Abstract
The design of a video processing core designed for processing video signals of a specific video format requires a high expense. It is therefore desirable to be able to use such a video processing core for other video formats as well. The invention therefore provides the method for video signal processing, wherein the following steps are performed: receiving an input video signal (1) having a first or input format (INOUT, NTSC; INOUT, PAL), processing said input video signal (1) or a modified video signal (2), which is a derivative of said input video signal (1), using a video signal processing method, which is designed for processing video signals of a fixed second or processing format (PAL; NTSC) thus generating a processed video signal (3), outputting said processed video signal (3) or a derivative thereof as an output video signal (4), wherein said modified video signal (2) is derived from said input video signal (1) by adding or removing pixels to/from said input video signal (1), thereby obtaining said modified video signal (2) with an intermediate format (PROC), if said first or input format (INOUT, NTSC; INOUT, PAL) is not conform to said fixed or processing second format, w…
