Abstract

<P>PROBLEM TO BE SOLVED: To provide an integrated television set having a function capable of reproducing images without interrupting them even if there are parts poor in recording states in a magnetic tape. <P>SOLUTION: When a magnetic tape is reproduced by a VCR 2 and if there are parts poor in recording state in the magnetic tape, a user sometimes cannot see reproduced images if they are reproduced as they are. A system controller 13 compares an envelope signal level of a tracking error signal from the VCR 2 with a predetermined threshold. When the envelope signal level becomes less than a threshold, the system controller 13 switches a Y/C signal to a composite signal and inputs the composite signal to a signal processing circuit 8 of a television set 7. The signal processing circuit 8 generates an RGB signal on the basis of the inputted composite signal and outputs it. Consequently, the user can see the reproduced images even if a section poor in the recording state of the magnetic tape is reproduced. <P>COPYRIGHT: (C)2006,JPO&NCIPI

In such a conventional integrated television apparatus, the composite signal from the VCR unit 2, the tuner unit 1 and the external input terminal AUX is Y / C separated by the signal processing circuit 6 of the DVD recorder unit 5 and is sent to the television unit 7a. Since it is supplied, it is possible to obtain a clear image with high resolution and no influence of noise. However, if there is a badly recorded part on the magnetic tape reproduced by the VCR unit 2, the DVD to which the composite signal is input is input. The signal processing circuit 6 of the recorder unit 5 cannot perform analog / digital conversion or digital / analog conversion normally, and for this reason, blocking noise is generated, and as a result, the recording state of the magnetic tape is poor. This causes a problem that the reproduced image becomes invisible and the image is interrupted.

The prior arts of Patent Documents 1 and 2 do not relate to an integrated television apparatus in which a magnetic recording / reproducing apparatus, an optical disk recording / reproducing apparatus, and a television receiver are integrated.

The present invention has been made to solve the above-described problems, and an integrated television apparatus having a function capable of reproducing an image without interruption even when a magnetic tape has a bad recording state. The purpose is to provide.

In order to achieve the above object, the invention of claim 1 includes a tuner unit for receiving a television broadcast,
A VCR unit for recording / reproducing information with respect to a magnetic tape; a DVD recorder unit for recording / reproducing information with respect to a DVD; and a TV unit for displaying a screen of a television broadcast received by the tuner unit and outputting sound. And selecting a composite signal from the tuner unit, a composite signal from the VCR unit, or a composite signal from an external input terminal, and inputting the selected signal to the signal processing circuit of the DVD recorder unit. The composite selection means and the composite signal from the Y / C signal outputted from the composite signal processed by the signal processing circuit of the DVD recorder unit and the composite signal from the composite selection means are selected. Y / composite selection means, the C signal from the signal processing circuit of the DVD recorder section, and the composite C / 3.58 selection means for selecting any of the 3.58 MHz carrier color signals extracted from the signal, the composite selection means, the Y / composite selection means, the C / 3.58 selection means, and the entire apparatus And a system controller for controlling the composite video signal from the VCR by controlling the composite selection means to control the composite selection means. And the envelope signal level of the tracking error signal used for the tracking servo in the VCR is compared with a predetermined threshold value. When the envelope signal level becomes less than the threshold value, the Y / composite selecting means and By controlling the C / 3.58 selection means, it is possible to control Switching the pogitt signal in real time or switching with a time lag, inputting the composite signal to the signal processing circuit for outputting the RGB signal of the television unit, and the Y / composite selecting means when the envelope signal level exceeds a threshold value And switching the composite signal to the Y / C signal in real time by controlling the C / 3.58 selection means, or switching with a time lag, and inputting the Y / C signal to the signal processing circuit of the television section. An integrated television device is provided.

