Claim 9:
10. A computing system of displaying comments relative to video frames, comprising:
at least one processor; and
at least one memory communicatively coupled to the at least one processor and storing instructions that upon execution by the at least one processor cause the computing system to:
receive a frame of a video;
receive bullet screen data comprising a plurality of comments associated with the frame;
receive a mask frame data segment comprised in a previously generated mask frame file and corresponding to the frame, wherein the mask frame data segment is generated based on a main area of the frame by converting the main area into contour data, compressing pixel resolution of the contour data to a predetermined pixel resolution range, compressing color bit depth of the contour data to a predetermined binary bit, performing an edge feather processing on the contour data, and generating the mask frame data segment based on the contour data;
determine a mask area based on the received mask frame data segment, wherein the mask area corresponds to the main area of the frame, and wherein the main area of the frame is selected from at least one of a landscape area range, an architectural area range, an artwork area range, a text area range, a character, or an animal in the frame; and
display the plurality of comments scrolling across the frame in areas other than the mask area.
