Blocking phenomenon elimination circuit of European HDTV system

摘要

The present invention relates to a HD-MAC decoding unit of a European HDTV system. In the related art, a reconstruction signal processed by an HD-MAC decoder causes a blocking phenomenon at a boundary of a block and causes adverse effects on image quality.;In order to solve the problems of the related art as described above, the present invention provides a block descending removal means (1) for eliminating blocking phenomenon by low-pass filtering the horizontal and vertical components only at the block boundary on the output side of the HD-MAC decoder And to provide a blocking artifact elimination circuit in a European HDTV system of the configuration.
