Data communication system and data communication method
First Claim
1. A data communication system comprising:
- a bidirectional cable to transfer data through a high frequency band and a low frequency band;
an antenna to receive an analog data signal and transfer the analog data signal through the high frequency band of the bidirectional cable;
a receiving circuit block comprising;
a receiving module to receive the analog data signal from the high frequency band and converts the analog data signal into a digital data to a host; and
a first control signal processing module to couple a control signal to the low frequency band; and
a function circuit block comprising;
a second control signal processing module to decouple the control signal from the low frequency band; and
a function module to further perform an adjustment on the data communication system according to the control signal.

Abstract
A data communication system and a data communication method are provided. The data communication system comprises a bidirectional cable, an antenna, a receiving and a function circuit block. The bidirectional cable transfers data through a high and a low frequency band. The antenna is to receive and transfer the analog data signal through the high frequency band of the bidirectional cable. The receiving circuit block comprises a receiving module to receive the analog data signal from the high frequency band and converts the analog data signal into a digital data to a host and a first control signal processing module to couple a control signal to the low frequency band. The function circuit block comprises a second control signal processing module to decouple the control signal from the low frequency band and a function module to perform an adjustment on the data communication system according to the control signal.
