摘要： A multiplexed stream MBa is formed by multiplexing at step S1. In switching to given ones of N multiplexed streams MBb, buffer occupation information in an end portion of MBa is detected at step S2. At step S3, buffer quasi-amounts in a head portion of the given ones of MBb are detected and the given ones of MBb are formed by multiplexing such that the buffer quasi-amounts are not exceeded. At step S4, a locus of the maximum value of the buffer occupation amounts by the N streams MBb in their end portion is detected. At step S5, a multiplexed stream MBc is formed by multiplexing such that the locus of the maximum value of the occupation amounts is not exceeded.

In accordance with the present invention, there are also provided an apparatus for encoding the digital signal, a method for recording the digital signal on a recording medium, and a method for transmitting the digital signal.

摘要： A method and apparatus for encoding a digital signal in the form of a stream, which will be decoded later via a predetermined number of buffers, in which the digital signal is encoded by dividing each access unit defined for each bit stream into pseudo access units each having a predetermined size, calculating the time when the inputting of each pseudo access unit to the buffer is completed on the basis of the decoding time of the access unit and the data transfer rate of the buffer, and converting the pseudo access units into a packet so that the pseudo access units will be input to the buffer by the time determined by the calculation. If each access unit for each bit stream has a small size and if the decoding interval between adjacent access units is short, a plurality of the access units are combined into a single pseudo access unit depending on the size of the buffer and the data transfer rate of the buffer. The invention also provides a method and apparatus for transmitting similarly obtained data. Furthermore, the invention provides a recording medium for recording similarly obtained data.

摘要： A multiplexing apparatus and method, a transmitting apparatus and method, and a recording medium arranged to prevent a delay of one of multiplexing scheduling processing and multiplexing processing in accordance with a schedule obtained by the multiplexing scheduling processing from influencing the other of these processings. A scheduler calculates schedule information on the basis of access unit information from an encoder and stores the calculated schedule information by supplying it to an intermediate buffer. If some additional data is to be multiplexed, the scheduler also calculates the additional data and stores the calculated additional data by supplying it to an intermediate buffer. A bit stream multiplexer reads out schedule information from the schedule information intermediate buffer, selects data designated by the schedule information from an elementary stream from the encoder and from additional data stored in the additional data intermediate buffer, and outputs the data as a multiplexed stream.
