(First Embodiment) An outline of the first embodiment will be described with reference to FIG. 1. In the present embodiment, program information on a broadcast program published in a newspaper or a TV guide magazine is displayed (program list for each channel). A so-called timer-on reservation that plays back a CD-ROM stored together for one month, searches for a TV program, and turns on the power at a predetermined time of a reserved program. Is what you do.

The television receiver AA shown in FIG. 1 is an embodiment in which a CD-ROM reproducing section 11 according to the gist of the present invention is incorporated, for example, and an image is displayed on the front surface thereof. Display unit 5, a speaker 7 for outputting sound, a light receiving unit 4 for receiving output light of a remote controller 40, and a CD-ROM 1 on which broadcast program information is recorded.
A CD-ROM playback unit 11 for playing back the CD-ROM 10 is provided. Then, the operator displays necessary information in the broadcast program information recorded on the CD-ROM 110 on the display unit 5 by operating the remote controller 40, selects it, and reserves the current channel and program. Can be.

Here, the configuration of the television receiver AA will be described in detail with reference to FIG. 2. A broadcast signal is supplied from an antenna 1 to a tuner unit 2, and a selection signal 3a supplied from a control unit 3 is transmitted to the tuner unit 2. A video and audio signal 2a obtained by demodulating a broadcast signal related to the channel.
Is supplied to the signal processing unit 6. It is assumed that the tuner unit 2 has preset a channel preset for a broadcast station that can be received in that area.

The signal processing section 6 outputs the video / audio signal 2
a and a program display signal 3b to be described later, a video signal 6a obtained by performing predetermined processing is supplied to the display unit 5, and an audio signal 6b is supplied to the speaker 7. The control unit 3 includes a power supply unit 8 for controlling power supply, a clock unit 9 for outputting the current time, a memory unit 10 for storing necessary information, and a CD-ROM.
The reproducing unit 11 and the light receiving unit 4 are connected.

Next, the mutual relationship between these components will be described with reference to FIG. 3 which shows a flowchart of the current channel and program reservation. First, in step S1, the current channel selection and program reservation are started by operating a predetermined switch of the remote controller 40. Step S1
Is completed, the process proceeds to step S2.

In step S2, step S4 described later
Clock data 9 representing the current time serving as a search condition in
The control unit 3 reads “a” from the clock unit 9 and stores the clock data 9a in the memory unit 10 from there. When step S2 ends, the process proceeds to step S3.

In step S3, the channel data 2b of the broadcast station which can be received in that area, which is the search condition in step S4, is read into the control unit 3 from the tuner unit 2, and the channel data is stored in the memory unit 10 therefrom. The data 2b is stored. Here, the channel data 2b is stored in the tuner 2
, And is data in which a channel number specified by a numeric keypad or the like of the remote controller 40 and a broadcast station number indicating a broadcast station are paired, for example, the channel number “1” and the broadcast station. The broadcasting station number “100” representing NHK is paired. When step S3 ends, the process proceeds to step S4.

In step S4, the clock data 9a stored in the memory unit 10 in steps S2 and S3 and the local
Using the receivable channel data 2b as a search condition, the control unit 3 reproduces the CD-ROM 110 by the CD-ROM reproducing unit 11 and reads out the necessary broadcast program information signal 11a. That is, it searches for broadcast program information including a current time and a future time that can be reserved for a timer. Where C
The storage state of the program information in the D-ROM 110 has a hierarchical structure. For example, there is a hierarchy for each time under a hierarchy for each broadcasting station, and a hierarchy for the program contents thereunder. Also, there may be a hierarchy for each broadcasting station below a hierarchy for each time, and a hierarchy for the program contents thereunder. Then, a future program including the time indicated by the clock data 9a and a program of a broadcasting station indicated by the channel data 2b is read. When step S4 ends, the process proceeds to step S5.

In step S5, the necessary broadcast program information signal 11a read in step S4 is stored in the memory unit 10. When step S5 is completed, step S5 is performed.
Proceed to 6.

In step S6, the control section 3 reads out information necessary for displaying a program guide from the memory section 10 out of the broadcast program information signal 11a stored in the memory section 10 in step S5, and outputs the information as a program display signal 3b. The signal is supplied to the processing unit 6, where the signal is subjected to predetermined signal processing and displayed on the display unit 5. As shown in FIG. 4, the display screen displays the current time information (including the date and the day of the week) with the broadcast station name,
It is simply represented as a broadcast time and a title. Then, using the remote controller 40, the arrow on the display screen is moved to the title of the program currently being broadcast, and is determined by the determination switch in the remote controller 40, so that the determined broadcast program information for each program is displayed. A selection signal 3a is supplied from the control unit 3 to the tuner unit 2 and a video / audio signal 2a obtained by tuning to the determined broadcasting station is output to the signal processing unit 6 and is switched to a desired channel. Channel selection and program reservation are completed. When step S6 ends, the process proceeds to step S7.

In step S7, if there is no desired program as a result of viewing the display of the program guide, it is determined whether or not to end the program. In the case of terminating, the arrow shown in FIG. 4 is moved to the “end” column in the upper right corner and determined, thereby terminating the process.
If completed, the process proceeds to step S14, where the current channel selection and program reservation are completed. On the other hand, if the end is not selected, the process proceeds to step S8.

