The present invention relates to a CD-TV composite product comprising a compact disc (CD) player and a television (TV) receiver integrally, and is particularly useful for switching a TV mode to a CD mode in a CD-TV composite product. It is about.

The present applicant invents and sells a compact disc song accompaniment device, and also invents and sells a so-called karaoke television receiver. A compact disc song accompaniment device, also known as a CD-OK device, stores more than 2000 song accompaniment and lyrics and about 4000 still images on a single compact disc. Plays back the screen that matches the mood of the lyrics. The karaoke television receiver stores about 400 lyrics, accompaniment data and dozens of graphic image data in a semiconductor memory device and provides CDG-level karaoke.

However, since the CD-OK has no display unit, it is inconvenient to use because it is connected to the external video connection jack of the television receiver through the audio and video output terminals to display the video signal and the audio signal on the CRT and output the audio to the speaker. The karaoke television receiver is integrated with the television, but the number of selectable songs is about one fifth less than that of the CD-OK, and the background image is not varied.

In addition, various types of compact discs such as CD digital audio, CDG, CDV, etc., and their respective players have been commercialized and introduced. Therefore, consumers have to purchase each player each time a single product is released, and there is a difficulty in securing an installation space, and the external connection lines for interconnecting these products are complicated.

Accordingly, in order to solve the above-mentioned problems, a CD-TV composite product in which a CD player and a television are integrated is disclosed. However, since different functions are combined in one product, it is necessary to effectively control the operation of these functions.

Disclosure of Invention An object of the present invention is to provide an operation mode switching device and method for converting a TV mode into a CD mode in accordance with the current device state in a CD-TV composite product in which a CD player and a TV receiver are integrated.

In the operation mode switching apparatus of the CD-TV composite product according to the present invention for achieving the above object, a TV (TV) receiver and a compact disc (CD) player is integrally formed, the TV mode and CD operating as a TV receiver. A CD-TV composite product operable by a user's selection in a CD mode operating as a player, comprising: a TV function key for operating in a TV mode and a CD function key for operating in a CD mode; Mode input means for setting an operation mode of the composite product by inputting a function key; Control means for setting an operation mode of the composite product according to the input by the mode input means, and generating information to be displayed on the mode display means according to the set operation mode; And mode display means for displaying information on the operation mode generated by the control means.

The operation mode switching method of the CD-TV composite product according to the present invention for achieving the above object, the TV (TV) receiver and the compact disc (CD) player is integrally configured, the TV function for operating in the TV mode Operation mode of the CD-TV composite product which can be operated in the TV mode acting as a TV receiver and the CD mode acting as a CD player by input through a key input unit having a key and a CD function key for operating in a CD mode. A switching method comprising: a first step of operating the composite product in a TV mode; A second step of inputting a CD function key through the key input unit; A third step of checking whether there is a disc in the CD player; If there is no disk in the third step, displaying information on the disk on the screen and continuing to perform the operation mode before inputting the CD function key; And if there is a disc in the third step, determining the type of the disc to display information on the current disc type on the screen, switching to the CD mode, and then performing the operation of the input CD function key. It is characterized by including.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a front view of a CD-TV composite product. In Fig. 1, 10 is CRT, 12 is Speaker, 14 is Microphone Jack, 16 is Disk Door, 18 is CD Open / Close Button, 20 is Remote Control Window, 22 is Power Indicator Lamp, 24 is Main Power The button and 26 are the control boxes.

2 shows the arrangement of the keys installed in the control box 26.

The keys are largely divided into a TV control key 28 and a CD control key 30. The TV control key 28 includes a channel up / down key, a sound up / down key, a menu key, a TV / VIDEO key, a mute key, and the like. CD control key 30 includes pitch up / down key, tempo up / down key, confirmation key, reservation key, cancel key, 0-9 number keys, skip key, scorecard, male / female key, background selection key. , Play key, stop key, music selection up / down key, CD on / off key, menu key, and the like.

3 is a block diagram showing the configuration of an operation mode switching device in a CD-TV composite product according to the present invention. 31 is a key input unit, 33 is a mode control unit, 35 is a mode display unit, and 37 is a CD-TV composite product.

CD-TV composite product 35 is composed of a television (TV) receiver and a compact disc (CD) player integrally, the TV mode to operate as a TV receiver and the CD mode to operate as a CD player to operate according to the user's selection Can be.

The key input unit 31 has a TV function key for operating in the TV mode and a CD function key for operating in the CD mode to set the operation mode of the CD-TV composite product 35. This is realized by a control box attached to the product. Examples of TV function keys include channel up / down keys and sound up / down keys. Examples of CD function keys include CD open / close keys, pitch up / down keys, tempo up / down keys, playback keys, and stop keys. Etc.

The mode control unit 33 sets the operation mode of the CD-TV composite product 35 in accordance with the key input by the key input unit 31. If the set mode is the CD mode, it is determined whether or not a disc exists in the CD player and the type of the disc in the CD player, and information to be displayed on the mode display unit 37 is generated according to the determination information.

The mode display unit 37 displays information on the operation mode generated by the mode control unit 33, for example, whether or not there is a disc in the CD player or the type of the disc.

4 is a flowchart illustrating a method of switching an operation mode in a CD-TV composite product according to the present invention.

The CD-TV composite product is always set to the TV mode at the initial power-on state (41). When the CD function key is input to the CD-TV composite product operating in the TV mode (42), it is first checked whether there is a disc in the CD player (43).

If there is no disc in the CD player, an error message is displayed on the screen. Please insert a disc. The operation mode before the function key is input continues (46).

On the other hand, if there is a disc in the CD player, the type of the disc is determined, the mode is switched to the CD mode (44), the current disc type is displayed on the screen, and the operation of the input function key is performed (45).

An example of the operation performed according to the type of disk is as follows.

In the case of a CD digital audio disc, related information such as disc table information is displayed on the screen, and the user can interactively use the remote control while viewing the information displayed on the screen. If the CDG or CD-OK disc is used, when using the song playing function using the CD-OK disc, the background image is provided as a still image recorded in the disc. Can be selected as wallpaper.

On the other hand, when all other keys except the CD open / close key of the CD function keys are operated as described above, when the CD open / close key is input, the open / close function is performed immediately without displaying the screen.

As described above, according to the present invention, when the CD-TV composite product is changed to the CD mode by the user during the operation in the TV mode, the existence of the disc and the type of the disc are checked, thereby minimizing unnecessary operation of the composite product. It can provide convenience.
