Electronic device, method, and non-transitory computer-readable storage media for displaying other video corresponding to video displayed on external electronic device

A method of an electronic device, the method comprising:

• obtaining, from an external electronic device using communication circuitry, first information for displaying a video to be played through a display of the external electronic device;
• identifying, based on the first information, at least one part of the video expandable by out-painting frames included in the at least one part of the video;
• identifying a remaining time for the electronic device to out-paint the frames included in the at least one part of the video, to a time at which the frames included in the at least one part of the video are played through the display, through the display of the external electronic device;
• determining, based on the remaining time, a size of expanded frames to be out-painted from the frames included in the at least one part;
• generating, during the remaining time, the expanded frames by out-painting the frames;
• and
• displaying, using a projection assembly, the expanded frames including a black area partially overlapping the video displayed through the display of the external electronic device, at a time when the at least one part including the frames is displayed.

A non-transitory computer readable storage medium storing one or more programs including instructions, that when executed by at least one processor of an electronic device, cause the electronic device to:

• obtain, from an external electronic device using communication circuitry, first information for displaying a video to be played through a display of the external electronic device,
• identify, based on the first information, at least one part of the video expandable by out-painting frames included in the at least one part of the video,
• identify a remaining time for the electronic device to out-paint the frames included in the at least one part of the video, to a time at which the frames included in the at least one part of the video are played through the display, through the display of the external electronic device,
• determine, based on the remaining time, a size of expanded frames to be out-painted from the frames included in the at least one part,
• generate, during the remaining time, the expanded frames by out-painting the frames, and
• display, using a projection assembly, the expanded frames including a black area partially overlapping the video displayed through the display of the external electronic device, at a time when the at least one part including the frames is displayed.
