TEXT/GRAPHIC PROCESSING VIDEO TEX INTERFACE DEVICE

摘要

PURPOSE: To reduce the number of parts to reduce the cost by providing an interface processor only for video tex where various controllers or the like provided in a video tex terminal machine are incorporated in one chip. CONSTITUTION: One color value in the case of read of video data from a video rem connected to a video tex processing part 106 by a system microprocessor consists of four plans. A peripheral selection signal is generated by the processor and is inputted to the processing part 106. Then, a microprocessor interface part 106a of the processing part 106 chip-enables a printer interface part 106c to provide video tex related data. Thus, the interface part 106c prints video tex related data, which is generated in the processor and is inputted through the interface part 106a, by a printer.
