DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A broadcast program data recording and distribution system according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of hardware of a broadcast program data recording and distribution system of the present invention. The main part of the broadcast program data recording and distribution system 1 is composed of a server 2 for recording program data of a broadcasting station and a terminal 3 owned by each user and connected to the server 2 via the Internet I. The server 2 includes a tuner unit 2b, a hard disk 2c, and a communication control unit 2d with the control unit 2a at the center. The tuner 2b is for receiving a broadcast signal from a broadcast station, and is connected to a receiving antenna 2e. The broadcast signal received by the tuner 2b includes, for example, a signal using a radio wave such as a terrestrial wave or a satellite wave. Further, the broadcast may be of an analog type or a digital type. Since the system 1 records program data in a digital format, when an analog signal is received, it is converted into a digital signal by an AD conversion circuit provided in the control unit 2a, and then the hard disk 2
Record in c. Further, a plurality of tuners 2b may be provided depending on the broadcasting mode. Therefore, even if the broadcasting format is changed in the future, if the service provider that records and distributes the program using the present system 1 responds by adding or changing the tuner unit, the user can change the broadcasting format. The user can enjoy the service of recording and distributing program data without bothering.

The control unit 2a has a function of controlling the entire server 2, and a main part is constituted by a CPU and a memory. The hard disk 2c stores a program for operating the CPU, and also stores each request transmitted from the terminal 3 and program data. The program data stored in the hard disk 2c is based on a digital signal as described above, and is, for example, a Motion-JEPG or an MPE.
Data compressed by a method such as G is used.

The communication control unit 2d is for connecting the server 2 to the Internet I.
A (Terminal Adapter) and DSU
(Digital Service Unit) is applied. This communication control unit 2d includes a first provider P1
Is connected to the Internet I. Thus, the request storage unit is realized by the control unit 2a and the hard disk 2c, the program data recording unit is realized by the control unit 2a, the tuner unit 2b, and the hard disk 2c, and the distribution unit is realized by the control unit 2a and the communication control unit 2d. Is realized.

The terminal 3 (terminal A, B or C) allows each user A, B or C to transmit a program data recording request or a viewing request to the server 2, distribute program data from the server 2, Is a terminal for receiving the notification. The various notifications here are, for example, a notification of whether or not a recording reservation can be made. The terminal 3 includes a hard disk 3c centering on the control unit 3a, a communication control unit 3d, a D / A conversion unit 3e,
And a display 3f. Control unit 3
“a” has a function of controlling the entire terminal 3, and a main part is configured by a CPU and a memory. The hard disk 3c is C
While storing the program for operating the PU,
The program data transmitted from the server 2 is stored. The communication control unit 3d connects the terminal 3 to the Internet I. For example, similarly to the communication control unit 2d of the server 2, a modem or a TA and a DSU are applied. This communication control unit 3d is connected to the Internet I via the second provider P2. The D / A converter 3e has a function of receiving a digital signal of the program data stored in the hard disk 3c from the controller 3a and converting the digital signal into an analog signal so that the display 3f can display the digital signal. The display 3f is a device for displaying a program using the analog signal converted by the D / A conversion unit 3e.

ply) and the like are applied.

The terminal B or the terminal C has the same configuration as the terminal A, and is connected to the Internet I via the second provider P2. Further, the terminal B or the terminal C may be configured to be connected to the Internet I via a provider different from the terminal A. A typical example of the terminal 3 is, for example, a personal computer. The personal computer 3 is connected to the server 2 via the Internet I, can transmit each of the requests, and can receive and reproduce distributed program data. The device is not limited to a personal computer as long as it has functions. The terminal is not limited to the case where the terminal is owned by the user, but may be lent for a fee or free of charge.

By using the present system 1, it is possible to provide a service of recording a program broadcasted from a broadcasting station on behalf of a user and distributing the program in response to a request of the user. For example, we manage for each user,
A service in which a recording reservation is received from each user within the range of "time allotted", which is a time during which recording reservation can be made in the server, and recording is performed for a fee or free of charge and distributed. In this case, "time allotted"
Initially uses the basic time set at the time of the contract,
As each user makes a recording reservation, the “required time”, which is the required time of the program reserved for recording, is reduced at any time.

Hereinafter, such a recording / distribution service using the present system will be described. 2, the server 2 stores a recording list 4 and program data 5 in a hard disk 2c. The recording list 4 is a list for managing the reservation status, recording progress status, and the like of each user, and is divided horizontally for each program title and vertically for each user. For example, when user A requests a recording reservation for the program title “Winter Day”,
The recording reservation is registered in the server 2 in the procedure shown in FIG.

