Abstract

Abstract An interleaving method for the presentation of a bitstream that is reproduced by selecting two or more data units from a bitstream comprising three or more data units contiguous on the same time-base. The bitstream is generated by arranging the selected data units in a particular sequence on the same time-base based on the presentation time of each data unit so that it is possible to sequentially access all data units and present only the selected data units without time-base intermittence, and is characterized by dividing the data units into shortest-read-time data units. The bitstream is generated by arranging the shortest-read-time data units in a particular sequence on the same time-base based on the shortest read time in each shortest-read-time data unit so that it is possible to sequentially access all shortest-read-time data units and present only the shortest-read-time data units of the selected data units without time-base intermittence. The presentation time of each shortest-read-time data unit is the same.
