DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording reservation method suitable for use in a case where a broadcast program broadcast via a broadcasting satellite is reserved and recorded in a video cassette recorder.

[0002]

2. Description of the Related Art Conventionally, a video cassette recorder (hereinafter, referred to as a video cassette recorder)
When a broadcast program (program) is reserved and recorded (recorded) in a VCR, the following is performed. That is,
From a television program list described in a newspaper or the like, a broadcast channel of a desired broadcast program, a broadcast start time and a broadcast end time are confirmed, and a remote controller (hereinafter, referred to as a remote controller).
This is input to the VCR and transferred to the VCR body. Alternatively, the channel and time may be directly input to the VCR body.

In recent years, a G code (registered trademark) system, which replaces such a system for inputting time, is becoming widespread. In the G code method, a predetermined number (G code) is assigned to each broadcast program, and the user checks the G code (number) of the broadcast program for which reservation recording is desired from a television program list such as a newspaper. Then, this number is input from the remote controller to the VCR main unit corresponding to the G code, or directly to the main unit. The VCR body converts the G code into a broadcast channel, a broadcast start time, and a broadcast end time.

In addition, VCs that do not support the G code system
A dedicated device (adapter) for causing R to execute a reservation recording operation is also commercially available. When the G code is input, the device outputs a remote control signal to the video tape recorder to start a recording operation of a predetermined broadcast channel at a time corresponding to the G code, and the end time corresponding to the G code is reached. At this time, a remote control signal for terminating the recording operation is output.

[0005]

However, in any of the above-mentioned conventional methods, the user himself / herself who wants to make a recording reservation is required to specify a desired broadcast program from a TV program column such as a newspaper, a channel, a time or a number. Must be entered. That is, for example, when a conventional VCR is installed in a remote place where a remote control signal cannot reach,
When making a reservation for recording a CR, the user must move to the place where the VCR is installed or make a reservation for recording via a third party near the place where the VCR is installed. Practically, there is a problem that a recording reservation cannot be made at a place other than the place where the VCR is installed.

[0006] The present invention has been made in view of such a situation.
It is an object of the present invention to provide a system that can easily perform reservation recording.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A user accesses a recording reservation service company from a public network, multiplexes and transmits recording reservation data to an independent data section of a BS, and a VCR at home receives and decodes the data to record. One embodiment of the present invention for setting a reservation will be described below.

FIG. 1 shows a configuration of a recording reservation system for realizing the above-mentioned recording reservation. When attempting to make a recording reservation, the user first accesses a recording reservation service company using the telephone 1 using a general touch-tone line. As the telephone 1, a telephone provided in a private home or a company, a mobile telephone, a car telephone, a ship, a train, an airplane telephone, etc., which can be connected to a public telephone or a general push-phone line can be used. However, the telephones that can be used are limited to those using a touch-tone line. This is because when a user transmits information necessary for recording reservation to be described later to a recording reservation service company, a push-tone signal transmitted by a touch-tone telephone is used.

Using the touch phone line of the telephone 1,
When the user makes a call to the recording reservation service company via the public network 2, the public network interface 3 of the recording reservation service company responds. The public network interface 3 is a computer 4 of the user's recording reservation service company.
And a public network 2, which is provided in a recording reservation service company.

When the user accesses the computer 4, the computer 4 reads from the contractor database hard disk 5
Check whether the accessing user is a registered user. If not registered,
Refuse the recording reservation service. If the registration has been made, the data necessary for recording reservation is transmitted to the broadcasting center 6. The computer 4 and the contractor database hard disk 5 are also provided in the recording reservation service association.

In the broadcast center 6, the recording reservation data is transmitted to the BS.
(Broadcasting satellite) multiplexed in the independent data section to 7 and broadcast. The broadcast signal is received by the user's VCR 9 via the BS 7 and the outdoor device 8 installed at the user's home or the like, a recording reservation is set, and a video output is output to the television device 10 so that the user can Watch the recorded image.

Here, the data format of the contractor stored in the contractor database hard disk 5 will be described. As shown in FIG. 2, the hard disk 5 can write contractor data of a maximum of 2 to the 30th power (about 1 billion). This number is determined, for example, for the following reason.

Normally, theoretically, it is assumed that 10% of the highest manageable number is an actually manageable number.
100 million people who divide 100 million people by 10 is the number of subscribers who can actually manage. When considering services in Japan, Japan's population is about 120 million, so it will be sufficient for the time being. In order to record the data of 100 million subscribers, a large capacity of about 95 gigabytes is required, but it is not necessary to equip the hard disk of this capacity from the beginning, and What is necessary is just to add according to increase. Contractor data starts with personal information 1 (41),
Up to the 2 30th contractor data is arranged in a fixed length.