In FIG. 3, first, a user name is obtained,
It is stored in "USER" (S1). Here, "A" corresponds to the user name, and more specifically, an ID code determined to identify each user at the time of contract for the recording / distribution service is acquired (the same applies to the following). . Next, the title of the program to be recorded is obtained, and "PR
OG "(S2). Here, “Winter Day” corresponds as the program name, and more specifically, a program code defined for specifying each program is acquired. Next, "US
The time allotted for ER (= A) is compared with the time required for PROG (= “winter day”) (S3). "USER
If the “time of (= A)” is less than the “time required for PROG (=“ winter day ”)” (NO in S3), “reservation failure” is notified to terminal A (S9), and the process ends. . on the other hand,
If the “TIME of USER (= A)” is equal to or more than “the required time of PROG (=“ Winter Day ”)” (YE in S3)
S), it is determined whether “PROG” (here, “winter day”) is already registered in the recording list (S).
4). Here, if "PROG" is not registered,
“PROG (=“ Winter Day ”)” is additionally registered in the recording list (S5), and if “PROG” is registered, “U
SER ”is registered in association with“ PROG ”(S
6). Thus, a “reservation” request is registered at the position where the program title is “Winter Day” and the user name is “A”.

Next, the "time required for PROG (=" winter day ")" is subtracted from "the time allotted for USER (= A)" (S7), and the "time allotted for user A" becomes "winter day". Time ". After that, the reservation success is notified to the terminal A (S8). It should be noted that in this notification, a notification of the reduced “time spent by the user A” may also be given.

In the above procedure, the reservation of the user "A" is registered on the recording list 4. The reservations of the users B and C are registered in the same procedure. Note that in S3, the “time of USER (= A)” is changed to “PROG”.
(= “Winter day” time) ”, an additional charge is collected separately, and the process proceeds to S4.
A recording reservation may be made. In the present system 1, when a plurality of users (for example, user B and user C in the figure) receive a recording reservation for the same program (program "Summer Day"), the program data is simply stored in the hard disk 2c. It is recorded at once and shared by a plurality of users B and C. By sharing the recorded program data among a plurality of users, the hard disk 2c
Can be reduced in the total amount of data to be recorded.

The recording list has a column for confirming the recording status of the program, which contributes to the smooth operation of the service. In this recording list, with respect to the program for which "recorded" is displayed, each user can make a viewing request and receive distribution of the program data. For example, when the user C requests viewing of the program title "Summer Day", the server 2 distributes the program data of "Summer Day" in the procedure shown in FIG.

In FIG. 4, first, a user name is obtained and stored in "USER" (S11). here,
“C” corresponds to the user name. Next, recording list 4
, A program list that can be viewed by the user C is notified (S12). In the case of FIG. 2, only “summer day” can be viewed. Next, the code number of the program selected by the user C from the program list notified in S12 is obtained (S12).
13). In the case of FIG. 2, the program code of "summer day" is selected and acquired. Next, a confirmation is made to the user C as to whether to cancel the viewing request (S14). If the user C cancels the viewing request, the process ends. If the user C does not cancel the viewing request, the server 2 distributes the program data (S15). In this way, the user C can receive the distribution of the recorded program “Summer Day”.
Although not shown in FIG. 2, the user A or B can similarly receive the recorded program distribution.

Each user transmits a separately defined additional request to the server 2 for a fee or free of charge.
For example, an additional service such as a commercial data (CM) deletion service can be received. in this case,
First, a user who desires a service transmits a CM deletion request to the server 2 before or before making a viewing request, while the control unit 2a of the server 2 receiving the CM deletion request.
After deleting commercial data from the program data recorded on the hard disk 2c, the communication control unit 2d may deliver the program data from which the commercial data has been deleted to the user. In the present system 1, since the program data is recorded in a digital format as described above, the commercial data can be easily deleted by specifying and storing the address where the commercial data is recorded at the time of recording. Can be. In this way, the user can view a program without commercial video, and can reduce the amount of data stored in the hard disk 3c of the terminal 3. When a commercial data deletion service is provided for a fee, a recording / distribution service provider may return a part of the fee for the service to a broadcasting station or a program sponsor.

In the recording and distribution service using the system 1, each user deletes an unnecessary reservation registration, thereby recovering the "time required" by the "required time" of the deleted program. You can also. For example, user B
Requests deletion of the program titles “Spring Day” and “Summer Day”, the server 2 performs deletion registration according to the procedure shown in FIG.

