Patent number: 7940694Abstract: The principles of the invention allow an intermediate device, such as a router, to intelligently filter redundant data streams provided by one or more hosts. In the event of a network disturbance, the router may stop filtering one of the now needed redundant data streams in a manner that may reduce the consumption of network resources, such as bandwidth, without having to modify end-user applications residing on subscriber devices. Therefore, the router acting in accordance with the principles of the invention may transparently provide data streams to subscriber devices despite the occurrence of a network disturbance that may otherwise prevent the subscriber devices from receiving the data streams.Type: GrantFiled: November 14, 2005Date of Patent: May 10, 2011Assignee: Juniper Networks, Inc.Inventor: Thomas J.

Publication number: 20090241148Abstract: A video transmitter can adaptively alter its transmission rate to plural receivers which receive video via multicast transmission. While the transmitter is initially in the “no tuning state,” the need for a video tune-up state change can be determined by calculating if the current generated A/V retry transmission rate is greater than the video tune-up start threshold and if it was triggered more than the video tune-up interval ago. If so, then the state can be set to “tuning up” and the retransmission rate can be increased by the video tune-up step, as shown in FIG. 7. However, if the state is set to “tuning up” and it is determined that the current generated A/V retry transmission rate is greater than the video tune-up stop threshold, then “tuning-up” is no longer required, and the state is set such that “tuning up” is no longer true such that the state returns to the “no tuning” state.Type: ApplicationFiled: October 20, 2008Publication date: September 24, 2009Inventor: Lawrence Lo

Publication number: 20090064267Abstract: Provided are a method of automatically adjusting content rendering devices according to the genres of content, and a broadcasting system and a receiving system that perform the method. The broadcasting system broadcasts a composite data set that includes content and meta data, the meta data including set values of optimal images and sounds depending on the program genre of the content. The receiving system receives and parses the broadcasted composite data set into the original content and the meta data associated with the original content. The receiving system processes the set values of the optimal images and sounds of the corresponding broadcast genre from the meta data so as to automatically adjust a content rendering device such as a video display system or an audio system. Thus, an optimal visual and audio environment is established.Type: ApplicationFiled: June 12, 2008Publication date: March 5, 2009Applicant: Samsung Electronics Co., Ltd.Inventor: Hwa-kyung Lee

Publication number: 20080313696Abstract: A thermal pad controlled equalizer that adjusts the slope and gain of an amplifier in response to changes in ambient temperature, effectively simulating automatic gain control. The equalizer has a slope pad and a gain pad. The slope pad increases the attenuation of the signal in response to increases in ambient temperature. The gain pad decreases the attenuation when ambient temperature increases. Thus, the slope and gain pads together compensate for temperature effects on the system.Type: ApplicationFiled: June 12, 2007Publication date: December 18, 2008Inventor: Robert M. Blumenkranz

Patent number: 7380264Abstract: A system for unifying heterogeneous multimedia tuners. The system produces a unified channel lineup and coordinates multiple diverse tuners to perform multimedia tasks associated with the unified lineup. In one implementation, tuner allocation policy allows behind-the-scenes tuner assignment and on-the-fly tuner swapping so that the user experience is seamless, access quality is continuously optimized, and tuners with the most bandwidth are kept available.Type: GrantFiled: August 13, 2004Date of Patent: May 27, 2008Assignee: Microsoft CorporationInventor: Peter J. Potrebic

Publication number: 20080049104Abstract: A video acquirement apparatus to acquire a video signal of monitoring area, to convert the acquired video signal into a differential video signal and a network stream, and to transmit the converted signal to a repeater apparatus using a UTP cable. The repeater apparatus supplies power to the video acquirement apparatus using the UTP cable, and receives the differential video signal and the network stream from the video acquirement apparatus. If network condition is unsatisfactory, the repeater apparatus outputs the received differential video signal to a video recording apparatus using one UTP cable. The video recording apparatus converts the output differential video signal using one UTP cable into a general video signal, and variably amplifies and records the converted general video signal.Type: ApplicationFiled: August 20, 2007Publication date: February 28, 2008Applicant: Samsung Electronics Co., Ltd.Inventor: Il-kwon CHANG

Publication number: 20070300284Abstract: A method and apparatus for automatic compensation of insertion loss in video signals transmitted over conductors is presented. The present invention is particularly applicable to the transmission of video over long lengths of CAT-5 or similar twisted-pair cables. A reference signal having a known form and strength (e.g. a pulse signal) is provided to each pair of conductors carrying a component of a video signal from a transmitter to a receiver. The receiver includes adjustable gain amplifiers for each conductor pair over which a component of the video signal is transmitted. The gains of the amplifiers are initially set at an initial level (e.g., their maximum gain) to allow detection of the reference signal. Once the reference signal is detected in a conductor pair, the amplifier gains are adjusted such that the level of the reference signal is restored approximately to its original form and strength.Type: ApplicationFiled: June 23, 2006Publication date: December 27, 2007Applicant: RGB SYSTEMS, INC., (DBA EXTRON ELECTRONICS)Inventors: Raymond William Hall, Donald E.
