  • Patent number: 6654317
    Abstract: A method for reproducing information, comprising the steps of: reading compressed audio data from an information recording medium in which the compressed audio data is recorded in a frame unit; and subjecting the compressed audio data thus read to an expansion processing to reproduce same. When an instruction is given to make a special reproduction in which a frame region to be reproduced and an other frame region not to be reproduced are mixed, control is made so that the compressed audio data in respective frames are successively reproduced in the frame region to be reproduced, and a header information for the respective frames is read out in the other frame region not to be reproduced, and determination on a leading position of a subsequent frame is made on a basis of the header information, thereby conducting a successive migration for the respective frames.

  • Publication number: 20020101790
    Abstract: An information reproducing apparatus is provided, which has a new cue point setting function with excellent operability for enabling new application form. Specifically, a cue point for specifying a start position for playing back a disc, and additional information or disc identification information corresponding to the cue point are stored in a backup memory. The additional information or the disc identification information is associated with the cue point and shown on a display according to a proper operation of operation buttons and a turning member. When the operation buttons and the turning member are properly operated, a system controller edits and adds the additional information, or edits the disc identification information in the backup memory. When the operation buttons and the turning member are properly operated to enter retrieval information, information stored in the backup memory is compared and retrieved, and the retrieved information associated with a cue point is shown on the display.

  • Publication number: 20010014073
    Abstract: An information reproduction apparatus which can perform repetitive reproduction is provided. In the apparatus, Information read from an information recording medium is decoded by the plurality of decoding devices. Then a source of an output of the information reproduction apparatus is switched among outputs of a plurality of the decoding devices. If a start position to start repetitive reproduction is designated, another decoding device except one decoding device whose output is currently switched as the source is controlled so as to be able to begin to decode the information on and after the start position. Then if a start instruction is provided, the source is switched from the output of the one decoding device to the output of the another device. Further, the another decoding device is controlled to decode the information on and after the start position, and the one decoding device is controlled to be able to begin to decode the information on and after the start position.

  • Publication number: 20010008574
    Abstract: An information reproduction apparatus which can perform repetitive reproduction is provided. In the apparatus, information recorded in an information storage medium is read. Then read information is decoded. Further, the decoded information is stored in a predetermined region of a storage device. During reproduction, information is sequentially read out and outputted in order of precedence at the time of writing the decoded information while the decoded information is stored in the predetermined region. Then, if a start position of repetitive reproduction is designated, a repetition reproduction range is set. The repetition reproduction range is a range that would include the decoded information to be reproduced at one repetition reproduction. Further, the decoded information is maintained in the repetition reproduction range.
