Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a recording apparatus and a recording / reproducing apparatus, and more particularly to a recording apparatus and a recording / reproducing apparatus having a function of obtaining an electronic program guide (EPG) and a function of recording a television broadcast program of a desired channel.
[0002]
[Prior art]
In a known personal video recorder (PVR) that records a television broadcast program in a digital format on a built-in hard disk, a genre or the like that matches the user's preference is registered. It has a so-called favorite recording or agent function that automatically records broadcast programs of the same genre in each channel.
[0003]
[Problems to be solved by the invention]
However, in the conventional recording apparatus such as the above-described PVR, all programs that match the registered preference information are targets, and even programs that have already been viewed in the past are programs that match the registered preference information. If so, there is a problem in that useless recording is performed.
[0004]
Also, in the case of a rebroadcast program, a program that matches the registered preference information is recorded. However, if it is only necessary not to record a rebroadcast, an identification code for rebroadcast is provided in a packet header or the like. (Or a flag) is inserted and broadcasted, and when a re-broadcasting identification code (or flag) is detected on the receiving side, a recording apparatus that prohibits recording of the re-broadcast program has been conventionally known. (Japanese Patent Laid-Open No. 9-46648). However, this conventional recording apparatus has a problem that even if the program has not been viewed by the user, recording is prohibited when the program is a rebroadcast program. Also, when the broadcast program is a movie, the same movie may be broadcast on another broadcast station, or may be broadcast on the same broadcast station, for example, two years later. In the recording device, the broadcast program is recorded, and useless recording is performed on the recording medium.
[0005]
Further, when the preference information is weighted, a duplicate program having a high priority is selected and recorded. However, even if a program is judged to have a high priority, a program that has been judged to have a lower priority than a program that has been viewed in the past but has never been viewed should actually have a higher priority. The above conventional recording apparatus cannot cope with such an actual priority.
[0006]
The present invention has been made in view of the above points, and provides a recording apparatus and a recording / reproducing apparatus capable of recording a desired program that has not been viewed in the past, thereby eliminating recording waste and contradiction. Objective.

[0015]
DETAILED DESCRIPTION OF THE INVENTION
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 apparatus 10 according to the present embodiment includes a receiver 11 that selectively receives a television broadcast signal, a recording unit 12 that records a received broadcast program of a desired channel output from the receiver 11 on a recording medium, and the receiver 11. A program information acquisition unit 13 for acquiring program information from electronic program guide (EPG) data multiplexed during a vertical blanking interval (VBI) in a received broadcast signal output from the receiver 11, and a receiver 11 and a recording unit 12 The control unit 14 controls the operation of the user, a user interface (IF) 15 that supplies an instruction signal input from the user to the control unit 14, and a display unit 16. The control unit 14 has a recording reservation list and a history storage memory.
[0016]
By the way, a television program is usually an original of a broadcasting station. However, movies and the like are rarely dependent on a broadcasting station, and may be broadcast later on another broadcasting station. In addition, a broadcasting station having several channels such as NHK may broadcast the same program on the BS and the terrestrial at different times. The recording apparatus 10 according to the present embodiment records such a program without duplication.
[0017]
Next, the operation of the present embodiment will be described with reference to the flowchart of FIG. First, the user saves the desired genre information via the user IF 15, the priority when the detected program is duplicated, the title, the program time, the registered preference information of the broadcasting station excluded from the beginning, other broadcasting stations, and the like. The limit of the history to be set is preset in the control unit 14. Note that 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 arbitrarily set, for example, the past 4 years or the past 100 programs can be set. When the program expires or the number of set programs is exceeded, the older information is deleted from the history by means such as deletion or overwriting.
[0018]
The recording apparatus 10 set as described above receives, for example, a television broadcast signal by the receiver 11 and supplies the reception signal to the recording unit 12 and also to the program information acquisition unit 13. The program information acquisition unit 13 extracts EPG data multiplexed in, for example, the vertical blanking interval (VBI) in the received signal as program information and supplies the program information to the control unit 14. The EPG data includes information such as the performer and the contents of the program in addition to the title, genre, broadcast station, and broadcast time (program time) of the program broadcast on each channel.
[0019]
Based on the EPG data from the program information acquisition unit 13, the control unit 14 sets one or two or more registrations that are set and registered in advance by the user among the broadcast program titles, genres, broadcast stations, program times, etc. of all viewable channels. A broadcast program having the same information as the preference information is detected (step S1 in FIG. 2), and it is determined whether or not it has been detected (step S2). If it cannot be detected, this process is terminated. Whether or not the program is stored in the history storage memory is the same as the broadcast program that has already been recorded regardless of whether or not it has been erased (step S3 in FIG. 2).
[0020]
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.
(1) The genre, title, and broadcasting station (channels may be different) are the same. (2) The broadcasting station is different, but the title is the same in the movie.
If it is determined that the same broadcast program detected based on the registered preference information under this condition is not stored in the history storage memory, it is additionally registered in the recording reservation list (step S4 in FIG. 2) and stored. If it is determined, the process returns to the first step S1, and the next program is detected based on the preference information.
