摘要 |
When sample data is played back, audio guide data G 1 and G 2 and subsequent frame data are played back based on usage license information L 1 contained in the sample data. When high-quality data is generated, the audio guide data G 1 and G 2 and the usage license information L 1 are overwritten based on usage license information L 2 contained in additional data. When the high-quality data is played back, audio guide data G 1 ' and G 2 ' and subsequent frame data are played back based on usage license information L 3 . A user is then able to identify the playback status of the sample data or high-quality data by listening to an audio guide.
