1. An electronic device, comprising:
a touchscreen display;
a speaker; and
a processor,
wherein the processor is configured to:
obtain a user input to output video data of a first content while outputting audio data of the first content through the speaker; and
based on the user input:
identify a time point that the audio data is output through the speaker;
determine a time point that the video data is to be output through the touchscreen display or an external electronic device by a plurality of delay times calculated at least based on the identified time, wherein the plurality of delay times are determined based on at least one of a position of a previous sync frame closest to a time in which the audio data is output through the speaker, a delay time of at least one video filter applied to the video data, or a video data transmission delay time demanded by the touchscreen display or the external electronic device to output the video data; and
control the touchscreen display or the external electronic device such that the video data is output through the touchscreen display or the external electronic device at the determined time.
