RELAY DEVICE AND RELAY METHOD

摘要

PROBLEM TO BE SOLVED: To transmit a relay signal where influence of frequency variation of a broadcast wave to be received is reduced.SOLUTION: A relay device includes: a reception section 10 for receiving an input signal; a modulation section 20 for generating a modulation signal in response to the input signal; a first clock generation section 30 for generating a first clock synchronized with the input signal; an oscillation section 40 for generating an oscillation signal; a second clock generation section 50 for generating a second clock in response to the oscillation signal; a correction frequency calculation section 60 for detecting a frequency difference between the first clock and the second clock and calculating a correction frequency in response to the detected frequency difference; and a transmission section 70 for generating a transmission signal by correcting a frequency of the modulation signal in response to the correction frequency and transmitting the generated transmission signal.
