We propose a new image data processing method for MUSE (Multiple Sub-nyquist Subsampling Encoding) signal decoding.In conventional decoding , the moving and stationary areas of the luminance signal are processed separately.Those of the chrominance signal should be processed separately as well.However, this method requires many interpolation and sampling conversion filters and larger hardware.We have integrated these conventional filters into one 2-dimensional filter that has variable tap coefficients.This "integrated filter" has performed satisfactorily in our evaluation for the luminance signal .Furthermore, adapting the tap coefficients of the integrated filter to the chrominance signal of the MUSE signal, an HDTV (High Definition Television) signal is reproduced by using only one 2-dimensional integrated filter.
