A live broadcast interaction method, a live broadcast system, an electronic device and a storage medium. The live broadcast interaction method is applied to the live broadcast system, and the live broadcast system comprises an anchor terminal, an audience terminal, and a server. The live broadcast interaction method comprises: an anchor terminal collects contour information and a live broadcast video, encodes the contour information to a network extraction layer of a video code stream, encodes the live broadcast video to a video encoding layer of the video code stream, and uploads the encoded video code stream to a server; the server sends the encoded video code stream to an audience terminal; the anchor terminal and/or the audience terminal further obtains a trigger instruction generated by the server, and obtains corresponding special effect information based on the trigger instruction; and the anchor terminal and/or the audience terminal decodes the human body contour information and the live broadcast video from the encoded video code stream, and renders the special effect information to the live broadcast video based on the contour information. According to the live broadcast interaction method, the interestingness of connection interaction can be enhanced, so that the live broadcast content is richer, and the interactivity is improved.
