Abstract:
A method of encoding a digital signal in the form of a stream, which will be decoded later via at least first and second stage buffers, said method comprising the steps of:dividing each access unit defined for each bit stream into a plurality of pseudo access units each having a same predetermined size which is smaller than that of said access unit, in which the size of each pseudo access unit is based on the size of said first stage buffer, a data transfer rate to said first stage buffer and a data transfer rate to said second stage buffer;calculating a time when the inputting of each said pseudo access unit to a respective buffer is completed in response to a time stamp of said access unit and a data transfer rate of said buffer; andconverting each of said plurality of pseudo access units into a packet so that said pseudo access units will be input to said buffer by the time determined by said calculation.
