    摘要: The present invention provides for an information recording-and-reproducing method and apparatus. At least one play-list file which stores information used for coupling at least two files to each other and for reproducing the files is generated, wherein the at least two files are coupled to each other at the heads and/or midpoints thereof. A first shortcut file is generated for at least one file included in the play-list file, and a second shortcut file is generated for the play-list file. The first shortcut file and the second shortcut file are generated in one and the same folder.

    摘要: A motion image and a still image are selectively recorded onto a recording medium. When the recording of the still image is instructed during the recording of the motion image, one picture plane in the motion image is extracted and stored into a memory. After completion of the recording of the motion image, the image data of one picture plane stored in the memory is repeatedly read out and recorded as a still image. A continuity of motion images to be reproduced is held and a reproduction image of a high picture quality is obtained.

    摘要: First and second digital data to which a code to correct errors was added are inputted. For a certain period of time, processes to detect errors in the first and second digital data are executed in accordance with the order of the first digital data and the second digital data. In this period of time, on the basis of the processing results, processes to correct the errors in the first and second digital data are executed in accordance with the order of the second digital data and the first digital data. Thus, the error detecting processes of the digital data that is inputted on a predetermined unit basis can be executed in parallel and an error correcting process in which a circuit scale is small and costs are low can be realized.
