Then, embodiments will be described so that those skilled in the art can easily implement the present invention.

1 is a block diagram of an audio reproduction apparatus having a display function according to an embodiment of the present invention.

As shown in FIG. 1, an audio reproducing apparatus having a display function according to an embodiment of the present invention includes a power supply unit 5 for supplying power for driving an audio reproducing apparatus, and a key operation unit 10 for outputting a key manipulation signal of a user. ), A CD drive unit 20 for driving the inserted compact disc, a tape drive unit 30 for driving the inserted tape, a memory 40 for storing video image data, a display window 60 for displaying the video image data, and The control unit 50 is included.

The memory 40 stores at least one video image having one theme, and the key operation unit 10 provides the control unit 50 with a key operation signal for controlling the audio reproduction device according to a user's operation. In this case, the memory 40 may be a memory installed in the initial production process of the audio reproducing apparatus in consideration of economical aspects.

The controller 50 controls the CD drive unit 20 or the tape drive unit 30 to output audio sound through a speaker (not shown) according to the key operation signal of the key operation unit. The display window 60 displays numerical or character information including the current playback time of the audio sound (CD sound or tape sound) or the remaining time of playback, component information currently driven, and the like. In this case, when a control signal for outputting a moving image is input by the user as a key manipulation signal, the moving image stored in the memory 40 is read and displayed on the display window 60.

The display window 60 generally includes an LCD panel, and receives moving image data stored in the memory 60 from the controller 50 and displays the same. The sharpness of the moving image displayed by the LCD panel increases as the area of the screen is larger and the number of pixels is larger, so that as the production cost allows, the sharper and larger screen can be displayed.

2 is a block diagram of an audio playback apparatus having a display function according to another embodiment of the present invention.

2 further includes a PC interface unit 700 for data connection with a computer, in addition to the components shown in FIG. In this case, the memory 400 is a memory capable of reading / writing (read / write) to store moving image data input through the PC interface unit 700.

As shown in FIG. 2, the controller 50 reads out the corresponding video image data stored in the memory 400 capable of reading / writing according to a user's key manipulation and displays the moving image data on the display window 60.

In addition, the controller 50 receives a moving image through a PC interface unit 700 connected to a computer 810 capable of network connection, and upgrades or replaces moving image image data stored in the memory 400.

At this time, the computer 810 is connected to a client-side Internet Service Provider (ISP) 820, the Internet 830, a server-side ISP 840, and a server 850 that provides video image data. The data is downloaded and stored in the memory 400 that can be read / write via the PC interface 700 and the controller 50.

3 is a view for showing a moving image having a theme stored in the memory in accordance with the present invention.

Referring to FIG. 3, a theme representing a frog's movement consists of a total of 54 frame screens and is stored in the memory 40 and 400.

In general, since the minimum frame that the human eye can recognize as a moving picture is 16 frames per second, the controller 50 reads an image of 16 frames per second from the memory 40 and 400 and displays the image on the display window.

At this time, the image data stored in the memory 40, 400 is limited in size, so that in order to display the image data in real time, the controller is connected to a theme while the audio sound is played according to a predefined format. The image data is read out from the memory and displayed on the display window.

For example, the 15th frame and the 16th frame can be repeated because only the frog's mouth shape is changed, and the 15th and 18th frames can be repeated because the eyes of the frog are moving. Frames 29 th frame can be repeated because the frog is swimming underwater.

By using this method, an image of a limited frame can be displayed according to a time when an audio sound is reproduced according to a user's setting.

Hereinafter, a video display method using an audio reproducing apparatus having a video display function according to an embodiment of the present invention will be described.

4 is a flowchart illustrating a video display method according to an embodiment of the present invention.

As shown in FIG. 4, first, whether driving power for driving the audio reproducing apparatus is applied or not (step S10), and when driving power is applied, displaying a moving image image stored in the memory 40 or 400. It is checked whether or not the operation signal for the input is input (step S20).

If an operation signal for displaying a moving image is not input in step S20, information including text data or numeric data according to the normal playback mode is displayed on the display window 60 of the audio playback apparatus (step S25).

When an operation signal for displaying a moving image is input in step S20, the theme menu of the moving image stored in the memory is displayed on the display window 60 of the audio reproducing apparatus (step S30).

Then, it is checked whether it is selected by the user from the video theme menu displayed on the display window (step S40), and if the video theme menu is not selected by the user, it is set to a preset theme (step S45).

The display speed menu is then displayed on the display window 60 (step S50).

Then, it is checked whether it is selected by the user from the displayed moving picture display speed menu (step S60), and if the moving picture display speed menu is not selected by the user, it is set to the preset display speed (step S65).

The display time menu is then displayed on the display window 60 (step S70).

Then, it is checked whether it is selected by the user from the display time menu displayed on the display window (step S80), and if the moving picture display time menu is not selected by the user, it is set to the preset display time (step S85).

Then, the video of the selected theme is displayed on the display window 60 for the selected time at the selected speed (step S90).

According to the present invention mentioned above, various video images that may induce the user's interest can be displayed through the display window of the audio playback device, so that the user's freeness can be eliminated.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention as set forth in the claims below. It will be appreciated.

As described above, according to the present invention, only numerical or text information is displayed through the display window of the conventional audio reproducing apparatus, thereby providing various attractions and fun while listening to the user's audio or playing other devices instead of giving the user free of charge. can do.

According to the present invention, even if a compact disc or a tape of an audio playback device having a video display function is driven to listen to audio sound, the theme of the video image stored in the memory can be selected and displayed for a selected time as long as the driving power is applied. Therefore, the decorative effect can also be obtained.

In addition, according to an audio reproducing apparatus according to another embodiment of the present invention, in order to upgrade or replace a moving image image stored in a memory, the moving image image data is down by connecting to a computer having a network connection such as the Internet. It can be received and stored in memory, so you can enjoy various video images. At this time, if the memory capacity is small, it is obvious that the memory can be replaced with a larger capacity.
