RECORDING MEDIUM, REPRODUCTION DEVICE, PROGRAM, REPRODUCTION METHOD, AND INTEGRATED CIRCUIT

摘要

A playback apparatus and method that executes an application while playing back a digital stream. A mixer is configured to, when a flag included in a playlist is set to ON, mix an output of a click sound using sound data with an audio output of the digital stream when a user performs an operation on an application while the application is executed. When the flag is set to OFF, the mixer refrains from mixing the output of the click sound with the audio output.
