Apparatus and method for recording/reproducing moving picture and recording medium

A method of recording/reproducing data on/from a recording medium, comprising:

• dividing an image into a plurality of basic units and recording the basic units on the recording medium, wherein each basic unit comprises at least video data and audio data, and the audio data comprises at least one type of audio stream;
• and
• recording basic unit information related to a corresponding part of the image in each basic unit on the recording medium,
• wherein:
• the basic unit information includes first state information related to a type of the first audio streams, and the first state information represents a state in which the first audio is original audio, or a state in which the first audio has been modified from the original audio, and
• the basic unit information further comprises second state information related to a second-type of the audio streams, and the second state information represents a state in which the second audio remains as original audio, a state in which the second audio has been modified from the original audio, a dummy state in which the second audio has the same stream as a stream in the original audio of the first audio, and a state in which the second audio has been modified from the dummy state.

A method of playing back a recording medium on having a moving picture, the method comprising:

• reading first state information on first audio and, if second audio exists, second state information on the second audio, before reproducing the moving image, the moving image being divided into a plurality of basic units, and basic unit information being related to the moving image recorded in each basic unit, each basic unit comprising at least video data and audio data, and the audio data comprising the first audio, or the first audio and the second audio, and the basic unit information including first state information on the first audio and, if the second audio exists, the second state information on the second audio;
• and
• reporting the read state information to a user before reproducing the moving image,
• wherein the second state information represents a state in which the second audio remains as original audio, a state in which the second audio has been modified from the original audio, a dummy state in which the second audio has a same stream as a stream in the original audio of the first audio, and a state in which the second audio has been modified from the dummy state.
