Information processing apparatus and information processing method

An information processing method of an information processing apparatus comprising:

• controlling an input of a first operation by a user;
• obtaining predetermined data to play back based on the operation by the user, the input of which is controlled by processing of the controlling the input step;
• and
• controlling, by the information processing apparatus and in correspondence with a virtual hierarchical structure in which data is registered based on a predetermined condition for classifying the predetermined data, the display of a first display screen indicating each hierarchy and of a predetermined mark in the first display screen,
• wherein, in processing of the controlling the display step, the display of the predetermined mark corresponding to the predetermined data which is played back by processing of the obtaining step is controlled so that the predetermined mark is displayed as a selected state,
• wherein, when the input of the first operation is controlled by processing of the controlling the input step, the display is controlled in processing of the controlling the display step so that selection of the predetermined mark will be changed, and a plurality of data registered in the virtual hierarchical structure corresponding to the newly selected predetermined mark are sequentially played back in processing of the obtaining step, and
• wherein, when a second operation different from the first operation is input by processing of the controlling the input step,
• the predetermined data to be played back is not changed in processing of the obtaining step;
• and
• in processing of the controlling the display step, the display of a second display screen indicating a different hierarchy is controlled based on the virtual hierarchical structure, the second display screen indicating a new mark that corresponds to the unchanged data being played back by processing of the obtaining step and is displayed as a result of the input of the second operation from the input unit.

A non-transitory computer-readable storage medium storing a program, which when executed by a computer, causes the computer to perform a method comprising:

• controlling an input of a first operation by a user;
• obtaining predetermined data to play back based on the operation by the user, the input of which is controlled by processing of the controlling the input step;
• and
• controlling, in correspondence with a virtual hierarchical structure in which data is registered based on a predetermined condition for classifying the predetermined data, the display of a first display screen indicating each hierarchy and of a predetermined mark in the first display screen,
• wherein, in processing of the controlling the display step, the display of the predetermined mark corresponding to the predetermined data which is played back by processing of the obtaining step is controlled so that the predetermined mark is displayed as a selected state,
• wherein, when the input of the first operation is controlled by processing of the controlling the input step, the display is controlled in processing of the controlling the display step so that selection of the predetermined mark will be changed, and a plurality of data registered in the virtual hierarchical structure corresponding to the newly selected predetermined mark are sequentially played back in processing of the obtaining step, and
• wherein, when a second operation different from the first operation is input by processing of the controlling the input step,
• the predetermined data to be played back is not changed in processing of the obtaining step;
• and
• in processing of the controlling the display step, the display of a second display screen indicating a different hierarchy is controlled based on the virtual hierarchical structure, the second display screen indicating a new mark that corresponds to the unchanged data being played back by processing of the obtaining step and is displayed as a result of the input of the second operation form the input unit.
