Method and apparatus for two-component signal compression. |
摘要 |
<p>A method and apparatus for compressing (in 104) and expanding discrete signals (from 201) is disclosed which comprises two compression methods which interact synergistically. Illustratively, a minimum-redundancy Huffman code, which partially represents a compressed signal, is used in conjunction with a uniquely decodable code which comprises two components. The first component represents its own length, the length of the second component and partially represents the compressed signal and the second component partially represents the compressed signal (from 223). <IMAGE></p> |
