摘要：
When sample data is played back, audio guide data G1 and G2 and subsequent frame data are played back based on usage license information L1 contained in the sample data. When high-quality data is generated, the audio guide data G1 and G2 and the usage license information L1 are overwritten based on usage license information L2 contained in additional data. When the high-quality data is played back, audio guide data G1′ and G2′ and subsequent frame data are played back based on usage license information L3. A user is then able to identify the playback status of the sample data or high-quality data by listening to an audio guide.
