Abstract: A wireless relay system (1) comprises a wireless camera (11) and a reception relay station (12). The reception relay station (12) comprises a plurality of external reception units (13) arranged at spatially different positions and an internal reception unit (14). Each reception section (16) in the internal reception unit (14) demodulates a signal received in the external reception unit (13) and outputs a transport stream. At this time, each reception section (16) sets an error indicator flag to 1 for a TS packet causing a transmission error which exceeds the error correction capability. A TS synthesizer section (17) in the internal reception unit (14) completely synchronizes a plurality of input transport streams by referencing synchronization bytes, PID, and CC values, and selects to output a TS packet having the error indicator flag not set to 1.
