Claim Text:
1. A wireless communication system, comprising: a wireless transmitter to transfer a TS packet of MPEG-2 wirelessly; and a wireless receiver to receive the TS packet of MPEG-2 wirelessly, wherein the wireless transmitter and the wireless receiver communicate with each other in synchronization with a predetermined series of time slots, the series of time slots including a PCR time slot allotted to a predetermined number of time slots for transferring a PCR value from the wireless transmitter to the wireless receiver, the wireless transmitter generates the TS packet that includes the PCR value based on a tinier value of the wireless transmitter for a time preceding a predetermined offset time from start time of one PCR time slot, and transfers a wireless frame that includes the TS packet with the PCR value at start time of the PCR time slot, and the wireless receiver receives the wireless frame that includes the TS packet with the PCR value at the PCR time slot, measures propagation tune of the wireless frame between the start time of the PCR time slot in which the wireless frame that includes the TS packet with the PCR value is received and time when the wireless frame that includes the TS packet with the PCR value is received, obtains a delay time of the PCR value from the sum of the offset time and the propagation time, and adjusts a timer value of the wireless receiver based on the PCR value acquired from the wireless frame and the obtained delay time.
