A method of switching output interfaces for a computer system includes recording a plurality of system operation statuses of a multimedia signal corresponding to the computer system to switch from a first output interface to a second output interface and generating at least a switching condition; and switching the multimedia signal of the computer system from the first output interface to the second output interface when an operating status of the computer system matches the at least a switching condition.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method of switching output interfaces for a computer system comprising: recording a plurality of system operation statuses of a multimedia signal corresponding to the computer system to switch from a first output interface to a second output interface and generating at least a switching condition; and switching the multimedia signal of the computer system from the first output interface to the second output interface when an operating status of the computer system matches the at least a switching condition. 2. The method of claim 1, wherein the plurality of system operation statuses of the multimedia signal corresponding to the computer system to switch from the first output interface to the second output interface is performed in a predetermined time period. 3. The method of claim 1, wherein the at least a switching condition is generated by a weighting design or a mathematical model. 4. The method of claim 3, wherein the mathematical model is a Markov Chain model. 5. The method of claim 1, wherein the system operation statuses include at least one of an operating status of the computer system, executing or shutting down at least a program, system volume adjustment, status of internet connection, location information or calendar information. 6. A computer system, comprising: a plurality of output interfaces; a processor; and a storage device, for storing program code, wherein the program code instructs the processor to execute the following steps: recording a plurality of system operation statuses of a multimedia signal corresponding to the computer system to switch from a first output interface to a second output interface and generating at least a switching condition; and switching the multimedia signal of the computer system from the first output interface to the second output interface when an operating status of the computer system matches the at least a switching condition. 7. The computer system of claim 6, wherein the plurality of system operation statuses of the multimedia signal corresponding to the computer system to switch from the first output interface to the second output interface is performed in a predetermined time period. 8. The computer system of claim 6, wherein the at least a switching condition is generated by a weighting design or a mathematical model. 9. The computer system of claim 8, wherein the mathematical model is a Markov Chain model. 10. The computer system of claim 6, wherein the system operation statuses include at least one of an operating status of the computer system, executing or shutting down at least a program, system volume adjustment, status of internet connection, location information or calendar information.
