Abstract

PURPOSE:To implement automatic answering video recording in a desired screen mode for each high definition television broadcast program. CONSTITUTION:A controller 2 gives a reservation data including a data representing a video recording start time, a video recording end time and a data of a screen mode entered by an entry device 1 to a storage device 3, in which the data is stored. A comparator 4 discriminates the video recording start time and the video recording end time by a clock device 6. When the arrival of the video recording start time is indicated by an output of the comparator 4, the controller 2 commands the screen mode set by the user to a MUSE/ NTSC converter 8, in which the MUSE signal is converted into the NTSC signal in the set screen mode. The video recording time is commanded by the controller 2 to record the signal from the MUSE/NTSC converter 8. Thus, the automatic answering video recording is attained in the screen mode different from each program.

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] Incidentally, the aspect ratio of the screen of the high-definition television broadcasting system is different from that of the screen of the current NTSC system. Due to the difference in the screen aspect ratio of these systems, high-definition television broadcasting is based on NTSC.
Some MUSE/NTSC converters have three types of screen modes.

FIG. 3 is an explanatory diagram for explaining the screen mode of the MUSE/NTSC converter. 3(a) shows the zoom mode, FIG. 3(b) shows the squeeze mode, and FIG. 3(c) shows the wide mode.

In the zoom mode, only the data in the center of the screen of the MUSE signal is written to a memory in which writing and reading are asynchronous. Data is read from this memory using a read clock based on the scanning frequency of the NTSC system. As a result, as shown in FIG. 3(a), only the central part of the screen of the wide aspect ratio image (the broken line portion) is displayed on the screen with the aspect ratio of 4:3. In the squeeze mode, all image data of the MUSE signal is written into the memory. Data is read from memory using a read clock with a higher frequency than in zoom mode. As a result, a high-definition television image with a wide aspect ratio is
It is displayed as a TSC image. That is, in this case, the image is collapsed in the horizontal direction as shown in FIG. 3(b), and becomes a vertically elongated image on the screen. In wide mode, the squeeze mode image is compressed vertically and converted to the original wide aspect ratio image. That is, by reducing the number of scanning lines using a vertical filter, an image with a wide aspect ratio is displayed within a screen with an aspect ratio of 4:3, as shown in FIG. 3(c). In this case, a predetermined black level is displayed at the top and bottom of the screen.

[0006]Recently, video tape recorders and the like have been developed which incorporate such a MUSE/NTSC converter and a satellite broadcast reception tuner and are capable of recording high-definition television broadcasts. By the way, in conventional video tape recorders, a timer reservation function for television broadcasting has been essential, and by making a timer reservation,
It is now possible to automatically record multiple desired programs at a predetermined time slot.

[0007] Such a conventional absent recording device is equipped with a storage device for registering reservation data.
Recording channel set by user by input device,
Reservation data such as the date (day of the week), recording start time and end time, and channel are stored. The control device determines the start and end of recording by comparing data in the storage device and data in the clock device, and instructs the recording device to record the reserved program received by the channel selection device. There is.

[0008] When recording high-definition television broadcasts using such a conventional recording device, MUSE/
The NTSC signal from the NTSC converter is given to the recording device. Even in this case, recording while the user is away is possible by controlling the recording start and end times of the recording device based on the reservation data.

By the way, as mentioned above, MUSE/N
When displaying the video signal from the TSC converter,
There are three types of screen modes. When performing normal recording, a desired program can be recorded in a desired screen mode by changing the settings of the MUSE/NTSC converter. However, when recording while the user is away, the screen mode of the reserved program to be recorded is fixed to the last set mode. That is, when reserving a plurality of programs, there is a problem in that it is not possible to record each program while the user is away in a different screen mode.

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.

[0015] 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 transmitted 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 the MUSE/NTSC converter 8 is capable of outputting NTSC signals in three types of screen modes: zoom mode, wide mode, and squeeze mode.

