2. Description of the Related Art In recent years, using text multiplex broadcasting, program table information comprising information representing the contents of individual programs scheduled to be broadcast (hereinafter, referred to as "program information") is stored in a vertical flyback period. A superimposed broadcast service is planned. By using this service, the program guide information superimposed on the broadcast wave is decoded on the receiving side, so that the broadcast station, broadcast date, broadcast start time, broadcast end time, genre of the broadcast program, etc. Program information can be known. Therefore, the program information is stored in advance, and based on the stored program information, the user sets the recording device to record in accordance with the start of broadcasting of a desired program (hereinafter, referred to as “recording reservation”). By doing so, a desired program can be automatically recorded (hereinafter, referred to as “reserved recording”).

[0003]

In the program information, broadcast time information indicating a broadcast time of a program is represented by a broadcast start time and a broadcast end time. When the recording reservation is set using the broadcast time information, the program that started broadcasting before the broadcast start time of the program reserved for recording (hereinafter referred to as `` recording reserved program '') also Regardless, it may be extended and broadcast. Such a situation often occurs, for example, in a sports broadcast program. In this manner, a program that has started broadcasting before a program reserved for recording (hereinafter, referred to as a “previous broadcast program”) is broadcast with its broadcast time extended beyond its end time, The broadcast start of the scheduled recording program is delayed by the extended broadcast time. That is, the broadcast time zone of the recording reservation broadcast is shifted by the extension time of the preceding program with respect to the recording reservation program. However, in the above-described recording apparatus, the scheduled recording start time and the scheduled end time of the scheduled recording program are not updated according to the extension of the preceding program. As a result, when the preceding program is extended, such as an extension of a sports broadcast, a problem arises in that the recording reservation program is not recorded for the extended time. According to the present invention, when there is a possibility that a program broadcast prior to a recording reservation program may be extended beyond the original broadcast end time, the user can determine the recording reservation program according to the user's judgment. An object of the present invention is to provide a reservation recording control device that can extend the recording end time by a predetermined time and make a recording reservation.

The recording device 52 is a recording / reproducing device such as a video tape recorder, and records a broadcast program. As mentioned above,
When the user inputs a program to be reserved for recording using the operation input unit 56, the reservation recording control device TRC1 enumerates programs that are likely to affect the end time (broadcast time) of the program reserved for recording. And the user
The recording end time is set to be delayed by a desired time.

The operation of the above-mentioned reservation recording control device TRC1 will be described with reference to the flowchart shown in FIG. First, in Step S2, the broadcast schedule program table generator 100 creates program table information Ipt representing the contents of a program scheduled to be broadcast based on the program information It stored in the broadcast schedule program memory 51. This program guide information I
Based on pt, the display 55 displays the program guide Pt scheduled to be broadcast as an image.

In step S4, the user determines a program to be reserved for recording with reference to the program guide Pt displayed on the display 55 in step S2. Then, the user operates the operation input unit 56 to generate a recording reservation instruction signal Sc indicating the determined content of the recording reservation, and outputs it to the reservation recording control device TRC1. The recording reservation program table generator 200 of the reservation recording control device TRC1 sets reservation recording based on the input recording reservation instruction signal Sc and generates recording reservation program table information Ipts. That is, the recording reservation program table generator 200 outputs the program table information I input from the broadcast schedule program table generator 100 based on the recording reservation instruction signal Sc.
From pt, broadcast station information Ibs (broadcast station code Ca), broadcast date information Ibd (broadcast start year code Cb, broadcast start month code Cc, broadcast start date code C of the program to be reserved for recording)
d), broadcast start time information Ibb (broadcast start time code C
e, broadcast start minute code Cf, broadcast start second code Cg),
The broadcast end time information Ibe (broadcast end time code Ch, broadcast end minute code Ci, broadcast end second code Cj) is extracted.

In step S6, the recording reservation program table generator 200 uses the detector 54 to broadcast on the same broadcasting station, that is, the same channel as the reservation recording program, and to broadcast before the broadcasting time of this reservation recording program. The presence or absence of a program of a specific genre is detected. That is, the same broadcasting station information Ibs as the recording reservation broadcasting station Sbs of the program reserved for recording,
Broadcast start time information Ibb before the reservation recording start time Srst and a genre code Ck representing the contents of a predetermined program
In order to detect the program having N as the interference candidate program Sdp, the detector 54 searches the program information It stored in the broadcast-scheduled program memory 51. As the code CkN representing a program of a specific genre, for example, a subcode Ck3 indicating a sport is set.

In step S8, as a result of the search in step S6, if the interference candidate program Sdp is not detected, that is, a program having the corresponding broadcast station information Ibs, broadcast start time information Ibb, and program genre code CkN is detected. If not, it is determined as No. Then, the process proceeds to step S38. In step S38, the broadcast end time information Ibe is set to the reservation recording end time S
Set to ret and end the process.

