventor: Daniel Watkins

Patent number: 6728477Abstract: A DVD player or computer with a DVD drive simultaneously presents multiple angles of video on a display. DVD standards provide for formatting and storing video that was filmed from more than one angle. Desired angles are selected, and the DVD player multiplexes between each angle of the playback to decode video frames for each selected angle. The frames for each angle being played back are filtered down to a size that fits into a fragment of the display. Each of the filtered frames are assembled into a single frame that can be presented on the display to simultaneously playback each angle.Type: GrantFiled: December 28, 1999Date of Patent: April 27, 2004Assignee: LSI Logic CorporationInventor: Daniel Watkins

Patent number: 6507672Abstract: An improved multimedia encoder having features advantageous for use in a computer system. These features provide for the reduction of bandwidth and storage requirements, the enhancement of noise immunity, the evening of computational loading, and the use of multimedia drives for general purpose data storage. In one embodiment, the encoder receives image data representing a sequence of video frames and display text data representing a sequence of text fields to be overlaid on the sequence of video frames. The multimedia encoder produces a compressed video frame only for each subsequent video frame which is different from the current video frame. After each video frame is compressed, it becomes the current frame. The multimedia encoder provides error correction encoding to enhance noise immunity, and performs interframe compression using a dynamic search area to even out computational loading.Type: GrantFiled: September 30, 1997Date of Patent: January 14, 2003Assignee: LSI Logic CorporationInventors: Daniel Watkins, Gregg Dierke
