Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an information output method, and particularly relates to a system including a voice control device and a terminal device connected thereto. The present invention relates to an information output method for invisiblely outputting information such as the following. ,,.

[Background of the invention]

Generally, it is used as a device for visually outputting information such as characters, figures, images, etc. in a dot pattern.

Display devices such as CRT displays and printers such as line printers, inkjet printers, and wire matrix printers are widely known. The known terminal device is thus equipped with a power loss device. This terminal device is simply used as an output device for offline use.

Recently, an online terminal system is formed by connecting to a host such as a central processing unit or a terminal control device, and characters and graphics are edited and processed by this host.

Data such as images is transferred to a terminal device, where it is output to a display device or printer.

In such known information output systems, conventionally, there have been independent systems tailored to each business, such as a character processing system that handles single character information, a graphic processing system that handles graphic information, and an image processing system that handles image information. forming a system. In other words, a system consisting of a terminal side, a leg device, and a terminal device must be designed separately for each type of text, graphic, and image information.

.

5. In addition, the host program must be conscious of each of the character processing system, system, graphic processing system, and image processing system, as well as the system, and must be designed separately for professionals and durams that handle information such as characters, graphics, and images. No. For example, in a character processing system, it is necessary to create a program to handle only text and information that does not include graphic information (1), which hinders device-independent software orientation. become.

[Purpose of the invention]

An object of the present invention is to provide an information output method that is equipped with a terminal device that can visually output each data of one character, one figure, and one image, and that does not require a control device to be particularly aware of which data to output. There is a thing called K.

[Summary of the invention]

Thus, the present invention is realized in an information central system including a terminal control device and terminal devices connected thereto, such as a character processing terminal, a graphic processing terminal 1, and an image processing terminal. In such a terminal system, the terminal control device has a function of classifying data received from the host into two types of character, two graphics, and two image information and transmitting the classified data to the terminal device. Also, the terminal device receives one character and one figure sent from the terminal control device.

Of the image information, only the data that can be handled by the own terminal device is detected and retained, and other data is ignored.

By using such an information output system, the host program can create a business program that handles 1 character, 1 figure, and 1 image, and output the expected output without being aware of the data processing functions unique to the terminal device. By selecting and connecting a terminal device that matches the output format, for example, whether to output only one character or to output characters and figures, it is possible to configure a system that is suitable for the business.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to one drawing.

FIG. 1 is a block diagram of an information output system to which an embodiment of the present invention is applied. This system is generally comprised of a host 1 such as a central processing unit, a terminal control unit (hereinafter referred to as TCE) 2, and terminal devices 5, 4, and 5 as a plurality of workstations. In this example, these terminal devices are display devices, including a character processing terminal 52, a graphic processing terminal 4. and an image processing terminal 5 are connected to the TCE 2 via a communication line or cable.

The configuration and function of each component block will be explained below.

(b) About TCE2 The host 1 performs various data processing.

The data resulting from the processing is continuously transmitted to the KTCE 21C for output to the display devices 3 and 4.5.

The data format of the text sent from host 1 to TCE 2 is shown in FIG. In this format, a command code (ESC, command) is added next to the well-known text start code STx, and then a control byte CB is added.
The display data continues below. And 1. The text end code ETX is added to the end, and the check food C is added at the end.
, RC are attached. Here, a command is an action to be executed on the display device 5, 4.5.

This is a command to display the data following the command hood on the display device 5, . A WRITE command that instructs "Display on 4 and 5" is considered useful. Further, the control byte CE includes command information for releasing the keyboard lock state of one display device 5, 4.5.

Control byte CE K, followed by display data 9 contain character information (C data), graphic information (C data), image information (I
These data are preceded by a character information header (header C) and a graphic information header (header G) that mark the start of each piece of information.

An image information header (I header) is added to each.

Now, let's go back to the explanation. The text in the data format shown in FIG. 2 is sent from the host 1 to the transmitting/receiving circuit 21 provided in the TCE 2. The transmitter/receiver circuit 21 controls the transmission and reception of data between the host 1 and the transmitter/receiver circuit 21.
A transmitting/receiving buffer 211 is provided within the transmitting/receiving buffer 211 for temporarily storing transmitted/received data. Therefore, the data received from the host 1 is temporarily stored in the transmission/reception buffer 211. After '1, the transmitter/receiver circuit 21 performs a C-, RC check on the received data. If the check result is correct, a reception completion interrupt is issued to the microprocessor (hereinafter simply referred to as processor) 25. On the other hand, if the check result is not correct, an error response is returned to request the host 1 to resend the data.

