摘要： The objectives of the present invention are to reduce the throughput required for a rapid reproduction or other special types of reproduction and to improve also the data access speed at the time of a rapid reproduction. In order to achieve these objectives, the system controller 19 controls so that the address information of the MPEG data reproduced by a pickup 2 may be used to create the first reproduction control information at a sector detection circuit 4, that the second reproduction control information corresponding to the starting point of pictures contained in the MPEG data destined to be reproduction signals by the first reproduction control signal and subjected to an error correction in an error correction circuit 7 may be created in a stream detection circuit 9, and that some MPEG data out of the entire MPEG data may be outputted for a rapid reproduction by referring to the second reproduction control information, and through these steps, the interval of reproducing I pictures in a rapid reproduction by using for example only I pictures is reduced and a smooth reproduction is achieved.

摘要： In a digital VTR having a certain recording bit rate, within a range not higher than a remaining data rate after recording the bit stream, first HP data D1 is recorded in first specific regions, and second HP data D2 is recorded in second specific regions in specific tracks. In middle-speed and high-speed fast replay, the magnetic tape is transported continuously at a middle-speed or high-speed higher than the standard speed for normal replay, and the first HP data D1 is used in common, and at a low-speed fast replay of about twice the normal speed, the speed of the magnetic tape is alternated between a speed near the standard speed for normal replay, and a speed near the low-speed fast, and at the speed near the standard speed, the second HP data disposed in the second specific regions in the specific tracks and the first HP data disposed in the first specific regions in the specific tracks are both replayed.

摘要： At a storage section, picture information of intermediate resolution and picture information of low resolution are formed on the basis of picture information of high resolution which has been read out from a frame memory. These picture information are caused to undergo fixed length encoding at a compression/expansion circuit. These picture data of three kinds of resolutions which have been caused to undergo fixed length encoding are respectively recorded in the order of reproduction and continuously onto an optical disk having tri-sected recording areas for respective resolutions. Thus, it is sufficient to read out, from any one of the recording areas, picture data of resolution corresponding to the equipment which outputs picture data. In addition, since the picture data of respective resolutions are continuously recorded in the order of reproduction, the seek time is eliminated thereby contributing to realization of high reproduction speed.

摘要： An apparatus and method for reproducing data from a recording medium includes a reproducing unit reproducing data from a medium, each data including an identification number corresponding to said each data; a decoder including an internal memory, storing the data from the reproducing unit in the internal memory, decoding the data stored in the internal memory, and generating a first signal indicating that the internal memory is full; and a controller receiving the first signal from the decoder, generating a jump signal to the reproducing unit based on the first signal to move a reader of the reproducing unit from the current position to a predetermined prior position on the medium, generating a second signal to the decoder for instructing the decoder to stop storing the data from the reproducing unit, and generating a third signal when the reader reaches the current position on the disc from the predetermined initial position. The third signal instructs the decoder to resume its storing process in the internal memory of the decoder.

摘要： An image information decoding and reproducing apparatus and method reproduces images in reverse sequence when a plurality of images is compressed to a single image unit and recorded to a disc-shaped recording medium. When the j-th picture from the beginning of an i-th access unit is reproduced, an image information reading section reads the two access units from (i-1)th access unit to i-th access unit, an image decoding section decodes images, and a decoded picture counter counts the number of pictures decoded after the counter has counted a particular value, e.g., 2. An image output section then outputs the picture decoded when the count detected by the decoded picture counter reaches a particular value. Reverse sequence reproduction is thereafter achieved by successively reducing the values of j and i.

摘要： The invention provides a a recording data production apparatus and method, a recording medium reproduction apparatus and method and a recording medium by which interruption of data can be prevented even when reproduction of data is performed in a different order from the order in which the data are recorded. When it is intended to allow reproduction of data in an order of a block A, a block B and a block D or in another order of the block A, a block C and the block D, in order to prevent underflow of data from a buffer memory of a reproduction apparatus, the block B is sectioned into sections B.sub.1 to B.sub.3 and the block C is sectioned into sections C.sub.1 to C.sub.3. Then, the lengths of the sections are set to a predetermined value, and the blocks are arranged in an order of the blocks A, B.sub.1, C.sub.1, B.sub.2, C.sub.3, B.sub.3, C.sub.3 and D. In each section, addresses of a jumping start point and a jumping destination are recorded as control information.
