ABSTRACT:
A video signal processing apparatus includes a main picture processor, an interlace recovering module and a video encoder. The main picture processor produces corresponding main picture signals based on video signals from a memory. The main picture signals are converted to progressive scan signals through a predetermined video signals processing. The interlace recovering module receives the progressive scan signals, retrieves the even portion and the odd portion of the progressive video signals alternately, and generates a set of interlace-scan signals. The video encoder receives both the progressive scan signals and the interlace scan signals and generates a set of progressive video signals and a set of interlace video signals to corresponding video display apparatuses. Thereupon, the video reproduction system can simultaneously provide both the progressive video signals and interlace video signals to the video display apparatuses.
