Abstract

PURPOSE:To record all high definition television broadcast information during absence even when a broadcast schedule time is put off. CONSTITUTION:A controller 2 gives a reservation data including a data representing a video recording start time, a video recording end time and a reserved program to be a high definition television broadcast program entered by an entry device 1 to a storage device 3, in which the data is stored. A comparator 4 receives a discrimination data representing it that a high definition television broadcast is received from a MUSE/NTSC converter 8 and permits the start of video recording based on the discrimination signal after the arrival to a video recording start time. Thus, the controller 2 commands the start of video recording to a video recording device from the start of the high definition television broadcast. The end of the video recording is commanded based on the discrimination data even after the arrival to the video recording end time.

Description

[Detailed description of the invention]

2. Description of the Related Art Currently, NTSC television broadcasting is being carried out in Japan, and large-screen, high-definition, high-definition television broadcasting is about to begin. In this high-definition television broadcasting, MUSE (Multiple Sub-N
yquist Sampling Encoding)
The system has been developed and it is now possible to broadcast via satellite. In order to receive a high-definition television broadcast signal (MUSE signal), a satellite broadcast reception tuner, a MUSE decoder, and a high-definition television broadcast monitor are required. However, considering the prevalence of NTSC television receivers, it is necessary to adopt a down converter that converts MUSE signals to NTSC signals so that high-definition television broadcasts can be received on NTSC television receivers. It is thought that such systems will become common in the future.

[0003] Recently, video tape recorders and the like incorporating these MUSE/NTSC converters and satellite broadcast reception tuners have been developed. Conventionally, in video tape recorders, a timer reservation function for television broadcasting has been essential, and by making timer reservations,
It is now possible to automatically record multiple desired programs at a predetermined time slot.

[0004] FIG. 3 is a flowchart illustrating recording of an absentee recording by such a conventional absentee recording device. Conventional absentee recording devices are equipped with a storage device for registering reservation data, and can store reservation data such as the recording channel, date (day of the week), recording start time and end time, channel, etc. set by the user using an input device. It is designed to be remembered. The control device determines the start and end of recording by comparing the data in the storage device and the data in the clock device, and controls the channel selection device to record the reserved program.

That is, the control device performs step S in FIG.
When the start of recording is determined based on the data in the storage device and the data in the clock device in step 1, the power is turned on in the next step S3 to receive broadcasts (step S4), and the channel selection device is controlled in step S5 to start recording. start. If the recording start time has not yet arrived, the process waits in step S2. Based on the data from the clock device, the control device causes the recording to continue in step S7 until the recording end time is reached, and when it is determined in step S6 that the recording end time has come, stops the recording in the next step S8, Next, in step S9, the power is turned off and the process ends.

By the way, in television broadcasting,
The scheduled broadcast time may be postponed. For example, if a baseball broadcast is extended, the broadcast times of subsequent programs will be delayed by about 30 minutes or an hour. Other special programs may also be broadcast, and the scheduled broadcast time is postponed relatively frequently.

[0007] However, in recording while the user is away, even if the scheduled broadcast time of a reserved program is changed, it is rarely possible to reset the start time and end time of the reservation in accordance with this change. Therefore, if the scheduled broadcast time of the reserved program is postponed, the broadcast start time and end time of the reserved program will not match the recording start time and end time stored in the storage device, and the latter part of the reserved program will be recorded. There was a problem that it was not done.

[0008]

SUMMARY OF THE INVENTION As described above, the above-mentioned conventional absentee recording device has a problem in that when the scheduled broadcast time is postponed, the latter part of the reserved program is not recorded.

The present invention has been made in view of this problem, and provides a video recording device that can reliably record a desired high-definition television broadcast program even when the scheduled broadcast time is postponed. The purpose is to provide.

[Configuration of the invention]

[Means for Solving the Problems] An absentee recording device according to the present invention stores reservation data including a recording start time, a recording end time, and data indicating whether a program to be recorded while absent is a high-definition television broadcast program. a storage device for storing information, a receiving means for outputting determination data indicating that the high-definition television broadcast is receivable and is being received, and a television signal received by the receiving means is recorded. and when the reservation data indicates that a high-definition television broadcast program is to be recorded while the user is away, the recording device records the recording device based on the discrimination data at a time other than the recording start time and the recording end time reserved by the user. The recording apparatus includes a control means for instructing the recording device to start and end recording.

[0011]

In the present invention, in addition to the recording start time and recording end time, the storage device also stores data indicating whether the program to be recorded while the user is away is a high-definition television broadcast program. When the recording start time arrives, if the reservation data indicates that the high-definition television broadcast program is to be recorded while the user is away, the control means determines whether the high-definition television broadcast is being received based on the determination data from the reception means. When it is determined whether or not the high-quality television broadcast is received and the reception of the high-definition television broadcast is started, the recording device is instructed to start recording the television broadcast. When the recording end time comes, the control means determines whether or not the high-definition television broadcasting has ended based on the determination data. If it has not finished, the recording device is instructed to continue recording. As a result, even if the broadcast time of high-definition television broadcasting is postponed, all reserved programs are recorded.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of an absent recording device according to the present invention.

[0013] A MUSE signal induced in a parabolic antenna for satellite broadcast reception (not shown) is tuned to a predetermined channel by a satellite broadcast reception tuner (not shown), and the MUSE signal is sent to the MU
SE/NTSC converter 8. MUSE/
The NTSC converter 8 converts the MUSE signal into an NTSC signal and outputs it to the channel selection device 7. The channel selection device 7 also receives an NTSC signal induced by an antenna (not shown). The channel selection device 7 selects a predetermined channel of the NTSC signal and outputs it to the recording device 5. Note that, when receiving high-definition television broadcasting, the MUSE/NTSC converter 8 outputs discrimination data indicating that the high-definition television broadcasting is being received.

