Patent ID: 8620140

Claim:
A reproducing apparatus for reproducing contents data recorded on a recording medium, the apparatus comprising: a processor to execute code and process data; an input unit configured to input a non-real time data and a real time data reproduced from the recording medium, the non-real time data containing a file storing as a set of at least an executable program code to perform a controlling operation of data reproduced from the recording medium when executed by the processor, image data composing an operation screen prompting a user to perform an operation, and a plurality of pieces of sound data with which sound effects are reproduced, and the real time data containing at least moving picture data and subtitle data; a storage unit configured to store the program code that has been input by the input unit; an image data storing unit configured to store the image data that has been input by the input unit; a first combining unit configured to combine decoded moving picture data of which the moving picture data that had been input by the input unit has been decoded and decoded subtitle data of which the subtitle data that had been input by the input unit has been decoded; and a second combining unit configured to combine the decoded image data that has been stored in the image data storing unit and the combined data of the decoded moving picture and the decoded subtitle data combined by the first combining unit, in accordance with the program code stored in the storage unit by reproducing the decoded image data, the decoded moving picture data, and the decoded subtitle data as independent display planes which are combined for display, wherein a sound effect is reproduced, based on the controlling operation, in synchronization with a displayed graphics object of the decoded image data display plane, while reproducing the combined independent display planes, by assigning an effect sound to image data for the displayed graphics object through an assignment command, which identifies the image data by an image id, and which identifies the effect sound by a sound id, and by executing, after the assigning, a play command to reproduce the effect sound, by referencing the sound id, when the image data corresponding to the image id is displayed.
