DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In a conventional recording device such as R, all programs that match the registered preference information are targeted, and even programs that have already been viewed in the past are recorded as long as they match the registered preference information. Therefore, there is a problem that useless recording is performed.

In the case of a rebroadcast program, a program that matches the registered preference information will be recorded, but if the rebroadcast program is simply not recorded, it will be recorded in the packet header or the like. When the receiving side detects this rebroadcasting identification code (or flag) by inserting the identification code (or flag) of the above, the recording device that prohibits the recording of the rebroadcast program is conventionally used. It is known (Japanese Patent Laid-Open No. 9-46648). However, this conventional recording device has a problem that recording is prohibited even if the program has not been viewed by the user, if it is a rebroadcast program. In addition, when the broadcast program is a movie, the same movie may be broadcast at another broadcast station, for example, at the same broadcast station two years later, but since these are not rebroadcasts, the above-mentioned conventional In the recording device, the broadcast program is recorded, and unnecessary recording is performed on the recording medium.

Further, in the case where the preference information is weighted, the overlapping programs are selected and recorded with a high priority. However, even if a program is judged to have a high priority, a program that has been judged to have a lower priority but has not been watched than a program watched in the past should actually have a higher priority. However, the above-mentioned conventional recording apparatus cannot cope with such an actual priority.

The present invention has been made in view of the above points,
It is an object of the present invention to provide a recording device and a recording / reproducing device capable of recording a desired program that has not been viewed in the past, thereby eliminating waste of recording and contradiction.

In order to achieve the above object, the first recording device of the present invention obtains a receiving means for selectively receiving a broadcast program of a desired channel and an electronic program guide for the broadcast program. Means, registration means for setting and registering one or two or more pieces of program information including preference information about broadcast programs, and the same program information as the program information registered by the registration means from the electronic program guide obtained by the obtaining means. A detection unit that detects a broadcast program that the user has, a history storage unit that stores a broadcast program that has already been recorded as a history, and a broadcast program that is the same as the broadcast program detected by the detection unit are stored in the history storage unit. Whether the broadcast program is not stored in the history storage means is compared and determined by the comparison determination means and the broadcast detected by the detection means. It is obtained by a configuration having a recording means for recording the program on a recording medium.

According to the present invention, the broadcast program having the same program information as the registered program information detected from the electronic program guide is stored in the history storage means for storing the broadcast program which has already been recorded as the history. Since the broadcast program is recorded in the recording medium when it is not stored, when the broadcast program detected from the electronic program guide is stored in the history storage means, the broadcast program is recorded in the recording medium. Can be banned.

Further, in order to achieve the above object, the second recording apparatus of the present invention is such that when the history storing means of the first recording apparatus exceeds a preset period or a preset number of stored broadcast programs. Then, the stored broadcast programs are deleted in order from the oldest history.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a block diagram of an embodiment of a recording apparatus according to the present invention. The recording device 10 of the present embodiment includes a receiver 11 for selectively receiving a television broadcast signal, a recording unit 12 for recording a received broadcast program of a desired channel output from the receiver 11 on a recording medium, and a receiver 11 Electronic program guide (EPG) multiplexed during the vertical blanking interval (VBI) in the received broadcast signal output from
A program information acquisition unit 13 for acquiring program information from data,
A control unit 14 that controls the operations of the receiver 11 and the recording unit 12.
A user interface (IF) 15 for supplying an instruction signal input by the user to the control unit 14, and a display unit 16
It consists of and. The control unit 14 has a recording reservation list and a history storage memory.

By the way, a television program is usually the original of a broadcasting station. However, movies and the like rarely depend on a broadcasting station, and may be broadcast later on another broadcasting station. In addition, a broadcasting station having a number of channels such as NHK may broadcast the same program by BS and terrestrial waves at different times. The recording device 10 of the present embodiment is adapted to record such a program without duplication.

