Description




BRIEF DESCRIPTION OF THE INVENTION




The present invention relates generally to monitors. More particularly, the present invention relates to a connector to couple a monitor to a computer.




BACKGROUND OF THE INVENTION




A monitor is typically configured to display images for a user. For certain applications, the monitor can produce images in accordance with video data received from a computer that is coupled to the monitor. To enhance its functionality, the monitor can be provided with an Universal Serial Bus (USB) port to which a keyboard or a mouse can be coupled.




Coupling of a monitor to a computer sometimes can require a number of separate cables that transmit different types of data between the monitor and the computer. For instance, coupling of the monitor to the computer can require one cable to transmit video data associated with operation of the monitor and another separate cable to transmit USB data associated with operation of a keyboard or a mouse that is coupled to the monitor. Operation of the monitor also can require a cable that couples the monitor to a power supply, such as, for example, an external power supply. Use of separate cables can complicate installation of a computer system and can reduce the workspace available to a user.




Attempts have been made to reduce the number of separate cables needed to couple a monitor to a computer. While providing some benefits, such previous attempts typically suffered from one or more shortcomings. In particular, such previous attempts often provided limited flexibility in the types of monitors and computers that can be coupled with a reduced number of separate cables. Also, for some previous attempts, video data is transmitted between a monitor and a computer via one or more intermediate connections, which can introduce distortions to the transmitted video data and impair the quality of the resulting image. And, some previous attempts do not provide transmission of audio data to a monitor for operation of, for example, a microphone or a speaker that is coupled to the monitor.




It is against this background that a need arose to develop the apparatus described herein.

150


.




The foregoing discussion provides a general overview of the components and operation of one embodiment of the invention. Attention now turns to

FIG. 2

, which illustrates a connector


200


to couple a monitor (e.g., the monitor


102


) to a computer (e.g., the computer


104


) in accordance with another embodiment of the invention.




As shown in

FIG. 2

202


via the openings


208


and


210


. As shown in

FIG. 2

, the adaptor


202


also includes ports


216


and


218


, which are operably disposed in the openings


212


and


214


, respectively. In the present embodiment of the invention, the port


216


is configured to couple the adaptor


202


to an external power supply via a conventional cable, while the port


218


is configured to couple the adaptor


202


to an USB port of the computer via a conventional cable.




The cable


204


includes a first end


220


and a second end


222


. The first end


220

226


and


228


that allow the DVI coupler


224


to be secured to the DVI port of the video card. Alternatively, or in conjunction, the second end


222


can be configured to couple the cable


204


to an ADC port or a Video Graphics Array (VGA) port associated with the video card. Thus, by appropriately configuring the second end


222


, the connector


200


allows the monitor to be coupled to a variety of ports that can be associated with the video card.




As shown in

FIG. 2

, the cable


204

FIG. 2

, outer sheaths


234


and


236


are shown for two different sections of the intermediate portion


232


.




In the present embodiment of the invention, the intermediate portion


232


includes various transmission channels (not shown in

FIG. 2

) that are coupled to the first end


220


of the cable


204


. In particular, a first transmission channel can include a set of conventional cables that couples the first end


220


of the cable


204


to the port


216


of the adaptor


202


to transmit power from the external power supply to the monitor. In the present embodiment of the invention, the first transmission channel can include a pair of cables, one of which supplies a ground voltage, and the other supplies a voltage between approximately +12V and +18V. A second transmission channel can include a set of conventional cables that couples the first end


220


of the cable


204


to the port


218


of the adaptor


202


to transmit USB data between the monitor and the computer. In the present embodiment of the invention, the second transmission channel can include a pair of USB cables connecting the first end


220


of the cable


204


to the port


218


of the adaptor


202


. A third transmission channel can include a set of conventional cables that extends through the openings


208


and


210


of the adaptor


202


and couples the first end


220


to the second end


222


of the cable


204


to transmit video data between the monitor and the computer. Depending on the particular video card and the particular monitor used, video data that is transmitted between the monitor and the computer can be analog video data, digital video data, or a combination thereof. In the present embodiment of the invention, digital video data is transmitted in accordance with Transition Minimized Differential Signaling (TMDS) using three pairs of cables. Depending on the specific application, the third transmission channel also can include cables that transmit clock signals as well as configuration data associated with operation of the monitor.