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, and sets the recording channel, start time, end time, and screen mode when recording a high-definition television broadcast program. The control device 2 controls each part based on data from the input device 1. When reservation data such as a recording channel, start and end time, and screen mode for recording a high-definition television program are 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 and receives the N from the channel selection device 7.
It is designed to record TSC signals. 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.
Compare the current date and time data from . 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. Data indicating this is provided 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 the arrival is given to the control device 2.

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 instructs the recording device 5 to record the NTSC signal from the channel selection device 7. Furthermore, in this embodiment, the control device 2
M generates a control signal for setting the screen mode of the MUSE/NTSC converter 8 based on the data indicating the screen mode among the reservation data stored in the storage device 3.
The signal is output to the USE/NTSC converter 8. The MUSE/NTSC converter 8 is connected to the control device 2
Based on the control signal from the controller, the MUSE signal is converted into an NTSC signal of the screen mode set by the reservation data and output. Further, when the control device 2 is given data indicating that the recording end time has been reached, the control device 2 stops recording the recording device 5 and turns off the power.

Next, the operation of the absent recording device configured as described above will be explained with reference to FIG. FIG. 2 is an explanatory diagram showing the procedure for setting recording when the user is away.

Now, using the input device 1, a predetermined high-definition television broadcast program is designated to be recorded while you are away (
Suppose that the user makes a reservation (A reservation) and then specifies recording of another high-definition television broadcast program in wide mode while the user is away (reservation B). In this case, as shown in FIG.
First, set the day of the week as a reservation, then set the recording start time,
Set the recording end time, channel, and screen mode in sequence. In this case, zoom mode is specified as the screen mode. When the A reservation is completed in this way, the B reservation is then set. That is, first, the day of the week is set, and then the start time, end time, channel, and screen mode are set in sequence. In B reservation, wide mode is specified as the screen mode. In this way, it is possible to set different screen modes for A reservation and B reservation.

Reservation data such as the recording channel, recording start time, recording end time, screen mode, etc. input from the input device 1 is stored in the storage device 3 by the control device 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. The power is off and the device is in standby mode until the recording start time set by the user is reached. When the recording start time of the A reservation comes, 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 and receives the broadcast. As a result, the MUSE signal induced in the antenna is input to the MUSE/NTSC converter 8 and received.

The control device 2 outputs a control signal specifying the zoom mode to the MUSE/NTSC converter 8 based on the reservation data of the A reservation stored in the storage device 3. The MUSE/NTSC converter 8 converts the MUSE signal into a zoom mode NTSC signal and supplies it to the channel selection device 7. The channel selection device 7 performs a channel selection operation and provides the recording device 5 with high-definition television broadcasting converted into an NTSC signal. On the other hand, the control device 2 instructs the recording device 5 to start recording based on the output of the comparison device 4, and the recording device 5 records a high-definition television broadcast program.

When the comparison device 4 detects from the output of the clock device 6 that the recording end time of the A reservation has been reached, it outputs a signal indicating the end of recording to the control device 2. Thereby, the control device 2 causes the recording device 5 to finish recording. In this way, A
High-definition television broadcast programs based on reservations can be recorded while you are away in zoom mode.

Next, when the recording start time of the B reservation is reached, the control device 2 turns on the power based on the output of the comparator 4 and causes the control device 2 to receive the broadcast. In this case, the wide mode is designated by the reservation data in the storage device 3, and the control device 2 designates the wide mode as the screen mode to the MUSE/NTSC converter 8. In this way, MUSE
/NTSC converter 8 converts the MUSE signal into a wide mode NTSC signal and outputs it. The recording device 5 is controlled by the control device 2 and records the B-reserved broadcast program until the recording end time. In this way, the high-definition television broadcast program reserved for B is recorded while the user is away in wide mode.

As described above, in this embodiment, in addition to the recording start time and the recording end time, the input device 1 allows M
Specify the screen mode of USE/NTSC converter 8,
The control device 2 controls the MUSE/NTSC converter 8 to convert the reserved program into an NTSC signal of the set screen mode, so that even when you are away from home, you can specify the desired screen mode for each program and record it. can be done.

[0026]

As described above, according to the present invention, it is possible to record a desired program in a desired screen mode when recording while the user is away.
