Method and an apparatus for system encoding bitstreams for seamless connection

An encoding method for producing specific encoded data comprising:

• calculating the data occupancy of a decoding buffer memory of a particular size that is used when decoding the encoded data during reproduction,
• defining the allocated code size of a particular period based on the calculation result, and
• compression coding the signal of a particular period to the allocated code size,
• wherein the data occupancy is calculated on the assumption that virtual encoded data is transferred to the decoding buffer memory following the transfer of first-encoded data to the decoding buffer memory,
• the data occupancy when last data in the first-encoded data is decoded is calculated as a final buffer occupancy Be,
• the data occupancy when the encoding process producing second-encoded data is begun is an initial buffer occupancy Bi,
• the allocated code size is defined based on the change in the data occupancy, and
• the allocated code size is defined such that the final buffer occupancy Be of the first-encoded data is greater than a particular size Bt where Bt>Bi.
