    摘要: A multi scene recording disk medium on which user information is stored in a specific structure and a reproducing apparatus and method for such medium, which enable a user to selectand switch via a menu between simultaneously proceeding scenes and also enable a program editor to edit programs in a new concept and manner. On the medium multi-scene user information program data representing the scenes is divided into a plurality of program bars, each bar containing consecutive user information program data items comprising frames of video data, the bars being consecutive or interchangeable. The program bars are recorded in a data area of the disk and program bars representing interchangeable user information program data items form a group of program bars. Multi-scene configuration information defining reproduction sequences of program bars and groups of program bars of interchangeable user information program data items is recorded in a management area of the disk, so as to enable the user to switch between program bars being defined to be interchangeable The last frame of video data of a program bar defined in the reproduction sequence to be reproduced preceding a group of program bars of interchangeable user information program data items contains a menu information indicating user selectable information program data items of said group of program bars.

    摘要: The present invention relates to a recording medium, like a magnetic or an optical disk, comprising program data stored in one area; and management information stored in another area and used for managing the program data, wherein said program data includes: a packet of encoded main image data (VIDEO) which is obtained by compressing and encoding main image data and is divisible in units of one frame; and a packet of encoded sub-image data (SUB-PICTURE) which is independent of the main image data, is selectively superimposable on the main image data, and is data compressed and encoded by means of a system independent of a system used for encoding the main image data. This recording medium can efficiently store data of different types (like main image data/video data, sub-picture data, audio data).

    摘要: The present invention relates to an apparatus for accurately synchronizing compressed video and audio signals by using simple means. The apparatus comprises an encoder section whith image grouping/compressing means (202,203,204) for encoding a predetermined number of image frames which corresponds to a predetermined reproducing time of an original image, thereby generating encoded video data items, and for combining the encoded video data items into a video packet, with speech grouping/compressing means (210,211) for processing encoded audio data corresponding to the packet of encoded video data items, thereby generating speech frames, and for combining the speech frames into an audio packet, and with additional data generating means (212,213,214,215) for generating additional data consisting of a speech frame number assigned to that speech frame included in said audio packet which represents an original speech corresponding to a start timing of a specified image frame included in the video packet. A formatter combines the additional data, the audio packet and the video packet into a data unit. The apparatus further comprises a decoder section whith decoding means for decoding the encoded video, audio and additional data of each data unit, and output timing setting means for setting timing of outputting a first specified image frame, when a speech frame number contained in said encoded audio data coincides with a speech frame number contained in said additional data.