In this configuration, when the image recorded on the magnetic tape is reproduced by the VCR unit,
If there are badly recorded parts or scratches on the magnetic tape, the signal processing circuit of the DVD recorder unit cannot perform analog / digital conversion or digital / analog conversion sufficiently,
As a result, blocking noise may occur and the reproduced image may not be visible. Therefore, the system controller compares the envelope signal level of the tracking error signal from the VCR unit with a predetermined threshold value, and when the envelope signal level becomes less than the threshold value,
The Y / C composite selection means and the C / 3.58 selection means are controlled to switch from the Y / C signal to the composite signal with real time or time lag.

As a result, the composite signal from the VCR unit is directly input to the TV unit, and the signal processing circuit of the TV unit generates an RGB signal based on the input Y signal and the 3.58 MHz carrier color signal. Output. Therefore, in this case, even if a section in which the recording state of the magnetic tape is bad is reproduced, the reproduced image does not disappear.

When the recording state of the magnetic tape passes a bad section, the envelope signal level becomes equal to or higher than the threshold value. Therefore, the system controller detects that the envelope signal level exceeds the threshold value and outputs a signal input to the television unit. The composite signal is switched from the composite signal to the Y / C signal with a real time or time lag, and the Y signal and the C signal are input to the signal processing circuit of the television section. Thereby, the signal processing circuit of the television section generates and outputs an RGB signal based on the input Y signal and C signal.

Therefore, according to this configuration, when there is a bad recording state on the magnetic tape, the signal input to the television section is switched from the Y / C signal to the composite signal.
Since the composite signal from the VCR unit is directly input to the television unit, the reproduced image can be displayed without interruption, and the reproduced image can be comfortably viewed by the viewer. Also, if the DVD recorder has high analog / digital conversion or digital / analog conversion performance, both signals can be switched in real time, but if the switching cannot be followed in real time, a time lag should be provided. By switching between the Y / C signal and the composite signal, it becomes possible to follow the switching.

According to a second aspect of the present invention, there is provided a tuner for receiving a television broadcast, a magnetic recording / reproducing unit for recording / reproducing information on / from a magnetic tape, and an optical disk recording / reproducing unit for recording / reproducing information on / from an optical disk. In an integrated television apparatus comprising a television section for displaying a screen of a television broadcast received by the tuner section and outputting sound, a signal processing circuit of the optical disc recording / playback section by selecting a composite signal from the magnetic recording / playback section When the envelope signal level is less than the threshold, the envelope signal level of the tracking error signal used for tracking servo in the magnetic recording / reproducing unit is compared with a predetermined threshold. The signal processing is switched from the signal to the composite signal and the composite signal is output as the RGB signal of the television section. A system controller for controlling the input to the signal processing circuit of the television section by switching from the composite signal to the Y / C signal when the envelope signal level exceeds a threshold value. An integrated television device is provided.

In this configuration, when the image recorded on the magnetic tape is being reproduced by the magnetic recording / reproducing unit, if there is a badly recorded part or scratch on the magnetic tape, the signal processing circuit of the optical disc recording / reproducing unit is reproduced as it is. The analog / digital conversion or the digital / analog conversion cannot be performed sufficiently, which may cause blocking noise and make the reproduced image invisible. Therefore, the system controller compares the envelope signal level of the tracking error signal from the magnetic recording / reproducing unit with a predetermined threshold, and switches the Y / C signal to the composite signal when the envelope signal level falls below the threshold, The composite signal is input to the signal processing circuit of the television section.

Thus, the composite signal from the magnetic recording / reproducing unit is directly input to the television unit, and the signal processing circuit of the television unit generates and outputs an RGB signal based on the input composite signal. Therefore, in this case, even if a section in which the recording state of the magnetic tape is bad is reproduced, the reproduced image does not disappear.

When the recording state of the magnetic tape passes a bad section, the envelope signal level becomes equal to or higher than the threshold value. Therefore, the system controller detects that the envelope signal level exceeds the threshold value and outputs a signal input to the television unit. The composite signal is switched to the Y / C signal, and the Y signal and the C signal are input to the signal processing circuit of the television section. Thereby, the signal processing circuit of the television section generates and outputs an RGB signal based on the input Y signal and C signal.

