The operator having an operation area including one end portion provided along with one end portion of a display area of the elapsed time on the display device and the other end portion provided along with the other portion of the display area of the elapsed time on the display device.

Information reproducing apparatus

The present invention provides an information reproducing apparatus which can directly and intuitively designate a reproduction point, as desired by a user, on the basis of a change in level of a visually-provided information amount. An optical disk reproducing apparatusreads content data from an optical diskloaded and has a reproduction-time specification operating unitwhich is formed by a movable operator MF. The reproduction-time specification operating unitdisplays a change in amount of information on a beat according to elapsed time in the entire content data and includes a movable operator MF which is used to specify reproduction time of the optical diskwhile being movable in an operation area OF corresponding to a display area AThe reproduction-time specification operating unitmoves the movable operator MF such that the center of the movable operator MF corresponds to the reproduction time of the contents data in the beat density data displayed on a display unit

The present invention provides an information processing unit with improved operability. A reading section () reads information recorded in an optical disk, and outputs a read signal. A DSP () detects the read signal and processes to a reproducible form. A quick return button selects at least one of the processing details for starting or stopping the information processing and for changing a reproducing position of the information. When a reproducing state changing section () recognizes a change instruction for changing a processing state for the information, a reproduction control section () changes the processing state by the DSPbased on the processing details selected with the quick return button. Since the processing details for starting or stopping the information processing and for changing a reproducing position are previously stored in the reproducing state changing section () as commonly available change instructions, operating components can be simplified with the operability of the information reproducing unit () substantially improved.

Information processing unit, information processing method, program for the same, recording medium for recording the program therein, and reproducing unit

An information playback apparatus is provided to obtain editing effects using an optical disc in the same sense as an analog record disc is manipulated. An audio editing apparatus for playing back an optical disc such as a CD is provided with a rotatable jog dial, detecting device for detecting the amount of rotation of the jog dial, and sensing device for sensing the presence or absence of a pressing force on the jog dial. When the jog dial is rotated while being depressed with a predetermined pressing force, processing for providing sound effects is performed on the playback data to be played back from the optical disc in response to the amount of rotation detected by the detecting device. It is thereby possible to provide the same feeling of operation as provided by rotating an analog record disc through hand operations to produce playback sounds.

Information playback apparatus

A beat density detecting apparatus and an information playback apparatus are provided to detect distinctive characteristics that music or the like has and to provide the same as a novel information volume. Playback data read out from an information recording medium, such as an optical disc, and sub-code data containing the information of an elapsed track time indicating a recording position of the playback data are provided to a beat detecting unit and a beat position detecting unit, respectively. The beat detecting unit detects the number of occurrences of a change in amplitude at each predetermined frequency of the playback data, and the beat position detecting unit detects an elapsed track time from the sub-code data. Further, a beat density computing unit finds the number of occurrences with respect to the elapsed track time as the characteristics information of a beat density. By displaying the characteristics information of the beat density on a display unit in a way that the user or the like can visually recognize, it is possible to provide the distinctive characteristics that music or the like has not as instantaneous characteristics, but as the characteristics of a relatively long period, or the whole of the characteristics of a signal subject to audio playback.

Beat density detecting apparatus and information playback apparatus

An information playback apparatus is provided, which displays the status of playback in a way more suitable to the human sense as well as detects and then displays as new information the feature characteristic of audio information such as a music selection. The frequency of occurrence of variations in amplitude of audio information to be played back is measured at each predetermined frequency. The measured frequency of occurrence is displayed in a predetermined area of a display unit as the feature information of beat densities with respect to the playback elapsed time of the audio information to be played back. An index display unit is displayed in a substantially circular playback speed display unit. The amount of audio information to be sequentially played back corresponding to elapsed time is divided by a predetermined value to determine a remainder. The index display unit is displayed at an angular position corresponding to the remainder, while being rotatably moved along a virtual track, thereby displaying the status of playback.

A reproducing system is produced for reproducing music recorded on a digital disc, and a rotating dial is provided to be rotated by a user.

System for reproducing information recorded on a disc

An information playback apparatus is provided to obtain sound effects by using an optical disc in much the same way an analog record is manipulated. A pressing pressure applied onto a rotatable jog dial is detected by providing a pressure sensing layer to the jog dial. When no pressing pressure is applied onto the jog dial, audio information is played back from an optical disc at a normal tempo. When an end of the jog dial at rest is pressed with a pressing pressure within a predetermined range, a tempo of a playback sound played from the audio information is changed in response to the pressing pressure. When an end of the jog dial at rest is pressed with a large pressing pressure, a tempo of a playback sound played from the audio information is changed in such a manner that playback of a playback sound is stopped eventually. When the pressing pressure is released from the jog dial at rest, a tempo of a playback sound played back from the audio information is changed in such a manner that a playback sound is eventually played back at the normal tempo. Also, a tempo of a playback sound is changed in various manners in response to a pressing pressure onto the jog dial by providing manipulation keys for adjusting a quantity of change when changing a tempo of a playback sound in response to the level of a detection signal.

Disclosed is an audio reproduction apparatus for reproducing music information recorded on a digital disk. This apparatus includes a rotatable body, a detection section for detecting a rotational state of the rotatable body, and a processing section for processing the music information to be reproduced in accordance with the rotational state detected by the detection section.