On the other hand, if the interference candidate program Sdp is detected in step S8, that is, sports (Ck3)
The recording start time S of the program reserved for recording without ending at the end time specified in the broadcast end time information Ibe as shown in FIG.
If there is a program whose broadcast may be extended beyond rst, YES is determined and the process proceeds to step S10.

In step S10, the detector 54
A disturbance candidate program table Sdpt representing the contents of all the found disturbance programs Sdp is generated. Then, the recording reservation program table generator 200 generates a reservation-disturbance program table TDp based on the disturbance candidate program table Sdpt and the program table information Ipt.
Further, the display 55 displays the reservation-jamming program table TDp.

In step S12, the user looks at the reservation-jamming program table TDp displayed on the display unit 55 and determines whether or not the reservation recording end time Sret of the reservation recording program is to be advanced. If the reservation recording end time Sret is not advanced, the process ends after proceeding to step S38 described above. On the other hand, if the reservation recording end time Sret is to be advanced, the process proceeds to step S14.

In step S14, the recording reservation program guide generator 200 displays a predetermined reference extension time Tpp in the reservation-disturbance program guide TDp corresponding to each detected interference candidate program Sdp. Then, the process proceeds to the next step S16.

In step S16, the user determines whether or not the reference extension time Tpp is appropriate as the extension time Tp for extending the reservation recording end time Sret of the recording reservation program Srp. If it is determined that the reference extension time Tpp is appropriate, the process proceeds to step S20.

In step S20, the initial value of the extension time is set to the extension time Tp. Then, the process proceeds to step S
Proceed to 36.

On the other hand, in step S16, the reference extension time Tp
If it is determined that p is not appropriate, the process proceeds to step S18. In step S18, the user operates the operation input device 56.
Is used to input the extension time Tp. Then, the process proceeds to step S36.

In step S36, the reservation recording end time Sret is rewritten to a time extended by the extension time Tp, and the recording reservation program table information Ipts is regenerated and recorded in the recording reservation program memory 210.

Steps S8 and S12
If it is determined No, in step S38, the broadcast end time Ibe of the recording reservation program Srp is set to the reservation recording end time Sret, and the recording reservation program table information I
pts is regenerated and recorded in the recording reservation program memory 210.

As described above, according to the reservation recording control device TRC1 of the present invention, a program of a specific genre which is scheduled to be broadcast before the program to be recorded is a program of the same broadcasting station (channel) as the program to be recorded. If there is a program reservation / recording interfering program, the fact is presented to the user as a reservation / recording interfering program table, and the user is inquired about the necessity of setting delay of the recording end time of the program to be reserved for recording. Then, the user can determine the change of the recording end time in consideration of the presented schedule recording interfering program table, and can execute the schedule recording so that the user can use it easily.

(Second Embodiment) A reservation recording control device according to a second embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 5, the reservation recording control device TRC2 according to the present embodiment includes a recording reservation program between the recording reservation program table generator 200 and the recording reservation program memory 210 of the reservation recording control device TRC1 shown in FIG. The management unit 202 has a configuration added. Note that the added recording reservation program manager 202 and recording reservation program table generator 200
These constitute the first recording reservation manager 200A.

The recording reservation program manager 202 updates the program at the step S18 or S20 described with reference to FIG. 4 when extending the reservation recording end time Sret of the program to be recorded by the user by the desired extension time Tp. With the set reservation recording end time Sret, the recording reservation program table information Ipts
To find a subsequent recording reservation program Srp which may be affected by the reservation recording time due to this recording extension as a recording reservation damage candidate program Svp. In this case, the reserved recording station Sbs is not a search condition. For the sake of simplicity, the recording reservation damage candidate program Svp is hereinafter abbreviated as the damage candidate program Svp. Also, the reservation recording end time Sre
If t is extended, the recording reservation program Srp that may function as the obstruction candidate program Sdp with respect to the subsequent damage candidate program Svp is referred to as an offense candidate program Apc.

The recording reservation program manager 202 further includes a damage candidate program table Sv representing all the detected damage candidate programs Svp.
pt is generated and output to the display 55. The user looks at the damage candidate set table Svpt displayed on the display 55 and determines whether or not to extend the reservation recording end time Sret of the program to be recorded. Then, when extending the user along with the determination result, the user uses the operation input device 56 to input the extension time Tp as the recording reservation instruction signal Sc to the recording reservation program table generator 200 (reservation recording control device TRC2).

When only one program is reserved for recording, as in the first embodiment described above, in order to avoid the influence of the preceding interference candidate program Sdp, the recording reservation program Srp
It is effective to extend the reservation recording end time Sret by a predetermined extension time Tp. However, when a plurality of programs are reserved for recording, if one reserved recording end time Sret of the reserved recording program Srp is extended, the broadcast start time information Ibb of the subsequent reserved recording program Srp may be cut off. In particular, when the broadcast sources of the two recording reservation programs Srp are different, the subsequent recording reservation program Sr
