Abstract:
1. A transmission device which selects all or a part of streams from among input streams, and transmits the selected streams as new streams, comprising: a measuring section configured to input an output timing reference signal and an output reference clock required to output the new streams, and when a notice of output start timing is received according to the output timing reference signal, detect the timing, and predict a period in which an output transmission clock to be generated is to be paused; and an output control signal generating section configured to generate the output transmission clock by frequency-dividing by N, where N is an integer of 2 or more, the output reference clock, generate an output timing signal having a constant phase relationship with the output transmission clock, determine at least a part of the period predicted by the measuring section as a paused period, pause generating the output transmission clock during the period, adjust a phase of the output timing reference signal depending on the paused period, and output the output timing reference signal as the output timing signal.
