Abstract

A method and apparatus for mixing audio streams, and an information storage medium that stores mixing information. The information storage medium includes at least one audio stream that contains a multiplicity of audio data obtained from respective multiple channels, and mixing information used to mix at least parts of the multiplicity of audio data. Accordingly, it is possible to mix and reproduce different types of channel components without changing the channel formats of different audio streams. Furthermore, it is also possible to perform dynamic mixing on multiple channel components, thus enabling adaptation to a change in audio content and characteristics thereof and thereby reproducing audio data more appropriately. In particular, since mixing information is described in interactive data allowing an interaction with a user, it is possible to provide the user with more applications.

Claims

1. A method of reproducing an audio stream, comprising;

decoding at least one audio stream containing a multiplicity of audio data obtained from respective multiple channels; and

mixing audio data from at least two channels of the multiple channels, based on mixing information recorded in interactive data.

2. The method of claim 1, wherein the mixing of the audio data comprises mixing the audio data obtained from at least two channels of the multiple channels, based on mixing information recorded in a markup document in a markup language that enables an interaction with a user or is recorded in program data which is recorded in a different file from the markup document and provides the user with a predetermined application.

3. The method of claim 1, wherein the mixing of the audio data comprises adjusting output levels of the audio data and mixing the adjusted output levels, based on the mixing information including stream channel type information and attributes of the stream channel type information, the stream channel type information that specifies the multiplicity of audio data and obtained from the respective multiple channels using predetermined integers, and the attributes that represent mixing coefficient information specifying the output levels of the multiplicity of audio data and output from the channels.

4. A method of reproducing an audio stream, comprising;

decoding at least one audio stream containing a multiplicity of audio data obtained from multiple channels; and

mixing and reproducing audio data from at least two channels of the multiple channels, based on mixing information recorded in interactive data, without changing channel formats of different audio streams.

5. An audio mixing method, comprising:

mixing and reproducing different types of channel components without changing channel formats of audio streams, constituting different types of audio content.

6. A method of reproducing an audio stream, comprising:

detecting a multiplicity of audio data, which is to be combined, based on mixing-relation information and channel information contained in the multiplicity of audio data;

adjusting output levels of the detected multiplicity of audio data based on mixing coefficient information; and

mixing the adjusted multiplicity of audio data.
