PURPOSE:To curtail transmitting and receiving circuits, a connector, etc. by constituting the titled system so that a data signal, timing position information and frame position information can be transmitting by one piece of signal line by a simple processing. CONSTITUTION:The titled system is provided with a transmission side burst conversion processing circuit 91 for converting an input data to a burst data by an N multiplying clock (NXfHz) at the transmission side, and also, generating a clock (N multiplying clock) for executing a superposition on a time base with the burst data, a transmission circuit 93 for executing superposition processing on the time base with the burst data, a receiving circuit 94 for extracting a timing wave from a received waveform and discriminating the burst data contained in the received waveform, and a reception side burst conversion processing circuit 92 for executing a processing reverse to that of the circut 91 of the transmission side. In such a way, by using a superposition transmission system on the time base of the N multiplying clock and the burst data, the timing wave can be extracted from the received waveform at the reception side.
