BACKGROUND OF THE INVENTION
The present invention relates to a recording apparatus, and more particularly to a recording apparatus having an electronic program guide (EPG) acquisition and display function and a function of recording a video signal of a broadcast program.
[0002]
[Prior art]
In storage-type data broadcasting, updating of the latest digest news information at the same broadcasting station is being considered. In this case, the latest digest news information of the same broadcast station can be viewed. This is equivalent to what has already been done with a known personal video recorder (PVR) that records a television broadcast program in digital form on an internal hard disk. On the other hand, it is already known that the PVR has a favorite recording and agent function for recording a number of broadcast signals of the same genre of various channels.
[0003]
[Problems to be solved by the invention]
However, in the case of the above-described storage type data broadcasting, the digest news information to be updated is transmitted from the same broadcasting station, and therefore depends on the updating cycle of the broadcasting station. However, viewers usually get news and weather forecast information on TV, if they happen to broadcast it when they want to watch it, they usually watch it without regard to the broadcasting station, and digests from the same broadcasting station News information is not always up to date when viewers want to see it.
[0004]
In addition, PVR's favorite recording and agent function, when recording broadcast signals of desired genres (for example, news and weather forecasts) of all channels, the number of programs is so large that the recording medium becomes full immediately. End up.
[0005]
The present invention has been made in view of the above points, and an object thereof is to provide a recording apparatus capable of recording a broadcast program of a desired genre with an inexpensive configuration without depending on a broadcasting station.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a first recording apparatus of the present invention comprises a receiving means for selectively receiving a broadcast program of a desired channel, an obtaining means for obtaining an electronic program guide relating to the broadcast program from the outside, and a plurality of broadcasting stations. Detecting means for detecting a program of one or more preset genres that are broadcast separately on the basis of the electronic program guide obtained by the obtaining means, and a signal of the broadcast program received by the receiving means Is recorded in a preset recording area of the recording medium, and a program of the set genre detected by the detecting means is received by the receiving means, and a signal of the received program is preset by the recording means And a control means for overwriting and recording in the recording area.
[0007]
In this invention, since the program of the same genre is received regardless of the broadcasting station and is overwritten and recorded in a preset recording area of the recording medium, the setting received last without depending on one broadcasting station. The signal of the genre program can be held in the recording area of the recording medium.
[0008]
In order to achieve the above object, in the second recording apparatus of the present invention, a signal of a received program of the set genre detected by the detecting means is preset by the recording means. The recording area is overwritten for a predetermined time. In the present invention, a signal of a received program of a set genre is recorded for a limited time in a limited recording area.
[0009]
In order to achieve the above object, the third recording apparatus of the present invention uses the control means described above for a received program having a preset genre detected by the detection means and having a preset broadcast time. The signal is overwritten and recorded in a recording area set in advance by a recording means. In the present invention, among the received programs of the set genre, only the received program signal of the set broadcast time is recorded in a limited recording area.
[0010]
In order to achieve the above object, the fourth recording apparatus of the present invention obtains the acquisition means from the vertical blanking period of the received television broadcast signal, the site on the Internet, or the digital broadcast data broadcast. The electronic program guide is obtained.
[0011]
In order to achieve the above object, the fifth recording apparatus of the present invention executes the control unit when the recording unit is not used to perform overwriting recording of the program signal in a preset recording area. It is characterized by that.
[0012]
In order to achieve the above object, the sixth recording apparatus of the present invention further includes priority designation means for designating a priority when programs of the set genre detected by the detection means overlap. When the program of the set genre detected by the detection means overlaps, the control means overwrites and records the signal of the program designated by the priority designation means in a recording area preset by the recording means. It is characterized by having a configuration to be made. In the present invention, a program of a desired genre can be recorded in a priority order according to the user's intention.
[0013]
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 signal of a desired channel output from the receiver 11 on a recording medium, and a receiver. A program information acquisition unit 13 for acquiring program information from electronic program guide (EPG) data multiplexed during a vertical blanking interval (VBI) in the received broadcast signal to be output, and the receiver 11 and the recording unit 12 The control unit 14 controls the operation, and a user interface (IF) 15 that supplies an instruction signal input from the user to the control unit 14.
