摘要： Embedded proprietary data, which is configured by embedding decoding key data for decoding encoded contents into proprietary data that is a subject of ownership, is recorded on a recording medium. Since the decoding key data is embedded into the proprietary data, it is difficult to separate and take out the decoding key data from the proprietary data. When copying or the like including the proprietary data is performed, it becomes possible to legally pursue a copy or the like of the proprietary data.

摘要： A burst error-correcting capability is largely improved. At least the even-number row and at least the odd-number row of the data block which is a set of data sectors are separated. An outer parity is created for each column and an inner parity is created for each row. Then, the outer parity is scattered with respect to each of the sectors of the data block to be interleaved.

摘要： Data on multiple stories or scenes are recorded on a recording medium so as to reduce the physical distance moved by a pickup at playback time and to suppress breaks or disturbances in reproduced video. A multi-scene program having a plurality of optionally selectable branch stories B0, B1, B2, B3, etc., is recorded between a branch point X and a connection point Y. The preceding main story of a video program, made up of video, sound, text and the like, branches off at branch point X to the branch stories, and at connection point Y connects to the succeeding main story in the video program. The recorded state between the branch point X and the connection point Y is such that the branch stories are each divided into multiple cells and the cells of the respective branch stories are recorded time-division multiplexed.

摘要： A transmitting method of digital data whereby information data can be reproduced at a high precision. In order to retain digital data in sectors comprising a plurality of sync frames and sequentially transmit, the sync frame is comprised of the sync signal and the run length limited code which satisfies the limitations of the minimum run length and the maximum run length, and the sync signal includes the sync pattern constituted by a bit pattern of a run length that is longer than the maximum run length by only 3T and addition bit patterns which are arranged before and after the bit pattern and each of which has a run length that is longer than the minimum run length. The sync signal includes a specific code which indicates a position in the sector and which enables the DC control to be performed.

摘要： A data transmission apparatus for transmitting an original data has a converter for converting the original data to sequential data codes. The data code is formed by a combination of HIGH level binary codes and LOW level binary codes. The maximum length of a continuous binary codes of one level, such as HIGH level, in the data codes is limited to T.sub.max, e.g., to 14T, in which T is a unit length representing one binary code, and the minimum length of a continuous binary codes of one level, such as HIGH level, in the data codes is limited to T.sub.min, e.g., 3T. A generator generates a synchronization code. The synchronization code is formed by a combination of HIGH and LOW level binary codes. The synchronization code comprises an identifier having a continuous binary codes of one level, such as HIGH level, with a predetermined length 16T which is 2T greater than T.sub.max. An inserter inserts the synchronization code intermittently in the sequential data codes.
