Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a reservation system for automatically receiving or recording a radio or television broadcast program, an automatic broadcast program receiving apparatus, and an automatic broadcast program recording apparatus.

[0002]

2. Description of the Related Art At present, an automatic recording reservation system using a gem star code (so-called G code) as a reservation code has been adopted in order to automatically video record a television program desired to be recorded. This G code system is
A specific organization assigns a different numeric string of, for example, 4 to 8 digits for each television program, and uses this as a program identification code.

[0003] However, this G code system is:
Since the recording start time is set by the G code, it is necessary that the receiving device has a timer function. In addition, for example, when a broadcast time of a sports program is temporarily extended, the receiving device may have a timer function. If the actual broadcast start time is changed from the scheduled time, the desired reservation target program cannot be recorded as scheduled,
There is a problem. In addition, when using the G code system, the G code relating to the program to be reserved cannot be known without actually relying on a program table (that is, a G code list) such as a newspaper in which the G code is published. .
In addition, even if the G code number sequence is the same program that is broadcast regularly in the same time slot every week, a different number sequence is allocated and the number of digits of the number sequence is unified. Not very inconvenient.

As described above, the G-code recording reservation system currently used is uncertain because it does not specifically specify the program to be recorded, and is very complicated for the user. Operation is forced. Under such circumstances, there is a demand for an automatic broadcast program reception reservation system which can make a reservation for receiving a desired reservation target program by a simple operation and can reliably receive or record the reserved program. Have been.

Generally, in order to specify a TV program,
Since it is certain to use the name of the program, it is conceivable that the scheduled broadcast date and the program name are coded as a set and used for reservation of automatic reception of the program. However,
In such a system, the user needs to memorize the program name accurately, but in many cases, the program name is long and it is difficult to memorize it accurately. May not always be accurate and may be described in abbreviated form, for example. Therefore, it is not always possible to completely specify the program, the program name must be entered as textual information, and the reservation operation is complicated. There is a problem that it becomes.

[0006]

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail. FIG. 1 is an explanatory diagram of the transmitting side in the automatic broadcast program receiving reservation system of the present invention, and FIG. 2 is an explanatory diagram of the receiving side in the same system. On the transmitting side of the system, in a coding step 10, a program specific code is assigned to each program. This coding is performed in accordance with the following procedure, for example, at a program production company that produces television programs or at a broadcasting station that broadcasts or broadcasts television programs.

[0010] The program identification code is constituted by numbers representing the broadcast date and time when the television program is broadcast. Specifically, the program identification code is
The number on the calendar representing the broadcast date of the TV program is 2
A date code represented by a digit number and a time code represented by a four-digit number representing a standard time representing a broadcast start time of the television program by a four-digit number are combined in this order to form a total of six-digit number strings. You.

When the number on the calendar of the broadcast date is a single digit, the date code has a zero (0) prefixed to the number.
If the number on the calendar is two digits, it is constituted by the two-digit number. For example, the date code of the first day in each month is “01”, the date code of the second day is “02”, and the date code of the 31st is “31”.

The time code is composed of a two-digit number representing "hour" in a 24-hour clock and a two-digit number representing "minute" among hours and minutes representing the start time of the broadcast program. (In the case of one digit, "0" is prefixed to form a two-digit number.) These numbers are composed of a total of four digits joined in the order of hour and minute. Therefore,
For example, when the broadcast start time is 7:15 am, the time code is “0715”, and when the broadcast start time is 11: 5 pm, the time code is “2305”. The program identification code is composed of a six-digit number obtained by combining the two-digit number of the date code and the four-digit number of the time code in this order.

The above program specifying code is transmitted from a transmitting station as a control signal (hereinafter, referred to as a "program specifying signal") from a broadcasting station on the transmitting side prior to the start of broadcasting of the program. (Transmission step 12).

On the receiving side, as shown in FIG. 2, a receiving device 20 is provided, and a recording device 22 is connected to the receiving device 20, and a program reservation device 30 is connected to the receiving device 20. In the program reservation device 30, a decoder 32 connected to the reception device 20 is provided.
A storage unit 34 is provided, to which an input unit 36 is connected. Further, a comparison circuit 38 is provided, to which the decoder 32 and the storage unit 34 are connected together.
8 is a program receiving unit 21 of the receiving device 20 and the recording device 2
2 is connected.

