Abstract

PROBLEM TO BE SOLVED: To allow the receiver to make selection reflecting intention of the user on the occasion in the case of revising a reserved program or a currently viewing program in the digital broadcast receiver that reserves programs by the user. SOLUTION: A processor 7 gives information about a start time, a broadcast time, a CH name, a program name of a currently received program extracted from additional information in a received signal to a view program end time detection circuit 8, where the end time is calculated and the result is fed to a comparator circuit 9 with the CH name. The processor 7 reads setting reservation information from a nonvolatile storage device 12 and gives the information to a reservation start time detection circuit 10, where the CH name and the start time are extracted and given to the comparator circuit 9. When the comparator circuit 9 discriminates different CH names, the circuit 9 compares the reservation start time with the end time of the currently received program. When the times are in duplicate, the circuit 9 provides a detection signal. The processor 7 receiving the detection signal informs the user of it by means of a notice method such as an indicator or display on a received image that is selected by the user on an initial setting menu of the receiver.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a digital broadcast receiving apparatus according to the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a block diagram showing an outline of a configuration of a digital broadcast receiving apparatus according to an embodiment of the present invention. A digital broadcast signal transmitted from a broadcast station is received by an antenna 1. The signal received by the antenna 1 is supplied to a tuner 2. The tuner 2 performs a process of extracting a designated channel, baseband conversion, AD conversion, demodulation, and error correction, and then supplies the signal to a demultiplexer 3. The received signal is multiplexed with audio information, video information, and other additional information by a broadcasting station. The demultiplexer 3 separates each original information before multiplexing from the multiplexed received signal, and further distributes the information. The audio information and the video information therein are decoded by the AV decoder 4 and supplied to the display control circuit 5. On the other hand, the microprocessor 7 supplies a screen display request signal to the display control circuit 5 based on additional information included in the broadcast information and an input instruction from the input device 11 (for example, a remote controller).

The microprocessor 7 writes and stores initial setting information, reservation information, and the like in the nonvolatile storage device 12 as necessary, or reads information stored therein. The display control circuit 5 includes a microprocessor 7
In response to the screen display request signal supplied from the AV decoder 4, the video signal for screen display is superimposed on the video signal of the program supplied from the AV decoder 4 and supplied to the encoder 6. The encoder 6 converts the supplied video signal into a format such as NTSC and outputs it. The user can view video and audio on a display device 14 such as a television connected to the digital broadcast receiving device.

As described above, this digital broadcast receiving apparatus uses not only video information of a program but also more detailed information on the basis of additional information multiplexed on a received signal from a broadcast station under the control of the input device 11, for example. The information can be displayed on a display device 14 such as a television connected to the digital broadcast receiving device. The additional information multiplexed on the received signal of the signal transmitted from the broadcasting station is composed of information such as the broadcast start time of the program, the broadcast time, the program name, the broadcast channel name, and the detailed contents of the program. In this digital broadcast receiving apparatus, for example, an input device 1 such as a remote controller
When an instruction is given through the display device 1, a broadcast schedule table for a future time zone is constructed from the additional information described above, and the display device 14 such as a television connected to the digital broadcast receiving device is used.
Can be displayed.

Further, the digital broadcast receiving apparatus uses a non-volatile input terminal 11 to change the broadcast start time, broadcast time, program name, broadcast channel name and the like of a program in accordance with a user's instruction to select a desired program. It is possible to store the reservation information in the storage device 12 and delete the reservation information stored in the nonvolatile storage device 12. Further, since the additional information also includes the current time information, the digital broadcast receiving apparatus checks the current time information and the reservation information including the reservation time stored in the nonvolatile storage device 12, It is possible to execute the reservation of the program related to the reserved information. Note that the above functions are functions that the conventional one has, and the same operation is performed in the embodiment of the present invention.

FIG. 2 shows an example of a digital broadcast broadcast schedule received by the digital broadcast receiving apparatus according to the present invention. In FIG. 2, CH1, CH
2 and CH3 are channel names.
-2, Program 2-1, Program 2-2, Program 2-3, Program 3-
1, program 3-2 and program 3-3 are program names. In CH1, the program 1-1 is scheduled to be broadcast for one hour from pm7: 30, and the program 1-2 is scheduled to be broadcast for two hours from pm8: 00.
In CH2, program 2-1 is 1 hour from 7:00 pm, program 2-2 is 30 minutes from 8:30 pm, and program 2-3 is pm
It is scheduled to be broadcast for one hour from 9:00. CH
In program 3, program 3-1 is 1 hour from 7:00 pm, program 3 is
2 is 1 hour from 8:00 pm, program 3-3 is 9:00 pm
It will be broadcast from 0 to 1 hour.

