PROBLEM TO BE SOLVED: To improve transmission efficiency at the time of transmitting a multiplexed stream and to efficiently utilize the resources of a reproducing device when encoded data such as sound and images are multiplexed. SOLUTION: When the reproducing device side generates a multiplexed stream for synchronizing and reproducing each encoded data with respect to a plurality of pieces of encoded data, the block size of each encoded data is specified through a decoder buffer size inputting part 109 and the maximum number of frames that does not exceed the block size is read from one of the plurality of pieces of encoded data, and when a frame having simultaneousness with the one of the encoded data is read from the other of the plurality of pieces of encoded data, a frame is read within a range where the other encoded data does not exceed the block size. When the frames having simultaneousness are multiplexed, it is possible to read a frame whose time stamp value is smaller than the terminating time of the last frame of the one of the encoded data.
