Publication number: 20150006758Abstract: The present invention relates to several techniques for managing the contents of proxy tables in ways that optimize performance, latency, and reliability for communication networks, while ensuring a certain number of early-acting proxies per restricted device. An entity is allowed to keep a required number of proxies per resource-restricted device by removing or adding proxy table entries. Furthermore, the entity is allowed to keep track of early-acting proxies based on forwarding strategies, reporting strategies and/or polling strategies. Thereby, proxy table entries can be controlled to optimise overall system performance and reliability characteristics.Type: ApplicationFiled: February 11, 2013Publication date: January 1, 2015Inventors: Koen Johanna Guillaume Holtman, Bozena Erdmann

Publication number: 20140330998Abstract: Configurability and controllability over the initiation of automatic docking for a portable device seeking to dock wirelessly with a docking station in a wireless docking system environment are achieved by the method and system disclosed herein. The portable device detects the docking station in the wireless docking environment. When the docking station is detected, a communication path is established between the portable device and the docking station. A received signal characteristic level is measured for a received signal. The received signal characteristic level is compared to a determined threshold so that, at least when the received signal level exceeds the determined threshold, docking the portable device to the docking station is able to be completed.Type: ApplicationFiled: November 14, 2012Publication date: November 6, 2014Inventors: Walter Dees, Koen Johanna Guillaume Holtman

Publication number: 20140301575Abstract: Efficiency for mixing audio signals from one or more portable user devices in an audio system employing a number of docking station is achieved by a docking station that includes a controller for detecting the presence of an activated mixer associated with another docking station in the system. The controller activates its associated mixer when no activated mixer associated with another docking host in the system is detected. When its associated mixer is activated, the controller in the one docking station causes its associated mixer to be connected both to the audio sound system for supplying an input signal thereto and indirectly to the output(s) of the one or more portable devices. Transfer of mixing from one docking station to another in the same system upon the occurrence of a particularly defined event is also described.Type: ApplicationFiled: November 9, 2012Publication date: October 9, 2014Applicant: Koninklijke Philips N.V.Inventors: Koen Johanna Guillaume Holtman, Walter Dees

Patent number: 7865059Abstract: A device for recording information records a real-time data stream (51) in blocks having contiguous logical addresses (LA0-LA5) on a record carrier at corresponding physical addresses (PA0-PA8). The device has allocation means for allocating physical addresses to logical addresses, the allocation including at least one logically contiguous range of blocks allocated to at least a part of the real-time data stream. During recording, auxiliary data means (34,33) process auxiliary data related to the real-time data and record the auxiliary data as auxiliary blocks on the record carrier. The auxiliary data means assign physical addresses to the auxiliary blocks (61), which physical addresses are excluded from allocation to logical addresses and are within or near a physical address range (PA0-PA8) corresponding to the at least one logically contiguous range of blocks (LA0-LA5) allocated to the said part of the real-time data stream.Type: GrantFiled: October 1, 2004Date of Patent: January 4, 2011Assignee: Koninklijke Philips Electronics N.V.Inventor: Koen Johanna Guillaume Holtman

Publication number: 20090189912Abstract: Conventional concepts of signal processing have no specifically adapted judder compensation for combined streams of fields from graphics and further image signals and therefore show animation judder artifacts. Presently judder compensation is adapted for further image signals like a video only, and motion blur in a video image signal often hides judder artifacts. However, this is not the case for graphics objects like bitmaps. At an increased reference refresh rate (60 fps) the inventive concept provides a combined stream (11) of fields of the further (3) and the graphics (7A, 7B) image signals, in particular comprising animations (35). By interpolating (18A, 18B) between the image fields of the graphics image signal (7A, 7B) already upon creating the graphics image signal (7A, 7B), the input refresh rate (24 fps) of a graphics image signal (7A, 7B) is raised to the reference refresh rate (60 fps) before the combining step (23).Type: ApplicationFiled: October 11, 2005Publication date: July 30, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventor: Koen Johanna Guillaume Holtman

Publication number: 20080282319Abstract: A content distribution system (300) has access control according to a predefined data access format. The system has organizations (32) for providing content data and related meta data on record carriers (34), and a rendering device (39), and applications for manipulating the content data and related meta data. An access policy for the organization is set according to the predefined data access format, and has access parameters for controlling access to resources of the rendering device and to said content data and related meta data. An organization application (35) complying with the access policy of the organization for accessing said data is executed while accessing the resources of the rendering device according to the access policy of the organization. According to the invention a user access policy is maintained that restricts, for the organization application, access to the resources of the rendering device relative to the access policy of the organization.Type: ApplicationFiled: November 6, 2006Publication date: November 13, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Wilhelmus Franciscus Johannes Fontijn, Johan Cornelis Talstra, Philip Steven Newton, Koen Johanna Guillaume Holtman
