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.

Claims
