  • Patent number: 6477123
    Abstract: The invention relates to a device for CD reproduction with variable speed or direction, in particular devices compatible with a CD player, such as, for example, DVD players which are likewise suitable for the playback of CDs, or corresponding CD-ROM drives. The invention is based on the fact that the data or information read from the CD are read into a buffer memory at a rate which, as a rule, is higher than is required for real-time reproduction. Data read into the buffer memory (RAM) in a continuous sequence are then used for CD reproduction with variable speed by means of subsampling or oversampling. For the purpose of reverse reproduction, groups of subcode words are successively read from the buffer memory by changing the order within the groups and are reproduced as a continuous reproduction data stream.
