Method and system for reception of digital television signal

A method for reception of digital television signal applied in a digital television signal reception system, said digital television signal reception system including 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 method comprising:

• receiving at least one digital input signal of television channel at said chip;
• amplifying said input signal of television channel via said low-noise amplifier;
• sending said amplified input signal of television channel to said master receiver and said slave receiver;
• frequency-mixing said amplified input signal of television channel with a signal of a first local oscillator source provided by said master receiver to generate an output signal of first television channel;
• frequency-mixing said amplified input signal of television channel with a signal of a second local oscillator source provided by said slave receiver separate from said first local oscillator source, to generate an output signal of second television channel, wherein a frequency associated with said second local oscillator source is different from a frequency associated with said first local oscillator source;
• and
• executing a digital process in a local-oscillator leakage processing unit to detect and remove from said output signal of second television channel generated by said slave receiver a local-oscillator leakage effect due to said first local oscillator source of said master receiver.
