The second control unit 13 drives the video data recording unit 14 according to the recording key input signal, and the first control unit so that the broadcast video signal processed by the first signal processing unit 10 is recorded in the video data recording unit 14. The broadcast signal is recorded in the video data recording unit 14 by providing a control signal to the digital video recorder 14.

In addition, as another example of the recording method, the user makes a recording reservation by inputting a channel and a broadcasting time or G code, and sets the recording to be automatically performed. Subsequently, when the set time is reached, the video signal received from the channel set at the broadcasting time set in the video data recording unit 14 may be automatically recorded.

As described above, when the video signal recorded in the video data recording unit 14 is to be reproduced, the video data recorded by the video data reproducing unit 15 according to the control signal of the second control unit 13 by the user's playback key input. Is reproduced and displayed on the display unit 11 through the second signal processing unit 16. At this time, the currently received broadcast video signal output through the first signal processing unit 10 is cut off to the display unit 11 according to the blocking control signal of the first control unit 12.

As such, when the temporary data is incident from the outside while the user views the image data reproduced by the image data reproducing unit 15 on the display unit 11, the user is restricted from watching TV due to the reflection of light.

As described above, the TV or the TVCR according to the related art displays an image that is reproduced on the TV screen when a user inputs a certain amount of light from the outside while the user is watching or viewing the image data recorded on the VCR while watching TV. There is a problem that data cannot be properly viewed.

In addition, if the video data played back due to light incident from outside during TV viewing cannot be properly viewed, there is a method of recording the video data played back while the light is incident on the VCR to re-view the video data. Has to input the recording key of the VCR part one by one, and another problem occurs that some part of the image data passes even when the VCR is recorded.

In addition, if the video data recorded on the VCR is displayed on a TV screen and the video data played back due to light incident from the outside cannot be properly viewed, the playback mode can be changed with the stop key input to replay the video data. After switching to the stop mode, another problem causing trouble to the user occurs because the user must block the light incident in the room or wait until there is no light incident and play again.

Accordingly, the present invention has been made to solve the above-mentioned problems according to the prior art, an object of the present invention is to detect when a certain amount of light is incident to the TV viewing is limited by the amount of light or more during the TV viewing incident is a certain amount of light incident In the present invention, there is provided an apparatus for controlling temporal recording of adaptive illuminance video data of a TVCR, which records broadcast video data reproduced during playback on a magnetic recording medium of a VCR, and displays a warning message indicating that the video is currently being recorded due to external light incident on the screen.

Hereinafter, an embodiment of an illuminance-adaptive image data temporary recording / playback control apparatus and a method thereof according to the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a block diagram illustrating an apparatus for temporarily adapting a roughness-adaptive video data recording apparatus according to the present invention. Referring to FIG. 2, the same components as those of the prior art shown in FIG. 1 will be described. Will be omitted.

A light detector 20 which detects the amount of light incident on the display unit 28 through the first and second signal processor 23 while the image data is being displayed; A comparison unit 21 for comparing the amount of light detected by the light detection unit 20 with a predetermined reference light amount; The image data recording control signal and the image data reproducing unit 26 reproduce the broadcast video signal to be reproduced when the amount of light detected as a result of the comparison by the comparing unit 21 is larger than the preset reference light amount in the image data recording unit 25. A control unit 22 is further provided to provide a blocking control signal so that image data cannot be displayed on the display unit 28.

In addition, the storage unit 24 for storing a warning message to notify the user of the incident light when the amount of light detected by the light detector 20 is greater than the predetermined reference light amount; In addition, an OSD processing unit 29 is further provided to OSD process the display unit 28 to display the warning message stored in the storage unit 24 according to a control signal of the control unit 22.

The operation of the illuminance-adaptive image data temporary recording control device having such a configuration will be described.

First, when a broadcast video signal transmitted from a broadcasting station is received through an antenna (not shown) and input to the first signal processor 23, the first signal processor 23 converts the received broadcast video signal into a format that can be viewed by a user. It is converted and displayed on the display unit 28 according to the control signal of the controller 22.

When a broadcast image signal is displayed on the display unit 28 and a light of a predetermined amount or more is incident from the outside while the user is watching, the light detector 20 detects the amount of light incident on the display unit 20.

