Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a broadcast signal receiving apparatus according to the present invention. In this embodiment, a tuner device 1 for receiving a broadcast signal and decoding a video / audio signal and electronic program guide data contained therein, an input device 2 such as a remote controller, and a clock for obtaining time 3 and a program table storage unit 4 for storing an electronic program table
And a threshold value storage unit 5 for storing numerical values for controlling the operation of the apparatus, a program name storage unit 6 for storing a name of a program to be viewed, and a reserved program storage unit for storing information on viewing reservation. 7
And a control device 8 for processing each information and program-controlling the tuner device 1.

Next, the operation of this embodiment will be described with reference to the block diagram of the program information record in FIG. 2 and the block diagram of the entire electronic program guide in FIG. Viewers (users)
The threshold value a and the threshold value b for designating the operation of the present apparatus are input from the input device 2 and stored in the threshold value storage unit 5 in advance. The threshold value a is a value that is compared with the elapsed time from the start of the program. Based on the comparison result of the present apparatus, it is determined whether to continue viewing the channel or switch to another channel. . The threshold value b is a value that is compared with the waiting time until the start of the next program. Based on the comparison result, the apparatus continues or stops the viewing of the program and stops watching the next broadcast program. Decide whether to make a reservation.

The tuner device 1 receives a broadcast signal and extracts a video / audio signal and electronic program guide data. Video /
The audio signal is sent to a television receiver (not shown), and the electronic program guide data is supplied to and stored in the program guide storage unit 4. The electronic program guide is a set of records (program information records) having program information. As shown in FIG. 2, the program information record includes a program name field 11 for storing a unique program name across all channels for identifying a program, a start time field 12 for storing a start time of the program, and an end time. End time field 13 for storing
including.

As shown in FIG. 3, the entire electronic program guide is composed of program information records belonging to the same channel to form a channel program table, and the channel program table is composed to constitute a program table of the entire broadcast. The program information records are arranged in the order in which they are broadcast in the channel program table.

A viewer uses the input device 2 in FIG. 1 to select a channel on which a program to be viewed is being broadcast. Information on which channel has been selected is supplied from the input device 2 to the control device 8. If the broadcast signal contains information on the current time, that information may be used.

The control unit 8 searches the program table of the entire broadcast stored in the program table storage unit 4 for a program table of the channel selected by the viewer. First, the start time and the end time of the program are read from the first program information record constituting the program table of the selected channel, and are compared with the current time. If the current time is not between the start time and the end time of the program, the same processing is performed for the next program information record, and a program information record whose current time is between the start time and the end time of the program is obtained. Repeat until found. If such a program information record is found, that program information record is the information record of the program that the viewer is trying to view.

The control device 8 stores the program name read from the program name field of the program information record found in this manner in the program name storage section 6. Subsequently, the control device 8
Calculates the difference between the program start time read from the program start time field of the program information record and the current time, obtains the elapsed time from the start time of the program, and stores it in the threshold storage unit 4. Is compared with the threshold value a.

When the calculated elapsed time from the start of the program is less than or equal to the threshold value a, it is assumed that the time has not passed much since the start of the program and the beginning of the program that could not be viewed is negligible. As a result, the viewer does not perform any operation on the channel and continues to view the channel. On the other hand, when the calculated elapsed time from the start of the program is larger than the threshold value a, in this embodiment, the following procedure is performed so that the viewer can view the same program being broadcast on another channel. Make changes.

First, the control device 8 determines that the content of the program name field is the same as the program name stored in the program name storage unit 6 and that the program start time is the same as or earlier than the current time, and On the condition that the difference between the program start time and the current time is equal to or smaller than the threshold value a, the program information record of the program table of the channel is searched. If there is no corresponding program information record, a similar search is performed on the program table of the next channel, and the process is repeated until a program information record satisfying the condition is found. When a program information record satisfying the condition is found, the control device 8 operates the tuner device 1 to receive the channel to which the program information record belongs.

When a program information record satisfying the above conditions is not found, this apparatus performs the following procedure.
Channel operation is performed so that the viewer can view the next broadcast of the program having the same content. That is, the control device 8 determines that the content of the program name field is the same as the program name stored in the program name storage unit 6, the program start time is later than the current time, and the program start time and the current time are different. On the condition that the difference is equal to or smaller than the threshold value b, a program information record in the program table of the channel is searched. If there is no corresponding program information record, a similar search is performed on the program table of the next channel, and the process is repeated until a program information record satisfying the condition is found. When a program information record satisfying the condition is found, the control device 8 operates the tuner device 1 to receive the channel to which the program information record belongs.

