Discussion on Remote Transmission Technology of Newspaper Layout

With the constant development of the newspaper industry and communication technology, more and more newspapers and magazines have carried out off-site excellent printing services. The layout of newspapers and magazines has been transmitted to remote printing sites through various communication methods after printing. At the same time, printing and distributing printed presses all over the country will make information flow faster.

Since the establishment of the laser photocopying workshop in Hubei Province in 1989, the remote newspapers and magazines received through computer satellite communications and regular telephone communications include People's Daily, Economic Daily, Guangming Daily, Reference News, and Half Moon Talk. There are nearly 20 kinds such as "Science & Technology Daily", "China Quality News" and "China Business News". In these newspapers, the communication and copying technologies adopted are computer satellite communication and telephone communication, and the two methods are almost equal to each other. This article analyzes and contrasts two kinds of edition techniques that our society adopts, and analyzes and introduces the telephone to pass edition technology. It is hoped that this article will play a role in attracting investment and provide a reference for the vast majority of Indian newspapers and magazines to carry out business in other places.

Computer satellite transcript technology, with high speed - generally starting at 128KBPS, high speed 256KBPS, 512KBPS, even higher, and stable performance, and can achieve mass (that is, a master station to send the same file to multiple receivers at the same time) Etc.

The establishment of a satellite-based satellite computer system requires the erection of a satellite master station at the sender, the installation of satellite stations at each generation of India, and the rental of a fixed channel to satellite communications companies. The computer satellite transmission system has a large investment and is relatively complex to implement. Generally, a dedicated communication company is used to integrate the entire software and hardware system. In addition, the rental fees for satellite channels are also higher - tens of thousands per year depending on the rental bandwidth. Even more than ten million. Therefore, computer satellite copying technology is only applicable to large-scale newspapers with a certain economic strength that have many printing spots, many layouts, large capacity, and short publishing cycles.

The telegraphic version transmits the information through the ordinary telephone line. The communication parties only need to configure one computer, one modem (or built-in card), one direct dial telephone line and the corresponding telegraph communication software. The telegraphic version has the advantages of small investment, simple configuration, convenience and flexibility. The following focuses on the relevant hardware and software settings in the telephony publishing technology and the comparison and operation of various transcript software.

The application of modems is very common and the installation is very simple. This article will not repeat them here. In the selection of the edition software, each kind of software has its own advantages and disadvantages. The various softwares will be analyzed one by one.

A. Hyper Terminal, Hyper Terminal is WINDOWS98's own communication software. The software is simple to operate and does not require additional settings such as network protocols, IP addresses, dial-up networking servers, etc. The average user can simply increase. The specific operations of the sender and receiver are as follows:

Receiver settings:

1. Click "Start" - "Programs" - "Accessories" - "Communication" - "Super Terminal", the following interface appears:

2. Double icon "hypertrm.exe" appears below (1.tif):

3. Enter a few English letters casually in the "Name" section. Click "OK" to display the next screen (2.tif):

4. As a receiver, you can enter a phone number casually in the “Phone number” column (you can enter the sender's phone number so that the sender can retrieve information). When there is a connection dialing window, as the receiver does not click "dial" but click "Cancel", the main window of the HyperTerminal appears, enter "ats0=1" in the window and press "Enter", there will be "OK". Indicates that the receiver is ready to receive.

Select "Transfer" - "Receive File" in the main menu, select the folder where the received file is stored, and select "Zmodem with crash recovery function" for the receiving protocol.

After everything is set up, you can call the other party to start dialing and file transfer.

Sender settings:

The access method is the same as that of the receiver. When there is a window for entering the phone number, be sure to enter the receiver's phone number (long-distance to add the area code), click "OK", and when the dial-up window appears, click "Dial" to dial up. After the dial-up connection is successful, the connection success icon will appear in the lower right corner of the screen. At this point click on the main menu "send" - "send file", select the file to be sent and Zmodem transmission protocol with crash recovery function, click "OK" on both sides of the screen, the following transmission interface appears:

Second, Bitcom Chinese version Here to BITCOM3.30 Chinese version as an example, the installation is simple, click the SETUP installer, follow the prompts to select the installation directory, modem detection, etc., it is easy to install and set up. After the installation is completed, the program group Bitware Icons will appear. The icon BitCom is the communication software. Double-click the icon to display the communication program interface as follows:

Click the "Phone Book" button to configure the recipient. The following screen appears:

There are two default users in the phone book. Select the following Defaults user for editing. You can change "Defaults" to the recipient's unit name. Other items are set in the following format (A4.TIF):

Set the receiver related settings and related communication settings, then click the "File Transfer" button, select "ZModem" transmission protocol, click "Settings", press the device parameters are as follows:

The "Continuation of file transfer interruption" indicates that the file transfer process is interrupted and will continue to be transmitted from the breakpoint next time. In the main menu "Settings" - "Directory", select the default directory for file receiving and sending.

At this point, both sender and receiver follow the same settings as above. If you are the receiver, select “Settings” under “Host” in the main menu and set the relevant settings as follows (A6A.TIF):

After everything is set up, the recipient can click on the "action" - "auto answer", or "host" - "run host" of the main menu, you can enter ready to receive state.