The data format of each contractor is represented by 761 bits from the valid bit 42 to the contract expiration date 49. The first one bit is assigned a valid bit 42, which indicates whether or not there is subscriber data. That is, the valid bit 42 is "
It means that it exists when it is 1 and does not exist when it is 0. The reason why such a bit exists is that when a certain user cancels the contract after the contract, the user uses the bit. This is because the part of the contractor data in the hard disk 5 that has been used may become empty.

Following the valid bit 42, the contractor ID 43
Is written over 30 bits. This is 2 of 30
This is to manage passengers. The following VCRID44 is
This is an ID previously assigned by the manufacturer for each VCR. This is used for specifying a VCR for which the contractor makes a recording reservation when the contractor makes a recording reservation (described later).
The password 45 following the VCRID 44 is the password of the contractor. This password is a four-digit number, and there can be 10,000 types from "0000" to "9999". To represent this password in binary, 14 bits are required. Then, one is added to the contractor's name 46.
6 bytes, 64 bytes for address 47, 30 for phone number 48
Bit (because telephone numbers are up to 10 digits in Japan,
30 bits are required in decimal notation).
Six bits are allocated. The contract expiration date 49 is 16 bits because the contract expiration date requires 7 bits (requiring 7 bits to represent 100 years), 4 bits for the month, and 5 bits for the day, for a total of 16 bits.

Next, the configuration of the public network interface 3 will be described. In the public network interface 3, as shown in FIG. 3, the CPU 71 receives access from the public network 2, controls the hook switch control circuit 67, closes the hook switch 64, and connects the line to the public network 2. The voice synthesizer 65 transmits a predetermined voice signal to the public network 2 via an interface 66 based on an instruction from the CPU 71. The decoder 62 includes a speech synthesizer 65
And decodes the push-tone signal according to the audio signal from the CPU 71 and transmits the signal to the CPU 71 via the interface 63. Then, the CPU 71 converts the decoded signal into RA
The information is stored in M70, communicates with the computer 4 via the interface 68, and performs processing based on instructions from the computer 4. The control program of the CPU 71 is stored in the ROM 69.

Here, the format of the recording reservation data broadcast from the broadcasting center 6 based on the touch-tone signal necessary for the recording reservation input by the telephone 1 from the user will be described. The recording reservation data is, as shown in FIG.
First, the VCRID 81 has 30 bits, and then the recording reservation date 82, recording start time 83, recording end time 84, and channel 85 are assigned 9 bits, 11 bits, 11 bits, and 4 bits, respectively. This VCRID8
1 specifies a VCR 9 for which a recording reservation is made.

Next, the configuration of the VCR 9 will be described. VC
In R9, as shown in FIG. 5, the BS tuner 101 receives the BS broadcast broadcast from the broadcast center 6 via the BS 7 and the outdoor device 8. B from BS tuner 101
The S broadcast signal is decoded into recording reservation data by the decoder 102 and transmitted to the CPU 103. CPU103
Stores the recording reservation data in the RAM 104,
From the VCRID 81 of the recording reservation data, it is determined whether or not the reservation target is the user based on the data stored in the ROM 105.

If the reservation target is the user, the recording reservation date / time 82, recording start time 83,
The recording end time 84 and the channel 85 are set in the recording reservation control circuit 106. Then, the timer circuit 107
At a predetermined time before the recording start time, the main power supply 109 is turned on via the power on / off control circuit 108, and the recording reservation control circuit 10
6, the recording / playback circuit 110 operates, and the BS tuner 1
01, or a video signal from a VHS tuner (not shown) is recorded.

When the recording end time comes after the start of the reservation recording, the recording reservation control circuit 106 controls the recording / reproduction circuit 110 to stop the reservation recording operation, and the main control via the power on / off control circuit 108. The power supply 109 is turned off. Then, the video output is sent to the television device 1
By outputting to 0, the user will appreciate the recorded image. The BS tuner control circuit 11
By controlling the BS tuner 101, the recording reservation data is transmitted to the CPU 103, and the BS signal is transmitted to the recording / reproducing circuit 110.

The operation of the recording reservation system configured as described above will be described. When the user makes a call to the recording reservation service company via the public network 2 using the touch-tone line of the telephone 1, the user responds to the public network interface 3 of the recording reservation service company. Then, the public network interface 3 performs processing based on the following FIG. 6 and FIG.