Therefore, according to this configuration, when there is a bad recording state on the magnetic tape, the signal input to the television section is switched from the Y / C signal to the composite signal.
Since the composite signal from the magnetic recording / reproducing unit is directly input to the television unit, the reproduced image can be displayed without interruption, and the reproduced image can be comfortably viewed by the viewer.

According to a third aspect of the present invention, in the second aspect of the invention, the DVD recorder unit is selected by selecting one of a composite signal from the tuner unit, a composite signal from the video cassette recorder unit, and a composite signal from an external input terminal.

Since the / composite selection means, the C / 3.58 selection means and the entire apparatus are controlled via the control bus, switching between the Y / C signal and the composite signal input to the signal processing circuit of the television section can be easily realized. be able to.

In the invention of claim 4, in the invention of claim 2, switching from the Y / C signal to the composite signal and switching from the composite signal to the Y / C signal are performed with real time or a time lag. If the performance of analog / digital conversion and digital / analog conversion of the optical disc recording / playback unit is high, the switching of both signals can be performed in real time, but if the switching cannot be followed in real time, a time lag is provided. If switching between the Y / C signal and the composite signal is performed, it becomes possible to follow the switching.

In the invention of claim 5, in the invention of claim 2, since the magnetic recording / reproducing unit is a video cassette recorder unit and the optical disc recording / reproducing unit is a DVD recorder unit, the magnetic recording / reproducing unit requires a small space, As an optical disc recording / reproducing unit, it is possible to record a large amount of image information. Therefore, an integrated television device requires a small space other than the television unit, and is not different from a single television receiver in terms of design. Things can be realized,
In addition, since the video cassette recorder unit and the DVD recorder unit are also provided, it is easy to use and can be obtained at a lower cost compared to purchasing separately.

As described above, according to the present invention, when there is a bad recording state on the magnetic tape, the signal input to the television section is switched from the Y / C signal to the composite signal.
Since the composite signal from the CR unit is directly input to the television unit, the reproduced image can be displayed without interruption, and the reproduced image can be comfortably viewed by the viewer. In addition, if the performance of analog / digital conversion and digital / analog conversion of the optical disc recording / playback unit is high, the switching of both signals can be performed in real time, but if the switching cannot be followed in real time, there is a time lag. By switching between the Y / C signal and the composite signal, it becomes possible to follow the switching.

Further, according to the present invention, when the recording state is poor on the magnetic tape, the signal input to the television unit is switched from the Y / C signal to the composite signal, that is, the composite from the magnetic recording / reproducing unit. Since the signal is directly input to the television section, the reproduced image can be displayed without interruption, and the reproduced image can be viewed comfortably for the viewer.

In order to control the tuner 1, VCR unit 2, DVD recorder unit 5, television unit 7, etc. The system controller 13 is provided. The system controller 13 controls each component via a control bus. L1
˜L9 indicates lines included in the control bus.

Further, this integrated television apparatus selects any one of the composite signal from the tuner unit 1, the composite signal from the VCR unit 2, and the composite signal from the external input terminal AUX.

A Y / composite selection switch 9 for selecting either the Y signal (luminance signal) of the C signals or the composite signal from the composite selection switches 3 and 4, and the C signal from the signal processing circuit 6 of the DVD recorder unit 5 (Color difference signal) and 3.5 extracted from the composite signal
And a C / 3.58 selection switch 10 for selecting one of the 8 MHz carrier color signal.

When the Y / composite selection switch 9 selects the composite signal, the 3.58 trap circuit 11 removes the 3.58 MHz carrier color signal from the composite signal and inputs the composite signal to the signal processing circuit 8 of the television unit 7. The 3.58 selection switch 10 selects the 3.58 MHz carrier color signal extracted by the 3.58 extraction circuit 12 and inputs the same to the signal processing circuit 8 of the television unit 7. In the signal processing circuit 8, 3.5 from the internal 3.58 MHz oscillator.
Based on the 8 MHz signal and the Y signal, an RGB signal is generated from the 3.58 MHz carrier color signal and output.

