Abstract

본 발명은 팩시밀리의 에러보정 고속처리 시스템 및 방법에 관한 것으로, 송수신 도중에 에러 프래임이 발생시 송수신을 최대로 단축시키도록 하는 것이다.The present invention relates to a system and method for error correction high speed processing of a facsimile, to reduce transmission and reception at the maximum when an error frame occurs during transmission and reception.

이와같은 본 발명은 입력 송신측의 회상 데이타를 한 블록단위로 저장하는 메인메모리부(3)와, 프로그램롬의 프로그램 수행에 따라 상기 메인메모리부(3)로 부터 출력되는 데이타에서 에러 프레임의 존재 유무를 체크하여 그 결과에 따라 시스템 전체 동작을 제어하는 마이콤(1)과, 에러 프래임 발생시 상기 마이콤(1)의 제어신호에 의해 에러 프레임 이전의 데이타를 메인메모리부(3)로 부터 읽어들여 저장하고 그 저장된 데이타률 출력장치를 통해 프린트 하는 서브메모리부(8)로 구성함으로써, 달성되는 것이다.In the present invention as described above, an error frame exists in the main memory unit 3 storing the recall data of the input transmitting side in units of blocks, and the data output from the main memory unit 3 according to the program execution of the program ROM. Microcom (1) for checking the presence and control of the entire system operation according to the result, and when the error frame occurs, the data before the error frame is read from the main memory (3) by the control signal of the microcomputer (1) And the sub memory section 8 for printing through the stored data rate output device.

Claims

The main memory unit 3 stores, in a block unit, image data of the transmitting side which is demodulated from the modem, and the error frame is stored in the data output from the main memory unit 3 according to program execution of the program ROM. The microcomputer 1 which checks the presence or absence and controls the entire system operation according to the result, and the data before the frame is read from the main memory unit 3 by the control signal of the microcomputer 1 when the error frame occurs. And a sub-memory section (8) for printing the stored data through an output device.

A first step of receiving data of one block on the transmission and reception side and searching for the presence or absence of an error frame; and if the error frame exists as a result of the search, a second step of storing the frame data before the error frame is generated in the sub memory unit; . A third step of decoding and printing the stored data and transmitting a message on an error frame to a transmitting side to re-receive data on the error frame; and a fourth step of searching for the presence or absence of an error frame by searching the received data. And a fifth step of decoding and printing the re-received data and the remaining frames if the error frame does not exist in the fourth step, and determining whether the printed page is one page, and completing the printing if the page is finished. Fast error correction method for a fax characterized in that the step consists of.
