REMOTE CONTROL SYSTEM CAPABLE OF BIDIRECTIONALLY EXCHANGING DATA BY SIGNAL LINE AND METHOD THEREOF
First Claim
1. A remote control system capable of bidirectionally exchanging data by a signal line, comprising:
- a remote control receiver, comprising a radio frequency (RF) unit, a first core unit, and a first frontend circuit;
a remote control device, connected to the remote control receiver, comprising a second frontend circuit, a second core unit, and hardware; and
wherein, the RF unit transmits a RF signal received from a remote control transmitter to the first frontend circuit via the first core unit to generate a pulse position modulation (PPM) signal;
the second frontend circuit receives the PPM signal from the first frontend circuit and transmits a handshake signal to the first frontend circuit in response to the PPM signal; and
the first frontend circuit transmits a reply signal to the second frontend circuit in response to the handshake signal;
the second frontend circuit transmits an acknowledge signal to the first frontend circuit in response to the reply signal;
after the first frontend circuit receives the acknowledge signal, partial channels connected to the remote control device switches to data exchange mode, and the first frontend circuit encloses setting data and the PPM signal into a formatted packet and transmits the formatted packet to the second frontend circuit;
the second frontend circuit unpacks the formatted packet to obtain the setting data and the PPM signal to transmit the setting data and the PPM signal to the hardware via the second core unit so as to control and set the hardware.

Abstract
The present invention discloses a remote control system capable of bidirectionally exchanging data by a signal line and a method thereof. The system comprises a remote control device and a remote control receiver. The remote control receiver comprises a first frontend circuit. The remote control device comprises a second frontend circuit. The second frontend circuit transmits a handshake signal to the first frontend circuit after receiving a PPM signal. The first frontend circuit transmits a reply signal to the second frontend circuit in response to the handshake signal. The second frontend circuit transmits an acknowledge signal to the first frontend circuit in response to the reply signal. After receiving the acknowledge signal, the first frontend circuit transmits a formatted packet including the PPM signal to the second frontend circuit to control and set the hardware, and then the second frontend circuit sends feedback data to a remote control transmitter.
