Abstract:
1. A transmitting apparatus that transmits a radio signal including at least main frame portion of information to a receiving apparatus, the transmitting apparatus comprising: an information main-frame output unit that outputs the main frame portion of information; a storage unit that stores identification information indicating use of the radio signal; a selector that selects a synchronous mode based on the identification information; a reference signal generator that generates a reference signal including a different signal level based on the synchronous mode selected by the selector, and outputs a reference signal component including at least the reference signal; an inserting unit that inserts the reference signal component into a predetermined heading period of the main frame portion of information and at least a part of a blanking period in which a signal component does not exist, and outputs a resulting signal; and a radio transmitting unit that wirelessly transmits the resulting signal output from the inserting unit as the radio signal to the receiving apparatus, wherein a frequency of the transmitted radio signal and a frequency of a process reference clock which is a process reference for the radio signal are synchronized in the receiving apparatus, based on the reference signal component included in the radio signal transmitted from the transmitting apparatus, wherein the selector selects the frequency of the reference signal based on instruction information for instructing whether the reference signal component is inserted and the frequency of the reference signal, and wherein the reference signal generator generates the reference signal with the frequency selected by the selector.
