Abstract

Disclosed is a method for processing multimedia data at a mobile communication terminal having at least one sub processor besides a main processor, including the steps of analyzing information of multimedia data to be processed at the main processor, selecting a processor at the main processor for processing the multimedia data according to analyzed result of the information, calling codec needed for the data processing at the selected processor, and processing the multimedia data at the selected processor by using the called codec.

Claims

1. A method for processing multimedia data in a mobile communication terminal having at least one sub processor besides a main processor, comprising the steps of:

analyzing information of multimedia data to be processed at the main processor;

selecting a processor at the main processor for processing the multimedia data according to analyzed result of the information;

calling codec needed for the data processing at the selected processor; and

processing the multimedia data at the selected processor by using the called codec.

2. The method of claim 1, wherein the sub processor is a digital signal processor.

3. The method of claim 1, wherein the codec is stored at different addresses in one memory.

4. The method of claim 1, wherein selecting the processor is determined according to the file type of the multimedia data to be processed.

5. The method of claim 4, wherein the step of selecting the processor further comprises a step of determining the processor according to the file size of the multimedia data to be processed.

6. The method of claim 4, wherein the step of selecting the processor further comprises a step of determining the processor according to the resolution of the file when the multimedia data to be processed is image data or video data.

7. The method of claim 4, wherein the step of selecting the processor further comprises a step of determining the processor according to sampling frequency and a frame rate when the multimedia data to be processed is video data.

8. The method of claim 4, wherein the step of selecting the processor further comprises a step of determining the processor according to sampling frequency when the multimedia data to be processed is audio data.

9. A mobile communication terminal, comprising:

a main processor performing general control of the mobile communication terminal, and selectively processing according to the characteristic of the multimedia data to be processed;

at least one sub processor for multimedia data processing; and

a memory storing different codecs at different locations accessible from the main processor and the sub processor, respectively.

10. The mobile communication terminal of claim 9, wherein the sub processor is a digital signal processor.

11. The mobile communication terminal of claim 9, wherein the codec is stored at different addresses in one memory.

12. The mobile communication terminal of claim 9, wherein the main processor determines a processor for processing the multimedia data according to the file type of the multimedia data to be processed.

13. The mobile communication terminal of claim 9, wherein the main processor determines a processor for processing the multimedia data according to the file size of the multimedia data to be processed.

14. The mobile communication terminal of claim 12, wherein the main processor determines a processor for processing the multimedia data according to the file resolution when the type of the multimedia data to be processed is image data or video data.

15. The mobile communication terminal of claim 12, wherein the step of selecting the processor further comprises a step of determining the processor according to sampling frequency and a frame rate when the multimedia data to be processed is video data.

16. The mobile communication terminal of claim 12, wherein the main processor determines the processor for processing the multimedia data according to sampling frequency when the multimedia data to be processed is audio data
