Abstract:
A digital signal multiplexing method in which plural bitstreams can be multiplexed without buffer rupture at the time of decoding. At a step S1, the time of extracting each accessing unit AU, which is a processing unit prescribed from one bitstream to another, from a buffer to an associated decoder, from input plural bitstreams, is computed. At the next step S2, the constraint time concerning the delivery start time to the buffer of each accessing unit, is back-computed by processing proceeding in a temporally retrogressive direction, using the data of the extraction time of the accessing units AU, and by reading charging of the accessing units to the decoder buffers for the extraction of the accessing units from the decoder buffers. At the next step S3, the schedule of packetizing the accessing units is determined on the basis of the constraint time as found at step S2, by way of performing the scheduling. The plural bitstreams are multiplexed in accordance with the schedule.

Abstract:
A method for encoding a digital signal which is free from overflow and/or underflow of decoder buffer when video and audio data are reproduced while switching a plurality of bit streams from one to another, is disclosed. The method includes the steps of receiving a plurality of digital signal bit streams, detecting sizes of access units, as an encoding unit, of the plural digital signal bit streams, and decode times thereof, comparing the detected sizes of the access units at each decode time, with each other to select a maximum value thereof, providing a virtual stream composed of access units each having a size identical to the selected maximum value at each decode time, and packetizing each of the plural digital signal bit streams, wherein the plural digital signal bit streams are packetized by using padding packets each having a size corresponding to a difference in size between each access unit of the plural digital signal bit streams and that of the virtual stream, when the size of the access unit of the plural digital signal bit streams is less than the size of the access unit of the virtual stream. 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.
