Abstract: The present invention discloses a method and device for displaying text and video in two threads. The method comprises: when receiving video message, switching display state of chat interface from sleep state to play state to play the video message on background of the chat interface; in process of playing the video message, responding to user terminal's operation instructions to chat control and/or play control on the chat interface; and at the end of the video message playing, switching the display state of the chat interface from play state to sleep state. The present invention can display text message and video message in two threads on the same operation interface, so that users can get the text message and video message at the same time, and the efficiency of message acquisition can be improved.

Abstract: The present invention discloses a method and system for cutting video using video content. The method comprises: acquiring recorded video produced by user's recording operation; extracting features of recorded audio in the recorded video and judging whether the recorded audio is damaged; and if not, extracting human voice data from the recorded audio which has been filtered out background sound, intercepting video segment corresponding to effective human voice, and displaying the video segment as clip video; and if yes, extracting image feature data of person's mouth shape and human movements in the recorded video after image processing, fitting the image feature data and the human voice data which has been filtered out background sound, and displaying the video segment with the highest fitting degree as clip video.
