Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording reservation control system and a recording reservation control method applied to a VTR or the like.

[0002]

2. Description of the Related Art A VTR is provided with a program reservation function so that a program of a set channel can be automatically recorded at a set time. By using such a program reservation function, for example, a desired program can be recorded even while out, which is very convenient. Conventional VT
The R program reservation is for inputting the recording start time, recording end time, and recording channel by referring to the program guide published in newspapers, magazines, etc., which is a very difficult and time-consuming operation for the user. Met. Therefore, a program has been introduced which allows a program to be reserved by inputting a code (G code) assigned to each program. When such a code is used, the start time and end time of the program, the channel and the like can be easily set only by inputting the code published in newspapers and magazines, which is very convenient.

[0003]

However, the conventional VT
For R program reservation, refer to the program schedule published in newspapers and magazines, whether you make a program reservation by inputting the start time, end time, channel, etc. individually or by making a code reservation. Since the program is reserved in advance, there is a problem that it cannot be dealt with when the schedule of the broadcast program is changed.

[0004] For example, when a baseball game is broadcast, it is often the case that the game time is prolonged and the subsequent broadcast program is broadcast several minutes to several hours later than the scheduled time. Conventionally, when the broadcast time of a broadcast program is changed in this way, the program reservation must be canceled and a new program reservation must be set again.

Furthermore, in recent years, the number of channels has dramatically increased with the spread of CATV and satellite broadcasting. CAT
As the number of channels increases due to the spread of V and satellite broadcasting,
It is difficult to publish programs on all channels using newspapers and magazines. Among CATV channels, there are local broadcast channels and specialized channels that broadcast only to specific viewers. In the case of such local channels or specialized channels, it is difficult to provide program information in newspapers or magazines. In the case of satellite broadcasting, the service area is wide and the service area may cross the border. In the case of such a service area that crosses national borders, it is difficult for newspapers and magazines to provide program information to all viewers in the service area.

Therefore, an object of the present invention is to provide a recording reservation control system and a recording reservation control method which can more easily set program reservations and flexibly cope with program schedule changes.

Another object of the present invention is to provide a recording reservation control system and a recording reservation control method which can easily make a program reservation regardless of the increase in the number of broadcast channels and the expansion of service areas.

[0008]

In order to solve the above-mentioned problems, the invention of claim 1 uses the Internet to
Receiving means for receiving program information described in hypertext, display control means for displaying a program guide on a display based on the program information, and selecting means for selecting a desired portion on the program guide. And a means for requesting a server on the Internet to provide a code for use in setting a recording reservation when a predetermined section on the program guide is selected by the selecting means, and a code acquired from the server via the Internet. The recording reservation control system is characterized by having an output means for outputting a setting signal for setting the recording reservation to the recording means by using.

According to a fourth aspect of the present invention, program information described in hypertext is received via the Internet,
The program guide is displayed on the display based on the program information, and when a predetermined part on the program guide is selected, the server on the Internet is requested to provide a code for use in setting the recording reservation, and the Internet is displayed. The recording reservation control method is characterized in that the setting signal for setting the recording reservation is output to the recording means by using the code acquired from the server via the server.

[0010] WWW services on the Internet provide program information for television broadcasting and radio broadcasting. A command for setting the operation of the electronic device is embedded in the hypertext of WWW. If you click the part where this command is embedded, an infrared signal according to the operation of the command is transmitted, and the operation of each electronic device is set.

It is set to the code "142".

FIG. 8 shows the structure of the interface box 25. As shown in FIG. 8, the interface box 25 includes a code storage unit 52. As shown in FIG. 9, the code storage unit 52 stores code data (code and carrier wave information) of infrared signals for each device of each manufacturer. That is, the code and the carrier wave for controlling each device with an infrared signal are different for each manufacturer. Even within the same manufacturer, the code and carrier wave differ depending on the manufacturing date and model. As shown in FIG. 9, the code storage unit 52 stores all code data of each device of each company.

In FIG. 8, the personal computer 2
From 1 to the interface box 25, a command for setting the operation of the electronic device embedded in the WWW page is sent. This command is supplied to the controller 51 via the interface 53. The controller 51 interprets this command and reads the corresponding code data from the code storage unit 52. The output of the code storage unit 52 is supplied to the infrared signal generation unit 54, and the infrared signal generation unit 54 generates an infrared signal of a code and a carrier wave according to the code data.

