PROBLEM TO BE SOLVED: To synchronize an encoder of a radio transmitter with a decoder of a radio receiver, without requiring complex processing and reducing data transmission efficiency.SOLUTION: A radio transmitter 10A generates a TS packet including a PCR value on the basis of a timer value, at time preceding start time of a PCR time slot by off-set time; and transmits a radio frame including the TS packet including the PCR value, at the start time of the PCR time slot. A radio receiver 20 receives the radio frame including the TS packet including the PCR value, in the PCR time slot, measures propagation time of the radio frame until time when the radio frame is received after the start time of the PCR time slot; calculates the summation of the off-set time and propagation time as delay time of the PCR value; and adjusts a timer value on the basis of the PCR value obtained from the radio frame and the calculated delay time. |