[0022]
In this way, the broadcast program registered in the recording reservation list is displayed on the display unit 16 as a recommendation list based on preference information, and the user selects a broadcast program to be actually recorded from the display recommendation list. When the broadcast time of the selected broadcast program comes, it is selectively received by the receiver 11 under the control of the control unit 14, and the received signal is supplied to the recording unit 12, where it is converted into a predetermined signal format suitable for recording. Is recorded on a recording medium. At this time, the control unit 14 stores the recorded broadcast program as a history in the history storage memory. The recording medium recorded by the recording unit 12 may be any of a hard disk (HDD), a rewritable disk such as a DVD, a semiconductor memory, an optical disk, and a magnetic tape.
[0023]
Thus, according to the present embodiment, the same broadcast program as the broadcast program recorded on the recording medium by the recording device 12 by the recording device 10 is not recorded within the limit of the history. Can be prevented, and the recording capacity of a recording medium with a limited recording capacity can be utilized to the maximum. In the case of rebroadcasting, a broadcast program that is not recorded at the time of the main broadcast can be recorded even if it is a rebroadcast.
[0024]
When the recording medium is an HDD, after the recording capacity is full, it is overwritten from the beginning. 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 has already been recorded on the recording medium before the replacement. Even if the broadcast program is not recorded on the exchanged recording medium, it is not recorded within the limit of the history, and duplication recording can be prevented.
[0025]
The present invention is not limited to the above-described embodiment, and includes other various modifications. For example, in the above embodiment, the recording apparatus that stores the already recorded broadcast program as a history in the history storage memory has been described. However, when the broadcast program recorded on 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 that stores as a history and prohibits recording of broadcast programs stored in the history storage memory within the limits of the history.
[0026]
In addition to giving priority to preference information by weighting, broadcast programs stored as history in the history storage memory have the lowest priority by weighting, and the times of detected broadcast programs overlapped. In such a case, the automatic selection may be performed according to the above priority. In this case, the broadcast program stored in the history storage memory is recorded only when the detected broadcast program and the broadcast time do not overlap, but the priority is the lowest, so useless recording is compared to the conventional one. Can be reduced. Also, if the broadcast time of a broadcast program that has already been recorded with a high priority and a broadcast program with a low priority that has not been recorded yet overlap, the priority is low. However, it is possible to record the broadcast program that has not been recorded yet.
[0027]
In addition, when the broadcast times of a plurality of detected broadcast programs overlap, the broadcast time overlaps on the screen of the display unit regardless of whether or not the broadcast program is stored in the history storage memory. A plurality of broadcast programs may be explicitly displayed so that the user can select a broadcast program to be recorded or reproduced. In FIG. 2, when a broadcast program matching the history is detected from the electronic program guide instead of creating a recording reservation list, a detection list is created and displayed with a mark or the like. Good. Furthermore, EPG data can be acquired not only from broadcast wave VBI, but also from a Web site on the Internet, data broadcasting of digital broadcasting, and the like.
[0028]
Furthermore, since the EPG can be reserved for viewing, the broadcast program is stored as a history in the history storage memory when the viewing is reserved, and the broadcast program for which viewing is reserved is reserved for recording. If it has been done, it may be removed from the list of reserved recordings. In this case, the broadcast program for which viewing reservation has been made is not recorded on the recording medium.
[0029]
【The invention's effect】
As described above, 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 stored as a history of broadcast programs that have already been recorded. When the program is stored in the history storage unit, recording of the broadcast program on the recording medium is prohibited, so that unnecessary recording can be prevented and, in the case of re-broadcasting, the program is recorded during the main broadcast. If it is a broadcast program that has not been broadcast, it is not stored as a history and can be recorded even if it is a rebroadcast.
[0030]
Further, according to the present invention, the history storage means is configured to delete the stored broadcast programs in order from the oldest history when the preset period or the preset number of stored broadcast programs is exceeded. Since the storage capacity of the history storage unit can be set below the set value, a storage device with an inexpensive configuration can be used as the history storage unit.
[0031]
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 is selected and input from the displayed broadcast programs. Since only the broadcast program is recorded on the recording medium, unnecessary recording can be prevented and recording according to the intention of the user can be performed.
[0032]
In addition, according to the present invention, a plurality of broadcast programs having the same program information as the registered program information and overlapping broadcast times are displayed, and a broadcast program to be recorded is selected and input from among them. Can be prevented and recording can be performed according to the user's intention.
[0033]
Further, according to the present invention, a priority corresponding to the registered information is given to the broadcast program having the same program information as the registered program information detected from the electronic program guide, and the broadcast program stored in the history storage unit is given. The highest priority is given to the registered information by automatically selecting the highest priority broadcast program among the multiple broadcast programs with the lowest priority and overlapping the detected broadcast times and recording them on the recording medium. However, since the broadcast program stored in the history storage means has the lowest priority, the broadcast program already determined to have a high priority and the priority that has not yet been recorded. If the broadcast times of broadcast programs determined to be low overlap, it is possible to record the broadcast program that has not yet been recorded even if the priority is low.
[0034]
Furthermore, 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 on a recording medium, and is stored as a history when the broadcast program is reproduced from the recording medium. Since broadcast programs that have been recorded on a recording medium but have not been viewed yet are not saved as history, it is possible to prevent useless recording of broadcast programs that are more realistic.
