Patent ID: 8213775

Claim:
An information processing apparatus for reproducing sound data and image data, comprising: a play interval specification section for specifying a play interval within which sound of the sound data to be reproduced as background music exists; and a reproduction control information production section for allocating the image data to the play interval specified within a full reproduction interval of the sound data, including a tail fade-out interval at the tail of the play interval and excluding a head no-sound interval and a tail no-sound interval, and producing reproduction control information for controlling reproduction of the sound data and the image data so that the image data are reproduced only while the reproduction data within the play interval are reproduced, wherein the head no-sound interval and the tail no-sound interval are intervals within which sound output level is zero, and wherein the tail fade-out interval is an interval within which the sound output level decreases from a nonzero value to zero.
