    Abstract: An information bit stream having a valid bit stream and an invalid bit stream is acquired. From the transmission data included in the valid bit stream of the information bit stream, some pieces of transmission data are extracted as first transmission data. An information bit stream having a valid bit stream including the first transmission data and an invalid bit stream are outputted as a first information bit stream in which the first transmission data is transmitted at a first speed. From the transmission data included in the valid bit stream of the acquired information bit stream, transmission data other than the first transmission data is extracted as second transmission data. An information bit stream having a valid bit stream including the second transmission data and an invalid bit stream as a second information bit stream in which the second transmission data is transmitted at a second speed is outputted.
