In the figure, 1 is a teletext data extraction unit that extracts teletext data from a video signal including a teletext signal; 2 is a data analysis unit that inputs and analyzes the teletext data to create screen data;
3 inputs the user's page designation from the operation unit 6, and sends the screen data corresponding to the designation from the data analysis unit 2 to the storage unit 4.
4 is a data storage unit that stores screen data created by the data analysis unit; 5 is a control unit that outputs instructions to be output to the
6 is a data conversion unit that converts the data stored in the data storage unit into a video signal, and 6 is an operation unit that specifies the page number of the screen that the user wants to select and inputs a signal corresponding to the designation to the control unit. .

[0004] The mutual relationship and operation of the above components will be explained. A teletext data extraction section 1 receives a video signal, extracts teletext data contained therein, and outputs it to a data analysis section 2. The data analysis section 2 inputs and analyzes the teletext data, creates screen data of the page number specified by the user on the operation section 6, and outputs it to the data storage section 4. The data conversion section 5 reads out the data in the data storage section 4 and outputs the screen and audio signals to be reproduced. Operation unit 6
The user inputs a corresponding signal to the control unit 3, such as a key input for specifying a page on the screen. For example, when a user wants to select a 120-page screen, he or she enters 1, 2, and 0 in sequence from the operation panel.

[0005]

[Problems to be Solved by the Invention] In such a conventional teletext receiving device, it is necessary to specify the page number of the screen to be selected using three digits from the operation section, and the operation section must always be at hand. It was necessary to input while checking the screen visually. Additionally, teletext was of no use to visually impaired people.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a teletext receiving device that allows easy screen selection operations and can be used by visually impaired people.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a teletext data extraction unit that receives a video signal and extracts teletext data included in the video signal, a data analysis section that analyzes and creates screen data, a data storage section that stores the screen data, a data conversion section that reads out the screen data from the data storage section and converts it into a video signal and an audio signal, and the data The analysis unit includes a control unit that instructs the screen specified by the user, and inputs the user's voice specifying the page number of the screen to be selected, recognizes the voice, and inputs information on the specified screen to the control unit. A teletext receiving device is provided with a voice identification input section.

[0008]

[Operation] In the above configuration, the voice recognition input section inputs a voice specifying the page number of the user's screen selection, recognizes the voice, and inputs a signal corresponding to the specified screen to the control section. . The control unit refers to the designation signal with the screen data output by the data analysis unit, outputs a matching signal to the data analysis unit, and designates the screen. The data converter generates a video signal and an audio signal from the specified screen data.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A teletext receiving apparatus according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of the configuration of a teletext receiver according to an embodiment of the present invention. In the figure, 11 is a teletext data extraction unit that extracts teletext data from a video signal sent from a broadcasting station;
12 is a data analysis unit that creates screen data from the teletext data extracted by the teletext data extraction unit 1;
Reference numeral 6 indicates a voice recognition input unit through which the user specifies and inputs a screen by voice; 13 indicates a control unit that specifies a screen to the data analysis unit 12 in accordance with the screen specified by the voice input unit 16; and 15 indicates the data analysis unit. This is a data storage unit that stores screen data output by the unit 12.

[0010] The interconnection and operation of the above components will be explained. In the above configuration, the configuration and operation of the teletext data extraction section, data analysis section, data storage section, data conversion section, and control section are the same as those in the conventional example, and detailed explanations will be omitted.

A new component in the present invention is a voice recognition input section 16. The voice recognition input unit 16 inputs a voice signal specifying the screen that the user wants to select, uses voice recognition to determine whether the input voice indicates a valid number, and when it is valid, inputs the number to the control unit 13. Enter. The control unit 13 compares the number with the page number of the screen output from the data analysis unit 12 and outputs a matching signal to the data analysis unit 12. The data analysis section 12 inputs the matching signal and outputs the data of the matching screen among the plurality of screen data to the data storage section 14 for storage. The data conversion unit 15 reads out the data in the data storage unit, converts it into a video signal and an audio signal corresponding to the screen, and outputs the converted signal. This audio signal can be produced, for example, by outputting an audio signal that utters the reading of a character from a code corresponding to the character.

As described above, according to the teletext receiver according to the embodiment of the present invention, the voice identification input section is provided so that the user can input the screen selection by voice, thereby eliminating the need to have the input device at hand. Since there is no need for any operation,
Selection operations are extremely easy, and audio corresponding to the text can also be uttered, making it usable even by visually impaired people.

[0013]

[Effects of the Invention] As is clear from the above embodiments, the present invention includes a teletext data extraction section that inputs a video signal and extracts teletext data included in the video signal, and a teletext data extractor that analyzes the teletext data. a data analysis section that creates screen data using a computer; a data storage section that stores the screen data; a data conversion section that reads out the screen data from the data storage section and converts it into a video signal and an audio signal; a voice identification input unit comprising a control unit for instructing a screen specified by a user, inputting the user's voice specifying a page number of a screen to be selected, recognizing the voice and inputting specified screen information to the control unit; By making the teletext receiving device equipped with a teletext broadcast, the screen operation becomes easy and audio corresponding to the broadcast content can be uttered, which has the effect that even visually impaired people can use the teletext.
