    摘要： The decoder apparatus 90 generates a random number R1 for authenticating the optical disc drive apparatus 70 and sends it to the optical disc drive apparatus 70 as the challenge data CHA1. The optical disc drive apparatus 70 selects one out of the sixteen claimant functions stored in the claimant function unit 722 and calculates the function value fi(CHA1) which it sends to the decoder apparatus 90 as the response data RES1. The decoder apparatus 90 compares the response data RES1 with sixteen function values f1(R1) to f16(R1) that are obtained using the sixteen verification functions stored in the verification function unit 922, and authenticates the optical disc drive apparatus 70 when at least one of the function values matches the response data RES1.

    摘要： An apparatus and a method for reproducing information from a recording disk medium, which recording disk medium includes user information comprising simultaneously proceeding scenes, whereby the program data representing the scenes is divided into a plurality of program bars.
    The reproducing apparatus has means for allowing user controlled switching between interchangeable program bars based on a multi-scene configuration information representing information defining reproduction sequences of program bars read from the disk and stored in a management data storage means, whereby an information processing means is adapted to reproduce a frame of video data of one user information program data item of one program bar, which is currently decoded and reproduced, as a still picture upon user controlled switching to another interchangeable program bar, until a related user information program data item of the other program bar has been read from the medium and decoded.Thereby, switching between interchangeable scenes can be effected smoothly without interrupted display.

    摘要： An apparatus for generating compressed signals, which can serve to record data with high efficiency, to manage data easily, to reproduce programs in a special manner, to search for data at high speed, and to achieve accurate image-speech synchronization. The apparatus comprises a video-data grouping device (103) for processing video data into groups, each consisting of a predetermined number of video data items corresponding to image frames, a video-data compressing device (106) for compressing and encoding the video data items of each group, an audio-data grouping device (102) for processing audio data corresponding to the video data into groups, each group consisting of audio data items, an audio-data compressing device (105) for compressing and encoding the audio data items of each group, a sub-video data grouping device (104) for processing sub-video data into groups, each consisting of sub-video data items, a sub-video data compressing device (107) for compressing and encoding the sub-video data items of each group, a formatter (108) for combining the groups of compressed video data items, the groups of compressed audio data items and the groups of compressed sub-video data items, thereby generating a data unit, data-separating device (121) for separating the compressed data items, a speech decoder (122) for decoding the encoded video data items, an image decoder (123) for decoding the encoded video data items, a sub-image decoder (124) for decoding the encoded sub-video data items, and a synthesizing device combines the decoded video data items with the decoded sub-video data items.
