摘要： A synchronizing system with a simple structure accomplishes synchronous reproduction without complicating a control circuit for synchronizing video and audio signals with each other. The number of unit audio data blocks to be put in one pack is set in such a way that the difference between the presentation start times for the stream of video data and the stream of audio data in one pack in a predetermined pack period becomes a predetermined value, and the pack carries positional information of the pack in the predetermined pack period to the pack. In a reproducing apparatus, the difference between presentation start times for video signals and audio signals in each pack is acquired by referring to positional information (AAU sequence number) in a stream of packs, transferred by the above transmission method, and at least one of the presentation start times for video signals and audio signals in the stream of packs is controlled so that the difference between the presentation start times coincides with the difference between the presentation start times corresponding to the positional information.

摘要： Method and apparatus of recording and reproducing picture information on a recording medium. In addition to a coded information signal, subcodes together with an identification code for identifying the coding system of the subcodes are recorded in a first recording area of a recording medium. The subcodes are preferably graphic codes including picture information and character codes having predetermined bit patterns, and are decoded in accordance with the identification code at the time of the playback of the recording medium.

摘要： A method and an apparatus for transmitting a video signal. A two-dimensional picture formed by the video signal is divided into a plurality of extracting periods, frames, fields, and areas. A first signal portion represents a moving area. The plurality of areas for each unit extracting period corresponding to successive N (N being a natural number) frames of the video signal. An extracted video signal is formed by extracting from one field the first signal portion in a moving area, and from another field second signal portions representing nonmoving areas. A position identification signal which indicates the position of the moving area formed by the first signal portion are transmitted in combination.
