Abstract
An encoding/decoding system to be connected to an external microcomputer, video memory, photoelectric reader or printer comprises an address generator for generating an address to access the video memory word by word, a transition point detector for parallelly processing a video signal word by word to detect a color information transition point address, and execution unit for calculating an address difference from two color information transition point addresses or the color information transition point address based on a difference between two color information transition point addresses, an encoding/decoding table for converting an address difference to a code word and converting a code word to an address difference, and a decoded video signal generator for parallelly reproducing a video signal based on the address difference.