The amount of light detected by the photodetector 20 is applied to the comparator 21, and the comparator 21 compares the signal level of the applied light amount with a reference level of the preset light amount and outputs a comparison result to the controller 22. do.

If the amount of light detected as a result of the comparison in the comparison unit 21 is smaller than the preset light amount, the controller 22 determines that the user does not interfere with watching TV, and continuously displays the broadcast video signal on the display unit 28. Done.

On the contrary, if the amount of light detected as a result of the comparison in the comparison unit 21 is greater than the preset light amount, the control unit 22 determines that the user is limited by the light incident upon watching the TV, and receives the image data recording control signal. The image data output unit 25 outputs the image data output control signal from the first signal processor 23 to the image data recorder 25.

Therefore, the broadcast video signal processed by the first signal processor 23 is recorded (recorded) in the video data recorder 25 while light of a predetermined amount or more is detected. At this time, the display unit 28 is continuously displaying a broadcast video signal, and counts the broadcast channel and the recording time which are being recorded and stores them in the storage unit 24.

As described above, even while the broadcast video call is recorded in the image data recording unit 25, the light detector 20 detects the amount of incident light continuously. When the detected amount of light becomes smaller than the reference light amount, the controller 22 controls the first signal. A recording stop signal is provided to the processing unit 23 and the image data recording unit 25 to stop the recording (recording) operation.

Then, a warning message stored in the storage unit 24, that is, a warning message "The broadcast video signal is recorded on the VCR due to the incident of light that may be limited to watching TV" and the broadcast channel and recording time data of the recorded broadcast video signal are recorded. The lead is provided to the OSD processing unit 29.

The OSD processing unit 29 displays the various data provided on one screen or the full screen of the display unit 28 so that the user can check the data.

Subsequently, the part which fails to watch the video signal broadcast due to the incident of light of a predetermined amount or more is converted into the video data playback part 26 by the video data of the unviewed part recorded in the video data recording part 25 according to the input of the playback key of the user. The display unit 28 reproduces the display unit 28 so that the display unit 28 can view the image.

Next, let's look at the control operation due to the incident light when playing the video data recorded on the video tape of the VCR rather than the TV broadcast signal.

The playback of image data recorded on the video tape by inserting the video tape into the VCR is performed by displaying the image data recorded in the image data recording unit 25 in the VCR through the image data reproducing unit 26 and the second signal processing unit 27. If light of a predetermined amount or more is incident from the outside while the user is watching a video while being displayed on (28), the amount of light incident by the light detector 20 is detected.

The amount of light detected by the light detector 20 is applied to the comparator 21, and the comparator 21 compares the applied light amount with a preset reference light amount and outputs a comparison result to the controller 22.

The controller 22 determines that the detected amount of light is less than the preset light amount as a result of the comparison by the comparator 21, so that the user does not interfere with viewing the image data reproduced by the image data reproducing unit 26 and continues. As a result, the image data reproduced on the display unit 28 is displayed.

On the contrary, when the amount of light detected as a result of the comparison in the comparison unit 21 is larger than the preset light amount, the controller 22 is limited by the light incident upon the user watching the image data reproduced by the image data reproducing unit 26. In response to the determination, the video data playback unit 26 provides the playback stop control signal. Therefore, the reproduction operation of the image data is stopped so that the image data is not displayed on the display unit 28.

At the same time as the reproducing operation is stopped, the controller 22 reads the warning message " unable to reproduce the VCR due to light incident " from the storage 24 and provides it to the OSD processing unit 29.

The OSD processing unit 29 processes the OSD so that the warning message provided by the control unit 22 can be displayed on the display unit 28 so that the user can confirm that the VCR reproduction is not performed due to the incident light, rather than a mechanical device failure. The display 28 is displayed.

As described above, even while the operation of the image data reproducing unit 26 is stopped, the light detector 20 detects the amount of incident light continuously. When the detected amount of light becomes smaller than the reference light amount, the controller 22 controls the image. The stop mode of the data reproducing section 26 is canceled and the mode is switched back to the reproducing mode. Accordingly, the display unit 28 displays the image data reproduced by the image data reproducing unit 26 so that the user can watch continuously.

As described above, a method of controlling the temporal recording / reproduction control of illuminance-adaptive video data according to the present invention will be described.

3 is an operation flowchart illustrating a method of controlling temporal recording / reproducing illuminance-adaptive video data according to the present invention.