[0014]
The recording apparatus 10 of the present embodiment detects desired genre information from the genre information of EPG data, and the recording unit 12 overwrites and records the broadcast signal of the desired genre information in a certain area secured on the recording medium. It is a thing.
[0015]
Here, the EPG has main genre information, and is classified into, for example, movies, sports, dramas, anime, cuisine, variety, quizzes, news, travel, weather forecasts, and the like. Note that news programs vary from spot news for several minutes to news programs of more than one hour, but in this embodiment, the programs are mainly for short-time programs. It is assumed to record a program that immediately finishes watching the content at 5 times speed or the like.
[0016]
Next, based on the above, the operation of the present embodiment will be described. First, the user secures a recording area for recording an amount of information on the recording medium in the recording unit 12 via the user IF 15 so that the content can be immediately viewed at 1.5 times speed with audio. The recording in the recording area set by the user is executed when the recording apparatus 10 is not used for other recording operations, other normal reserved recording, or the like.
[0017]
Now, the genre information desired by the user via the user IF15, the broadcast time frame of the program of the genre information, the priority when the detected program is duplicated, the broadcast station to be excluded from the beginning, the program over the specified time Information such as whether to exclude or whether to record because it may be cut off during the program is set in the control unit 14. Here, the genre information targeted by the present embodiment is the same genre information that is updated in a relatively short time and is broadcast separately by a plurality of broadcasting stations. For example, news, weather forecast and so on. The weather forecast broadcast in the news program is included in the news genre. The genre of the weather forecast is a weather forecast program. The genre information to be set is not limited to one, and a plurality of genre information can be set.
[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 program content in addition to the title, broadcast time, and genre of the program broadcast on each channel.
[0019]
The control unit 14 detects genre information in which all viewable channels are set, that is, a news program, from the genre information of the EPG data, and causes the receiver 11 to selectively receive the detected news program. As a result, the reception signal of the news program received by the receiver 11 is supplied to the recording unit 12, where it is converted into a predetermined signal format suitable for recording, and then overwritten on a previously secured recording area of the recording medium. To be recorded.
[0020]
In this way, every time a news program is broadcast in any of the channels that can be viewed, the news program is overwritten and recorded in a recording area reserved in advance in the recording medium. In this reserved recording area, only the latest news program is always recorded and held regardless of the channel (broadcast station). Therefore, by reproducing this recording area of the recording medium, the latest news and weather forecast can be viewed without depending on the update cycle of one broadcasting station.
[0021]
Note that the present invention is not limited to the above-described embodiment. For example, EPG data can be acquired not only from broadcast wave VBI but also from the Internet or digital broadcast data broadcast. Further, not only when a news program for a predetermined time (information amount) is overwritten and recorded in a recording area secured on the recording medium, but only a news program with a predetermined broadcast time or less may be overwritten and recorded. Also, the present invention can be applied to digital broadcasting and data broadcasting as well as analog broadcasting. Also, the present invention can be applied to digital radio broadcasting if a program guide is available.
[0022]
The genre information to be detected is not limited to news programs and weather forecast programs, but may be traffic information of digital radio broadcasts. Since digital radio broadcasting has traffic information at regular intervals, by applying the present invention, the latest traffic information can be reproduced from the recording medium regardless of the broadcasting station when the user wants to know.
[0023]
【The invention's effect】
As described above, according to the present invention, a program of the same genre is received regardless of a broadcasting station, and is overwritten in a preset recording area of a recording medium, thereby depending on one broadcasting station. Since the signal of the program of the set genre received last is held in the recording area of the recording medium, the program of the latest set genre can always be reproduced from the recording medium. Further, since only a limited recording area of the recording medium is used, another recording area of the same recording medium can be used for recording different information, and it is inexpensive even if the user does not purchase an expensive digital broadcasting compatible device. The program of the latest setting genre can be reproduced from the recording medium with the configuration.
[0024]
Further, according to the present invention, the signal of the program designated by the priority designation means is overwritten and recorded in a recording area set in advance by the recording means, so that the desired priority order according to the user's intention can be obtained. Therefore, a user-friendly recording device can be realized.
