Long-distance printing and receiving of newspapers

Newspaper lectures, printing and distribution lectures

With the continuous development of the news and publishing industry, some newspapers with large circulation, such as People’s Daily, Guangming Daily, Economic Daily, Sports Weekly, and Workers’ Daily, have been established throughout the country or abroad. In India, with the help of high-tech satellite communications, the newspaper's typesetting results on the day of the newspaper can be rapidly transmitted to the printing sites in the field. After receiving the documents, the printing point can immediately send large samples and films, and then punch the film. , printing, printing, printing. In this way, the same kind of newspaper can be listed at almost the same time in newspapers and magazines markets across the country. At present, there are three ways to adopt the edition: satellite edition, telephone edition and broadband network edition. The following focuses on the satellite version of the system.

1 satellite coding system

1.1 Summary

Satellite communication is a modern means of communication that has been rapidly developed in the past two decades. Satellite transmission is favored by the newspaper industry because of its characteristics of fewer links, high reliability, wide coverage, high-speed transmission, and easy expansion.

The satellite copying system consists of a communication system and a copying system. The communication system adopts world-advanced satellite equipment and has reliable performance. The copying software runs under the Chinese Windows98 environment, and the operation is intuitive and simple. The entire system has the following features:

1 high speed and high efficiency. The data transmission rate is 128K, which is sent by broadcast, and it only takes 1 minute to transmit 1M files.

2 reliable and safe transmission. With backhaul verification and ground telephone backup to ensure reliable and safe transmission;

3 The investment benefits are obvious. The construction cost of satellite copying network is low;

4 The establishment of the station is quick and easy. The station construction takes only two days;

5 simple operation and maintenance. The copying software is easy to operate and satellite equipment does not require routine maintenance.

1.2 System Composition

A satellite broadcasting system needs to establish a satellite broadcasting master station and multiple receiving stations that can operate in the C-band or Ku-band.

1.3 Main station software function system composition

1 One-way broadcasting layout. Select the layout file, determine the receiving station, and send the layout data to the local stations at one time;

2 Reissued the broadcast layout. Select all documents and receiving stations at a certain sending time of the day, re-issuing layout files to avoid missing messages;

3 reissue layout data package. Lost packets were reissued for stations that did not receive all layout files.

4 broadcast messaging. Send messages about the work of copying, coordinate the sending and receiving of files between the master station and the station;

5 End of edition notification. The main station informs the station about the layout transmission at the end of each day, ensuring the safety of the station;

6 View broadcasted layout. After sending data to the small station, check the specific sending situation record as needed;

7 Check the send log. Used to view the daily data transmission and reception status of the master station and station saved by the system;

8 Receive station equipment, modify the station station name, station number, latitude and longitude, contact person, telephone, etc.;

9 small station grouping. When it can be used for the other newspapers to publish the edition, the fixed receiving station can be divided to facilitate the operation of the edition.

10 Communication parameter settings: Set parameters such as the number of times to send, time, and path.

1.4 Station Software Features

1 Check the layout reception. View the reception status of the current day layout at any time, and display the files received within a specific time period;

2 Check the broadcast message. Check at any time the messages sent by the main station that are received on the same day and in the past, such as notifications of changes in the time of publication, etc.;

3 Check the end of the notification. View the end of notification sent by the master station, check the layout, time, number of times, and whether the data packet is lost.

4 Check the log. View the data transmission and reception status from master station to station at any time, the system can automatically generate reception log;

5 Communication parameter setting. Set parameters such as station number, working time, waiting time, task retention time, etc.

2 Phone Transcription System Introduction

The essence of telephone transmission is the general computer data communication, which is divided into several steps:

2.1 File Compression

Before you pass the edition, you have to. The S2 file is compressed for processing. This saves time and saves money. In principle, any compression software can be used to compress the file.

2.2 Use of Communication Software

Nowadays, the commonly used communication software is UCCOM. Before using UCCOM, the modem MODEM should be properly connected to the computer. Generally, after purchasing MODEM, there is a communication line that can be connected to the RS232 serial communication interface of the computer. Insert one end of the data cable into the MODEM and the other end into the serial port of the computer, and insert the telephone line into the MODEM. In the socket marked with LINE, the outlet of the telephone is plugged into the socket marked with PHONE on the MODEM, and the program can be entered after the power is turned on.

3 Introduction to Broadband Network Copying System

For a general network, due to bandwidth constraints, it is difficult to transfer a layout containing a large amount of picture and text information to a remote place. With the continuous development and improvement of network technology, it has become possible for printed layouts to realize remote editions via low-cost Internet. First of all, we must introduce broadband network technology in the prepress system. Because broadband network transmission speed is fast, it can realize long-distance transmission and printing in different places.
