Abstract

This invention relates to a multimedia control center for controlling peripheral devices of a personal computer. The personal computer system comprises a processor for performing multi-tasking applications, an application program executed in the processor, an input device for receiving user inputs for the application program, a peripheral device for performing a peripheral function, a device driver installed in the processor for controlling the peripheral device according to peripheral control signals, and a multimedia control program for receiving the peripheral control signals generated by a multimedia control center according to user inputs and passing the signals to the device driver to control the peripheral device. Such design allows a user to control the peripheral device by using the multimedia control center without suspending or terminating his current application program executed in the processor.

Claims

1. A data processing system comprising:

(1) a processor for performing multi-tasking applications;

(2) a display connected to the processor;

(3) an application program executed in the processor which displays video outputs on the display;

(4) input device means connected to the processor for receiving user inputs for the application program;

(5) peripheral device means connected to the processor for performing a peripheral function;

(6) device driver means installed in the processor for controlling the peripheral device means according to peripheral control signals;

(7) multimedia control means for receiving the peripheral control signals generated by a user and passing the signals to the device driver means to control the peripheral device means without using the display of the processor;

(8) a multimedia interface circuit connected to the processor with a multimedia control panel having a plurality of keys for generating the peripheral control signals according to user inputs; and

(9) an interface driver means installed in the processor for controlling the multimedia interface circuit and transmitting the peripheral control signals to the multimedia control means;

wherein the peripheral device means is controlled by the device driver means according to the peripheral control signals transmitted from the multimedia control means without suspending or terminating the application program executed in the processor; and

wherein the multimedia control means further transmits message signals generated by the device driver means to the interface driver means and the multimedia interface circuit further comprises a display means for displaying the message signals wherein the interface driver means displays the message signals received from the multimedia control means over the display means of the multimedia interface circuit.

2. The data processing system of claim 1 wherein the display means is an LCD (liquid crystal display) panel for displaying the message signals from the device driver means.

3. The data processing system of claim 1 wherein the multimedia interface circuit is built in the input device and wherein the interface driver means controls both the input device and the multimedia interface circuit.

4. The data processing system of claim 3 wherein the input device is a keyboard having a plurality of keys for receiving user inputs for the application program with the multimedia interface circuit built next to the keys for receiving the peripheral control signals.

5. The data processing system of claim 1 wherein the multimedia interface circuit comprises a modem electrically linked to a telephone network for receiving the peripheral control signals.

6. The data processing system of claim 1 wherein the multimedia interface circuit comprises a network interface card electrically linked to a computer network for receiving the peripheral control signals.

7. The data processing system of claim 1 wherein the peripheral device means comprises an optic disk drive and the device driver means comprises an optic disk controller for controlling the optic disk drive and an optic disk driver for controlling the optic disk controller.