In TCE'l, the common bus 25 includes a transmitting/receiving circuit 21.
Including, device control circuit 22, processor fuser 25%
A memory 24 is connected. Here, the memory 24 includes a control table 241, a screen memory 242, and an expansion buffer 2.
It consists of 43 pieces. The control table 241 is the display device 5
, 4.5, etc. and the TCE 2, and stores control information indicating the presence or absence of single character data, graphic data, and graphic data. In addition, the screen memory 242 is connected to the display 54°4.
4. Temporarily stores character data among the data displayed on the display screen 54. More specifically, character data corresponds to the display format on the display screen.

and stored as a character code. The expansion buffer 245 temporarily stores graphic data and image data of the display data. Here, one figure data is a command for drawing a circle, a circle, etc. using a known technique. In addition, the image data refers to various patterns that are specifically read using 7-axis IJK, and includes, for example, maps, seals, special patterns, etc., and these patterns are compressed using known techniques such as the MH method. has been done.

The processor 25 performs various data processing to output data received from the host 1 to the terminal device. That is, upon receiving a reception completion interrupt issued from the transmission/reception circuit 21, the processor 25 reads and decodes the data already stored in the transmission/reception buffer 211 one byte at a time.

By this decoding, when a KC header is detected in the data, the following C data is converted into an internal character code and sequentially stored in the screen memory 242. Also, G header and I
When the header is detected.

Subsequent C data and I data are stored as they are in the expansion buffer 245K without being converted.

When all the data set in the transmission/reception buffer 211 has been stored in the screen memory 242 and expansion buffer 245, the C data is transferred to the control table 241.

Set the presence/absence of C data and I data.

The processor 2S activates the device control circuit 22.

Device control row 22 includes TCE 2 and display devices 5.4.
Controls data transfer between terminal devices such as 5 and so on. That is, the control information in the control table 241 and the screen memory 2
C data in 42, G data in expansion buffer 245/
Controls reading and transferring I data.

Here, the control table 241 and the expansion buffer 245 play a characteristic role on the main side. The control table 241 stores control information indicating the presence or absence of C data, C data, and I data as a result of decoding data received from the host 1. For example, it has an area of S bytes, and the first byte is information indicating the presence or absence of C data.
)+4 indicates no C data, (F F )+
4 indicates that C data is present. Similarly, the second byte is information indicating the presence or absence of C data, and the fifth byte is information indicating the presence or absence of I data. In addition, the processor 25
The data and G data/I data are identified, and as a result, the G data/I data is stored in the extension buffer 245 and transferred to the extension buffers 425' and 525 of the terminal device.

(b) Display device (character processing terminal) 5&C In this example, the character processing terminal has a function of displaying a character, such as a sentence C, on the display screen, as shown in FIG. 4(α)K.

In the display device 5, the common bus ARK is connected to the transmitter/receiver circuit 51.
．． Memory 32. Processor 55. keyboard adapter 5
6th grade is connected. The transmitting/receiving circuit 51 controls data transfer with the TCE 2 via the device control circuit 22. The memory 52 has the same configuration as the memory 24 in TCE2, but does not have an expansion buffer.
It consists of a control tape 521 and a screen memory 522. The contents of the control table 241 received from the %TCE2 via the transmitting/receiving circuit 51, that is, C data, C data,
I data presence/absence control information is stored in the control table 521, and C data, ie, character code, which is the content of the screen memory 242, is stored in the screen memory 522.゛Here, the display device 3 is a character processing terminal.

There is no special need for an expansion buffer for storing G data/I data, and the transfer data from the expansion buffer 245 of %TCE2, that is, the C data and I data, are discarded, and only the C data is stored in the screen memo 1522K. The contents of this screen memory 322 are controlled by control information in a control table 521.

It is converted into a dot pattern by the display control circuit 55 and displayed on the display 54.
displayed on the display screen.

When all the data is stored in the memory 52, the transmitter/receiver circuit 51 issues an interrupt signal indicating completion of reception to the processor 55.

The processor 55 controls the display within the display device 5 and controls the input of data from the keyboard 57. In particular, when the interrupt signal is received, the display control circuit 53 is controlled according to the control information stored in the control table 321.

Normally, when using the 1 display 34, a keyboard 57 is required as an input means. Therefore, a keyboard 57 is connected to the common bus 58 via a keyboard adapter 36.

