INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD
First Claim
1. An information processing apparatus comprising:
- input means for receiving a first operation and a second operation input by a user;
playback means for obtaining predetermined data to play it back based on the operation input by the user from said input means; and
display control means for controlling, in correspondence with a virtual hierarchical structure for classifying the predetermined data, the display of a display screen indicating each hierarchy level, and for controlling the display of a predetermined mark in the display screen, wherein;
said display control means controls the display of the predetermined mark corresponding to the predetermined data which is played back by said playback means in a manner different from other non-selected marks while the predetermined mark is being selected;
when the first operation is input from said input means, said display control means controls the selection of the predetermined mark to be changed, and said playback means plays back the predetermined data corresponding to the newly selected mark; and
when the second operation is input from said input means, said display control means controls the display of the display screen indicating a different hierarchy level based on the hierarchical structure.

Abstract
An information processing apparatus having an input configured to receive a first operation and a second operation input by a user, a playback unit configured to obtain predetermined data and play back the data based on the operation input by the user from the input; and a display control unit configured to control, in correspondence with a virtual hierarchical structure for classifying the predetermined data, a display of a display screen indicating each hierarchy level, and for controlling a display of a predetermined mark in the display screen. The display control unit also controls the display of the predetermined mark corresponding to the predetermined data which is played back by the playback unit in a manner different from other non-selected marks while the predetermined mark is being selected.

9. An information processing method comprising:
-
an input control step of controlling an input of a first operation and a second operation by a user; a playback step of obtaining predetermined data based on the input operation by the user, which is controlled by processing of said input control step; and a display control step of controlling, in correspondence with a virtual hierarchical structure for classifying the predetermined data, the display of a display screen indicating each hierarchy level, and of controlling the display of a predetermined mark in the display screen, wherein; processing of said display control step controls the display of the predetermined mark corresponding to the predetermined data which is played back by processing of said playback step in a manner different from other non-selected marks while the predetermined mark is being selected; when the input of the first operation is controlled by processing of said input control step, processing of said display control step controls the display of the display screen so that the selection of the predetermined mark is changed, and processing of said playback step plays back the predetermined data corresponding to the newly selected mark; and when the input of the second operation is controlled by processing of said input control step, processing of said display control step controls the display of the display screen indicating a different hierarchy level based on the hierarchical structure.

10. A program allowing a computer to execute:
-
an input control step of controlling an input of a first operation and a second operation by a user; a playback step of obtaining predetermined data based on the input operation by the user, which is controlled by processing of said input control step; and a display control step of controlling, in correspondence with a virtual hierarchical structure for classifying the predetermined data, the display of a display screen indicating each hierarchy level, and of controlling the display of a predetermined mark in the display screen, wherein; processing of said display control step controls the display of the predetermined mark corresponding to the predetermined data which is played back by processing of said playback step in a manner different from other non-selected marks while the predetermined mark is being selected; when the input of the first operation is controlled by processing of said input control step, processing of said display control step controls the display of the display screen so that the selection of the predetermined mark is changed, and processing of said playback step plays back the predetermined data corresponding to the newly selected mark; and when the input of the second operation is controlled by processing of said input control step, processing of said display control step controls the display of the display screen indicating a different hierarchy level based on the hierarchical structure.
