COMMUNICATION SYSTEM, TUNER, AND SETTING METHOD

摘要

A mobile device includes a signal generating unit that generates a first signal and a transmitting unit that wirelessly transmits the first signal generated by the signal generating unit. The first signal includes frequency information that is used in wireless communication between the mobile device and a tuner. The tuner includes a setting processing unit that sets a receiving frequency of an antenna and a demodulation frequency of a phase synchronization circuit. The setting processing unit sets the receiving frequency and the demodulation frequency on the basis of the frequency information included in the first signal from the mobile device.
