In operation S600, when the advertisement contents are reproduced in the digital signage 300, the digital signage control apparatus 200 displays the full screen of the digital signage 300 according to a predetermined time interval or a time interval that is variably changed , A PIP screen, or a combination of these, may be randomly changed to reproduce the advertisement content whose advertisement text size is adjusted.

When the advertisement content is reproduced in the digital signage 300 in operation S600, the digital signage control apparatus 200 displays the screen of the digital signage 300 as a screen for a near user and a screen for a remote user And reproduce the advertisement contents whose advertisement text size is adjusted on each screen, so that the local users within the reference distance and the remote users outside the reference distance can check the advertisement contents on different screens.

In step S600, the digital signage control apparatus 200 may reproduce the advertisement contents in the digital signage 300. The digital signage control apparatus 200 may include the human movement, illumination, temperature, humidity, After the situation recognition information is measured and confirmed (S800), the resolution and brightness of the advertisement content reproduced through the digital signage 300 are automatically adjusted based on the context recognition information (S900). In operation S900, the digital signage control apparatus 200 may perform on / off control of the digital signage 300 based on human motion detection around the digital signage 300. [

If the resolution and brightness are adjusted in step S900, the digital signage control apparatus 200 outputs the advertisement content whose resolution and brightness are adjusted to the digital signage 300 (S1000) The advertisement contents whose resolution and brightness have been adjusted are reproduced (S1100). Accordingly, the near and far users can confirm the advertisement content whose resolution and brightness are adjusted through the digital signage 300 (S1200).

At this time, on-off control, resolution and brightness control of the digital signage 300 based on the context information of the steps S800 to S1200 may not be used depending on the usage environment of the digital signage 300. [

As described above, the present invention allows the short distance users who are close to the digital signage to check the advertisement contents whose size is adjusted to a small size through the PIP screen, and the remote users to check the advertisement contents whose size of the phrase is greatly adjusted through the full screen Therefore, users who are located in the vicinity of digital signage can be interested and can maximize advertisement exposure.

In addition, since a screen including a full screen of digital signage, a PIP screen, or a combination thereof is randomly changed at predetermined time intervals or at variable time intervals, the advertisement contents whose size is adjusted is reproduced, And thus can be performed variously in a variety of ways. Thus, unlike existing advertisements, the concentration of users on the advertisement contents can be greatly improved, thereby enhancing the advertisement efficiency.

Further, the screen of the digital signage in which the advertisement contents are reproduced is divided into a plurality of screens, the size of the phrase is small and the detailed information is reproduced at the bottom, and the size of the phrase is large and the feature information is reproduced at the top, All of the users in the ad can see the content naturally.

In addition, on / off, resolution and brightness can be automatically adjusted together with the phrase size of the advertisement contents based on various context recognition information around the digital signage, thereby minimizing power consumption and reducing unnecessary power consumption.