In the program reservation device 30, the decoder 3
Numeral 2 is for decoding a program specifying signal based on broadcast radio waves received by the receiving device 20, transmitting a program specifying code based on a numeric string, and supplying the same to the comparison circuit 38. The input unit 36 is constituted by, for example, a numeric input device having a numeric keypad, and the program reservation code input by the input unit 36 is stored in the storage unit 34. This storage unit 34
It is assumed that a plurality of program reservation codes can be stored.

Here, the program reservation code comprises a date code of a number representing a broadcast date and a time code representing a broadcast start time, for example, 6 determined by the same procedure as in the case of the program identification code described above. It consists of a digit string.

The comparing circuit 38 stores the program specifying code obtained from the program specifying signal by the decoder 32 and the storage unit 34.
Compares the program reservation code stored in, and sends a code match signal when the contents of both numeric strings match,
This is supplied to the recording device 22.

When a code matching signal is supplied to the receiving apparatus 20 when the program receiving section 21 is not operating, a control circuit (not shown) for turning on the program receiving section 21 to activate the program receiving section 21 is provided. Is provided. Further, the recording device 22 is provided with a control circuit (not shown) for starting a recording operation for recording the content of the program received by the program receiving unit 21 when the code matching signal is supplied.
Reference numeral 40 denotes a display unit which can display a program reservation code stored in the storage unit 34, for example.

In the program reservation device 30 configured as described above, the program reservation code of the program to be reserved is input to the input section 36. For example, to reserve recording of a television program that starts broadcasting at 11:45 am on the 25th of the month, the date code “25” of the broadcast date is input in the input unit 36.
And the time code “1145” of the broadcast start time are combined in this order to form a six-digit program reservation code “25114”.
5 ". The numeric string of the program reservation code is stored in the storage unit 34.

After the program reservation code is input, the program to be reserved is actually broadcast at 11:45 am on the 25th, which is the start of broadcasting of the program to be reserved. Prior to this, the digit string "251145"
Is transmitted as a program specifying signal.

On the other hand, in the receiving device 20, the program specifying signal is received and supplied to the decoder 32, and the digit string “251145” of the program specifying code is added from the decoder 32 to the comparing circuit 38. The comparison circuit 38 determines whether the program reservation code stored in the storage unit 34 includes a program reservation code having the same numeric string as the program identification code, and determines whether the same program reservation code exists. If there is, a code match signal is transmitted, and this code match signal is supplied to the program receiving unit 21 of the receiving device 20 and the recording device 22.

In the receiving apparatus 20, the program receiving section 21 receives a program broadcast by receiving the code matching signal. Further, in the recording device 22, upon receiving the code match signal, the control circuit operates to start the recording operation, and the recording of the content of the broadcast program received by the program receiving unit 21, that is, the recording is performed. Will be As described above, the receiving side can automatically receive or further reserve the recording of the reservation target program, and can automatically receive and record the reservation target program accordingly. That is, the above code match signal can be used as a simple program reception start signal, or can be further used as a program recording start command signal.

The configuration of the program reservation device 30 shown is an example, and the specific configuration can be variously changed. For example, the input unit 36 may be separated from other components to be a so-called remote type, or the display unit 42 may be omitted and its function may be provided in the receiving device 20 or the recording device 22. Is also possible.

The time code is preferably represented by a 24-hour clock as described above, but may be represented by a 12-hour clock. However, in this case, at least 1
Since it is necessary for the digit number to be added to the four-digit number representing the hour and minute, it is composed of at least five digits. For example, when “0” and “1” are used to distinguish between morning and afternoon, when the broadcast start time is 7:15 am, the time code is “00715”,
The time code at 11:05 pm is “1110
5 ".