First, after the TV and the VCR are turned on, a broadcast video signal or a video signal reproduced by the video data reproducing unit 26 of the VCR is displayed on the display unit 28 of the TV (S101).

When an image signal is displayed on the display unit 28, the controller 22 detects a source of the image signal displayed on the display unit 28 (S102).

Let us consider the case where the source of the video signal is a broadcast video signal transmitted from a broadcasting station.

When the source of the image data being displayed is a broadcast video signal, the amount of light incident from the light detector 20 into the room is detected while the broadcast signal is displayed (S103).

It is compared whether the amount of light detected by the light detector 20 is greater than the preset reference light amount (S104). As a result of the comparison, if the detected light amount is smaller than the reference light amount, the broadcast video signal is continuously displayed on the display unit 28. If the detected light amount is lower than the reference light amount, the control mode is output to switch the operation mode of the VCR to the recording mode. do.

When the recording mode is changed, the broadcast video signal reproduced on the display unit 28 is recorded (recorded) in the video data recording unit 25, and the corresponding channel of the recorded video signal is stored in the storage unit 24 and simultaneously recorded ( Recording) starts counting time (S105). At this time, the display unit 28 is in a state where the broadcast video signal is displayed.

While recording, the photodetector 20 continuously detects the amount of incident light and compares the detected amount of light with a predetermined reference light amount (S106). When the amount of light detected as a result of the comparison is smaller than the reference light amount, the counting of the recording time is stopped and the counted recording time is stored in the storage unit 24.

Then, the control unit 22 switches the switched recording mode back to the stop mode again to stop recording (recording) of the broadcast signal (S107), and the TV broadcast video signal due to the incident of light stored in the storage unit 24 VCR. A warning message indicating that the recording has been recorded, and the channel and the recording time stored in the storage unit 24 are displayed on the display unit 28 (S108). In this case, the display unit 28 may be a screen or a TV screen attached to the main body of the VCR.

Therefore, the broadcast video signal of the part not viewed by the incident light amount can be reproduced later and viewed according to the user's selection of the video signal recorded in the video data recording unit 25.

Next, a case in which a video signal source is a video signal reproduced in a VCR will be described with reference to FIG. 3.

If the source of the video signal displayed on the display unit 28 is a video signal reproduced by the VCR, the amount of light incident on the room from the photodetector 20 is detected while the video signal is displayed (S109).

The amount of light detected by the light detector 20 is greater than the preset reference light amount (S110). As a result of the comparison, if the detected light amount is smaller than the reference light amount, the video signal reproduced by the image data reproducing unit 26 of the VCR is continuously displayed on the display unit 28. If the detected light amount is smaller than the reference light amount, one control signal is returned. The output mode switches the operation mode of the VCR from the playback mode to the stop mode (S111).

In the stop mode, the controller 22 reads a warning message indicating that the reproduction operation is stopped due to the incident of the light stored in the storage unit 24 and displays it on the display unit 28 through the OSD processing unit 29 so that the user can enter the light. To be confirmed (S112). In this case, the display unit 28 may be a screen of the TV, or may be a screen attached to the main body of the VCR.

Even while the stop mode is continued, the photodetector 20 continuously detects the incident light amount and compares the detected light amount with a preset reference light amount (S113). When the detected amount of light is smaller than the reference light as a result of the comparison, the controller 22 switches the stopped mode back to the playback mode to continuously display the video signal reproduced by the video data reproducing unit 26 to the display unit 28. Display (S113). Therefore, the video signal reproduced by the video data reproducing section 25, that is, the playback screen can be viewed continuously.

The present invention may be applied to a TVCR which is a combination product of a TV and a VCR, or may be applied to a product in which a TV and a VCR are separated. It is also possible to connect a TV and a VCD player.

Apparatus and method for controlling temporal recording / reproducing video data according to the present invention display a broadcast signal and a video signal played by a VCR on a screen of a TV so that a user who is restricted to watching TV enters while the user is watching In the case of the broadcast signal, the broadcast signal displayed while the light is incident is stopped on the recording medium of the VCR and the video signal reproduced from the VCR, and a warning message is output to the user for incident light. In this case, there is an advantage in that the user can continuously view the video screen to be watched.

Therefore, there is an effect that it is possible to provide a high-performance product that can cope with any incident light even if incident light.
