Abstract
To-be-commented video data is received by a terminal device, and a video sequence number of the to-be-commented video data is determined, which steps further include comprising, by the video data, a first correlation 2-tuple of a global base sequence number and the video sequence number, in which a sequence number of a live voice in the video data is the global base sequence number, and the video sequence number of the video data is determined according to the global base sequence number; and determining a video sequence number of the to-be-commented video data according to the first correlation 2-tuple. The to-be-commented video data is played, a commentary voice is acquired, and a correspondence between a voice sequence number of the commentary voice and the video sequence number is determined. The correspondence between the voice sequence number and the video sequence number is sent to a video playback end.