When a program information record satisfying the above conditions is not found, this apparatus performs the following procedure.
A viewing reservation operation is performed so that the viewer can view the next broadcast of the program with the same content. That is, the control device 8 sets the program list of the channel under the condition that the content of the program name field is the same as the program name stored in the program name storage unit 6 and the program start time is later than the current time. Search for the program information record. If there is no corresponding program information record,
A similar search is performed on the program table of the next channel, and the search is repeated until a program information record satisfying the condition is found. When the first program information record that satisfies the condition is found, the control device 8 stores the channel number to which the found program information record belongs and the start time of the program in the reserved program storage unit 7.

The search is continued by changing the program table of the target channel. Thereafter, each time a program information record that satisfies the condition is found, the program start time is stored in the reserved program storage unit 7.
Is compared with the program start time stored in. If the program start time is earlier than the program start time stored in the reserved program storage section 7, the channel number and the program start time stored in the reserved program storage section 7 are deleted, and a new channel number is set. The program start time is stored in the reserved program storage unit 7.

The above processing is performed for all channels, and the next program start time closest to the current time and its broadcast channel are stored in the reserved program storage unit 7. The control device 8 sends the channel stored in the reserved program storage unit 7 to the tuner device 1 in the same manner.
The reception reservation is made so that the program is received at the program start time stored in the program.

As described above, according to this embodiment, the elapsed time from the start time of the program desired to be viewed is compared with threshold value a, and when the elapsed time is larger than threshold value a, the same value is set. A program information record is searched on the condition that the program name is the same as or earlier than the current time and the difference between the program start time and the current time is equal to or smaller than the threshold a. When the program information record is found, the tuner device 1 is tuned to another channel to which the program information record belongs. When the program information record with the above condition is not found, the same program name and the program start time are set. If the program information record of the program table of the channel is found after the current time and on the condition that the difference between the program start time and the current time is equal to or less than the threshold value b, the program information record is found. Field of de, is tuned to another channel in the tuner device 1. Therefore, according to this embodiment, the viewer only needs to perform a channel selection operation on one channel broadcasting the program desired to be viewed, and the program start time on that channel has passed. But
Without performing a channel selection operation, the same program as the program desired to be viewed on another channel can be automatically selected and immediately viewed from a time position less than the time of the threshold a from the beginning. it can.

When the program start time on the channel on which the channel selection operation has been performed has passed, and when the same program as the program desired to be viewed is not started to be broadcast on another channel, in this embodiment, The next program start time closest to the current time of the program having the same content as the program desired to be viewed and its broadcast channel are stored in the reserved program storage unit 7, and the tuner device 1
, The viewer can view a desired program from the beginning after a certain time without performing a reservation operation.

Next, another embodiment of the present invention will be described. In the above embodiment, when there is no channel that can be viewed immediately, the reservation is automatically made according to the next program start time closest to the current time, but in this embodiment, the earliest next program start time is set. Instead of automatically making a reservation in accordance with the schedule, a program guide relating to a target program and a channel for broadcasting the target program is displayed, and the viewer can specify a broadcast at a convenient time.

That is, the control device 8 in FIG. 1 determines that the content of the program name field is the same as the program name stored in the program name storage unit 6 and that the program start time in the program start time field is Provided that it is later than the current time,
Search the program information record of the channel's program table. If there is no corresponding program information record, a similar search is performed on the program table of the next channel, and the process is repeated until a program information record satisfying the condition is found. When a program information record satisfying the condition is found, the control unit 8
Stores in the reserved program storage section 7 the channel number to which the found program information record belongs and the start time of the program.

The search is continued by changing the program table of the target channel. Thereafter, each time a program information record that satisfies the condition is found, the program start time is stored in the reserved program storage unit 7.
To be added. The above processing is performed for all the channels, and the broadcast channel and the broadcast start time are stored in the reserved program storage unit 7 for all the program information records satisfying the conditions. The control device 8 includes the reserved program storage unit 7
Is displayed to the viewer, and the user is allowed to select which channel the broadcast is to be received from, and the broadcast is received by the viewer using the input device 2 on the selected channel and the program start time. The reception reservation is made to the tuner device 1 so as to allow the tuner device 1 to perform reception.

Next, an embodiment of the present invention will be described. FIG. 4 shows the first channel ch. 1 and the second channel ch. 2
2 shows a program schedule table in the case where the same program “MOVIE1” of 2 hours is broadcasted with a 30-minute delay. ch.
The program start time at 1 is 12:00 for the first time, and the same program is repeated every two hours thereafter. ch. The program start time at 2 is 12:30 for the first time, and the same program is repeated every two hours thereafter. ch. The program start time at 3 is 13:00 at the first time, and the same program is repeated every two hours thereafter.