At this point, the sender can click the "Phone Book" button, select the User who just edited the Defaults, press "Dial", the following pull-up screen (6A.TIF) appears after the connection:

According to a further step, select "U" to send the file to the other party. When the next screen appears, select the "Zmodem" protocol, press Enter, click the "Send" button, or select "Zmodem Protocol" when the next screen appears , select the file name to be transmitted, you can select the file name to be sent one by one and press the "Select" button, so that the file list to be sent will be displayed in the blank box on the right of the window. See the figure below (A7.TIF):

After the file is selected, click the "Send" button to automatically send the file one by one to the other party.

Third, UCDOS UCDOS for the hope that the computer company's early development of the finished DOS operating platform, has been commonly used in the DOS era. The UCCOM program that comes with UCDOS version 7.0 has a telephone communication function. This software does not require a high level of the machine, normal 486, the software works in DOS mode, the installation and setup are very simple. After running UCDOS and starting the Chinese character platform, enter UCCOM. The main UCCOM screen appears. There are several settings such as “Communication Parameters” and “Terminal Parameters” in the “Settings” menu. Set the following items separately:

Communication parameters:

Baud rate - Select 28800, 38400, or 57600 depending on the speed of the modem, 56MBS in general MODEM optional 57600; Data bits -8; Stop bit -1, Parity - No parity; Connection - Depending on the MODEM connection to the host Port and set to COM1 or COM2;

Flow control - XON/XOFF; interrupt request line and I / O base address are selected 0;

Terminal parameters: select one of the five options;

Modem and fax parameters:

Dial mode - audio; select "Machine" answer or "automatic" answer; answer option is "Auto Answer"; "Detect" in the dial tone and busy tone are selected; initialization command must pay attention to the "AT & FQ0VE1 & C1S0 = 0 ";

Transfer Protocol:

All items in "General Options" are selected; one selected in Kermit is "Binary File Transfer Mode (8-bit)"; all ZModem items are selected;

File parameters: The setting under this column is simple and clear. It is the default storage path setting for receiving and sending files.

Auto Navigation Parameter Settings: Select the bottommost "Zmodem" and "Kermit".

After the above items are set, the machine is in auto-answer state, and the other party can use Hyper Terminal or BITCOM or UCCOM for dial-up connection and file transfer; if UCDOS is used as the sender's communication software, just click the menu “Phone”-“Data Machine”. Dial, enter and dial the recipient's phone, the screen will display the other party's machine settings prompt message, then click on the "send file" button, select the file to be sent for file transfer, after the file transfer is complete, click "hang up" Button.

Fourth, FTP file transmission method FTP is the abbreviation of "file transfer protocol". The FTP transmission mode is a file transfer mode of client/server mode. The receiving party installs the FTP server software, and sends the program to install the client software. The recipient can be called "server" and the sender can be called "client". After the customer dials up to the server, the client control software can perform operations such as file access and deletion on the specified folder of the remote server (the server can set corresponding operation permission). This transmission method has the advantages of breakpoint transmission, fast transmission speed and other advantages. If the server terminates multiple program-controlled telephone lines, multiple users can dial in at the same time. At the same time, the above-mentioned and downloading files. The “flying telephony remote copying software” independently developed by our company is such a full-featured and stable FTP copying software. The software is mainly composed of a server, a client, and several configuration files and is directly copied to a folder. You can run it as follows to avoid installation of "green" software. The following describes its use.

Server settings:

1. First of all, make sure you have installed "TCP/IP dial-up network adapter", you can click "Control Panel" - "Network" - "Tianzhong" to install, ensure that "Control Panel" - "Network" has the following "TCP/IP dial-up Network Adapter" item (a00.TIF):

2. Select "TCP/IP Dial-Up Network Adapter", check "Properties", and set the "IP Address" item to "Specify IP Address", which are respectively set as shown in the figure (A11.TIF):

3. The IP address does not have to be set as shown in the figure, as long as it does not conflict with the local area network, nor does it necessarily have the same network as the local area network.

4. Click "My Computer" - "Dial-up Network" in the dial-up network main menu "Connection" - "Dial-up Network Server" appears below (A22.TIF):

5. Select Allow Dial In, set up a dialup password, and the server type is the default value. Restart the machine, you can see a dial-up network server icon in the lower right corner of the screen, indicating that the machine is waiting for the user to dial in.

6. After setting up the previous step, copy the Fringeprint software to any folder (such as C:/chuanban) and run the server-side main program. The following screen appears (A.TIF):

There are four page tabs for "master", "user information", "transmission settings", and "user settings". The following two settings are highlighted here.

Click "Transfer Settings" and the following figure (B.TIF) appears:

The prompts are clear at a glance. Each configuration is set as shown in the figure. The “showing welcome message” and “information when exiting” indicate the relevant information that will be displayed on the screen when the client dials in and disconnects the connection. The information is displayed by the server. The end is sent to the client. The prompt message can be a pre-edited text file. The software can be set to automatically run in the background with the startup of WINDOWS98.

Click "User Settings", the following figure (C.TIF) appears:
