Abstract: 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.

Abstract: A reading section (10) reads information recorded in an optical disk and outputs a read signal. A DSP (20) detects the read signal, and make it reproducible. An operational instruction recognizing section (51) recognizes an instruction for a specified position of the information. Then a display control section (54) makes a cue point position display section of a display section (130) display an instructed position. Because of this feature, the specified instructed position can be recognized easily and accurately.

Abstract: The present invention provides an information processing unit with improved operability. A reading section (10) reads information recorded in an optical disk, and outputs a read signal. A DSP (20) 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 (120) recognizes a change instruction for changing a processing state for the information, a reproduction control section (52) changes the processing state by the DSP 20 based on the processing details selected with the quick return button.

Abstract: 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.

Abstract: 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.

Abstract: An audio information reproducing apparatus reproduces one audio information and reproduces another audio information after said one audio information. The apparatus is provided with: a detecting device for detecting one time period required for one beat of said one audio information, and also detecting another time period for one beat of said another audio information; and a reproducing device for reproducing said another audio information continuously to said one audio information while controlling the detected another time period to be coincident with the detected one time period. Alternatively or additionally, the apparatus is provided with: a detecting device for detecting one beat timing which is a timing of a beat of said one audio information and also detecting another beat timing which is a timing of a beat of said another audio information, so that the reproducing device controls the detected another beat timing to be coincident with the detected one beat timing.

Abstract: 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.

Abstract: 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.

Abstract: 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.
