Abstract: A system for compensating for skew in a color video signal transmitted by a cable having multiple conductors is described. A test pulse signal (e.g. a 2 MHz signal) is inserted into the color components (e.g. RGB) of the video signal during time periods in each frame when the RGB video signals are inactive, such as within 300 ?s after the V sync signal. After transmission over the cable, the RGB components with the inserted test signal are delayed relative to each other using a delay line in cooperation with a control circuit. The delay line generates detect signals by detecting relative delays of the test signal pulses inserted in the RGB components. The control circuit controls the amount of delay in the delay line based on the detect signals, so that the RGB components in the video signal outputted by the delay line are synchronized.

Abstract: Disclosed is a KVM management system and method of providing synchronization signal adaptable depending one user's demand. The KVM management system includes a first module and a second module. The first module converts a first type of synchronization signal selected from a first group of synchronization signal combinations into a transitional signal. The second module converts the transitional signal into a second type of synchronization signal selected from a second group of synchronization signal combinations for the display. The transitional signal may be a composite synchronization signal combines one of red, green, blue video signals from the computer and carried on at least one pair of wire in an Ethernet network cable. The type of transitional signal can be predetermined by adjusting a first register stored in the first module. The second type of synchronization signal can be predetermined by adjusting a second register stored in the second module.

Abstract: A UART/USB converting apparatus includes a UART connector, a UART/USB converting chip and a USB connector. The UART connector is for transceiving a UART signal ranging from 0 to 3.3 volts. The UART/USB converting chip electrically connected to the UART connector is for converting between the UART signal and a USB signal. The USB connector electrically connected to the UART/USB converting chip is for transmitting the USB signal.
