摘要:
A digital communication system for transmitting and receiving video data signals and control data signals over a transmission line comprises an open-loop equalizer circuit and a control data extension circuit. The open-loop equalizer circuit is operable to receive video signals transmitted over the transmission line and output equalized video data signals. The control data extension circuit is operable to inject a boost current at the receive end of the transmission line during a positive transition in the control data signal, and clamp the receive end of the transmission line during a negative transition of the control data signal.

A digital communication system for transmitting and receiving Digital Visual Interface (DVI) communication data signals and Display Data Channel (DDC) communication signals over a transmission line comprises an open-loop equalizer circuit and a DDC extension circuit. The open-loop equalizer circuit is operable to receive DVI communication signals transmitted over the transmission line and output equalized DVI communication data signals. The DDC extension circuit is operable to inject a boost current at the receive end of the transmission line during a positive transition in the DDC communication signal, and clamp the receive end of the transmission line during a negative transition of the DDC communication signal.

摘要:
The present invention provides a security control system, comprising a system controller (2) arranged to receive video signals from a plurality of video sources, and to selectively output a subset of the received video signals for display on a display means, and a display controller (10, 12) arranged to receive the subset of video signals output by the system controller, and to process those signals to generate images for display on the display means. In accordance with the present invention, the system controller (2) is further arranged to receive alarm signals, each alarm signal being associated with a video source, the system controller (2) being responsive to receipt of an alarm signal to output the video signal of the associated video source to the display controller. The display controller (10, 12) is then arranged to cause any images generated from video signals associated with alarm signals to be displayed in a predetermined area (M11) of the display means.By ensuring that all of the video information associated with alarms is displayed in a predefined area, it is easier for the operator to review that video information in order to ensure that effective action is taken in response to the alarm condition(s).
