摘要： A digital modulation apparatus applies a method for converting data words to runlength-limited code words using plural conversion tables. The data words are converted to code words that significantly suppress the low frequency component of the final nonreturn-to-zero inverted signal.This digital modulation apparatus includes ROM tables for storing plural conversion tables containing the runlength-limited code words corresponding to the data words; end-runlength memories and evaluators for determining whether the runlength-limit constraints are satisfied in the interconnection between two consecutive code words when the data words to be converted are supplied; and a DSV controller for storing each of the code words that can be selected from two conversion tables to buffer memories when the runlength-limit constraints are satisfied, and selecting the code words wit the greatest effect suppressing the low frequency component in the obtained signal when the code words are NRZI converted.

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： A data transmission method in which data of different types is transmitted and errors detected and corrected optimally for the particular type of data transmitted. A check word is inserted into each group of a plurality of data groups, and a control code is also provided representing the coding method on which the check word is based. The data groups including the check word are transmitted together with the control code. At the receiving end, the control code is separated from the transmitted signal and used to detect the coding method on which the check word is based. Then, error detection and error correction are performed in accordance with the detected coding method.

摘要： A method of recording and reproducing a video format signal on and from a recording medium, wherein the video format signal is reproduced on a two-dimensional picture area divided into sections having predetermined identification numbers respectively allocated thereto, the sections consisting of at least one section for inserting sound information, at least one section for inserting control information and remaining sections for inserting picture information. The control information contains pieces of information indicative of the identification number of the section into which the sound information is to be inserted. The sound and control information is recorded on the recording medium in the form of binary codes each consisting of a predetermined number of bits, each of which is modulated to have its level inverted between every adjacent two bits before the bit is recorded on the recording medium. An occurrence of a burst error is detected through detection of non-inverted bits in the aforesaid binary codes during reproduction of the picture and sound information.
