Abstract
The present invention provides a digital television signal reception system, comprising a chip having a low-noise amplifier and a master receiver, at least one slave receiver, and at least one local-oscillator leakage processing unit. The chip receives at least one digital input signal of television channel. The low-noise amplifier amplifies and sends the input signal of television channel to the master/slave receiver. The input signal of television channel is frequency-mixed by the master/slave receiver so as to output an output signal of second television channel and an output signal of second television channel. The local-oscillator leakage processing unit detects and removes local-oscillator leakage of the master receiver included in the output signal of second television channel, so as to avoid interference of the local leakage of master receiver on sensitivity of receiving the output signal of second television channel of slave receiver by the slave television.