According to the automatic broadcast program reception reservation system as described above, any broadcast program is represented by a number sequence in which numbers representing the broadcast date and the broadcast start time of the program are listed. Since the program is identified by the code, the program identification code and program reservation using the same numeric string for one program are not required on both the transmitting side and the receiving side without the need for mutual confirmation. The code can be determined very easily. this is,
Using the elements that are unique to the program, such as the broadcast date and the broadcast start time of the program, and that are easy to distinguish from other programs and that are easy to distinguish, the codes are simply listed as the codes This is because it has been adopted.

According to the present invention, the following effects are specifically obtained. (1) Invariance of program specification The program specification code and the program reservation code of a certain broadcast program are automatically and uniquely determined at the stage when the scheduled broadcast date and time are determined. Even when the program is changed, the program is transmitted as the program specifying signal without changing the program specifying code on the transmission side, so that the receiver who makes the program a reservation target program can receive or record the program reliably. can do. This is because the program specifying code and the program reservation code specify the program itself, and do not simply specify the recording start time.

(2) Certainty of Specifying a Program At the same broadcast station or broadcast frequency, a plurality of broadcast programs are not transmitted repeatedly in the same time zone, so that a plurality of programs are included in one broadcast program. There is no overlapping of the specific codes, and therefore, the broadcast program can be reliably specified by one program specifying code or program reservation code. (3) Ease of Program Identification In order to input a program reservation code, it is necessary to know the scheduled broadcast date and start time from a broadcast schedule, etc., but this is sufficient, and therefore it is easy and reliable. The user can make a reservation for reception or recording of the program to be reserved.

(4) Possibility of guessing the program specifying code For a program such as a regular program or an event, an event or a sports tournament whose actual start time is known, the program can be referred to without referring to a broadcast schedule. It is easy to assume a reservation code, and the accuracy of the determined program reservation code is considerably high. (5) Since the program reservation code is composed of a simple numeral string, the input operation is extremely simple and can be used by any number of people, and there is little possibility that an operation error occurs.

In addition to the above, in the broadcasting station on the transmitting side, the program identification codes for all programs are determined automatically or unambiguously, so that by using this program identification code, all programs can be unified. This makes it possible to extremely easily perform a dynamic management, and has the effect of reducing broadcast accidents.

Although the present invention has been described with reference to specific examples, it is common that there are a plurality of broadcast waves that can be received at a certain receiving location. It is necessary to select or designate a broadcast station or channel for broadcasting the program to be reserved or a frequency to be broadcast. To achieve this, it is possible to provide a program reservation device for each channel and use a method of selecting a desired program reservation device. Specifically, for example, a channel code can be selected by setting a frequency code of one or more digits representing a channel, for example, a two-digit number at a receiver. It is also possible to use a device having a channel designation function completely different from the program specifying code or the program reservation code. Also,
By providing a recording time setting mechanism connected to the receiving device 20, the recording device 22, or the program reservation device 30,
The program may be recorded for a desired time.

In the above program specifying code and program reservation code, the month to which the broadcast date belongs and the number representing the year to which the month belongs are actually unnecessary. This is because the time when the scheduled broadcast date and time of all programs is actually determined is about one month before the scheduled broadcast date, and before that, the scheduled broadcast date and time of the program may fluctuate. is there. That is, in practice, the need to schedule recording of a program after a period of more than one month is small.

In the present invention, various changes can be made. For example, the receiving device 20, the recording device 22,
The program reservation device 30 and the program reservation device 30 can be connected to each other as independent devices. However, the configuration in which the program reservation device is incorporated into one of the reception device and the recording device, and the reception device, the recording device, and the program reservation device are different from each other. It is also possible to adopt a configuration in which they are combined as an integrated device. In the above description, a television broadcast is described as an example. However, the automatic broadcast program reception reservation system and apparatus of the present invention can be applied to reception and recording (recording) of a program by radio broadcast.

[0033]

As described above, according to the present invention, automatic reception of a desired program or reservation of reception / recording can be performed by extremely simple operation, and the program to be reserved can be reliably received. Alternatively, it is possible to provide a broadcast program automatic reception reservation system capable of achieving reception and recording. Further, according to the present invention, it is possible to provide a broadcast program automatic reception reservation device using the above-mentioned broadcast program automatic reception reservation system, and further provide a broadcast program automatic recording device having the broadcast program automatic reception reservation device. be able to.