In this broadcast schedule, the user has set the reservation of the program 2-2 of CH2 and the program 3-3 of CH3 in the digital broadcast receiving apparatus, and the user has set the program 1-1 of CH1. Started watching at 7:30 pm
It is assumed that the program 1-1 ends at 8:00 pm and the program 1-2 starts. The program name currently viewed by the user is changed from program 1-1 to program 1-2, and the broadcast start time of the program currently viewed by the user is changed from 7:00 pm to 8:00 pm However, this can be obtained from information added to the broadcast signal. When these changes occur, the microprocessor 7 supplies an information change signal to the viewing program end time detection circuit 8 and the reservation start time detection circuit 10.

Further, the microprocessor 7 supplies information on the start time, broadcast time, channel name and program name of the currently received program extracted from the additional information in the received signal to the viewing program end time detecting circuit 8. That is, the information to be supplied in this case is pm on December 1, 1997, respectively.
8:00, 2 hours, CH1, Program 1-2. Then, the viewing program end time detection circuit 8 calculates the end time from the information supplied by the microprocessor 7 and supplies it to the comparison circuit 9 together with the channel name. In this case CH
1, pm 10:00 on December 1, 1997. Further, the microprocessor 7 reads the reservation information from the nonvolatile storage device 12 and supplies it to the reservation start time detection circuit 10. Then, the reservation start time detection circuit 10 extracts the channel name and the start time from all the reservation information and supplies them to the comparison circuit 9. In this case, CH2, 1997 1
Pm 8:30 on February 1 and CH3, December 1, 1997
It is 9:00 pm on the day.

The comparison circuit 9 has information on the channel name of the program currently being viewed, in this case, CH1 and information on the channel names of all the programs for which reservation has been set, in this case, C1.
Compare H2 and CH3. If the channel names are different, the start time of the reservation is compared with the end time of the currently received program. In this case, the program 2 of CH2
2 reservation start time, December 1, 1997 pm8: 30
And the reservation start time of the program 3-3 on CH3, January 1, 1997
End time of the program receiving 9:00 pm on February 1,
It is compared with pm 10:00 on December 1, 1997, respectively. As a result of the comparison, when the reservation start time is earlier, the comparison circuit 9 supplies the microprocessor 7 with the reservation channel name and the start time in which the signal of the overlap detection of the reserved program and the viewed program is duplicated. In this case, program 2-2, program 3-3
In both cases, the start time of the reserved program is earlier, and 199 of CH2
Pm8: 30 on December 1, 2007 and CH3 on January 1, 1997
It supplies information on two reservations at 9:00 pm on February 1.

The microprocessor 7 which has received the overlap detection signal from the comparison circuit 9 gives a notification using the notification method set by the user on the initial setting screen shown in FIG. In the example shown in FIG. 3, as a method of notifying a user when a reservation is made during a viewing program, a screen display, lighting of an indicator, or execution of a reservation without notification can be selected. Here, for example, if the setting is to notify using a screen display, the microprocessor 7 supplies the information on the start time of the duplicate reservation supplied from the comparison circuit 9 and the reservation information to the reservation start time detection circuit 10. At this time, all the reservation information stored in the built-in volatile storage area is compared. The microprocessor 7 configures screen display video information for superimposing the video information of the program based on the matching reservation information as a result of the comparison, and supplies a screen display request signal to the display control circuit 5. Thereafter, both the display control circuit 5 and the encoder 6 operate in the same manner as in the related art, and a screen as shown in FIG. 4 is superimposed and displayed on the video of the program 1-2 being viewed.

In the reservation deletion display screen illustrated in FIG. 4, when the user selects the reservation deletion button for the program 2-2 of CH2 with the input device 11 such as a remote controller, the microprocessor 7 receives the instruction and the nonvolatile selection button. Sex storage device 1
2 deletes the setting of the reservation of the program 2-2 of CH2, and sends the program 2-2 of CH2 from the screen display to the display control circuit 5.
And a screen display request signal for turning off the display of. When the user selects the end button shown on the display screen of FIG. 4 with the input device 11 such as a remote controller, the microprocessor 7 receives the instruction and supplies the display control circuit 5 with a screen deletion request signal of the deletion display screen. On the display device 14, only the video of the program 1-2 continues to be displayed. Thereafter, even at pm8: 30, the reservation setting has already been erased from the nonvolatile storage device 12, so the reservation of the program 2-2 of CH2 is not started, and the user continues to watch the program 1-2. be able to.
Then, at 9:00 pm, the program 3-3 on CH3
Is started by a normal reservation start process.

In a case where the initial setting is such that notification is made using an indicator (see FIG. 3), the microprocessor 7 receiving the duplicate detection signal from the comparison circuit 9
The indicator 13 is turned on for a few seconds. At this time, the display control circuit 5 is not particularly instructed, and there is no need to make a selection as shown in FIG. Therefore, when the user does not perform any operation, the reservation of the program 2-2 of CH2 and the reservation of the program 3-3 of CH3 are executed together. It is possible for the user to delete the reservation by turning on the indicator as before. As described above, an example in which the same channel CH1 is continuously viewed and the program is started by switching the program has been described. However, since there is a change in the information of the program being viewed even when the channel is selected, the same processing procedure is used in this case. Is started.