That is, as shown in FIGS. 6 and 7,
In step S1, an access (incoming call) from the public network 2 is waited, and if there is an access, the hook switch 64 is transmitted via the hook switch control circuit 67 in step S2.
Close and connect the line. Next, in step S3, the voice synthesizer 65 is made to say "This is a recording reservation service station" via the interface 66, and in step S4, "Please enter the contractor ID". The voice data is generated by reproducing voice previously recorded in the voice synthesizer 65.

In step S5, the system waits for the input of a push-tone signal of the contractor ID from the user. When the signal is input, in step S6, the CPU 71 sets the number corresponding to the push signal decoded by the decoder 62 to the interface 63. Read through and input numbers into RAM
70. As described above, the contractor ID is a 10-digit number notified to each user by the service company when registered in advance with the recording reservation service company. Based on this number, the service company needs to check whether the accessed user is a registered user. In step S7, the service company determines whether or not the ten-digit input has been completed. S5 to Step S7
The process up to is repeated. When the input of the ten digits is completed, the process proceeds to step S8, and in step S8, the speech synthesis device 65
Prompts the user to enter a password.

In step S9, the system waits for the input of the push-tone signal of the password from the user. When the password is input, in step S10, the CPU 71 assigns the number corresponding to the push signal decoded by the decoder 62 via the interface 63. Read and input the number into RA
It is stored in M70. As described above, the password is a four-digit number, and when the user registers with the service company, the user registers the desired number. This allows
The use of another party's contractor ID prevents unauthorized access to the service. Therefore, in step S11, it is determined whether or not the four-digit input has been completed, and the processes from step S9 to step S11 are repeated until the four-digit input is completed. When the four-digit input is completed, the process proceeds to step S12.

Subsequently, the recording month / day input processing in step S12, the recording start time input processing in step S13, and the recording end time / channel input processing in step S14,
The process is sequentially performed, and the process proceeds to step S15 in FIG. Step S1
The details of the recording date input process 2, recording start time input process in step S13, recording end time and channel input process in step S14 will be described later.

The recording month / day input processing in step S12, the recording start time input processing in step S13, and the step S12
When the input processing of the recording start time, the end time, and the channel desired to be recorded by the recording end time and the channel input processing of 14 is completed, the input data is transferred to the computer 4 in step S15 in FIG. Returns the processing result shown in Table 1 as a code after performing the processing described later.

[0034]

[Table 1]

This code is, as shown in Table 1, the following 4
There are types. Here, "0" means that the data input by the user has been processed without any problem and the service has been performed, and "1" means that the input contractor ID does not exist. ing. Also, “2” means that the password was incorrectly entered, and “3” means that the contract of the user has expired.

The public network interface 3 determines in step S16 whether or not a value has been returned from the computer 4, and in step S17, the returned value corresponds to the value shown in Table 1.
Is determined to be "0". If the code is "0", the voice synthesizing device 65 is made to say "recording reservation completed" in step S18, and the user is notified that the recording reservation service has been performed. The process proceeds to step S24, and if not "0", the process proceeds to step S19.

In step S19, it is determined whether or not the code from the computer 4 is "1". If the code is "1", in step S20, the voice synthesizing apparatus 65 informs the voice synthesizing apparatus 65 that "you are not a contractor, You can't receive it. "And proceed to step S24,
If it is not 1 ", the process proceeds to step S21.

In step S21, it is determined whether or not the code from the computer 4 is "2". If the code is "2", in step S22, "the password is incorrect, please"
Is returned to step S4, and the user is again instructed to input the contractor ID again.
If the code is not "2" in step S21, the process proceeds to step S23.

In step S23, since the code is "3", the voice synthesizing device 65 indicates that "the recording reservation service cannot be received because the contract has expired."
And the process proceeds to step S24. In step S24, the hook switch control circuit 67 is controlled to
The line with the public network 2 is cut off by the hook switch 64, and the process is terminated. If the user disconnects the line after connecting these lines until the public network interface 3 disconnects the line, even if any processing is currently in progress,
The process is interrupted, and the process returns to the call waiting state (step S1 (FIG. 6)).

Next, the recording date input processing in step S12 will be described. As shown in FIG. 8, first, in step S41, the voice synthesizer 65 is uttered "Please input the month to be recorded, and finally press #". In step S42, the process waits for a user input from the touch-tone button. Enter the month for which you want to make a recording reservation
Is pressed, and this "#" means that the input has been completed, and is always required. Because
Since the contractor ID and the password have a fixed number of digits, the public network interface 3 can know that the input has been completed when the predetermined number of digits has been input. Is a single digit from January to September and from October to 12
The month has two digits.

