Patent number: 8358376Abstract: This invention relates to a device and a method of generating a first and a second fingerprint (102,104) usable for synchronization of at least two signals (101,103) and corresponding method and device for synchronizing two or more signals. A fingerprint pair is generated on the basis of a segment of a first signal e.g. an audio signal and of a segment of a second signal e.g. a video signal at each synchronization time point. The generated fingerprint pair(s) are stored in a database (203) and communicated or distributed to a synchronization device (303). During synchronization, fingerprint(s) of the audio signal and fingerprint(s) of the video signal to be synchronized are generated and matched against fingerprints in the database. When a match is found, the fingerprints also determine the synchronization time point, which is used to synchronize the two signals. In this way, a simple, reliable and efficient way of synchronizing at least two signals is obtained.Type: GrantFiled: February 9, 2011Date of Patent: January 22, 2013Assignee: Gracenote, Inc.Inventors: Job Cornelis Oostveen, David K.

Publication number: 20060242398Abstract: A computer system includes a system memory (SM) and a non-volatile memory (NVM). The computer system is arranged to copy at least a part of the system state, stored in the system memory during a clean boot-up procedure, into the non-volatile memory (209, 329). During subsequent start-ups of the computer system, the system state is copied from the non-volatile memory into the system memory (205, 305), resulting in a significantly faster system start-up. In case the configuration of the computer system has changed, the complete boot-up procedure is executed again and the new system state is copied into the non-volatile memory, overwriting the previously stored system state.Type: ApplicationFiled: May 25, 2004Publication date: October 26, 2006Inventors: Wilhelmus Franciscus Fontijn, Adrianus Denissen, Robert Jochemsen, Nicolaas Lambert

Publication number: 20060190776Abstract: This invention relates to a device and a method of relating one or more trigger actions with a multimedia signal and corresponding method and device for detecting one or more trigger actions in a multimedia signal. One fingerprint is generated on the basis of a segment of the multimedia signal at each trigger time point. The generated fingerprint(s) is stored in a database and communicated to playback devices. During playback fingerprints of the multimedia signal are generated and matched against fingerprints in the database. When a match is found, associated trigger actions is retrieved. The trigger time point is determined as a time point near or at a segment of the multimedia signal that caused a fingerprint to match. In this way, a simple and reliable way of detecting trigger markers for trigger actions is enabled without modifying the multimedia signal.Type: ApplicationFiled: July 5, 2004Publication date: August 24, 2006Inventors: Job Oostveen, Warner Rudolph Ten Kate, Adrianus Denissen, David Roberts

Publication number: 20060146597Abstract: The present invention provides a special structure of magnetic elements, e.g. MRAM elements (10, 11), as a security device (30) for IC's containing magnetic memory cells. The structure may comprise a combination of two or more associated magnetic elements (10, 11) with pre-set anti-parallel magnetization directions. By determining the polarisation directions of the magnetic elements, exposure to an external magnetic field can be detected. Inverse polarisation directions indicate a normal situation, aligned polarisation directions indicate that the MRAM-array has been exposed to an external field. In this way it can be detected whether it has been tried to erase or alter the data stored in the MRAM in an illegal way. The IC can regularly check the resistance of the security system during operation. Upon detection of a field exposure, the IC can erase all MRAM data, or can reset itself or block its functioning.Type: ApplicationFiled: December 15, 2003Publication date: July 6, 2006Inventors: Kars-Michiel Lenssen, Adrianus Denissen, Nicolaas Lambert

Publication number: 20060053268Abstract: When booting a personal computer, it needs to find instructions immediately to tell it what to run to start up the personal computer. These it finds within the so-called basic input/output system (BIOS) program. Usually the BIOS program is stored in a separate location, for example a ROM. It is usually shadowed into system memory (SM) to speed up its operation. The copying of the BIOS program to system memory (SM), amongst others, causes the boot process to be a relatively slow process. In the present invention, the system memory (SM) comprises a persistent system memory (PSM) and the BIOS program is stored in the persistent system memory (PSM). Furthermore, selected information used by the BIOS program is stored in persistent system memory (PSM) as well. As a result, the speed of booting the personal computer is significantly increased.Type: ApplicationFiled: October 8, 2003Publication date: March 9, 2006Inventors: Wihelmus Franciscus Fontijn, Nicolaas Lambert, Robert Jochemsen, Adrianus Denissen

Publication number: 20060041731Abstract: The present invention relates to a method for managing memory space of a persistent-memory device and to a memory management device. The memory management method of the invention comprises a step of allocating (S14) at least one first part of said memory space to a file system (74) upon request from said file system (74) or from an application (70). The method and the device of the present invention enable a dynamical allocation of persistent-memory space to a file system. This way, the memory space of a persistent memory is effectively used also for write-caching. At the same time, write-caching and storing steps can be accelerated.Type: ApplicationFiled: October 13, 2003Publication date: February 23, 2006Inventors: Robert Jochemsen, Maarten Bodlaender, Wilhelmus Franciscus Fontijn, Adrianus Denissen, Nicolass Lambert

Publication number: 20050132251Abstract: In a file system and in particular in a real-time file system it might not be possible to write a data to disc completely. Nevertheless the data that has been written to disc is often still useful, for example in case of an MPEG-stream. Marking parts of the file defective in the file system providing meta-data enables an application to perform application specific error correction or error concealment By using a filter driver, the file system can be extended with this error handling, thus making this functionality available to every application.Type: ApplicationFiled: December 23, 2002Publication date: June 16, 2005Applicant: Koninklijke Philips Electronics N.V.Inventors: Adrianus Denissen, Robert Jochemsen, Nicolaas Lambert, Hong Li, Albert Rijkaert, Rudi Wijnands
