Abstract:
1. A method for video signal processing, wherein the following steps are performed: receiving an input video signal having a first or input format, said input format having a predetermined standard field rate; processing a modified video signal, which is a derivative of said input video signal, using a video signal processing method, which is designed for processing video signals of a fixed second or processing format thus generating a processed video signal, wherein said processing of the modified video signal is performed with said predetermined standard field rate, and wherein said processed video signal and said modified video signal have said predetermined standard field rate; and outputting a derivative of said processed video signal as an output video signal, wherein said modified video signal is derived from said input video signal by adding or removing pixels to/from said input video signal, thereby obtaining said modified video signal with an intermediate format, if said first or input format does not conform to said fixed second or processing format, and wherein said output video signal is derived from said processed video signal by accordingly removing or adding pixels from/to said processed video signal thereby obtaining an output video signal of said first format, if said first or input format does not conform to said fixed second or processing format.
