A preamplifier 12 for amplifying, and an image processor 14 and an audio processor 20 for processing the video and audio signals output from the preamplifier 12, respectively.

The video signal output from the image processor 14 is output on the CRT 16 to become a video screen that a viewer can watch. In addition, the voice signal output from the voice processor 20 is output as audible voice through the speaker 18.

The image processor 14 synthesizes other signal processing and luminance signals and color signals and outputs them as primary color signals of R, G, and B so as to be suitable for outputting the image signal amplified by the preamplifier 12 to the CRT 16. . In addition, the voice processing unit 20 processes the audio signal amplified by the preamplifier 12 and outputs the audio signal that can be heard by the viewer.

In the conventional TV having the above-described configuration, only one broadcast selected by the viewer is output through the CRT 16 screen, so that even if the viewer prefers a broadcast program through a program notice column such as a newspaper or a magazine, the other broadcast program is used. Forgotten while watching the viewer did not see the desired program occurs.

The present invention has been made to solve the above problems, and the object of the present invention is to save the code of the program that the viewer wants to detect the code even while watching other broadcasts and to automatically record the TV broadcast output The present invention also provides a TV broadcast recognition device that performs recording when a specific broadcast that can be played later is input even when the user cannot see the video.

It characterized in that it comprises a system control unit for operating a VCR recording unit for recording the video.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the TV broadcast recognition device for performing recording when a specific broadcast of the present invention is input.

First, referring to FIG. 2, a TV broadcast recognition apparatus for recording a specific broadcast according to the present invention is inputted from the second tuner 22 and the second tuner 22 for station selection. A second preamplifier 24 for amplifying the output composite signal and separating the video and audio signals, a second image processor 26 for processing the video signal output from the second preamplifier 24, and A second audio processor 27 for processing the audio signal output from the second preamplifier 24 and A for modulating the analog video signal output from the second image processor 26 into a digital signal. A code recognition and detection unit (32) for recognizing and detecting a code representing a specific broadcast among the signals output from the A / D converter (28) and the A / D converter (28), and a code of a specific broadcast is stored. The code memory section 34, the code comparison section 36 for comparing the codes, and the whole The VCR recording unit 40 for recording the video and audio output from the second image processing unit 26 and the second audio processing unit 27 according to the microcomputer 30 and the control signal of the microcomputer 30. A system control 38 is shown for operating the system.

The second tuner unit 22, the second preamplifier unit 24, the second image processor 26, and the second audio processor 27 operate in the tuner unit 10 and the preamplifier. The unit 12, the image processor 14, and the audio processor 20 are essentially the same. The difference between these is that the image output from the tuner unit 10 is output through the CRT 16, but according to the present invention, the image signal input through the second tuner unit 22 is not output through the CRT 16. Input to the A / D conversion unit 28, and then to the VCR recording unit 40 via the system control unit 38, and also stored in the voice recording area of the VCR recording unit 40 as a voice signal. It is a point.

The microcomputer 30 sequentially searches for a broadcast through the second tuner 22. That is, it is controlled to tune to a program broadcasting station in which a specific broadcast designated by the viewer is broadcast. When a channel on which a specific broadcast program is broadcast is tuned, the tuned broadcast is processed by the second preamplifier 24 and then processed by the second image processor 26 as a composite signal including a code indicating a specific broadcast. Is output.

The video signal including the broadcast code thus output is input to the A / D converter 28. The A / D converter 28 is for modulating an analog signal into a digital signal, and the analog video signal is modulated into a digital video signal.

The modulated digital video signal is input to the code recognition and detection unit 32.

The code recognition and detection unit 32 recognizes a code indicating a specific broadcast in the modulated digital video signal. When a code is input, recognized and detected, it is compared with the code stored in the code memory section 34.

The code memory unit 34 stores a specific code representing a broadcast program tuned by the viewer, and the viewer may input the broadcast through the microcomputer 30. The code data of the specific broadcast stored in the code memory section 34 is compared after being read by the code comparison section 36.

