Title: Facsimile broadcasting transmission system and reception system
Inventor: HASEGAWA MASAAKI
IPC: H04N1/00
Filed: 1990-09-12
Abstract: PURPOSE:To decrease a high resolution interpolation information amount and to improve efficiency for transmission and reception by improving efficiency for compressing an interpolating picture in the case of high resolution transmission. CONSTITUTION:For low-resolution first interpolating pictures GII-GIV, exclusive-OR with a low-resolution picture GI is calculated through an arithmetic means 3, and those pictures are converted to second interpolating pictures GII '-GIV' and stored in a divided picture memory. Encoding means 4a-4d converts the respective picture parts GI, GII'-GIV' to facsimile code data compressed by MH or MR encoding, and this facsimile code data is formed into a packet frame by a packet frame generation part 5. Then, by transmitting the interpolating pictures while using the part of a vacant packet so as to satisfy minimum scanning time, ineffective bits as picture information are eliminated. Thus, transmission efficiency is improved.
