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.

Abstract: An apparatus for synchronizing audio data and visual data and a method therefor are provided. The apparatus includes a splitter, a synchronization unit coupled to the splitter, an audio control unit coupled to the splitter and the synchronization unit, and a visual data processing unit coupled to the splitter and the synchronization unit. The splitter receives an application layer data frame including audio data and visual data and splits the visual data from the audio data. The synchronization unit receives audio timing information of the audio data and acquires synchronization information according to the audio timing information and external timing information. The audio control unit receives and temporarily stores the audio data and outputs the audio data according to the synchronization information. The visual data processing unit analyzes and temporarily stores the visual data and outputs the visual data together with the audio data according to the synchronization information.
