By the way, recently, the ratio of wide broadcasting has been increasing, and along with this, the number of televisions having wide screens compatible with wide broadcasting is rapidly increasing. In the normal screen, the horizontal to vertical ratio is 4: 3, whereas in the wide screen, this is 16: 9.

In wide broadcast, of the 263 scanning lines, the 22nd to 43rd scanning lines and the 240th to 262th scanning lines are not used. That is, the scanning lines used in wide broadcast are the 1st to 21st and the 44th to 239th. This is why the upper and lower parts of the screen are not used when receiving a wide broadcast on a normal screen television.

[0006] In such a broadcasting system, wide broadcasting is performed by a conventional recording device having a reserved recording mode of a program.
In the case of recording, the video signal is recorded even for the scanning lines that are not used in wide broadcast.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 is a block diagram of a recording device according to an embodiment of the present invention, FIG. 2 is a display image diagram when a program is reserved in the recording device, and FIG. 3 is a flowchart of a program processed by a microcomputer of the recording device. Is.

The recording apparatus according to the present embodiment is a digital recording apparatus incorporated in a VCR or a television with video, and has a program reservation recording mode. As shown in FIG. 1, the recording device 10 is
A tuner 11 for receiving a television broadcast, a separation circuit 12 for separating a video signal from a television signal received by the tuner 11, a magneto-optical disk 13 as a recording medium for recording the video signal, and the recording device are integrated. A microcomputer 14 for controlling the recording apparatus and an operation unit 15 for comprehensively operating the recording apparatus.

The microcomputer 14 has a well-known configuration in which the CPU performs arithmetic processing while exchanging signals with the RAM in accordance with the procedure stored in the ROM. Further, the operation unit 15 is provided in the remote controller. Then, the microcomputer 14 comprises a reservation section for making a program reservation and a recording execution section for making a recording of the reserved program, and the respective functions are as follows.

First, the function of the reservation section will be described with reference to FIG.

When the program reservation recording mode is selected by operating the operation unit 15, the information is sent to the microcomputer 14. As a result, the menu screen as shown in FIG. 2 is displayed on the television 20 connected to the recording device 10. The user operates the operation unit 15 while watching this screen to make a program reservation.

That is, here, as reservation items, a reservation date (DATE) and a reservation start time (START TIM)
E), reservation end time (END TIME), channel (CHANNEL), and screen format (VIDEO) are prepared. In the screen format (VIDEO), the wide screen (WIDE) or the normal screen (NORMAL) is selected by 1 or 2. In FIG. 2, the wide screen (WIDE) is selected.

By operating the operation unit 15, the reservation date (DAT
E), reservation start time (START TIME), reservation end time (END TIME) and channel (CHAN)
NEL) is set, and a wide screen (WIDE) or normal screen (NORMAL) is set in the screen format (VIDEO) item.
If you select, the setting data will be
Is entered and the program reservation is completed.

Next, the function of the recording execution unit will be described with reference to FIG.

When the reservation start time arrives on the reservation day, the tuner 11 is activated to receive the television broadcast of the set channel. The received signal is sent to the separation circuit 12 and the video signal is separated. The separated video signal is sent to the microcomputer 14.

At this time, the microcomputer 14
First, it is determined whether the screen setting of the reserved program is the wide screen or the normal screen (S1 in FIG. 3). When the normal screen is set, video signals are captured one screen at a time and the video signals of each screen are sequentially recorded on the magneto-optical disk 13 for all scanning lines (S2, 3).

When the wide screen is set, the video signals are fetched one screen at a time, but the scanning lines are selected after the video signals of each screen are fetched (S4, 5). That is, after the video signals corresponding to 262 scanning lines of one screen are fetched in step 4, the video signals of the 22nd to 43rd scanning lines and 241st to 262th scanning lines are fetched in step 5.
It is determined whether or not it corresponds to the scanning lines up to the th.

When it is determined that the video signal corresponds to these scanning lines, the process returns to step 5. On the other hand, when it is determined that the video signal does not correspond to these scanning lines, the process proceeds to step 6 and the video signal is recorded on the magneto-optical disk 13.

As a result, the 1st to 21st scanning lines used in wide broadcast and the 44th to 240th scanning lines are used.
Video signals are selectively recorded on the magneto-optical disk 13 only for the scanning lines up to the th. As a result, compared with the case where the video signal is recorded on the magneto-optical disk 13 for all the scanning lines, the recorded information amount is about 18.
Compressed by 7%. Therefore, the capacity of the magneto-optical disk 13 can be reduced.

Since the unrecorded scanning line is not used in wide broadcast, even if it is not recorded, no trouble occurs in recording and reproducing the broadcast.

Further, the video signal recorded on the magneto-optical disk 13 is known to have a wide screen depending on its recording condition. Therefore, when the reserved program is reproduced, the user selects the screen format. Even without it, the program can be played on a wide screen.

Although the magneto-optical disk is used as the recording medium for recording the video signal in the above embodiment, the present invention is not limited to this, and a hard disk, a memory IC, a magnetic tape or the like can be used. Is.

Further, although the above-described embodiment applies the present invention to a digital type recording apparatus, it can also be applied to an analog type recording apparatus. In an analog type recording device, the captured video signal is directly recorded on the magnetic tape that is the recording medium, so the meaning of compressing and recording the video signal is small, but from the recording situation, Since it is possible to determine the screen of the program that has been reserved and recorded, it is not necessary to set the screen format when the program is reproduced.

[0028]

As described above, in the case of the recording apparatus according to the present invention and the recording medium used for the same, it is possible to select a normal screen or a wide screen as a reservation item when making a program reservation, and the reservation is made. When recording a program, if the program is set to wide screen, the video signal is recorded except for the part of the scan line that is not used in wide broadcast, so when the recording device is a digital system. Makes it possible to reduce the capacity of the video signal recording medium.
Also, regardless of whether it is an analog system or a digital system, the screen format of the recorded program can be known.
The user does not have to select the screen when playing the program.
