A method for pre-processing block-based digital data that pre-processes each digital pixel based on a respective data filter arrangement or data filter matrix for a respective data pixel within at least one data block and selects, constructs, and/or supplies the data filter arrangements or data filter matrices. The method is based on operations of data shifting and/or register shifting only.

Method for pre-processing block based digital data

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 () having a first or input format (INOUT, NTSC; INOUT, PAL), processing said input video signal () or 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 (PAL; NTSC) thus generating a processed video signal (), outputting said processed video signal () or a derivative thereof 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 (PROC), if said first or input format (INOUT, NTSC; INOUT, PAL) is not conform to said fixed or processing second format, 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 (INOUT, NTSC; INOUT, PAL) is not conform to said second or processing format (PAL; NTSC).