The code comparison unit 36 compares the code from the code recognition and detection unit 32 with the code set and stored in the code memory unit 34 by the viewer, and if it is found that both codes are the same code, the code is the same code. Output to 30). If both codes are not the same code, a signal to the microcomputer 30 is output.

If the microcomputer 30 determines that the codes are the same, the broadcast output of the tuner unit 10 maintains the normal output, and the system control unit records the video and audio signals preferred by the viewer input from the second tuner unit 22. A control signal is output to 38.

Then, the system controller 38 receives the video and audio signals from the second image processing unit 26 and the second audio processing unit 27 and controls the VCR recording unit 40 to record them. By doing so, the video and audio are recorded even if the viewer prefers not to watch the broadcast, so that they can be played back later using the VCR playback unit.

When a specific broadcast of the present invention having the above configuration is input, a TV broadcast recognition apparatus for recording will be described in detail with reference to the block diagram of FIG. 2 and the flowchart of FIG. 3.

When power is supplied to the TV by the viewer, the TV outputs the channel stored in its own memory, that is, the broadcast of the stored channel immediately before the power is turned off. In this state, the tuner unit 10 operates to output a broadcast normally.

At the same time, the microcomputer 30 outputs a control signal to tune the broadcast input from the channel on which the program tuned by the viewer is broadcast. Accordingly, the tuner tuned to the second tuner 22 is also received.

The received broadcast signal is amplified and modulated by the second preamplifier 24 and then input to the second image processor 26. The input broadcast signal is processed into a video signal that can be output on the CRT 16. However, the voice signal processed by the second voice processor 27 is not processed at all. At this time, the broadcast input through the tuner unit 10 is normally output.

The signal processed by the second image processor 26 is input to the A / D converter 28. In the A / D converter 28, the video signal is converted from analog to digital. The digital signal is converted into a code indicating a specific broadcast, such as signal music or a title, and the like.

The signal converted into code data is again output to the code recognition and detection unit 32.

The code recognition and detection unit 32 recognizes an input code and detects whether a specific code is included. At this time, if a code similar to a specific code is input, the code recognition and detection unit 32 outputs the code to the code comparison unit 36.

When a code is input, the code comparing unit 36 reads a code stored in the code memory unit 34 to compare whether the same code exists. If the code data input from the code recognition and detection unit 32 and the code data input from the code memory unit 34 turn out to be the same code data, they are input to the microcomputer 30.

When the signal indicating that the same code is input from the code comparator 36 is input to the microcomputer 30, the microcomputer 30 outputs a control signal so that the channel currently broadcasted by the tuner 10 maintains a normal broadcast state. At the same time, a control signal is output so that a specific broadcast set by the viewer output from the second image processor 26 is recorded.

The control signal is input to the system control unit 38. The system controller 38 controls to input the VCR recording unit 40 after receiving the video and audio signals output from the second image processing unit 26 and the second audio processing unit 27 when a signal indicating start of recording is input. do. The VCR recording unit 40 stores the video and audio signals in a VCR tape that is conventionally used.

If it is found that the comparison result in the code comparison unit 36 is not the same code, the microcomputer 30 recognizes this and outputs a control signal to search for an image signal pressurized from the second tuner unit 22 again.

In the above description, the microcomputer 30 may be configured as a separate microcomputer to control only the TV broadcasting recognition apparatus of the present invention, or may use a microcomputer for the main word used in the conventional TV jointly.

As described above, when a specific broadcast of the present invention is input, the TV broadcast recognition device that performs recording detects this code even while watching another broadcast and stores the code of a program that the viewer wants to watch and automatically outputs the TV broadcast output. By recording, there is an advantage that can be reproduced later even if the broadcast is not seen.

Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that the present invention may be modified or changed within the spirit and scope of the present invention. something to do.
