4 is a schematic flowchart showing a control method of a multimedia display apparatus according to the present invention in sequence.

Referring to the drawing, first, it is determined whether the multimedia display apparatus 10 is turned on or off (step 111).

Subsequently, when it is determined that the multimedia display apparatus 10 is ON, that is, when the multimedia display apparatus 10 is in operation, the camera operating unit (or operation button) 16 provided in the main body 10a of the multimedia display apparatus 10 is turned on ( ON) to operate (ON) the CD camera 15 installed in the main body 10a (steps 120 and 130).

On the other hand, when the multimedia display apparatus 10 is turned OFF in step 111, that is, when the multimedia display apparatus 10 is not in operation, the multimedia display apparatus 10 is turned ON and the operation after the step 120 is continued. )

The microphone 33 is connected to the microphone socket 33a of the main body 10a while simultaneously outputting the image data of the CD camera 15 through the image display unit 14 through which the image of the multimedia display apparatus 10 is output. The sound input through the output through the speaker 27 is output (step 140).

In addition, it is determined whether an external storage medium, which is a portable storage device, is installed in the main body 10a of the multimedia display apparatus 10, and an external storage medium is selected.

If the USB storage device 32 is selected as the external storage medium in step 150, the USB storage device 32 is turned on by turning on the video recording unit 22 installed in the main body 10a of the multimedia display device 10. Video data, which is an image output to the image display unit 14, and audio data, which is an audio output to the speaker 27, are stored in step S161.

In this way, the video and audio data may be stored in a portable external storage medium while watching and listening to the image output to the image display unit 14 and the sound output to the speaker 27. That is, the contents of the video and audio data can be checked while being stored.

However, the present invention is not limited thereto, and the data stored in the memory 19 can be stored while being confirmed through the image display unit 14.

In order to output the video data and the audio data stored in the USB storage device 32 through the image display unit 14 and the speaker 27, the screen switching unit 34 installed on one side of the main body 10a is turned on. (Step 170)

That is, the step 170 is to display the video data and audio data stored in the USB storage device 32 on the image display unit 14 by switching the screen that was previously displayed.

In addition, the video and audio data stored in the USB storage device 32 are reproduced and output through the image display unit 14 and the speaker 27 (step 180).

If step 170 may be performed before, for example, in karaoke, step 180 may be performed in karaoke as well as, for example, in a TV or computer (PC) of a user's home or office. As a result of this execution, the video memories can be stored and carried and stored, and thus, the user can view his memories as a video anywhere.

On the other hand, if the USB storage device 32 and the flash memory card 31 are selected as the external storage medium in step 150, the video data is turned on by turning on the video recording unit 22 installed in the main body 10a. And audio data are simultaneously stored in the USB storage device 32 and the flash memory card 31, and the steps 170 and 180 are continued (step 163).

If the flash memory card 31 is selected as the external storage medium in step 150, the video recording unit 22 is turned on to store the video data and audio data in the flash memory card 31. Continue with steps 170 and 180 above (step 165).

5 is a schematic flowchart illustrating a control method of a multimedia system using a multimedia display apparatus according to the present invention in sequence.

Referring to the drawing, first, it is determined whether the multimedia display apparatus 10 is turned on or off (step 211).

Subsequently, when it is determined that the multimedia display apparatus 10 is ON, that is, when the multimedia display apparatus 10 is in operation, the camera operating unit 16 provided in the main body 10a of the multimedia display apparatus 10 is turned on. 10a) turns on the CD camera 15 built in (ON) (steps 220, 230).

On the other hand, if the multimedia display device 10 is turned off in step 211, the multimedia display device 10 is turned on and the operation after step 220 continues (step 213).

In addition, the image display unit 14 of the multimedia display apparatus 10 outputs the image data of the CD camera 15 to the speaker and the sound input through the microphone 33 provided in the main body 10a is the speaker 27. To be output (step 240).

Subsequently, it is determined whether the singing cycle period 40 is connected and installed in the multimedia display apparatus 10, and if it is connected, the singing cycle period 40 is turned on (steps 251 and 260).

On the other hand, if the singing period 40 is not connected to the multimedia display apparatus 10 in step 251, the singing period 40 is connected and the operation 260 is performed (step 253).

The video signal of the CD camera 15 and the audio signal of the microphone 33 are input to the singing cycle period 40 (step 270).

In addition, the video signal, the audio signal, and the caption signal in the singing period 40 are synthesized by the image capturing synthesizer 41 of the singing period 40 (step 280).

Subsequently, the video-acoustic film-synthesized data synthesized by the video-caption synthesizing unit 41 is encoded through the MPEG encoder of the multimedia display apparatus 10 (step 290).

If an external storage medium is installed in the main body 10a of the multimedia display apparatus 10 and the USB storage device 32 is selected as the external storage medium, the video recording unit 22 installed in the main body 10a. ON to store the video-acoustic film composite data in the USB storage device 32 (steps 310 and 321).

In addition, the on-screen switching unit 34 installed on one side of the main body 10a is turned on to output the video acoustic subtitle composite data stored in the USB storage device 32 through the image display unit 14 and the speaker 27. (Step 330).

Subsequently, the synthesized audio and video caption data stored in the USB storage device 32 is reproduced (step 340).

In this case, if the previous step 330 is performed in, for example, a karaoke room, the step 340 may also provide a user with a good memory distance, for example, if performed on a TV or a computer (PC) of the user's home.

On the other hand, after performing step 290, the encoded video acoustic subtitle composite data may be displayed on the image display unit 14 of the multimedia display apparatus 10 (step 300).

That is, the step 300 may display the encoded video-acoustic film composite data on the image display unit 14 of the multimedia display apparatus 10 and simultaneously store the video-acoustic film composite data on the USB storage device 32.

If both the USB storage device 32 and the flash memory card 31 are simultaneously selected as the external storage medium in step 310, the video recording unit 22 is turned on to store the image and sound caption composite data in the USB storage device. Both the device 32 and the flash memory card 31 are stored at the same time, and steps 330 and 340 are continued (step 323).

In addition, if only the flash memory card 31 is selected as the external storage medium in step 310, the video recording unit 22 is turned on to store the video-acoustic film composite data in the flash memory card 31. Continue steps 330 and 340 (step 323).

As such, the multimedia display apparatus 10 according to the present invention may have many functions in itself, or may implement a multimedia system by connecting a separate device, for example, a song cycle period 40 or the internet network 53. have.

Therefore, it is possible to implement a variety of multimedia, for example, it is possible to implement a karaoke system, UCC production, video album production, remote video conferencing. In particular, the flash memory card 31 and the USB storage device 32, which are generally widely used portable storage devices, can be used to instantly store and carry contents produced using the multimedia display device 10. The use of the display device can be maximized.
