A video signal processing apparatus and method, and more particularly, digital broadcast signal processing apparatus and method in which channel interference by an analog broadcast is prevented, for effectively removing an analog broadcast signal mixed in a digital broadcast signal of a co-channel, are provided. According to the above apparatus and method, a frequency offset is corrected by operating the frequency offset of a carrier signal and automatically performing fine tuning and the characteristic of an NTSC rejection filter (NRF) is improved by processing the signal whose frequency offset is corrected by the NRF. Accordingly, it is possible to effectively prevent a co-channel interference phenomenon by the analog broadcast from occurring when the digital broadcast signal is processed, to thus reduce noise.
