Apparatus for audio data processing and method therefor

Abstract

An apparatus for audio data processing and a method therefor are provided. The apparatus includes a processing unit and an audio decoder. The processing unit receives an audio data stream, and the audio data stream includes a first frame header that complies with a communication protocol and an audio data encoded in an audio compression format. The processing unit parses the audio data stream to split the first frame header and the audio data, generates at least one frame information according to the first frame header, and acquires a second frame header according to the frame information. Here, the second frame header complies with an international audio and video coding standard. The audio decoder is coupled to the processing unit, receives the second frame header and the audio data from the processing unit, and decompresses the audio data according to the second frame header.

What is claimed is: 
     
         1 . An apparatus for audio data processing, the apparatus comprising:
 a processing unit receiving an audio data stream, the audio data stream comprising a first frame header and an audio data, the first frame header complying with a communication protocol, the audio data being encoded in an audio compression format, the processing unit parsing the audio data stream to split the first frame header and the audio data, generating at least one frame information according to the first header, and acquiring a second frame header according to the at least one frame information, wherein the second frame header complies with an international audio and video coding standard; and   an audio decoder coupled to the processing unit, the audio decoder receiving the second frame header and the audio data and decompressing the audio data according to the second frame header.   
     
     
         2 . The apparatus as recited in  claim 1 , wherein the communication protocol is digital audio broadcasting or digital audio broadcasting plus. 
     
     
         3 . The apparatus as recited in  claim 1 , wherein the communication protocol is digital audio broadcasting, and the audio compression format is high efficiency advanced audio coding. 
     
     
         4 . The apparatus as recited in  claim 2 , wherein the first frame header is in an audio super frame format complying with digital audio broadcasting or digital audio broadcasting plus. 
     
     
         5 . The apparatus as recited in  claim 2 , wherein