The viewer searches for another channel if more than 10 minutes have passed since the start of the program at the time of channel selection, and reserves the next program if there is no start of the next program within 10 minutes. The viewer inputs in advance 10 minutes as the threshold value a and 10 minutes as the threshold value b for designating the operation of the present apparatus from the input device 2, and stores them in the threshold value storage unit 5.
Further, the received electronic program guide is stored in the program guide storage unit 4.

In this state, at time t1 shown in FIG.
(= 12: 05), the viewer uses the input device 2 to set c

The calculated elapsed time is 5 minutes, but does not exceed the threshold value a of 10 minutes. Therefore, the present apparatus does not perform the channel operation, and the viewer selects the channel ch. 1 to continue watching the program "MOVIE1".

On the other hand, at time t2 (= 12
At 35 minutes), the viewer uses the input device 2 to select ch. It is assumed that 1 is selected. Then, the control device 8 sets the electronic program guide in the program guide storage unit 4, the channel number (ch.1 in this case) input from the input device 2, and the current time (12:00 in this case) sent from the clock 3. 35 minutes), and ch.
1 (here, "MOV")
IE1 ″) is acquired, and the program name is stored in the program name storage unit 6, and the elapsed time from the start of the program is calculated.

In this case, since the program has elapsed 35 minutes from the start and exceeds the threshold a of 10 minutes, the control device 8 searches the electronic program guide for another channel for broadcasting this program. Then, as can be seen from FIG.
As of 5 minutes, ch. 2, the same program is being broadcast, and the elapsed time from the start of the program is 5 minutes. Since this elapsed time does not exceed the threshold value a of 10 minutes, the control device 8 operates the tuner device 1 and sets the ch. Select 2

At time t3 (= 12: 25) shown in FIG.
Minutes), the viewer is ch. It is assumed that 1 is selected. Since the program has elapsed 25 minutes from the start and has exceeded the threshold value a of 10 minutes, the control device 8 searches the electronic program guide for another channel that broadcasts this program. Then, FIG.
As can be seen from 5 minutes later, at 12:30, ch. 2, the same program is scheduled to be broadcast. Since the waiting time of 5 minutes does not exceed the threshold value b of 10 minutes, the control device 8 operates the tuner device 1 and sets the ch. Select 2

At time t4 (= 12: 45) shown in FIG.
Minutes), the viewer is ch. It is assumed that 1 is selected. Since the program has elapsed 45 minutes from the start and exceeds the threshold a of 10 minutes, the control device 8 searches the electronic program guide for another channel that broadcasts the program. Then, FIG.
As can be seen from ch. 2 and 1 from the start of the same program
Five minutes have elapsed, which also exceeds the threshold a of 10 minutes. On the other hand, as shown in FIG. In three, 15
The same program is scheduled to start at 13:00 minutes later, but the waiting time of 15 minutes exceeds the threshold value b of 10 minutes.

Accordingly, in this case, the control device 8 determines that there is no channel that can be viewed from the current time,
The next program start time closest to 5 minutes is ch. 3 at 13:00, the tuner device 1 is operated, and ch. 3

In the same manner as in the above embodiment, the viewer searches another channel if more than 10 minutes have passed since the start of the program at the time of selecting a channel, and if there is no next program start within 10 minutes, the next channel is searched. The viewer inputs 10 minutes as the threshold value a and 10 minutes as the threshold value b from the input device 2 for designating the operation of the apparatus in advance so as to make a reservation for the program of 5 is stored. Further, the received electronic program guide is stored in the program guide storage unit 4.

In this case, at time t5 (= 12: 45) in FIG.
Minutes) and the viewer is ch. Assuming that 1 is selected, c
h. 1 and ch. 2, the elapsed time from the start of the program exceeds the threshold a, and the earliest start of the next program is c
h. Since the start time is 14:00, the waiting time is 75 minutes and exceeds the threshold value b of 10 minutes, so the control device 8 performs a reservation process of the tuner device 1.

In this embodiment, at the time of the above-mentioned reservation processing, the control device 8 displays a program table from now on, and displays the ch. 1 as the first candidate c1, 14
30 minutes ch. 2 is set to the second candidate c2, 1
6:00 ch. 1 as the third candidate c3,
16:30 ch. The second program start time is set to the fourth candidate c4.
So that the viewer can select either of them. The viewer selects one convenient candidate from these candidates c1 to c4. The control device 8 performs a reservation process on the tuner device 1 so as to receive the broadcast on the channel indicated by the selected one candidate and the program start time.
