At least one processor 330 may check the location and size of the first content on the execution screen of the application based on the calculated relative coordinates of the first content. Since the location where the first content is reproduced is calculated in real time based on the marker displayed on the execution screen of the application, the execution screen of the application may change due to a user input or a designated event while the first content is being reproduced on the execution screen. Even if it is changed, the reproduction position of the first content may also be naturally changed.

Illustratively, the at least one processor 330 converts at least one of the address information and the location information into a 1-dimensional barcode (eg, a universal product code (UPC), a European article number (EAN), or Code 128) or a 2-dimensional barcode. The marker may be generated by converting into a barcode (eg, QR code (quick response code), data matrix code, PDF417, data glyphs, or m-code) form. According to various embodiments, at least one processor 330 may digitally sign the address information or the location information with a user's private key and generate the digital signature data together as the marker. . The electronic signature data included in the marker may be used to verify authenticity of a subject who creates (or transmits) the first content or the marker.

In one embodiment, at least one processor 330 may encode the generated marker by inserting it into the position of the determined marker. For example, at least one processor 330 may encode the marker at the determined position in a first frame among a plurality of frames included in the first content. For another example, at least one processor 330 may encode the marker at the determined position of the entire frame included in the first content. According to various embodiments of the present disclosure, at least one processor 330 performs alpha blending in a process of encoding markers in the first content so that the markers encoded in the first content are minimally visible to the user's eyes. At least one image processing method of blending operation or steganography may be applied.

In one embodiment, at least one processor 330 may determine that the first application is in a foreground process. The foreground state may refer to a state in which an execution screen of an application being executed is exposed on the display 320 . According to various embodiments of the present disclosure, the at least one processor 330 determines whether an automatic playback function for moving image type content is set for the first application identified as being in the foreground state, and determines whether the automatic playback function is set. A process for automatically playing the first content may be performed only for the set application.

In one embodiment, at least one processor 330 may capture an execution screen of the first application and detect a marker associated with the first content from the captured image. The marker may include information for automatically reproducing the first content. According to various embodiments of the present disclosure, the at least one processor 330 may capture the execution screen of the first application at every designated time or upon detecting a designated event (eg, change of the execution screen or reception of a user input).

In an embodiment, the at least one processor 330 may determine that the first content should be automatically played on the execution screen of the first application based on the detected marker. For example, if at least one processor 330 confirms that the address information obtained from the marker includes data in a designated format (eg, data in a network url format), the first content is automatically played back. can judge

In one embodiment, if the at least one processor 330 determines that the first content is an automatic playback target, at least one of address information where the first content is stored or information about a location where the first content is to be played is checked from the marker. can The address information is a network address accessible by the electronic device 200 or one or more external electronic devices, and may include a url address of the first content stored by an external server.

According to an embodiment, at least one processor 330 may determine a play area to display the first content within the execution screen on the display 320 based on the location information. For example, at least one processor 330 calculates coordinates within the execution screen where the first content is to be reproduced and a size of the first content based on the location information, and based on the calculation result, the first content It is possible to check the reproduction area of the content. For another example, at least one processor 330 may identify the reproduction area of the first content based on image segmentation of the execution screen. In this case, at least one processor 330 performs image analysis on the captured image of the execution screen to detect a boundary between a content area where the frame image of the first content is displayed and a background area surrounding the frame image. can At least one processor 330 may identify a reproduction area of the first content based on the detected boundary.

When the marker is detected as a result of the check, at least one processor 330 recalculates the coordinates and size of the first content to be reproduced based on the location information obtained from the marker, and based on the calculation result, the processor 330 recalculates the coordinates and size of the first content. 1 You can adjust the playback area of the content. Since the playback area of the first content is calculated in real time based on markers detected on the execution screen of the first application rather than a fixed location, the at least one processor 330 controls the first application in response to a change in the execution screen. By adjusting the reproduction area of the first content, the automatic reproduction of the first content may be naturally continued. As a result of the check, when it is confirmed that the marker is no longer detected from the execution screen, at least one processor 330 may stop the automatic reproduction of the first content.
