Abstract

PURPOSE:To take out only character information from a received signal and to print out by a printer by detecting the character information from a character information detecting means and turning a selection means on by a character selection means. CONSTITUTION:Received information inputted to a video tex terminal equipment 3 from a picture information center 1 is A/D converted by the modem 8 of an adapter 4 and transferred to a data analysis circuit 9. The data analysis circuit 9 anlyzes the information, when the printing operation is selected, the character information 17 is detected from the code of the head 14 of the respective data and a control code 16 to turn a selection circuit 12 on by a character detection signal 13. Then, the selection circuit 12 transfers the character information 17 to the printer 6 and the printer 6 prints out the inputted character information 17. The character information 17 is simultaneously displayed on a television receiver 7 through a video memory 10 and a display controller 11 from the data analysis circuit 9 together with the information of a graphic channel.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a videotex terminal device.

[Conventional technology]

Conventionally, when printing the information sent from the image information center (image 13 characters), this type of terminal device processed the information by copying the screen, which slowed down the printing speed to the printer, and furthermore, the information sent from the center was Since it contains image information and text information, the image information was printed at the same time.

[Problem that the invention seeks to solve]

■-The conventional Videotex terminal device described above has a hard copy function by copying one screen, but since the received information includes image information and text information, it is not possible to print only text information. First, because of full dot printing, the amount of data transmitted to the printer is large and the printing speed is slow.

[Means for solving problems]

The Videotex terminal device of the present invention includes a character information detection means for detecting character information included in a received signal, and is turned on by a character detection signal outputted from the character information detection means when printing character information. The apparatus includes a selection means for outputting the character information in the received information to the printer, and a printer for printing out the character information input from the selection means.

In this way, only character information can be extracted from the received signal and printed if necessary.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the internal configuration of an adapter 4 included in an embodiment of the Videotex terminal device of the present invention, and FIG. 2 is a block diagram of a Videotex communication system including the embodiment having the adapter shown in FIG. A block diagram showing the basic configuration,
Figure 3 is a diagram of the structure of the data string in the received information, and Figure 4 is the diagram of the data string in the received information.
2 is a configuration diagram showing the data portions of message channel DI (M) and code channel old (C) among the data strings shown in the figure. FIG.

The Videotex communication system is comprised of an image information center 1 that provides various information services, a Videotex terminal device 3, and a telephone line 2 that connects the two. The Videotex 3 receives images and text information pre-stored in the Image Information Center 1 via a telephone line 2 in a conversational manner, and has an adapter 4, a television receiver 4117, and a printer 6 in addition to the telephone 5. are doing. The adapter 4 includes a modem 8 that performs A/D exchange of received data;
A data analysis circuit 9 that has a function of distinguishing between image information and character information in received data and outputs a character detection signal 13 when printing character information, a video memory 10, and a display controller that controls the television receiver 7. 11
and a selection circuit 12 that outputs character information to the printer 6 when turned on by a character detection signal 13. Reception information channels are broadly divided into message channels containing message information, code channels containing command information and character information, and graphic channels containing image information. These channel information are composed of data strings as shown in FIG. 3, and the header 14 of each data identifies the message channel DI (M), the code channel old (C), and the graphic channel DI (T), respectively. It has a possible sign. Figure 4 shows message channel D containing text information.
r(M) and the data part 15 of the code channel or(c), and the codes C8 and C1 of the control code 16 are followed by a standard (indicating whether the data is character information 17 or screen control information 18). It shows. Note that the control code may indicate only the control code.

Next, the operation of this device will be explained with reference to the drawings.

The received information input from the image information center l to the Videotex terminal device 3 is sent to the A/
The data is converted into D and transferred to the data analysis circuit 9. The data analysis circuit 9 analyzes the information, and when the print operation is selected, the header 14 of each data and the control code lG
Character information 17 is detected from the code of character detection signal 1.
3 turns on the selection circuit 12. Therefore, the selection circuit 12 transfers the input character information 17 to the printer 6,
The printer 6 prints out the input character information 17. The character information 17 is simultaneously sent to the graphic channel DI(T)
from the data analysis circuit 9 to the video memory 10 along with the information of
is displayed on the television receiver 7 via the display controller 11.

〔Effect of the invention〕

As described above, the present invention includes a character information detecting means for detecting character information included in a received signal, and a character selection signal outputted from the character information detecting means when the character information is to be printed. , a selection means for outputting the character information in the input received information to a printer, and a printer for printing out the character information input from the selection means, and detecting the character information by the character information detection means as necessary. By turning on the selection means with the character selection signal, it is possible to extract only character information from the received signal and print it out with a printer.