As described above, the code and carrier wave for controlling each device are different for each manufacturer, and
Even with the same manufacturer, depending on the manufacturing date and model.
The code and carrier are different. On the other hand, the command sent to the interface box 25 is
Regardless of the manufacturer or model, it is common for each operation. Therefore, as described above, it is necessary to interpret the command and convert it into a code and a carrier wave corresponding to each device of each company. Therefore, the VTR 11, the FM tuner 12, and the MD player 1 that constitute the audiovisual system 5
3, registration of the television receiver 14 and the audio amplifier 15 is required.

The registration of this device is performed by the personal computer 21, for example. This registration may be set at the time when the audiovisual system is constructed, or may be registered and set each time the operation of each audiovisual device is set while viewing the WWW page. Further, this registration may be performed on the interface box 25 side.

As shown in FIG. 10A, in device registration, a model setting menu is first displayed. In the setting menu of this device, the corresponding device is selected from the VTR, the television receiver and the like. When you select the corresponding device,
As shown in 0B, the manufacturer's setting menu appears. When the manufacturer is set in the setting menu of this manufacturer,
As shown in C, the input screen for the manufacturing date appears. Here, when the manufacturing date is input, the manufacturer information and the manufacturing date information about the device are input. in this way,
When the manufacturer information and the manufacturing date information of the device are input, these information are sent to the interface box 25, and the manufacturer information and the manufacturing date information of each device are registered in the interface box 25. It

FIG. 11 is a flow chart showing the operation at this time. As shown in FIG. 11, when registering a device, first, a model setting menu is displayed (step ST11). It is determined whether or not a device such as a VTR, a television receiver, an MD player, etc. is selected in the setting menu of this device (step ST12). When the device is selected, a maker setting menu is displayed next (step ST13). In this manufacturer setting menu, A
It is determined whether a maker such as company B, company B, or company C has been selected (step ST14). Once the manufacturer is selected,
Next, the manufacturing date input screen is displayed (step ST
15). It is determined whether or not the manufacturing date has been input on the manufacturing date input screen (step ST16). When the manufacturing date is entered,
Information on the manufacturer and the date of manufacture is registered in the interface box 25 (step ST17).

For example, it is assumed that the manufacturer of the VTR 11 constituting the audiovisual system 5 in FIG. 1 is Company A, and the manufacturing date is between 1985 and 1990. And personal computer 2
It is assumed that the WWW screen as shown in FIG. 2 is displayed on the display 22 of No. 1 and the display 32A is clicked.
In this case, the command corresponding to the G code "142" is sent from the personal computer 21 to the interface box 25.

In the VTR manufactured by Company A and manufactured on the dates 1985 to 1990, as shown in FIG. 9, the code data corresponding to the G code "142" has the address "A".
7, A10, A8 ”. Therefore, of the code data stored in the code storage unit 52 in FIG.
The code data stored in "0, A8" is read.

This code data is used by the infrared signal generator 54.
Sent to. Then, the infrared signal from the infrared signal generator 54 is transmitted to the VTR 11. This allows
The G code “142” is set in the VTR 11.

FIG. 12 is a flow chart showing the operation of the interface box 25 at this time. 12
As shown in, it is determined whether or not a command has been sent from the personal computer 21 (step ST
21). When the command is sent, the command is interpreted (step ST22). Then, the data of the maker and the manufacturing date of the device registered in advance are called (step ST23). Code data corresponding to the operation of the command is determined based on the manufacturer information and the manufacturing date information of the device (step ST24).
This code data is read from the code storage unit 52 (step ST25) and transmitted as an infrared signal from the infrared generation unit 54 (step ST26).

In the above example, the interface box 25 converts the command for setting the operation of the electronic device into an infrared code corresponding to the command, but this conversion is performed on the personal computer 21 side. You may do it.

Further, in the above example, the manufacturer and the manufacturing date of each device are registered in advance. However, if the code corresponding to each command is read out for all models, each device is registered in advance. It is no longer necessary to register the manufacturer and the manufacturing date.

