2. Description of the Related Art [0002] In general, optical disk recording / reproducing techniques are gradually developed, and various disk media and reproducing apparatuses thereof are diversified, and their functions are becoming complicated.

For example, in the case of a general DVD player, audio can be recorded and played back on 8 channels, and a language of two or more languages can be recorded on a movie such as a movie. In addition, It is possible to freely select and view an image of a desired angle at the time of reproduction, and even when the menu contents are displayed on the screen, the captions can be recorded and reproduced in languages of two or more languages.

And other functions that the user can select, such as a sub-picture that composes the screen of the auxiliary image in addition to the other functions, that is, the screen displayed in the main image.

Therefore, the user can select the image, the subtitle, and the channel of the desired angle at the time of reproduction to enjoy the optimum image, voice and music from the user's point of view.

However, although the conventional art has various functions as described above, a basic environment is set.

For example, when an environment other than the basic environment is desired, since it is set to Angle 1 and channel 1 (Korean), there is a disadvantage that it is necessary to change to a desired environment before and during reproduction at the time of reproduction. If the DVD player can also play CDs, the reproduction environment according to the type of media (CD, DVD) must also be changed.

Hereinafter, a method of setting a playback environment of a DVD according to the related art will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a DVD reproducing apparatus according to the prior art.

The conventional technique includes a key input unit 1 for inputting various functions of a DVD by a user, a control unit 2 for controlling the DVD according to the output of the key input unit 1, A servo section 4 for driving and moving the reading section 1 in accordance with a control signal of the control section 2; An amplifying unit 5 for amplifying the bit stream of the mounting unit 1 and feeding back the amplified bit stream to the servo unit 4, And a decoder unit 7 for decoding and outputting a video signal of the signal processing unit 6 in accordance with a control signal of the control unit 2. [

When the user inputs a playback command through the key input unit 1 to the DVD, the control unit 2 controls the entire system.

That is, the control unit 2 inputs a control signal to the servo unit 4 and reads the bit stream of the optical disk through the reading unit 3. [

The bit stream is amplified by the amplifier 5 and fed back to the servo 4.

At this time, the servo unit 4 performs tracking, focusing, and spindle motor control of the optical pickup to control the information to be reproduced optimally from the disc.

The bit stream output from the amplifying unit 5 is processed into a video signal and a video signal in the signal processor 6.

The video signal is a signal having a basic environment set by the control unit 2, that is, a frontal angle and a Korean channel.

The video signal is decoded by the decoder unit 7 to implement an image.

As described above, the conventional DVD reproducing method has a problem that it can not improve the utilization of various functions of the DVD because there is no option for setting the reproducing environment.