The Y / composite selection switch 9 selects the Y signal from the signal processing circuit 6 of the DVD recorder unit 5, and accordingly, the C / 3.58 selection switch 10 also receives the C signal from the signal processing circuit 6.
When the signal is selected, the Y signal and the C signal are input to the signal processing circuit 8 of the television unit 7. Thereby, the signal processing circuit 8 generates and outputs an RGB signal based on the Y signal and the C signal. When the Y / composite selection switch 9 selects the Y signal, Y
The signal passes through the 3.58 trap circuit 11 as it is.

The system controller 13 is characterized in that the composite selection switches 3 and 4 are controlled to select a composite signal from the VCR unit 2 and input it to the signal processing circuit 6 of the DVD recorder unit 5. Envelope signal comparison means 1 uses an envelope signal level of a tracking error signal used for tracking servo and a predetermined threshold value.
4, when the envelope signal level becomes less than the threshold value, the Y / composite selection switch 9 and the C / 3.58 selection switch 10 are controlled, and the signal switching means 15
When the C signal is switched to the composite signal in real time, or switched with a time lag, the composite signal is input to the signal processing circuit 8 that outputs the RGB signal of the television unit 7, and when the envelope signal level exceeds the threshold value, Y / The composite selection switch 9 and the C / 3.58 selection switch 10 are controlled to switch from the composite signal to the Y / C signal in real time, or with a time lag, and the Y / C signal is switched to the signal processing circuit 8 of the television section 7. To enter.

FIG. 2 is a diagram showing the relationship between the magnetic tape and the tracking error signal envelope signal during the VCR reproduction operation in this embodiment. FIG. 3 is a flowchart for explaining the switching operation between the Y / C signal and the composite signal during the VCR reproduction operation in this embodiment.

The characteristic operation of the integrated television apparatus shown in FIG. 1 will be described with reference to FIGS. For example, when an instruction for reproducing the VCR unit 2 is given to the system controller 13 from a remote controller (not shown), the system controller 13 sets the composite selection switch 3 to the VCR unit 2 side, and sets the composite selection switch 4 to the composite selection switch. Set to 3 side. That is, the system controller 13 selects the composite signal from the VCR unit 2 (step S1). As a result, the DVD recorder unit 5 receives the composite signal from the VCR unit 2 and performs analog / digital conversion and digital / analog conversion by the signal processing circuit 6 to separate the composite signal into Y / C signals, thereby obtaining a C signal and a Y signal. Is input to the television section 7.

In the television unit 7, the Y / composite selection switch 9 is set to the Y signal side of the signal processing circuit 6 of the DVD recorder unit 5 and the C / 3.58 selection switch 10 is controlled by the system controller 13. Since it is set on the C signal side of the signal processing circuit 6,
The Y signal from the signal processing circuit 6 of the DVD recorder 5 is input to the signal processing circuit 8 via the Y / composite selection switch 9 and the 3.58 trap circuit 11, and the C signal from the signal processing circuit 6 of the DVD recorder unit 5. Is input to the signal processing circuit 8 via the C / 3.58 selection switch 10. The signal processing circuit 8 generates and outputs an RGB signal based on the C signal and the Y signal. The RGB signals are input to a display device (not shown), so that a reproduced image from the VCR unit 2 is displayed on the display device.

When the image recorded on the magnetic tape in this way is reproduced by the VCR unit 2, the system controller 13 sets the envelope signal level of the tracking error signal used for tracking servo in the VCR unit 2 (for example, 5V when normal) Voltage) and a predetermined threshold value (for example, 3V voltage), and when the envelope signal level becomes less than the threshold value (step S2), the Y / composite selection switch 9 and the C / 3.58 selection switch 10 are controlled. Thus, the signal input to the television section 7 is switched from the Y / C signal to the composite signal in real time (step S3).