Next, the operation of the present embodiment will be described with reference to FIG.
It will be described with reference to the flowchart of FIG. First, the user inputs desired genre information via the user IF 15,
The control unit 14 is preset with the priority of registered programs, titles, program times, broadcast stations to be excluded from the beginning, registered preference information such as broadcast stations other than the detected programs, and history limits to be stored. The registration preference information to be set is not limited to one, and a plurality of registration preference information can be set. Further, the limit of the history to be stored can be set arbitrarily, for example, the past four years or the past 100 programs can be set. When the time limit expires, or when the set number of programs is exceeded, the older information is deleted from the history by means such as deletion or overwriting.

In the recording device 10 having the above settings, the receiver 11 receives, for example, a television broadcast signal, and supplies the received signal to the recording unit 12 and the program information acquisition unit 13. The program information acquisition unit 13 extracts, for example, EPG data multiplexed in the vertical blanking interval (VBI) in the received signal as program information and supplies it to the control unit 14. The EPG data includes the title, genre, broadcast station, and broadcast time (program time) of the program broadcast on each channel.
In addition, information such as performers and program contents is included.

The control unit 14 receives the E from the program information acquisition unit 13.
Based on the PG data, among the titles, genres, broadcasting stations, program times, etc. of broadcast programs of all viewable channels,
A broadcast program having the same information as one or more pieces of registered preference information preset and registered by the user is detected (step S1 in FIG. 2), and it is determined whether or not the program can be detected (the same step S1).
2) If this cannot be detected, this process is terminated, and if it is detected, the detected broadcast program is stored in the history storage memory and has already been recorded regardless of whether it has been deleted. Then, a comparison is made to see if there is the same item (step S3 in FIG. 2).

The conditions for determining that the detected broadcast program is in the history storage memory by the comparison determination at this time are as follows. The same genre, title, and broadcasting station (may be on different channels), but different broadcasting stations, but the same title in the movie

Under this condition, when it is determined that the same broadcast program detected based on the registered preference information is not stored in the history storage memory, it is additionally registered in the recording reservation list (step S4 in FIG. 2) and stored. When it is determined that the next program is found, the process returns to the first step S1 to detect the next program based on the preference information.

In this way, the broadcast programs registered in the recording reservation list are displayed on the display unit 16 as a recommended list based on the preference information, and the user selects a broadcast program to be actually recorded from the display recommended list. At the broadcast time of the selected broadcast program, the receiver 1 is controlled under the control of the controller 14.
The signal is selectively received at 1, and the received signal is supplied to the recording unit 12, where it is converted into a predetermined signal form suitable for recording and then recorded on a recording medium. At this time, the control unit 14
Saves the recorded broadcast program in the history storage memory as a history. The recording medium recorded by the recording unit 12 may be a hard disk (HDD), a rewritable disk such as a DVD, a semiconductor memory, an optical disk, or a magnetic tape.

As described above, according to the present embodiment, the recording apparatus 10 does not record the same broadcast program as the broadcast program recorded on the recording medium by the recording unit 12 within the range of the history. Useless recording on the recording medium can be prevented, and the recording capacity of the recording medium having a limited recording capacity can be effectively utilized to the maximum extent. Further, in the case of rebroadcast, it is possible to record even a rebroadcast as long as it is a broadcast program not recorded at the time of main broadcasting.

When the recording medium is an HDD, after the recording capacity is full, the recording is overwritten from the beginning.
In addition, in this embodiment, since the history is stored in the history storage memory in the control unit 14, the recording medium is a replaceable recording medium such as a magnetic tape, and is already recorded on the recording medium before the replacement. Even if the broadcast program is not recorded on the recording medium after the exchange, it is not recorded within the limit of the history, and duplicate recording can be prevented.

The present invention is not limited to the above-mentioned embodiment, and includes various modifications. For example, in the above-described embodiment, the recording device that stores the already recorded broadcast program as a history in the history storage memory has been described. However, when the broadcast program recorded in the recording medium is reproduced, the broadcast program is stored in the history storage memory. It is also possible to configure a recording / reproducing apparatus in which the recording of the broadcast program stored in the history storage memory is prohibited within the limit of the history.

