Abstract

PURPOSE:To enable a program longer than a recordable time by a single recording medium to be recorded by turning ON/OFF the power source of a tuner independently in a recording and reproducing device incorporating a timer reservation function and plural kinds of tuners. CONSTITUTION:In a VTR 10, a power source switch Sw1 is set as the one dedicated for a BS tuner, and a power source switch Sw4 dedicated for a ground broadcast tuner 5, and they are controlled by a timer CPU 16 independently, respectively. And as an output terminal, the output terminals Out 2 and Out 3 other than Out 1 are provided. Furthermore, when the reservation of time exceeding the recording residual time of a magnetic tape in the VTR 10 is set at the time of performing recording by timer reservation, the timer CPU 16 is comprised so that no switches Sw1 and Sw2 are opened even after a recording operation on the tape is completed. In such a way, since tuner output is issued from the output terminal Out 2 even after the tape is fully recorded, the recording can be performed by connecting a VTR 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording/reproducing apparatus, and more particularly to a recording/reproducing apparatus incorporating a timer reservation function and a plurality of types of tuners (VHF, 014F, BS, etc.).

[Prior art and problems to be solved by the invention] Recording and reproducing devices are classified into several types depending on the recording and reproducing method and the type of recording medium used. The VTR (VTR), which uses magnetic tape to record and play back both video and audio signals, has been put into practical use.
Therefore, in the following explanation, the VTR will be used as an example.

A conventional VTR will be explained with reference to FIG.

FIG. 3 is a block diagram showing the main mechanisms of a conventional VTRI. As shown in the diagram, a monitor device 2 such as a CRT is connected. BS (satellite broadcasting) tuner 4. For terrestrial broadcasting (VH
F, Kano [) Tuner 5, CPU (central processing circuit)
6. Recording system (recording signal processing circuit)7. It is composed of a reproduction system (recording signal processing circuit) 8. In addition, Swl is a power ON/OFF switch, 3w2 is a selection switch for switching between the BS tuner 4 and the terrestrial broadcasting tuner 5, and Sw3
is recording system 7. Selection switch for switching playback system 8, (h+
is the video (audio) signal output terminal of the VTRI.

The above is an electrical configuration, and it goes without saying that it also includes mechanical configurations such as a recording/playback tape cassette loading mechanism and a magnetic tape loading mechanism, but these are not directly related to the gist of the present invention. , illustration and description thereof will be omitted.

The CPU 6 mainly functions when recording timer reservations, detecting the arrival of the reservation time using the built-in clock, and turning on/off the switches Swl and 8w2.

Performs operations such as switching. Specifically, according to the flowchart in Figure 4, timer recording of satellite broadcasting, etc. is performed, and when the timer scheduled recording is completed, tape running is stopped and switch S + (VTR main power supply and BS tuner power supply ), and the so-called answering video recording of the video signal (or late-night program recording during sleep) is completed.

Note that if the magnetic tape is used up before the reservation setting time expires, the CPU 6 is configured to end the recording operation at that point, store the magnetic tape in the tape cassette, eject it from the main body of the device, and then turn off the power. It is configured.

By the way, the magnetic tape used in the VTRI having such a configuration has a finite recording time, which is less than three hours at most. Therefore, if the 3x mode is used, it is possible to record long programs of more than 8 hours, but on the other hand, there is a drawback that the image quality tends to deteriorate. In addition, it is impossible to perform timer recording for a longer time than the recordable time of the magnetic tape being used, such as when continuously timer recording a long program longer than 8 hours or multiple programs, and There was a drawback that recording was interrupted.

[Means to solve the problem]

The recording and reproducing device of the present invention has a built-in timer reservation function and multiple types of tuners, and can turn on the power to each tuner independently.
/OFF, and at least one of the multiple types of tuners is provided with a dedicated output terminal, and if a time reservation is set that exceeds the remaining recording time of the tape when recording by timer reservation, the recording operation to the tape is performed. By configuring the tuner output signal to be outputted from the dedicated output terminal from the end of the reservation until the expiration of the reservation setting time, the above-mentioned drawbacks of the conventional device have been solved.

