When a key is input, it is checked accordingly whether there is a remote control request operation signal generated from the key input block 102 (step 504). Here, the user may input a key for requesting a remote control to change the settings of the output image and the output audio in the case where an error occurs in the output image or the output audio of the image reproducing apparatus 100.

As a result of the check in step 504, when there is a remote control request operation signal, the control block 104 uses the communication module included in the communication block 118 to control the remote control terminal device 300 through the Internet communication network 200.

When the control information is transmitted from the remote control terminal apparatus 300 to the image reproducing apparatus 100, the setting of the image reproducing apparatus 100 can be changed, and the case is complicated compared to a preset number of times (eg, three or more operations). If possible), each of the remote control information for the setting change is generated sequentially and transmitted to the video playback device 100, and the video playback device 100 sequentially in accordance with each remote control information received sequentially You can display the settings as you make them.

Therefore, in an embodiment of the present invention, the device information of the image reproducing apparatus is transmitted by connecting to the remote control terminal device according to the remote control request of the image reproducing apparatus, transmitting the output image including the remote controller image, and outputting the output image. By transmitting the remote control information corresponding to the occurrence error through the video reproducing apparatus to change the setting for the occurrence error, it is possible to effectively solve the error occurring in the image reproducing apparatus through the remote control.

After comparing the setting information to generate device optimization control data (ie, device optimization information, remote control command), the device optimization information (remote control command) is transmitted to the video reproducing apparatus 100 (steps 712 and 714). . Such device optimization information may be stored in the remote control information database 304 corresponding to previously stored device information. Here, the device optimization information may be generated according to the device optimization condition input of the manager in charge of the remote control terminal device 300.

Next, in the control block 104 of the video reproducing apparatus 100, the output video, the output audio, etc. in accordance with the device optimization information (remote control command) from the remote control terminal device 300 received through the communication block 118. The settings for the AV environment of the user are changed (step 716). This setting change process may be displayed through the signal processing block 112 as necessary.

As an example, as shown in FIG. 8A, the menu screen c ′ is sequentially displayed through a remote control command corresponding to the remote controller in the output image C according to the device optimization information transmitted from the remote control terminal device 300. As shown in FIG. 8B, it can be seen that the configuration change of the output image of the image reproducing apparatus 100 such as the detailed menu screen c '' can be performed. As shown in FIG. 4, it can be seen that the contents of the setting change are displayed through the equalizer screen d for the voice output, and the voice of the optimum environment can be output from the speaker d 'through the setting change.

On the other hand, the image reproducing apparatus 100 checks whether the image reproduction is requested (step 718), and if the image reproduction is requested, the image reproduction apparatus 100 performs image reproduction with the changed settings for the image output and the audio output (step 720).

Meanwhile, in another embodiment of the present invention, the device optimization information is described as being transmitted at one time. However, when the setting change of the output image, the output audio, etc. of the image reproducing apparatus 100 is simple compared to the preset number of times (for example, 1). To two or more operations), the device optimization information including all of these setting changes is transmitted from the remote control terminal device 300 to the video reproducing apparatus 100 to change the setting of the video reproducing apparatus 100. In the case of a complicated comparison with a preset number of times (for example, when three or more operations are possible), each device optimization information about a setting change is sequentially generated and sequentially transmitted to the image reproducing apparatus 100, and the image is sequentially transmitted. The playback apparatus 100 sequentially changes the settings according to the device optimization information received sequentially, and at the same time, Can be displayed.

Therefore, according to another embodiment of the present invention, when device optimization control according to the AV environment of the image reproducing apparatus is requested, device optimization information corresponding to the AV environment corresponding to the device information is generated, and the image reproducing apparatus is used by using the device optimization information. By remotely controlling device optimization according to the AV environment, device-specific optimization can be effectively performed according to the AV environment.

In the foregoing description, various embodiments of the present invention have been described and described. However, the present invention is not necessarily limited thereto, and a person having ordinary skill in the art to which the present invention pertains can make various changes without departing from the technical spirit of the present invention. It will be readily appreciated that branch substitutions, modifications and variations are possible.