In FIG. 5, first, a user name is obtained and stored in "USER" (S21). Here, “B” corresponds to the user name. Next, a program list reserved for recording by the user B is notified from the recording list 4 (S22). In the case of FIG. 2, "spring day", "summer day",
“Autumn day” and “Winter day” are reserved for recording. Next, the code number of the program selected by the user B from the program list notified in S22 is obtained (S23). FIG.
In the case of, “spring day” or “summer day” is selected and acquired. Next, a confirmation is made to the user B as to whether to cancel the deletion request (S24). If the user B cancels the deletion request, the process ends as it is. If the user B does not cancel the viewing request, the reservation of the program ("spring day" or "summer day") is deleted from the recording list (S25). Next, it is checked whether a reservation of another user exists in the program (S26). If there is another user's reservation, the process ends as it is, otherwise, the program is deleted from the recording list (S27).

In this way, the user C makes an erasure registration for the recorded programs "Spring Day" and "Summer Day", and only for the "time required" of the program "Spring Day" or "Summer Day". User time can be recovered. Although not shown in FIG. 2, the user A or C can similarly delete the recorded program.

In the present system 1, if all users who have made a recording request for a certain program make an erasure request for that program (YES in S26), the hard disk 2c of the server 2 By deleting the program data recorded in the server 2, the program data in the hard disk 2c is sequentially reduced, and the total amount of data recorded in the server 2 is reduced. Usually, the program data to be recorded increases cumulatively, but the system 1 can be operated in this way without increasing the hard disk 2c of the server 2 more than necessary.

When erasing program data, if the program data to be erased is backed up in another area of the hard disk 2c and the backup file is stored for a certain period of time, If so, it is possible for the user to view again the program data for which the erasure was registered in the past.

As described above, in the present embodiment, recording of a program broadcasted from a broadcasting station is performed on behalf of a user,
It is possible to provide a service to be delivered in response to a user request. Further, in this embodiment, the tuner unit 2b for receiving the broadcast is owned or managed by the service provider, so that if the service provider introduces the tuner unit 2b corresponding to a plurality of broadcast modes, each user will have a corresponding broadcast. The service can be easily and inexpensively enjoyed without purchasing the tuner unit 2b corresponding to the mode.

In this embodiment, the server 2 and the terminal 3
Is connected via the Internet I, so that there is no need to provide a dedicated communication line. In addition, the user can transmit the above-mentioned requests and receive the program data by WW.
Since it can be performed using a W browser, it is possible to easily access the server 2 from whereabouts.

In this embodiment, since each user can make various addition requests such as deletion of commercial data, the convenience of the service can be improved. Further, since the recorded program data is stored in the server 2 managed by the service provider, it becomes difficult for a user or a third party to make illegal copies.
Therefore, the copyright of the broadcasting station or program creator is effectively protected.

The present invention can be variously modified without being limited to the configuration of the above-described embodiment. For example, the connection between the server and the terminal is not limited to the connection via the Internet. It may be a newly provided dedicated communication line.

A service for counting recording reservation requests or viewing requests transmitted by each user for each program title, creating a popularity ranking of each program based on the count value for each program title, and distributing the ranking to each user. It can be added. In this way, each user can know the degree of popularity of each program, and the convenience of the present system is further enhanced. In addition, a broadcast station or a program production company can use it as an example of an audience rating survey by receiving the notification of the popularity ranking.

Further, in the above embodiment, the user is identified by the ID code and the program is specified by the program code. However, the authentication of the user and the specification of the program are not limited to the method using such a code. This may be performed using the user's name or the program name itself.

[0040]

As described above, according to the first or fifth aspect of the present invention, each user does not need a home server for recording a broadcast program, and can use a less expensive terminal such as a personal computer. In this way, the user can economically receive and enjoy the recorded program.

According to the second, third, sixth or seventh aspect of the present invention, the total amount of data recorded on the server managed by the recording agent can be reduced.
The recording and distribution service provider can refrain from adding a storage device such as a hard disk in the server. That is, the recording and distribution service provider can reduce the operating cost of the recording and distribution service.

According to the invention of claim 4 or claim 8,
Each user can receive the distribution of the program data from which the commercial data has been deleted as necessary, so that the convenience of each user is improved.

According to the ninth aspect, each user can know the degree of popularity of each program, and the convenience of each user is further enhanced.

According to the tenth or eleventh aspect of the present invention, the above-described first to eleventh aspects can be realized.