On the other hand, the input device 1 has operation keys (not shown), and outputs data to the control device 2 based on the user's key operations. Using this input device 1, the user specifies the absentee recording mode, sets the recording channel, start time, end time, and whether or not the reserved program is a high-definition television broadcast. The control device 2 controls each part based on data from the input device 1. When reservation data such as the recording channel, start and end time, and whether or not the reserved program is a high-definition television broadcast is input through the input device 1, the control device 2 stores these reservation data in the storage device 3. . The recording device 5 is controlled by the control device 2 to record the NTSC signal from the channel selection device 7. The clock device 6 outputs current date and time data. These clock device 6 and channel selection device 7 are also standard equipment in conventional VTRs.

The comparison device 4 is controlled by the control device 2 and compares the reservation data stored in the storage device 3 with the clock device 6.
The current date and time data from the MUSE/NTSC converter 8 are compared with the discrimination data from the MUSE/NTSC converter 8. That is,
If the reservation start date and start time data of the reservation data stored in the storage device 3 match the current date and time data from the clock device 6, the comparison device 4 determines that the recording start time has been reached. The control device 2 provides data indicating that the reserved program is a high-definition television broadcast program, and also issues a recording permission signal based on the reservation data indicating whether the reserved program is a high-definition television broadcast program and the determination data from the MUSE/NTSC converter 8. It is designed to be output to the control device 2. Furthermore, if the reservation end date and end time data of the reservation data stored in the storage device 3 match the current date and time data from the clock device 6, the comparison device 4 determines the recording end time. Data indicating that the recording permission signal has been reached is given to the control device 2, and when the output of the determination data from the MUSE/NTSC converter 8 is stopped, the output of the recording permission signal is stopped.

When the control device 2 is given data indicating that the recording start time has arrived, it turns on the power to the recording device 5, and while the recording permission signal is being input, the recording device 5 selects a channel from the channel selection device 7. It is designed to record NTSC signals.

Next, the operation of the absent recording device configured as described above will be explained with reference to the flowchart shown in FIG.

Now, it is assumed that the input device 1 is used to specify that a predetermined high-definition television broadcast program be recorded from the start to the end. Reservation data such as the recording channel, recording start time, and recording end time inputted from the input device 1 is stored in the storage device 3 by the control device 2 . Here, it is assumed that the broadcast time of the reserved high-definition television broadcast program is postponed by 30 minutes.

In step S11 of FIG. 2, the comparison device 4 determines whether the recording start time has been reached based on the reservation data indicating the recording start time in the storage device 3 and the data from the clock device 6. If the recording start time set by the user has not yet arrived, the process waits in step S12. When the recording start time arrives, the comparison device 4 outputs data indicating that the recording start time has arrived to the control device 2. Then, the control device 2 turns on the power in step S13, and receives the broadcast in step S14.

The comparator 4 determines the broadcasting system in step S15. That is, the discrimination data is output from the MUSE/NTSC converter 8, and the comparison device 4
compares the reservation data from the storage device 3 and the discrimination data from the MUSE/NTSC converter 8. The reservation data indicates that recording of a high-definition television broadcast program has been specified, and as mentioned above, the broadcast time has been postponed by 30 minutes, and high-definition television broadcasting is not being performed at this time. , the control device 2 executes the process in step S1.
7 to put recording on standby. In this case,
The NTSC signal induced in the antenna is input to the channel selection device 7, and the channel selection device 7 selects a predetermined channel of the NTSC signal and outputs it to the recording device 5.

30 minutes from the recording start time set by the user
After the minute has elapsed, high-definition television broadcasting begins. Then, the MUSE/NTSC converter 8
The SE signal is converted into an NTSC signal and provided to the channel selection device 7, and discrimination data indicating that high-definition television broadcasting has started is provided to the comparison device 4. The comparison device 4 gives a recording permission signal to the control device 2 based on this discrimination data,
The control device 2 instructs the recording device 5 to start recording in step S18. Thereby, the high-definition television broadcast program reserved by the user is recorded by the recording device 5 from the beginning.

In step S19, the comparator 4 determines whether the recording end time has been reached based on the reservation data and the data from the clock device 6. If the recording end time has not yet been reached, the control device 2 continues recording in step S20. When it is detected from the data from the clock device 6 that the recording end time has been reached, the comparison device 4 determines the broadcasting method in step S21. At this point, there are 30 minutes left until the high-definition television broadcast ends, and MUSE
/NTSC converter 8 outputs discrimination data indicating that high-definition television broadcasting is being received. The comparison device 4 continuously outputs a recording permission signal to the control device 2 based on this discrimination data. Thereby, the control device 2 causes the recording device 5 to continue recording in step S23.

30 minutes from the recording end time set by the user
When the high-definition television broadcast ends after a minute, the comparator 2 determines that the high-definition television broadcast has ended by stopping the output of the determination data from the MUSE/NTSC converter 8, and sends data to stop recording. Output to control device 2. As a result, the control device 2 controls the recording device 5 to end recording in step S24, and turns off the power in step S25 to end the process.

As described above, in this embodiment, in addition to determining whether the recording start time and recording end time set by the user have been reached, the comparator 4 determines whether or not it is a high-definition television broadcast. The start and end of recording is determined based on discrimination data indicating whether or not the program is being broadcast, and even if the broadcast time of a high-definition broadcast program is postponed, the entire program can be recorded while the user is away.

[0025]

As described above, according to the present invention, even if the scheduled broadcast time is postponed, a desired high-definition television broadcast program can be reliably recorded while the user is away.