Further, the priority information by weighting is given to the preference information, and the broadcast programs stored as history in the history storage memory have the lowest priority by the above weighting so that the detected broadcast program times overlap. If so, it may be automatically selected according to the above priority. In this case, the broadcast program saved in the history save memory is recorded only when the broadcast time does not overlap with the detected broadcast program, but since it has the lowest priority, wasteful recording will be performed more than before. Can be reduced. Also, if the broadcast time of a broadcast program that has already been recorded as a high priority and a broadcast program that has not been recorded yet and that has a low priority overlap, the priority will be low. However, it is possible to record the broadcast program that has not been recorded yet.

When the broadcast times of a plurality of detected broadcast programs overlap, the broadcast times are displayed on the screen of the display unit regardless of whether the broadcast programs are stored in the history storage memory. A plurality of overlapping broadcast programs may be explicitly displayed, and the user may be allowed to select a broadcast program to be recorded or reproduced. Further, in FIG. 2, instead of creating the recording reservation list, when a broadcast program matching the history is detected from the electronic program guide, a mark or the like is added to create and display the detection list. Good. Furthermore, the acquisition of EPG data is not limited to VBI of broadcast waves,
It can also be obtained from websites on the Internet, data broadcasting of digital broadcasting, and the like.

Further, since the EPG allows reservation of viewing, the broadcast program is saved as a history in the history saving memory at the stage of making the viewing reservation, and
If the broadcast program for which viewing is reserved has been reserved and recorded, it may be removed from the list of reserved recording.
In this case, recording of the broadcast program reserved for viewing is not performed on the recording medium.

[0029]

As described above, according to the present invention,
When a broadcast program having the same program information as the registered program information detected from the electronic program guide is stored in the history storage unit that stores the broadcast program that has already been recorded as a history, Since the recording of broadcast programs on recording media is prohibited, unnecessary recording can be prevented, and in the case of rebroadcast, if it is a broadcast program that was not recorded during the main broadcast, it is saved as history. Since it is not, it can be recorded even for reruns.

Further, according to the present invention, the history storing means is
When the preset period or the preset number of stored broadcast programs is exceeded, the stored broadcast programs are deleted in order from the oldest one, thereby limiting the history and setting the storage capacity of the history storage means. Since the value can be less than or equal to the value, a storage device having an inexpensive structure can be used as the history storage means.

Further, according to the present invention, a broadcast program having the same program information as the registered program information detected from the electronic program guide is displayed as a recording reservation list and selected from the displayed broadcast programs. Since only the inputted broadcast program is recorded on the recording medium, it is possible to prevent unnecessary recording and record according to the intention of the user.

Further, according to the present invention, a plurality of broadcast programs having the same program information as the registered program information and having overlapping broadcast times are displayed, and the broadcast program to be recorded is selected and input from the plurality of broadcast programs. You can prevent useless recording,
It is possible to record according to the intention of the user.

Further, according to the present invention, the broadcast program having the same program information as the registered program information detected from the electronic program guide is given a priority according to the registered information and is stored in the history storage means. By assigning the lowest priority to the broadcast program and automatically selecting the highest priority broadcast program among the multiple broadcast programs with the detected broadcast times overlapping and recording it on the recording medium, Even if the frequency is high, the broadcast program stored in the history storage means has the lowest priority. Therefore, the broadcast program that has already been recorded and has been judged to have the highest priority, and has not been recorded yet. If the broadcast times of the broadcast programs that are determined to have low priority overlap, the broadcast program that has not been recorded even if the priority is low can be recorded.

Further, according to the present invention, a broadcast program having the same program information as the registered program information detected from the electronic program guide is recorded in a recording medium, and is stored as a history when the broadcast program is reproduced from the recording medium. By doing so, broadcast programs that have been recorded on the recording medium but have not been viewed are not saved as history, so that it is possible to prevent unnecessary recording of broadcast programs that are more practical.