Here, the order of steps S8, S10 and S12 is provided for convenience of explanation, and if not actually ended in step S7, "commentary", "program reservation", and "item Move the arrow to the column of "", and proceed to selection S8, S10, S12, and then proceed to steps S9, S11, S13 respectively.

First, step S9 is a case in which the program reservation is selected in step S8. When the arrow is moved to a desired program title and confirmed, the control unit 3 performs the reservation processing of the decided program. This reservation process has been confirmed
This is performed based on the broadcast program information for each program, and the start time and end time of the program and the type of the broadcast station are stored in a memory dedicated to reservation (not shown) in the control unit 3. It is done by doing. Then, the control unit 3 compares the current time with the determined start time of the program, and when the two coincide with each other, the control unit 3 outputs a command to input power to the power supply unit 8 and indicates the channel to the tuner unit 2. By outputting the selection signal 3a to the selection control unit 3, a so-called on-timer function is executed. Then, step S9
Is completed, the process proceeds to step S7, and this is repeated.

In step S11, an explanation is given in step S11.
In the case where the selection is made in step 10 and the arrow is moved to the desired program title and confirmed, the detailed individual commentary of the program content corresponding to the program title is read out from the memory unit 10, and the currently displayed screen is displayed. It is synthesized, and it is
This is displayed on the display unit 5 via the signal processing unit 6. This display screen includes detailed individual explanations surrounded by dotted lines as shown in FIG. When step S11 ends, the process proceeds to step S7, and this is repeated.

Step S10 is a case where item selection is selected in step S12, and a screen shown in FIG. 5 is displayed, so that large items (eg, genre, cast, etc.) can be known. When the arrow is further moved to the displayed item and confirmed, the details of the corresponding item are read from the memory unit 10 by the control unit 3 and displayed on the display unit 5 via the signal processing unit 6. For example, when "anime" is selected as shown in FIG. 5, the current time information (including date and day of the week) relating to the animation shown in FIG. 6 is simply represented as a broadcast station name, broadcast time, title, and the like. The program guide is displayed. When step S10 ends, the process proceeds to step S7, and this is repeated.

In this way, the operator can easily reserve the current channel and program only by selecting the information displayed on the display unit 5. In the above-described embodiment, the CD-ROM playback unit 11 is
Needless to say, such a configuration may be provided.

(Second Embodiment) In a second embodiment, recording reservation of a VTR is performed using the above-described television receiver AA, and will be described with reference to FIG.

The television receiver A1 shown in the figure has all the functions of the above-mentioned television receiver AA, and further has a function of instructing a VTR with a BB code to record.

That is, when "recording reservation" is selected while the program guide shown in FIG. 4 is displayed on the display unit 6 of the television receiver A1, the same as in the case of the program reservation described above, The channel and the start and end times are stored in the reserved recording area.

At the start time of a predetermined broadcast program, the light emitting unit 15 of the television receiver A1 emits infrared light having a recording start command to the light receiving unit 16 of the VTR. The recording start instruction includes an instruction to turn on the power of the VTR, an instruction to select a channel of the tuner unit in the VTR, and an instruction to start recording.

At the end time, the light emitting section 15 of the television receiver A1 emits an infrared ray having a recording end command to the light receiving section 16 of the VTR. The recording end command includes a command to end recording and a command to turn off the power of the VTR. If a plurality of broadcast programs are reserved, this is repeated.

Now, in order for the television receiver A1 to have such a function, the television receiver A1 needs to transmit a remote control code of the VTR (for example, power on / off, recording, stop, channel selection, timer reservation, etc.) in advance. Although it is necessary to know, these remote control codes input a command transmitted by the VTR remote control 41 to the control unit 3 via the light receiving unit 4 of the television receiver A1, and here, a well-known remote control learning function is performed. This is performed by storing the remote control code in the memory unit 10 using the remote control code. Alternatively, a predetermined code for each manufacturer may be stored in the memory unit 10 in advance.

It is to be noted that light may not be transmitted depending on the positional relationship between the television receiver A1 and the VTR. In such a case, a reflecting plate is appropriately installed, or
If the light emitting section 15 is made detachable from the television receiver A1 and both are connected by an extension cable, the light emitting section 15 can be installed in front of the light receiving section 16 of the VTR, and such a problem can be solved.

In this embodiment, the recording start command and the recording end command are transmitted to the VTR. However, the timer reservation code may be directly transmitted to the VTR. In such a case, the memory unit in the television receiver A1 is used. Since it is not necessary to set the recording reservation area in 10, the configuration can be simplified.

In the first and second embodiments described above,
The medium in which the broadcast program is stored has been described as an example of a CD-ROM. However, the medium is not limited to this as long as information on the broadcast program is stored in this medium. Needless to say, the information medium may be a disk, a floppy disk, a ROM, or the like.

[0034]

As described above, according to the configuration of the present invention,
In particular, current time information and broadcasts that can be
As the search condition, the broadcast station information preset as a station includes the current time from the broadcast program information.
A control section for selecting timer-reservable broadcast program information related to a future time, and displaying the broadcast program information selected by the control section, so that past broadcast program information unnecessary for program selection and Since the broadcast program information relating to the broadcast station that cannot be selected by the tuner unit is not displayed, only the necessary information can be provided to the operator, and the broadcast program can be easily selected.
