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 and a main processor, the method comprising:

reading an information value of the multimedia data at the main processor, wherein the information value of the multimedia data is associated with at least one of a file type and a file size;

selecting either the main processor or the at least one sub processor at the main processor to process the multimedia data according to the information value of the multimedia data;

calling a codec configured for the multimedia data processing at the selected main processor or at least one sub processor; and

processing the multimedia data at the selected main processor or at least one sub processor by using the called codec,

wherein the information value of the multimedia data is further associated with the resolution of the file when the multimedia data is image data or video data,

wherein the information value of the multimedia data is further associated with a sampling frequency and a frame rate when the multimedia data is video data,

wherein the information value of the multimedia data is further associated with the sampling frequency when the multimedia data is audio data.

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

3. The method of claim 1, further comprising the step of storing the codec to be called at different addresses in one memory.

4. A mobile communication terminal for processing multimedia data, the mobile communication terminal comprising:

a main processor for performing general control of the mobile communication terminal, for reading an information value of the multimedia data which is associated with at least one of a file type and a file size, and for processing the multimedia data;

at least one sub processor for processing the multimedia data; and

a memory for storing different codecs at different locations accessible from the main processor and the at least one sub processor,

wherein the main processor selects either the main processor or the at least one sub processor to process the multimedia data according to the information value of the multimedia data,

wherein the information value of the multimedia data is further associated with the resolution of the file when the multimedia data is image data or video data,

wherein the information value of the multimedia data is further associated with a sampling frequency and a frame rate when the multimedia data is video data,

wherein the information value of the multimedia data is further associated with the sampling frequency when the multimedia data is audio data.

5. The mobile communication terminal of claim 4, wherein the at least one sub processor is a digital signal processor.

6. The mobile communication terminal of claim 4, wherein the different codecs are stored at different addresses in the memory.
