Description

Important screen recording / playback device

More particularly, the present invention relates to an important screen recording / reproducing apparatus capable of automatically recording / reproducing an important screen (for example, an important screen at the time of sports relay) .

As is well known, a television tuner is used as a channel tuning means in a television that reproduces a broadcast signal propagated wirelessly from a plurality of broadcast stations, and a broadcast signal for the broadcast channel selected by the viewer is selected by the tuner.

[0005] However, when the viewer of the broadcast channel program (for example, a sports program) selected in this way is being called, or the reason is inevitable (for example, toilet access) When the important scene is repeatedly played back on a slow screen, a viewer who is out of the current viewing position can not view the important scene. Accordingly, a viewer who has not watched the important scene has a problem of having to ask the other viewers about the situation at that time.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a critical screen recording / reproducing apparatus for automatically recording / playing back important screens reproduced on a slow screen, .

In order to achieve the above object, according to a preferred embodiment of the present invention, there is provided a television having a video signal reproducing means for reproducing a video signal among broadcast signals selected by a tuner, An ID detecting section for detecting an ID signal for a significant screen in a video signal reproduced and processed by the video signal reproducing means; important screen processing means for storing and outputting the important screen; And a controller for controlling the ID detecting operation for the important screen and the storing operation for the important screen according to the setting of the key screen and controlling the important screen stored in the reproducing mode to be reproduced.

Preferably, the control function setting unit is further provided with a button for an important screen automatic recording mode and a button for a playback mode.

According to the embodiment of the present invention configured as described above, when the important screen automatic recording mode is set, a saving operation is performed for the important screen currently being played under the control of the control unit according to the signal detected by the ID detecting unit, The stored important screen is reproduced and displayed on the screen.

Hereinafter, a critical screen recording / reproducing apparatus according to an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a critical screen recording / reproducing apparatus according to an embodiment of the present invention. The embodiment of the present invention includes a tuner 10, an image IF module 12, a video signal processor 14, A channel selection unit 16, a channel selection data storing unit 18, a control function setting unit 20, an ID detecting unit 22, an A / D converting unit 24, a memory unit 26, a D / A converting unit 28, , And a control unit (30).

In this figure, the tuner 10 tunes a broadcast signal of a selected channel among the television broadcast signals received by the antenna A, amplifies the tuned signal by high-frequency amplification, and generates an intermediate frequency signal IF from the amplified high- And outputs it.

The video IF module 12 amplifies and detects the video signal of the broadcast channel selected by the tuner 10, and outputs the amplified video signal.

The video signal processing unit 14 separates the composite video signal output from the video IF module 12 into a luminance signal and a color signal, performs luminance adjustment and contrast adjustment of the separated luminance signal, and demodulates the separated color signals Then, the luminance signal and the two demodulated color difference signals are color-converted into R / G / B signals, which are display signals for color image reproduction, via a matrix circuit (not shown), and are output. In the recording mode, the video signal for the important screen is supplied to the A / D conversion unit 24 under the control of the control unit 30, which will be described later, Signal (i.e., a signal for the important screen).

The image amplifying unit 16 amplifies the image signal output from the image signal processing unit 14 to be displayed on the CRT.

The tuning channel data storage unit 18 stores tuning signal data applied to the channel tuning operation of the tuner 10, for example, tuning voltage data corresponding to the position of each channel tuning button on the control function setting unit 20 Are stored in advance.

The control function setting unit 20 typically employs a button provided on a front control panel of the television or a remote control as a remote control device to set a control function for the television. The button 20a for the important screen automatic recording mode and the button 20b for the playback mode are additionally provided so that the important recording screen of the present invention is automatically recorded on the important screen In addition, it is set so that the stored important screen is reproduced.

The ID detecting unit 22 detects the ID signal of the important screen among the video signals currently reproduced under the control of the control unit 30 to be described later.

Here, it is assumed that the ID signal for the important screen is transmitted together with the important screen in the broadcasting station.

The A / D converter 24 digitally converts the video signal (that is, the important screen) from the video signal processor 14.

The memory unit 26 stores the digital signal output from the A / D conversion unit 24 (that is, the signal for the important screen) by the recording (W) signal of the control unit 30 to be described later, And outputs the signal stored by the output (R) signal.

The D / A conversion unit 28 analog-converts the signal output from the memory unit 26 and applies the analog signal to the image signal processing unit 14 so that the image is output.

The control unit 30 controls the operation of the corresponding television according to the control function set by the control function setting unit 20 and performs the ID detection operation on the important screen in the setting of the important screen automatic recording mode assumed in the present invention, Control is performed such that the storage operation for the important screen is performed and the important screen stored at the time of setting the reproduction mode is controlled to be reproduced.

Next, the operation of the important screen recording / reproducing apparatus according to the present invention will be described.

Once the viewer sets the important screen automatic recording mode by using the button 20a provided on the control function setting unit 20 while the viewer is watching the broadcast program in progress, 30 controls the ID detector 22 to detect the ID signal of the important screen from among the video signals currently being reproduced.

Accordingly, when the ID detecting unit 22 applies a signal (e.g., a high-level signal) indicating that the ID signal for the important screen has been detected to the control unit 30, the control unit 30 controls the video signal processing unit 30, And controls the video signal processor 14 to apply the currently reproduced video signal (i.e., the important screen) to the A / D converter 24. At the same time, the control unit 30 applies a write (W) signal to the memory unit 26.

Thus, the digital-converted signal in the A / D conversion unit 24 is stored in the memory unit 26.

The signal of the important screen stored in this way is reproduced only when the reproduction mode is set. The reproduction operation is performed by setting the reproduction mode by using the button 20b once added to the control function setting unit 20 by the viewer When the reproduction mode is set, the control unit 30 provides the output R signal to the memory unit 26, so that the signal output from the memory unit 26 is supplied to the D / A conversion unit 28 And the image signal is processed by the image signal processing unit 14 and displayed on the screen.

According to the present invention as described above, not only the important screen can be automatically recorded according to the desire of the viewer but also can be reproduced, so that it is possible to repeatedly reproduce the unfortunate part (that is, the part where the important screen is displayed) Thereby maximizing the viewing satisfaction.