That is, as shown in FIG. 13, it is judged whether or not a command is sent from the personal computer 21 (step ST31), and if the command is sent, the command is interpreted (step ST3).
2). Then, the code data for performing the operation of the code corresponding to the command is sequentially read out for all models of all manufacturers (step ST33), and is sequentially transmitted as an infrared signal from the infrared generation unit 54 (step ST34).
In this way, if the code data of the corresponding operation is read out for all models of all manufacturers, one of them matches the device that constitutes the audiovisual system 5, so that the operation of that device Can be set.

Since the infrared signals have different code systems and carrier waves for each maker, even if the corresponding codes are sequentially read for all models of all manufacturers, there is a risk that the equipment malfunctions. There is almost no sex.

In the above example, the code storage unit 52 stores all the code data of each model of each maker in advance, but if the codes of all the models of all electronic devices are stored. , The number of codes is huge. Also, the code of the infrared signal may be changed.

Therefore, the code storage unit 52 is made readable / writable, and like the learning remote controller, the code storage unit 52 is made.
In addition, the code data may be taken in by an external input.

Also, this code data may be transferred using the WWW of the Internet. For example,
As shown in FIG. 14, in the program introduction WWW page,
An indication 36 is provided regarding the manufacturer and date of manufacture of the VTR. In this display 36, a command for fetching code data for each model of each maker is embedded. From this display 36, the VTR of the desired manufacturer and date of manufacture
When is selected, code data corresponding to the model is downloaded via the Internet 6.

FIG. 15 is a flow chart showing the operation at this time. As shown in FIG. 15, it is determined whether or not the display for setting the code data has been clicked (step ST41). When the display for setting the code data is clicked, a request for fetching the code data is output via the Internet 6 (step ST42). Then, it is determined whether the code data can be received (step ST43), and if the code data can be received, the code data is downloaded (step ST44).

At this time, the server for providing the code data may be placed in each broadcasting station in FIG. 1, or the server different from this may be placed in the server, for example, the server of the device manufacturer. You may do it. That is, when the code data is placed on the server of the manufacturer of the device and the desired manufacturer and the VTR of the manufacturing date are selected on the display 36, the FTP (File Transer Pro) of the manufacturer is selected.
tocol) server. And this FTP
From the server, the code data of the electronic device of the manufacturer is downloaded.

In the example of FIG. 1, the VTR 11, FM tuner 12, MD player 13, television receiver 1
4, the audiovisual system 5 such as the audio amplifier 15 is remotely controlled using infrared rays by the interface box 25. However, as shown in FIG. 16, a wired interface box 28 may be used. . In this case, the personal computer 21 and the
The VTR 11, the FM tuner 12, the MD player 13, the television receiver 14, and the audiovisual system 5 such as the audio amplifier 15 can be bidirectionally connected.

As described above, in the system to which the present invention is applied, the programs of the broadcasting stations 1, 2, and 3 are transmitted using the WWW service on the Internet. The schedule of the broadcast program by the WWW is immediately revised, for example, when the broadcast schedule is changed due to the extension of the baseball broadcast, and the latest information is always obtained. And, as described above, the program reservation can be easily performed by clicking the corresponding display.

Further, due to the spread of satellite broadcasting and CATV,
Although the number of television broadcasting channels is increasing, the Internet is an international computer network, so if you use the Internet, you can schedule programs for individual channels even if the number of channels increases or service areas cross national borders. Can be notified to the viewer.

The use of such a system is not limited to program reservation and the like. As described above, since the command for setting the operation of the electronic device can be easily created by using the hypertext, this system can be widely applied.

FIG. 17 shows an application example of such a system. In FIG. 17, 101 is a television receiver,
Reference numeral 102 is an illumination, and 103 is an air conditioner.
The television receiver 101, the illumination 102, and the air conditioner 103 include light receiving portions 101A, 102A, and 10A.
3A are provided respectively. These television receiver 101, lighting 102, air conditioner 103
The operation is set by an infrared signal from the interface box 104. The interface box 104 is connected to the personal computer 105.

In such a system, for example, it is assumed that the cooling strength of the air conditioner 103 and the brightness of the illumination 102 are always desired to be set optimally. In this case, using the personal computer 105, the optimum cooling intensity setting value of the air conditioner 103 and the optimum brightness setting value of the illumination 102 are described as commands in the hypertext.

In this way, the command in the hypertext from the personal computer 105 is sent to the interface box 104, and the interface box 104 outputs an infrared signal according to the command in the hypertext. With this, lighting 1
