ABSTRACT:
A video compression circuit comprises an input that receives an input video signal. A memory buffer, coupled to the input, temporarily stores a portion of the input video signal. A single horizontal filter bank, coupled to the memory buffer, high-pass and low-pass filters horizontal components of the input video signal. A single vertical filter bank, also coupled to the memory buffer, high-pass and low-pass filters vertical components of the input video signal. A recursion buffer, coupled to the filter banks, temporarily stores filter components of the input video signal for recursive filtering.