Therefore, in step S43, the input of "#" is confirmed. In step S44, while the "#" is not confirmed, the inputted number is stored in the RAM 70, and
Return to 42. When the input of "#" is confirmed, the step S
At 45, check if the entered month is between 1 and 12,
Otherwise, in step S46, the voice synthesizer 65 is made to say "Please input again", and the process returns to step S42 to prompt the user to input again.
If it is determined in step S45 that the input month is between 1 and 12, the process proceeds to step S47.

In step S47, as in the case of inputting a month, the voice synthesizer 65 is uttered "Please input the day to be recorded and finally press #". In step S48, the process waits for a user input from the touch-tone button. Then, similarly to the month input, in step S49, the input of "#" is confirmed. In step S50, the input number is stored in the RAM 70 unless "#" is confirmed, and the process returns to step S48. When the input of "#" is confirmed, step S51
Then, it is checked whether or not the input day exists in the month input before that. If not, the process proceeds to step S
At 52, the speech synthesizer 65 is uttered "Please enter again", and the process returns to step S48 to prompt the user to input again. In step S51, the input date is
If it exists in the month input before that, the recording month / day input process ends, and step S13 (FIG. 6) described next
To the recording start time input process.

The recording start time input process in step S13 is almost the same as the recording date input process in step S12. As shown in FIG. 9, first, in step S61, the voice synthesizing device 65 instructs the voice synthesizer 65 to start recording. The time you want to do, and press # at the end. " Step S62
Wait for user input from the touch-tone button. In step S63, input of "#" is confirmed, and in step S64
Then, as long as "#" is not confirmed, enter the entered number into RA
The result is stored in M70, and the process returns to step S62. When the input of "#" is confirmed, it is checked in step S65 whether the input time is between 0 and 23. If the input time is other than this, in step S66, the voice synthesizing device 65 is instructed to "again." Please enter. ", And step S62
And prompt the user for input again. In step S65,
If the input time is between 0 and 23, the process proceeds to step S67.

In step S67, similarly to the time input,
The voice synthesizing device 65 is uttered, "Enter the amount to start recording, and press # at the end." Step S6
At 8, wait for user input from the touch-tone button. Then, in step S69, the input of "#" is confirmed. In step 70, while the "#" is not confirmed, the inputted number is stored in the RAM 70, and the process returns to step S68. "
When the input of "#" is confirmed, it is checked in step S71 whether the input value is between 0 and 23. If not, the voice synthesizer 65 is sent to the voice synthesizer 65 in step S72.
"Please input again" is uttered, and the process returns to step S68 to prompt the user to input again. Step S7
If the input value is between 1 and 23, the recording start time input processing is terminated, and the process proceeds to the recording end time and channel input processing in step S14 (FIG. 6) described below.

The recording end time and channel input processing in step S14 are almost the same as the recording start time input processing in step S13. As shown in FIG. 10, first, in step S81, the voice recording apparatus 65 Enter the time to end and press # at the end. " In step S82, the process waits for a user input from the touch-tone button. In step S83, the input of "#" is confirmed. In step S84, the input number is stored in the RAM 70 unless "#" is confirmed, and the process returns to step S82. When the input of "#" is confirmed, step S85
Then, check whether the input time is between 0 and 23,
Otherwise, in step S86, the speech synthesizer 65 is uttered "Please input again", and the process returns to step S82 to prompt the user to input again.
If it is determined in step S85 that the input time is between 0 and 23, the process proceeds to step S87.

In step S87, similarly to the time input,
The voice synthesizing device 65 is uttered, "Enter the amount to end the recording, and press # at the end." Step S8
At 8, wait for user input from the touch-tone button. Then, in step S89, the input of "#" is confirmed. In step S90, the input number is stored in the RAM 70 while "#" is not confirmed, and the process returns to step S88. "
When the input of "#" is confirmed, it is checked in step S91 whether or not the input is between 0 and 59. If not, the voice synthesizer 65 is sent to the speech synthesizer 65 in step S92.
"Please input again" is uttered, and the process returns to step S88 to prompt the user to input again. Step S9
If the input is between 0 and 59 in step 1, the process proceeds to step S93.

