Abstract:
1. An RF communications system, comprising: a remote control transmitter that includes: a remote control side control unit that generates control data for controlling operation of an apparatus in accordance with an input operation and an RF transmitting circuit unit that generates RF packet data which contain the control data generated by the remote control side control unit and that transmits an RF signal that is modulated with the RF packet data via a transmitter antenna; and a controlled apparatus that includes: an RF receiving circuit unit that demodulates the RF packet data from the RF signal received by a receiving antenna, the RF receiving circuit unit comprising: an apparatus side control unit that receives the modulated RF packet data from the pulse signal modulation unit, demodulates the modulated RF packet data to obtain control data from the modulated RF packet data, and controls the operation of each unit based on the control data that are contained in the modulated RF packet data; wherein: the apparatus side control unit is configured to extract output code data from the demodulated RF packet data and to determine whether the output code data comprises output code data in pulse modulated format or UART format; when the output code data is in pulse modulated format output, the apparatus side control unit retrieves the pulse modulated signal format from the format storage unit, modulates the demodulated RF packet data according to the pulse modulated signal format to prepare a pulse modulated signal, and provides the pulse modulated signal to the pulse modulation signal output interface for outputting; and when the output code data is in the UART output format, the apparatus side control unit prepares the demodulated RF packet data as serial data and provides the serial data to the UART interface for outputting.
