The software driver may be configured to work with different display codecs at different periods of time while using a default configuration. Other embodiments are also described. ## Claims ### Claim 1 A non-transitory machine readable storage medium storing machine-readable instructions which when executed by a data processing system cause the system to perform operations comprising: controlling a plurality of codecs including a first codec and a second codec using a software componentin a first configuration, wherein the software component is configured to control the first codec via a first set of commands, and wherein the software component is configured to control the second codec via the first set of commands, wherein the first configuration and the first set of commands are maintained to control the second codec when the first codec is changed to the second codec. ### Claim 2 (depends on 1) The non-transitory machine readable storage medium of claim 1 wherein the software component is configured to recognize each of a plurality of display devices. ### Claim 3 (depends on 2) The non-transitory machine readable storage medium of claim 2 wherein the plurality of display devices comprises at least one of a flat panel, a LCD (liquid crystal display device), an HDTV (high definition television) device, a plasma display device, or a computer monitor device. ### Claim 4 (depends on 1) The non-transitory machine readable storage medium of claim 1 further comprising instructions that cause the data processing system to perform operations comprising receiving digital signals from a cable television outlet. ### Claim 5 (depends on 1) The non-transitory machine readable storage medium of claim 1 further comprising instructions that cause the data processing system to perform operations comprising receiving digital signals from a satellite. ### Claim 6 (depends on 1) The non-transitory machine readable storage medium of claim 1 further comprising instructions that cause the data processing system to perform operations comprising receiving digital signals from a wireless transmission device. ### Claim 7 A method comprising: controlling a plurality of codecs including a first codec and a second codec using a software component in a first configuration, wherein the software component is configured to control the first codec via a first set of commands, and wherein the software component is configured to control the second codec via the first set of commands, wherein the first configuration and the first set of commands are maintained to control the second codec when the first codec is changed to the second codec. ### Claim 8 (depends on 7) The method of claim 7 wherein the software component is part of a graphics controller for communicating with a plurality of codecs. ### Claim 9 (depends on 8) The method of claim 8 wherein each of the codecs comprises a hardware portion that communicates with the software component such that the graphics controller recognizes each of the plurality of codecs at different periods of time. ### Claim 10 (depends on 8) The method of claim 8 where the software component is a part of the graphics controller known as a universal software component. ### Claim 11 A system comprising: a processor; a memory coupled to the processor; a first display device that communicatively couples with the processor through a first codec to display images; and a graphics controller having a software component in a first configuration to control a plurality of codecs, wherein the software component is configured to control the first codec via a first set of commands, and wherein the software component is configured to control the second codec via the first set of commands, wherein the first configuration and the first set of commands are maintained to control the second codec when the first codec is changed to the second codec, the graphics controller being communicatively coupled to the processor. ### Claim 12 (depends on 11) The system of claim 11 wherein the software component comprises a universal software component. ### Claim 13 (depends on 11) The system of claim 11 wherein the first display device is a digital display device. ### Claim 14 (depends on 13) The system of claim 13 wherein the first display device comprises at least one of a flat panel display device, a LCD (liquid crystal display) device, an HDTV (high definition television) device, a plasma display device, or a computer monitor device. ### Claim 15 A graphics controller comprising: a memory, and a software component coupled to the memory, wherein the software component is in a first configuration to control a plurality of codecs including a first codec and a second codec, wherein the software component is configured to control the first codec via a first set of commands, and wherein the software component is configured to control the second codec via the first set of commands, wherein the first configuration and the first set of commands are maintained to control the second codec when the first codec is changed to the second codec. ### Claim 16 (depends on 15) The graphics controller of claim 15 wherein the software component comprises a universal software component. ### Claim 17 (depends on 15) The graphics controller of claim 15 further comprising a storage medium for the software component that communicates with at least the first codec, the software component recognizing each of the plurality of codecs. ### Claim 18 A method comprising: emulating a graphics controller comprising a universal software component to control a plurality of codecs including a first codec and a second codec, wherein the universal software component is in a first configuration to control the plurality of codecs, wherein the universal software component is configured to control the first codec via a first set of commands, and wherein the software component is configured to control the second codec via the first set of commands, wherein the first configuration and the first set of commands are maintained to control the second codec when the first codec is changed to the second codec. ### Claim 19 (depends on 18) The method of claim 18 further comprising emulating replacing the first one of the plurality of codecs with the second one of the plurality of codecs. ### Claim 20 (depends on 19) The method of claim 19 wherein the second one of the plurality of codecs is an SDVO codec.
