Patent number: 7120152Abstract: A method of routing a packet in a routing device having a main processor that includes a main cache table and an instant cache table is disclosed. The instant cache stores a recent address and a recent interface associated with the most recent packet transmission process made by the routing device. The method includes the steps of receiving a packet that includes its destination address, checking whether the destination address belongs to the routing device, checking whether the destination address is identical to the recent address if the destination address does not belong to the routing device, and transmitting the packet to the recent interface if the destination address is identical to the recent address. As a result, the core information related to the routing path determination is stored not only in the routing table of the protocol layer but also in the main and instant cache tables included in the main processor.Type: GrantFiled: December 27, 2001Date of Patent: October 10, 2006Assignee: LG Electronics Inc.Inventor: Sung Uk Park

Patent number: 6870576Abstract: An automatic beam limiter circuit (ABL circuit) calculating an average of a video signal at least a portion of the video signal is provided. After a converter circuit converts an analog signal, which is generated from the video signal, to a digital signal, a horizontal and a vertical average circuits calculate a horizontal and vertical averages of the digital signal at least a portion of the digital signal. The portion of the digital signal is a scanned line of the digital signal on a CRT. A comparison circuit compares a first calculation value calculated between a reference value and the vertical average with a second calculation value calculated between the reference value and the horizontal average, and outputs a first comparison signal and a second comparison signal based on the comparison results. A gain control circuit produces a gain control signal for adjusting the brightness/contrast in response to the first comparison and second comparison signals.Type: GrantFiled: November 28, 2001Date of Patent: March 22, 2005Assignee: Samsung Electronics Co., Ltd.Inventor: Sung-Uk Park

Patent number: 5825321Abstract: An apparatus for detecting when an output load of a digital-to-analog converter is changed to another value, automatically sensing the converted output load, and supplying a stable current to the output terminal of the digital-to-analog converter. Normally a digital-to-analog converter operated for processing a digital video signal, has two kinds of output loads, 75.OMEGA. and 37.5.OMEGA.. The apparatus detects whether the output load of the digital analog converter is 75.OMEGA. or 37.5.OMEGA., varies output current according to the detected output load, and therefore actively adjusts the video output voltage to be constantly in the range of 1V.sub.P--P.Type: GrantFiled: August 22, 1996Date of Patent: October 20, 1998Assignee: Samsung Electronics Co., Ltd.Inventor: Sung-Uk Park