Now, the display control circuit 55 will be explained with reference to FIG. FIG. 5 is a block diagram mainly showing the flow of data, and the same parts as in FIG. 1 are given the same reference numerals. Here, the display control circuit 55 is indicated by a dashed line in the display device 3. The display control circuits 115 and 55 in the display devices 4 and 5 are basically the same. Now, the display control circuit 55 receives an address from the memory 521C in order to read out the information in the control table 521 and the screen memory 522. This address is sequentially updated by the dot counter 554, and character codes are sequentially read out from the one-screen memory 322 and sent to the one-character generator 351. This display control section 555
also sends a synchronization signal to character generator 551 and display 54. That is, in response to the character clock from the dot counter 354, it generates an address signal for the screen memory 4% 22, a rask address signal for the character generator 531, and also generates horizontal and vertical synchronization signals for the display 54. Normally, this display control circuit is equipped with an oscillator 565, and based on the timing signal from this oscillator 555, the count timing of the dot counter 554 is determined by 1 o 5 □, 6 degrees.
“9niy9” The dot counter 534 operates based on the timing signal.
Repeat the counting operation, for example, A1. .

When the pattern is composed of 7 dots vertically by 5 dots horizontally, it is initialized every time it counts 5, and a signal is sent to the display control section 355. The display control unit 555 updates the one screen memory 522 every time a dot is input, and reads character codes one after another.

As is well known, the character generator 551K has character patterns that can be displayed and output. In this example, the character pattern is 1.
It is stored as a do-do pattern □ with a character stroke length of 7' x width of 5.

Character patterns corresponding to the character food output from 522 are sequentially output, and the shift register 5! S
2K will be temporarily suspended.

The shift register 552 stores character patterns (e.g., 80 characters/line) for the display, and these character patterns are sequentially shifted and outputted from the display 544C. Note that the output timing of the character pattern output from the character generator 551 and the shift register 5
The shift timing within 52 is determined by the display control section 333 and the oscillator 555. controlled by

(→ Display device (graphic processing terminal) 4) In this example, the processing terminal has the function of displaying at least the figure G. Specifically, as shown in Fig. 4, (b) K. K
, a figure G such as a pie chart, and a character C can be displayed.

In this display device 4, the technology for creating a character pattern is similar to that of the display device 5 shown in FIGS. 1 and 3. Therefore, the internal differences will be explained below.

The display device 4 has an expansion buffer 425 and a full dot memory 424. The full dot memory 424 is a memory that stores information to be displayed in bits. T
, C'E2 via the transmitting/receiving circuit 41, that is, the identification control information of C data, C data, and I data is stored in the control table 421. Also.

The contents of the screen memory 242, that is, the C data are stored in the screen memory 42.
The contents of the extension buffer 245, that is, C data and I data, are stored in the extension buffer 425. When all the data is stored in the memory 42 as described above, the transmitter/receiver circuit 41 issues an interrupt signal indicating completion of reception to the processor 45.

The processor 45 extracts the control information from the control table 421 and makes a 2 determination. Then, if C data is present, the data stored in the expansion buffer 425 is decoded.

As shown in FIG. 2, the expansion buffer 425 stores data in the format of G header, C data, and I header and I data.

The processor 45 decodes the data in the expansion buffer 425 one byte at a time, and upon detecting the G header, decodes the first subsequent C data, ie, the graphic command, and generates a corresponding graphic square pattern. The generated graphic pattern is stored in full dot memory 424. Since the display device f4 is a graphic processing terminal, it can only process and display C data and C data, and even if it detects an I header, the I header and the following I data are not processed and are discarded.

In this way, the C data, that is, the character food, is stored in the screen memory 422, and the C data is converted into a graphic pattern and stored in the full dot memory 424. Display device 4
has a display control circuit 45 similar to that of the display device 5, and the C data in the one-screen memory 422 is stored in the display device 5.
The character pattern is converted into a character pattern and outputted to the display 44 in the same manner as in the above operation. The graphic patterns developed in the full dot memory 424 are sequentially output to the display 44 in accordance with the rask address signal sent from the display control section 4!115. In this case, the character pattern of C data and 1
The graphic patterns are logically summed and output to the display screen of the display 44.

B) The image processing terminal displays images on the display device (image processing terminal) 5. In the case of this example, not only one image I but also a figure G and a character C are displayed as shown in FIG. 4 (cl K).

1 and 5, the display device 5 is compared with the display device 4Vc, especially the graphic command full buffer 5.
The difference is that it has 25.

This display device 56 (because it is an image geography terminal, handles a large amount of image data, and is capable of transmitting and receiving image data to and from the host 1 via the TCE2).

In general, this buffer 525 is 64 B - number 100
It has a capacity of fJ.

The processing operation is basically the same as that of the musical notation display device 4. TCE 2nd control unit table 241, expansion buffer 2

Process as shown in step 5. In other words, the C data sent from the expansion buffer '245 of TCE2 and! Data is stored in buffer 525 one after another via expansion buffer 525.

