The signboard status information processor 221 extracts weather, interest, and time information based on the situational information around the signboard (for example, information about a user around the signboard and environmental information around the signboard). At this time, the degree of interest indicates the degree of interest of the user in the signboard based on the information on the signboard user. For example, the billboard status information processor may use fuzzy logic algorithm to extract information of weather, interest, and time. Here, the fuzzy logic algorithm is an algorithm that divides an ambiguous situation into several approximations when there is no clear boundary value.

The billboard status information processor 221 may receive information on a list of contents through the content list selector 223. For example, the content list may be divided into news (by broadcaster, time zone, breaking news broadcast, etc.), advertising (which may be classified by various items such as cosmetics, home appliances, food, automobiles, industrial products), emergency broadcasts (war, It can be classified according to various situations such as fire and natural disasters), and public service broadcasting (which can be classified according to various public interest fields such as non-smoking and environmental protection).

The billboard status information processor 221 controls to select a desired content from a content list in consideration of weather, interest, time, and the like.

The content image storage unit 222 is connected to the content server 30 to receive the content.

The content list selection unit 223 provides the information matching unit 224 with information about the content selected for each display board.

The content matching unit 224 receives information about the selected content from the service list selection unit 223. The content matching unit receives the corresponding content image from the service image storage unit 222 through matching of the content image corresponding to the selected content information.

The content matching unit 224 outputs contents corresponding to each of the signboards to the image codec 215.

Meanwhile, when an emergency situation or a disaster situation occurs, the content matching unit 224 may provide content related to emergency broadcast or disaster broadcast to an electronic billboard in a corresponding region through administrator control.

The management image display unit 230 displays an image signal output from the image codec. Through the management image display unit 230, the manager may recognize a situation around the signboard. In addition, the management image display unit 230 may display the content provided by each of the billboards and the status information of the billboard.