In step S93, the speech synthesizer 65
Then, say "Enter the channel to record, and press # at the end." In step S94, the process waits for a user input from the touch-tone button. Then, in step S95, the input of "#" is confirmed, and in step S96, the input number is stored in RAM while "#" is not confirmed.
And the process returns to step S94. When the input of "#" is confirmed, it is checked in step S97 whether or not the input channel exists, and if not, in step S98, "Please input again" to the speech synthesizer 65. ", And returns to step S94 to prompt the user to input again. If it is determined in step S97 that the input channel is a channel that exists, the recording start time input process ends, and the process returns to step S15 (FIG. 7).

Next, the processing of the computer 4 in step S15 of FIG. 7 will be described with reference to FIG. The computer 4, as shown in FIG.
The system waits for data transfer from the public network interface 3 and, when transferred, searches for a contractor ID in the contractor database hard disk 5 in step S102 to find the same data as the transferred contractor ID. Subsequently, step S1
In step 03, it is determined whether or not the contractor ID is found in the contractor database hard disk 5, and if not found, in step S104, this user is not contracted.
It is determined that the ID has been entered incorrectly, the code "1" is returned to the public network interface 3, and the process is terminated.

If the contractor ID is found, in step S105, the contractor's password 45 is compared with the password input by the user to check whether they match. If they do not match, a code "2" is returned to the public network interface 3 in step S106, and the process is terminated. When the agreement of the password is confirmed, the contract expiration date is checked in step S107. If the contract has expired, the code 3 is returned to the public network interface 3 in step S108, and the process is terminated.

When these checks are passed, a recording reservation service is performed. First, in step S109, the VCR
The ID 44 is read. Next, in step S110, based on the data necessary for the recording reservation input by the user, FIG.
The recording reservation data in the format shown in (1) is created and transmitted to the broadcasting center 6 (FIG. 1). Then, based on the recording reservation data, the VCR 9 performs a recording reservation process described later. Broadcast center 6 for recording reservation data in step 110
When the transmission to is completed, in step S111, the code "
"0" is returned to the public network interface 3, and the process is terminated.

In the recording reservation processing of the recording reservation data of the VCR 9, the BS signal received by the BS tuner 101 is output to the decoder 102 in step S 121 as shown in FIG. The decoder 102 extracts the recording reservation data multiplexed in the independent data section from the signal. CPU
103 reads out the recording reservation data,
Write to 4.

Next, in step S122, the CPU 103
Reads its own ID, that is, VCRID, from the ROM 105, and checks in step S123 whether the ID matches the VCRID of the received recording reservation data. If they are different, the process ends without doing anything. If they match, in step S124, the recording reservation date 82, recording start time 83, recording end time 84, and channel 85 are read from the recording reservation data, and step S125 is performed.
The recording reservation date and time, recording start time 83, recording end time 84, and channel 85 are set by the recording reservation control circuit 1.
06, and set to end the processing.

As described above, according to the recording reservation system of this embodiment, when the user makes a call to the recording reservation service company via the public network 2 using the touch-tone line of the telephone 1, the recording reservation service If the public network interface 3 of the company responds and is connected to the computer 4 via the public network interface 3, the computer 4 searches for the contractor ID from the contractor database hard disk 5, and if the contractor ID is registered. Then, data necessary for recording reservation is transmitted to the broadcasting center 6. The broadcast center 6 multiplexes the recording reservation data into the independent data section of the BS,
The broadcast signal is received by the user's VCR 9 via the BS) 7 and the outdoor device 8 installed at the user's home or the like, so that the VCR 9 sets a recording reservation. By using the telephone 1 at an arbitrary time from an arbitrary place distant from the installed place of the installed VCR, it is possible to easily, easily and surely make a scheduled recording of a desired broadcast.

In the above embodiment, the recording means is a VCR.
However, the present invention is not limited to this, and may be an optical disk device that records an image on a phase change optical disk, a magneto-optical disk device that records an image on a magneto-optical disk, or a recording device that records audio signals such as music. It goes without saying that the present invention can be similarly applied to the reservation of a device (a device such as a DAT or an optical disk) for recording a digital signal (for example, digital information such as news from a communication satellite).

Further, the input means is not limited to a telephone, but a personal computer may be connected to a general line by a modem or the like, so that recording reservation data can be exchanged without using an audio signal. By doing so, the user creates a plurality of recording reservation data on the personal computer, and the actual reservation can be made in a short time without human intervention. The recording control is performed by connecting the computer 4 via a general line, and controlling the VCR.
Recording control may be performed by communicating with a personal computer installed near the CR.

Further, although the BS is used as the second communication means, the present invention is not limited to this, and the same effect can be obtained in a system using cable communication as the second communication means.