The data stored in the buffer 525 is decoded byte by byte by the processor 55, and the C data following the G header is converted into a graphic pattern as described above and stored in the full dot memory 524. The I data, which is stored in the VC and compressed, is decompressed by a known method to form an image pattern and stored in the memory 524 as well.

In this case, the character generator 551 outputs a character rack pattern from the display control circuit 530, and the graphic pattern and image pattern t output from the full dot memory 524.
-i is logically summed at the rear of the shift register 552 and displayed on the display 5.
Supported by 4.

Next, the overall operation will be explained with reference to FIG.

(Operation of cl TCE2 Upon receiving the text shown in FIG. 2 from the host 1, the processor 25 detects the identification control information and sends the C data,
Identify C data and I data. The C data is converted into an internal character code and stored in the screen memory 242. The C data and I data are not converted and are stored as they are in the expansion buffer 24S together with the G header and I header.

All data is decoded and the memory 242. When the storage in the buffer 245 is completed, the identification control information of each data is set in the control table 241 and transferred to the terminal device 5, 4.5.

(A) Operation of the display device 5 Among the information transferred from the TCE 2 in the format shown in FIG. 2, the header, that is, the control information is stored in the control table 521
The C data is stored in the screen memo IJ522K. Incidentally, since this device does not have a particular memory for storing C data and I data, these transferred data are discarded.

Next, the processor 55 refers to the control information in the control table 521 and controls the 1 display control circuit 55 if it identifies that it is a %C header. Then.

The C data, that is, the character code stored in the screen memory 522 I/C is sequentially read out and one character generator
It is converted into a character pattern by the shift register 552.
A display 54 is provided via the display.

As a result, the display screen of the display 1 54 is shown, for example, in FIG.
)K will be displayed.

(cl) Operation of the display device 4 As described above, among the information transferred from the TCE 2 in the format shown in FIG.
is stored in Also, %C data is screen memo I7422
The K, C data and I data are temporarily stored in the expansion buffer 425.

When the processor 45 refers to the control information in the control table 421 and detects the %C header, it operates in the same manner as the display device 5 described above. That is, character codes, which are C data, are sequentially read out from the screen memory 422 and converted into character patterns.

For example, on the display screen of the display unit 44, as shown in FIG. 4(h) K 7F
, FRSA annual budget" is displayed in text.

On the other hand, when the processor 45 detects a G header as control information, it sequentially reads C data from the expansion buffer 423 and creates a graphic pattern according to this C data. C
The data is 5 graphic commands, each of which specifies a different graphic. Therefore, processor 4
5 is.

This command is parsed by known methods and a graphical pattern is generated accordingly. This generated pattern is bit expanded and stored in the full dot memory 424.

The character pattern and the graphic pattern are combined and displayed on the display screen, for example, as shown in FIG. 4(h).

Note that since this display device 4 only has the function of displaying figures and characters, the processor 4
5 detects the I header as control information, the I data in the extension buffer 425 is not processed and is discarded.

Control information in the format shown in FIG. 2 is stored in the control table 521.
C data is stored in screen memory 522, and C data and I data are stored in expansion buffer -y.
52s K is stored as described above. Furthermore, the display operations for single character patterns and graphic patterns are also the same as described above.

Now, when the processor 55 detects the I header in the control table 521, it sequentially reads the I data from the expansion buffer 525 and converts it into an image pattern.

Since the I data is normally transferred and stored in a compressed manner, the processor 55 decompresses the I data using a known method to create an image pattern. As a result, one image pattern created is stored in the full dot memory 24.

In this case, the full dot memory 524K stores graphic patterns and image patterns formed into dot patterns.

The characters and image patterns generated by the spring display circuit 55 are combined and provided to the display 54, and the result is displayed, for example, as shown in FIG. 4 (clK).

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications or applications.

For example, the terminal device connected to the TCE 2 may be a printer instead of the display device Ka, and the present invention can be easily applied even if the number of connected devices is increased.

Further, the display device can be used not only for CRT displays but also for various types of known display devices such as liquid crystal displays and plasma displays.

Also, if one customer terminal device is directly connected to the host,
The host 1 can have the terminal control device 20 function.

〔Effect of the invention〕

According to the present invention, the configuration of the terminal system allows terminal devices that process each data of characters, graphics, and images to be arbitrarily connected to the terminal control device, and the connection of the terminal devices can be freely changed according to the business. and.

The terminal device processes only the data that it can handle out of two characters, one image, and one image, and processes the other data, so the host program can process characters without being aware of the data processing functions unique to the terminal device.

Business programs can be created by handling graphic 1 images.
