DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information providing system for providing information to a viewer during a radio broadcast time or a television broadcast time.

[0002]

2. Description of the Related Art During a radio broadcast time or a television broadcast time, there are relatively many information and items that a viewer wants to write down. Such information is a lot of information to memorize, and if it is written down, a shorthand technique is required.

[0003] For example, recipe information and cooking technical information in a cooking program are information that the user wants to write down, but is much information to store. Obtaining such information in a printed state in real time increases the convenience for the viewer.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides information capable of outputting information during a radio broadcast time or a television broadcast time to a viewer in real time. The purpose is to provide a system.

[0005]

The gist of the present invention is that a fixed pattern signal is detected from a video signal obtained by multiplexing a fixed pattern signal, and facsimile data relating to the video signal is given to a specific subject at the timing when the fixed pattern is detected. Is transmitted, whereby information during a radio broadcast time or a television broadcast time can be output to a viewer in real time.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An information providing system according to a first aspect of the present invention comprises: a pattern signal detecting means for detecting a fixed pattern signal from a video signal in which a fixed pattern signal is multiplexed within a predetermined period; Transmitting means for transmitting facsimile data relating to the video signal to a specific subject at the detected timing.

[0007] According to this configuration, since the temporary information of the voice and the image can be combined with the permanent information of the printed matter, the qualitative and quantitative effects of the information provision can be increased.
It is possible to respond to the recording needs of the viewer in a timely manner.

A second aspect of the present invention, in the information providing system according to the first aspect, adopts a configuration in which a fixed pattern signal is multiplexed in a character signal superimposable period of a vertical blanking period in a video signal.

According to this configuration, a fixed signal, which is a transmission timing signal, can be multiplexed with a video signal without affecting transmission and reproduction of the video signal.

According to a third aspect of the present invention, there is provided an information transmitting apparatus comprising: a pattern signal detecting means for detecting a fixed pattern signal in a video signal; and information for extracting information corresponding to the video signal at a timing when the fixed pattern signal is detected. A configuration including an extracting unit and a transmitting unit that transmits the extracted information by facsimile is adopted.

[0011] According to this configuration, the persistence information of the printed matter relating to the television program or the radio program can be transmitted in real time, that is, at the timing desired by the viewer.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram illustrating an information providing system according to an embodiment of the present invention. FIG. 1 shows a configuration of an information transmitting device in the information providing system. In the present embodiment, a case will be described where the information to be provided is recipe information in a cooking program.

In this information transmitting apparatus, the video signal and the audio signal of the cooking program transmitted from the cooking program transmitting apparatus 101 are transmitted from the television transmitter 102. In the video signal transmitted from the cooking program transmission device 101, a fixed pattern signal included in the video signal is detected in the recipe transmission timing detection device 103.

The FAX transmission control unit 105 reads out, from the recipe database 104, recipe information corresponding to the content of the video signal at that timing according to the detected fixed pattern signal timing. This recipe information is transmitted by facsimile to the FAX 108 registered in advance via the PSTN 107 by the FAX transmission device 106.

Next, the operation of the information providing system of the present invention will be described. First, as shown in FIG. 2, the audio signal and the video signal of the cooking program content are recorded by the recording device 202. In this case, the fixed pattern signal is multiplexed in the recipe sending timing multiplexing device 201 for the video signal.

As shown in FIG. 3, the fixed pattern signal thus multiplexed includes a unique word 301 which is a synchronous code, data 302, and a CRC which is an error correction code.
(Cyclic Redundancy Check) 303.
The data 302 includes a program content number, a recipe number, a page number, and the like. Then, recipe information corresponding to these numbers is stored in the recipe database 104.

As a period for multiplexing the fixed pattern signal as the transmission timing signal, for example, as shown in FIG. 4, a specific period 401 in the character signal superimposable period in the vertical blanking period is exemplified. Can be.

[0018] These multiplexed video signals are reproduced by the cooking program transmitting apparatus 101 together with the audio signals. This video signal is sent to the recipe sending timing detecting device 10.
At 3, the transmission timing is detected. This detection is performed by detecting a fixed pattern signal multiplexed on the video signal. At this time, the recipe sending timing detection device 103 also detects the content of FAX transmission and the like.

The FAX transmission contents are sent to the FAX transmission control device 105. In the fax transmission control device 105,
The recipe information corresponding to the content of the video signal at the transmission timing is read from the recipe database 104. This recipe information is sent from the FAX sending device 106 as facsimile information. The sent recipe information is faxed to a registered viewer via the PSTN 107.

As described above, according to the present embodiment, it is possible to combine the transient information of the sound and the image with the permanent information of the printed matter, so that the information during the radio broadcast time or the television broadcast time can be transmitted in real time. The information can be output to the viewer, the qualitative and quantitative effects of the information provision can be increased, and the recording needs of the viewer can be met in a timely manner.

In the above embodiment, the case of television broadcasting has been described, but the present invention can also be applied to the case of radio broadcasting. In this case, the same effect can be obtained.

In the above-described embodiment, the case where the information to be provided is recipe information in a cooking program is described. The present invention can also be applied to the case of local weather information in a local agricultural program.

In the above embodiment, the case where the period in which the fixed pattern signal as the transmission timing signal is multiplexed is a specific period in the character signal superimposable period in the vertical blanking period is described. The present invention
Any period may be used as a period for multiplexing the fixed pattern signal as long as the period does not hinder transmission and reproduction of the video signal.

[0024]

As described above, the information providing system of the present invention detects a fixed pattern signal from a video signal in which a fixed pattern signal is multiplexed, and sends a video signal to a specific subject at the timing when the fixed pattern is detected. Since facsimile data is transmitted, information during a radio broadcast time or a television broadcast time can be output to a viewer in real time.