If the performance of the analog / digital conversion and digital / analog conversion of the DVD recorder 5 and the switching performance of the Y / composite selection switch 9 and the C / 3.58 selection switch 10 are high, the Y / C signal is converted to the composite signal in real time. However, when the switching cannot be followed, the switching from the Y / C signal to the composite signal may be performed with a time lag. Also, Y /
Similarly, switching to the C signal may have a time lag.

By the way, for example, as shown in FIG. 2A, in a period (section) from time T1 to time T2,
If the magnetic tape 20 has badly recorded parts or scratches and is reproduced as it is, the signal processing circuit 6 of the DVD recorder unit 5 cannot sufficiently perform analog / digital conversion or digital / analog conversion, and therefore blocking noise is generated. May occur and the reproduced image may become invisible.

Therefore, when the recording state of the magnetic tape is normal, the envelope signal level of the tracking error signal used for the tracking servo in the VCR unit 2 is, for example, 5V voltage as shown in FIG. As shown in FIG. 4, in the section where the recording state is bad (period from time T to time T), assuming that the envelope signal level is less than 3V, for example, the system controller 13 determines that the envelope signal level is less than the threshold of 3V. A determination is made (step S2), and the Y / composite selection switch 9 and the C / 3.58 selection switch 10 are controlled to switch the signal input to the television device 7 from the Y / C signal to the composite signal in real time (step S3). .

As a result, the composite signal from the VCR unit 2 is directly input to the television unit 7, and the composite signal input to the 3.58 trap circuit 11 via the Y / composite selection switch 9 is a 3.58 MHz component. Is removed and only the Y signal is input to the signal processing circuit 8, and the composite signal input to the 3.58 extraction circuit 12 has a 3.58 MHz component (3.
58 MHz carrier color signal) is input to the signal processing circuit 8. The signal processing circuit 8 generates and outputs an RGB signal based on the input Y signal and the 3.58 MHz carrier color signal. Therefore, in this case, even if a section in which the recording state of the magnetic tape 20 is bad (period from time T1 to time T2) is reproduced, the reproduced image will not be invisible.

Then, when the recording state of the magnetic tape 20 passes a bad section, the envelope signal level becomes 3V voltage or higher as shown in FIG. 2B, so that the system controller 13 has the envelope signal level higher than the threshold (3V voltage). (Step S4), Y /
By controlling the composite selection switch 9 and the C / 3.58 selection switch 10 to switch the Y / composite selection switch 9 to the Y signal side and the C / 3.58 selection switch 10 to the C signal side, the television section 7 The signal input to the video signal is switched from the composite signal to the Y / C signal in real time (step S5), and the Y signal and the C signal are switched to the signal processing circuit 8 of the television section 7.
To enter. As a result, the signal processing circuit 8 performs R based on the input Y signal and C signal.
A GB signal is generated and output. In this case, the Y / Y digitally processed by the DVD recorder 5
Since the C signal is used, a particularly clear image is displayed on the display device.

After the process of step S5, the process of steps S2 to S5 is repeated until the reproduction is completed (step S6). For example, even if the magnetic tape has a bad recording state, the reproduced image is not interrupted. Can be displayed.

In this embodiment, the threshold voltage for comparing the envelope signal level is set to 3 V. However, since the envelope signal level is lowered and the level at which blocking noise is generated varies depending on the performance of the apparatus, the threshold voltage is 3 V. Not limited to. In the present embodiment, the normal envelope signal level has been described as 5 V. However, the normal envelope signal level varies depending on the apparatus, and is not limited thereto.

As described above, according to the present embodiment, when the recording state of the magnetic tape is bad, the signal input to the television unit 7 is switched from the Y / C signal to the composite signal, that is, the VCR unit. Since the composite signal from 2 is directly input to the television section 7, the reproduced image can be displayed without interruption, and the reproduced image can be comfortably viewed by the viewer. Further, if the DVD recorder unit 5 has high analog / digital conversion or digital / analog conversion performance, both signals can be switched in real time. However, if the switching cannot be followed in real time, there is a time lag. Let Y / C
If switching between the signal and the composite signal is performed, it becomes possible to follow the switching.
