Abstract

A digital signage including a memory; a display; and a controller configured to display content on the display, capture a plurality of images of the displaced content, store the plurality of captured images in the memory, and display the stored images on the display in response to an error event signal.

Claims

1. A digital signage comprising:

a memory configured to store at least a first advertisement schedule and a second advertisement schedule;

a display configured to display first advertisement content at the stored first advertisement schedule and display second advertisement content at the stored second advertisement schedule; and

a processor configured to;

capture a first image of the displayed first advertisement content and store the first image in the memory,

capture a second image of the displayed second advertisement content and store the second image in the memory, and

in response to a predetermined error event signal indicating an error has occurred in displaying advertisement content, display the first image on the display when a time of the error is within the first advertisement schedule, and display the second image on the display when the time of the error is within the second advertisement schedule,

wherein the error event signal is a signal which includes information on the error among response signals of error checking signals sent by the processor.

2. The digital signage according to claim 1, wherein the error event signal includes an error in displaying the content on the display.

3. The digital signage according to claim 1, wherein the processor is further configured to:

receive the content to be displayed from an external server, and

wherein the error event signal includes an error in receiving the content from the server.

4. The digital signage according to claim 1, wherein the content comprises sales content.

5. The digital signage according to claim 1, wherein the processor is further configured to:

continuously display the stored images in a looping manner.

6. The digital signage according to claim 1, wherein the processor is further configured to:

in response to the displayed content including character information, capture an image including the character information, store the captured image in the memory and display the stored image on the display.

7. The digital signage according to claim 1, wherein the processor is further configured to:

display an error event indicator corresponding to the error event signal in one region of the captured image.

8. The digital signage according to claim 1, wherein the processor is further configured to:

in response to the error event signal, display text included in at least one of the stored images on the display.

9. The digital signage according to claim 1, wherein the memory is further configured to store a third advertisement schedule, and

wherein the processor is further configured to:

display third advertisement content at the stored third advertisement schedule,

capture a third image of the displayed third advertisement content and store the third image in the memory, and

in response to the predetermined error event signal indicating the error has occurred in displaying the advertisement content, display the third image on the display when the time of error is within the third advertisement schedule.

10. The digital signage according to claim 9, wherein the first advertisement schedule includes a first schedule of time in a first day, the second advertisement schedule includes a second schedule of time in the first day, and the third advertisement schedule includes a third schedule of time in the first day.

11. The digital signage according to claim 1, wherein the processor is further configured to:

display a graphic user interface on the display including capture setting times at which the first image and the second image should be captured, and

wherein the graphic user interface further includes advertisement display times for setting the first advertisement schedule and the second advertisement schedule.

12. The digital signage according to claim 1, wherein the error event signal includes metadata having an errorEvent element including error event information related to at least one of the digital signage and a network,

wherein the metadata includes at least one of a contentInfo element including basic information of content, a contentplayLog element including log information related to content playback, a playerEvent element including event information of a player related to content and a reserved element for other data or future use, and

wherein the errorEvent element includes at least one sub-element related to identifier information of the digital signage in which the error has been generated, information on the time when the error has been generated, information on a cause of the error and location information of the digital signage.