〔Example〕

An embodiment of the recording/reproducing apparatus of the present invention will be described using a VTR as an example with reference to the accompanying drawings. FIG. 1 is a block diagram showing the main parts of a VTR10 which is an embodiment of the present invention. In this figure, the same components as those of the conventional device 1 shown in FIG. Detailed explanation will be omitted. The main features of the VTR10 of the present invention are, as is clear from comparing FIG. 1 and FIG.
N70[F switch Swl is dedicated to BS tuner 4, and a new switch SW is installed on the terrestrial broadcasting tuner 5 side (the reverse combination is also possible), and these switches S
v1. By configuring the Sv4 systems to be opened and closed independently by the timer CPU 16, each tuner 4.5 can be turned on and off independently.

In addition to the output terminal olJt1, the VTR 10 is also provided with output terminals such as 2° (ka*).In the embodiment shown in FIG. Although it is designed exclusively for the broadcast tuner 5, the configuration is not limited to this, and it may be configured such that any tuner can be selected by, for example, being connected to the output terminal side of the selection switch 5sv2.

Furthermore, it goes without saying that each tuner may be provided with a plurality of output terminals. With this configuration, the monitor device 2 can be connected to the output terminal shaft 2, and other VTRs 9 can be connected.
(In addition to conventional models such as VTRLs, recording and reproducing devices other than VTRs may also be used) can be connected as many as the number of terminals.

Furthermore, when recording by timer reservation, if a time reservation is set that exceeds the remaining recording time of a magnetic tape (not shown) installed in a predetermined storage location in the VTR 10, the timer reservation is performed on the magnetic tape. Even after the recording operation is completed, the timer CPU 16 is configured not to open the switches Svl and SW2 until the reservation setting time has expired. As a result, the tuner output signal is output from the output terminal shaft 2 even after the magnetic tape is used up, so the VTR 9 is connected to the output terminal shaft 2 and the recording operation is included at the (scheduled) recording end time by the VTR 10. If you set the timer of VTR9,
It is possible to timer record programs that are longer than the recordable time of the magnetic tape being used, and the VTR10 can be recorded during the program.
Even if the magnetic tape on the VTRQ side is used up, the entire program can be watched by playing back the magnetic tape on the VTRQ side. In a similar manner, by connecting another VTR to another output terminal shaft 4 to configure a system, continuous recording for an even longer period of time becomes possible.

The VTR10 of the present invention can be used in several other ways in addition to the above-mentioned ways. For example, by switching switch SW2 to terrestrial broadcast tuner 51111J, VT
The R10 itself can record TV programs such as VHF and IJHF (
It is also possible to record (or monitor) the BS broadcast on another VTR 9 (possibly without a BS tuner) while recording (or monitoring) the BS broadcast.

Timer CPU16, which can be said to be the main component of VTRl0
For example, the timer CPU 16 may be programmed to operate as shown in the flowchart in FIG. It is configured to enable control of the tuner's power supply, channel selection, etc.

■When power is OFF except for VTR tuner and timer ■VT
R playback mode - VTR timer mode standby <even if the BS tuner is set to the timer) - normal recording mode with terrestrial broadcast tuner 5 selected and connected Note that this flowchart and Figure 1. As shown,
In this embodiment, there are two ON/OFs, SV1+ and Sv.
An F switch is provided, and when the magnetic tape loaded in the VTR10 is finished using, the switch Swl remains closed until the reserved time expires, and only the switch SW1 is opened. There is no need for this configuration. In other words, only one ON/OFF switch is provided in the conventional device 1, and instead, the ON/OFF switch is not opened when the use of the magnetic tape is finished (and tape running is stopped), but only when the timer scheduled recording ends. It may be configured to open.

However, the configuration as shown in FIG. 1 is more advantageous because power consumption can be saved.

In the above description, the recording and reproducing apparatus of the present invention will be described as a recording and reproducing apparatus for recording and reproducing both video and audio signals using magnetic tape.
I explained using TR as an example, but if it is a recording/playback device that has a built-in timer reservation function and multiple types of tuners, then VT
The present invention is not limited to R, and may be an apparatus that performs recording and reproduction using, for example, a DAT, an optical disk, or a magneto-optical recording medium.

〔effect〕

Since the recording and reproducing apparatus of the present invention is configured as described above, it eliminates the drawbacks of the conventional apparatus and can accommodate a plurality of recording and reproducing apparatuses (BS
By connecting a BS tuner (even one without a tuner), it is possible to timer record a program longer than the recordable time of a single recording medium, and it is possible to use a recording/playback device or monitor device that does not have a BS tuner at the output terminal. If connected,
It has excellent features such as being able to use the device of the present invention as an adapter, watching BS broadcast programs on a monitor device, and simultaneously recording programs selected by a terrestrial broadcast tuner.
