3A to 3B are flowcharts illustrating an interesting part notice method in a TVCR for solving the present invention.

Step (S301) of checking whether the TVCR power is on, watching the selected video (TV or VCR) when the TVCR power is turned on (S302), and notice of the interest during the selected video (eg, VCR) Checking whether the function is on (S303), and if there is no key input as a result of the confirmation, the step S302 is performed when the interesting part notice function is off. Selecting a notice function (eg, voice, video, background music) (S304), and receiving a composite video signal (CVBS) reproduced by the deck 600 as an analog signal when the notice function is selected (S305); Converting the composite video signal received as an analog signal into a digital signal (S306), selecting code data of the composite video signal CVBS converted into a digital signal (S307), and the selected notice function and code data. Comparing the data with the step S308 Step S309 of determining whether to match, step S308 if the compared data does not match, and checking the code level if the compared data is matched (S310), the checked code level and selected notice A time at which the function is read (S311), the read data is input to the image processor 300 (S312), and the A / D converted composite video signal CVBS is counted in step S306. Delaying a predetermined time according to the step (S313), converting the delayed composite video signal (CVBS) to an analog signal and input to the image processor 300 (S314), and processing the input signals to the CRT (400) screen Watching the video displayed in step (S315), and the step of checking whether the interest portion notification function is off (S316) and if there is no confirmed key input result is returned to the step (S304) if the interest portion notification function is on There is a key input, so the interesting part notice function If it is off, it is shown to return to step S302.

Looking at the working state of the present invention made as described above are as follows.

The process of selecting and describing a broadcast channel of a TV to be watched by a user by operating the key input unit 220 while the power is applied is already described in the conventional description, and thus, the description thereof is omitted, and the VCR mode in the TVCR presented in the present invention is omitted. The case where the selection is made will be described as an example.

When the viewer selects the VCR mode by operating the key input unit 220 in the state in which the TVCR power is turned on (S301), the deck 600 is controlled by a control signal processed by the system controller 500 associated with the microcomputer 200. The video signal reproduced by reproducing the video / audio signal from the recording medium is processed by the video processor 300 through the video signal.

Accordingly, the image processor 300 processes the image signal reproduced from the deck 600 by the control signal of the microcomputer 200, amplifies the image signal to a predetermined level through the image amplifier 320, and reproduces the image signal on the screen of the CRT 400. The displayed video signal is displayed so that the viewer can watch the video played back on the VCR deck 600 by the TVCR (S302).

While watching the VCR through the TVCR, the microcomputer 200 associated with the system controller 500 checks whether an interesting part notice function is on (S303).

As a result of the check, if there is no key input to turn on the interesting part notice function in the key input unit 220, the microcomputer 200 considers the interesting part notice function to be off and continuously watches the video played on the VCR deck 600. (S302).

However, if there is a key input for turning on the interesting part notice function in the key input unit 220, the microcomputer 200 allows the viewer to directly select the notice function through the notice function selection unit 712 (S304).

When the preview function is selected (for example, an image), the microcomputer 200 receives the composite video signal (CVBS) reproduced by the deck 600 by the CVBS receiver 716 as an analog signal (S305) to convert the A / D. The composite video signal CVBS received as an analog signal through the unit 718 is converted into a digital signal (S306) to select code data of the composite video signal CVBS received by the code selector 720 (S307). The comparison unit 714 compares the image signal of the preview function selected by the preview function selection unit 712 with the composite video signal CVBS from which the code data is selected (S308), and determines whether or not both data match.

If the data compared in the comparison unit 714 does not match, the microcomputer 200 continuously transmits a control signal to the comparison unit 714 through the command reception control unit 710 to perform the notification function selected by the advance function selection unit 712. The video signal and the code data are compared with the selected composite video signal CVBS (S308) to continuously determine whether the two data are identical (S309).

Thus, if the data compared in the comparing unit 714 match, the matched signal is output, and the level of code data compared through the code level checking unit 722 is checked (S310) and input to the reading unit 730.

Therefore, the reading unit 730 receives the image selected by the preview function selection unit 712 and the code level confirmed by the code level checking unit 722 and reads the data (S311) to read the image through the output unit 732. Input to the processor 300 (S312).

Meanwhile, the delay unit 724 delays the composite video signal CVBS, which is converted into a digital signal by the A / D converter 718 of the front end, by a predetermined time according to the time counted by the counter 726 (S313). A digital converter converts the digitalized composite video signal CVBS into an analog signal through the A converter 728 and inputs the same to the image processor 300 (S314).

Accordingly, the image processor 300 processes the notice signal input from the output unit 732 and the delayed image signal input from the D / A converter 728 and amplifies the signal to a predetermined level through the image amplification unit 320. 400, the screen is displayed on the viewer to watch the notice screen of the portion of interest (S315).

After the viewer views the notice screen of the interesting part, the microcomputer 200 checks whether the interesting part notice function is off (S316).

If there is no key input for turning off the notice function of the interest portion in the key input unit 220, the microcomputer 200 allows the viewer to select the notice function from the above process. In order to perform the process again, and if there is a key input for turning off the interesting part notice function in the key input unit 220, the control signal outputted through the command receiving control number 710 is cut off so that the interesting part notice function is turned off. Switch to provide the viewer with the initially selected image.

As described above, the present invention can prevent viewers from leaving their seats and concentrate their attention by preliminary notifying an interesting part of a program to be watched to a viewer when watching a TVCR on a CRT screen, and helping to view a peak part such as a climax. Has the effect.

Although the present invention has been described with respect to a TVCR control apparatus and method having an interesting part notice function as described in the claims, the present invention is not limited to this, and those skilled in the art can be applied and modified in various ways. will be.
