Encoding / decoding method of digital information gray shape / color

摘要

PURPOSE: A method of encoding/decoding a digital gray shape/color information is disclosed to enable the errorless data transmission. CONSTITUTION: The method comprise steps of: encoding a quantization information of a gray color information; encoding a binary shape information, a DC information of the gray color information, an additional information of the binary shape information and the DC information; encoding a mark signal discriminating the DC information and an AC information; and encoding the AC information of the macro block and an additional information of the AC information.
