Apparatus, method, and program for subtitle manage-ment based on artificial intelligence

An artificial intelligence-based subtitle management apparatus comprising:

• a subtitle generation unit configured to acquire content data including video data and audio data from a first user terminal, and to generate first subtitle data synchronized based on time information of the audio data using a subtitle generation model;
• a content provision unit configured to re-synchronize the first subtitle data based on motion information of the video data, and to provide the content data and the first subtitle data to a second user terminal in a matched manner;
• and
• a subtitle modification unit configured to receive a subtitle modification request including modification data from the second user terminal, and to generate second subtitle data by modifying the first subtitle data based on the modification data,
• wherein the video data comprises a plurality of sequentially continuous frames,
• wherein the content provision unit is further configured to:
• classify the plurality of frames into a plurality of groups based on the motion information,
• wherein, when an N-th frame (where N is a positive integer) and an (N+1)-th frame among the plurality of frames include different motion information, the N-th and (N+1)-th frames are classified into different groups;
• and
• wherein the subtitle modification unit is further configured to:
• determine a suitability of the subtitle modification request based on at least one of a matching rate between the modification data and the first subtitle data, and information related to the subtitle modification requester;
• and
• when the suitability exceeds a threshold, modify the first subtitle data to generate the second subtitle data.
