Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a broadcast receiving apparatus and a network connection apparatus.
[0002]
[Prior art]
The Internet and broadcasting have so far developed independently in their own fields, but the mutual relationship between the two has become closer with the progress of information communication technology in recent years. For example, during a broadcast program, introduction of address information on the Internet (hereinafter referred to as “URL”) on a screen or text broadcast, introduction of a program using a program URL, acceptance of a questionnaire, and the like are frequently performed. It is coming. (Refer to pages 218 to 223 of the Nikkei PC March 25, 1996 issue.)
[0003]
[Problems to be solved by the invention]
However, conventionally, when accessing the Internet based on a URL, it has been necessary to register the URL to be accessed using Internet access software (hereinafter referred to as “WWW browser”). For this reason, users of the Internet have to first go through complicated procedures such as writing down a URL that they learned from a broadcast program, etc. on paper, starting a WWW browser, and registering the written URL manually. .
[0004]
An object of the present invention is to provide a network connection device that automatically registers a URL obtained from a broadcast program or the like and allows easy access to the Internet.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the network connection device of the present invention provides:
A network connection unit, and the video signal demodulating means, and teletext decoding means for the separate decoding and displaying the signal teletext signal superposed on the demodulated video signal in the video signal demodulation means, the video signal demodulating means Video signal generating means for generating a video signal from the demodulated video signal and the display signal decoded by the teletext decoding means, and character string extraction for extracting network address information by character recognition of the video signal generated by the video signal generating means And a network access unit that analyzes network address information and selects and accesses a network to be connected.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be specifically described with reference to the drawings.
FIG. 1 is a block diagram showing a preferred embodiment of the present invention.
[0007]
In FIG. 1, a television signal received and selected by a tuner unit is input to an input terminal 1, the input is demodulated by a demodulation unit 2, one is input to a video signal generation unit 11, and the other is text. Input to the broadcast decoder unit 3. The teletext decoder unit 3 separates and decodes the teletext signal superimposed on the demodulated television signal. Via the control bus line of the CPU 7, the teletext decoder unit 3, the ROM 4 storing the control program for the CPU 7, the RAM 5 for storing reservation registration data, the input unit 6 for inputting reservation registration data, the display time and the display time Are connected to each of a RTC (real-time IC) 8 for managing the video, a VRAM 9 for storing the decoded teletext signal, and a display processing unit 10 for converting the decoded teletext signal into a display signal. Control input and output.
[0008]
Further, the tuner unit is controlled by the CPU 7 or a separately provided control means so that the desired channel text broadcast can be received, and the teletext signal decoded by the text broadcast decoder unit 3 is written into the VRAM 10 under the control of the CPU 7. Are temporarily stored, read out, input to the display processing unit 10, converted into a display signal by the display processing unit 10, and input to the video signal generation unit 11.
[0009]
The video signal generator 11 generates a television video signal or a video signal obtained by superimposing a teletext signal on the television video signal. The video signal generated by the video signal generation unit 11 is input to the URL detection unit 12.
[0010]
The URL detection unit 12 detects the keyword of the character string “http: //” from the input video signal by character recognition. When the keyword is detected, the subsequent address such as “www.sony.co.jp/” is stored in the URL storage unit 13 and output to the WWW browser 14. The WWW browser 14 connects to the network 16 based on the input address, and outputs data stored in the server at that address. Information output from the WWW browser 14 is connected to a display unit 15 such as a television.
[0011]
In the case of teletext, the video signal of teletext is sent to the video signal generator 11 via the display processing unit 10, so that the above method can be used.
[0012]
【The invention's effect】
As is clear from the above description, according to the network connection apparatus of the present invention, the URL is extracted from the text information on the screen and text broadcast, and the WWW browser is started and registered. It is possible to easily see the URL that has been set.
