Electronic device for playing video and operating method of the same

An electronic device for processing and playing a video transmitted from an input device, the electronic device comprising:

• an input module configured to receive at least one test video from the input device, each test video including a plurality of frames including a first pattern and a second pattern;
• and
• a processor configured to check an output order of each of the plurality of frames included in at least one sampling video generated from performing a processing operation on the at least one test video, based on the first pattern, check whether the at least one sampling video is output normally, based on the second pattern, and
• determine whether an error occurs in at least one of the input device and the electronic device, based on the output order and whether the at least one sampling video is output normally.
