The invention discloses a live broadcast method, device and
system and belongs to the field of network live broadcast. The method comprises the following steps: receiving live broadcast synthesis parameters sent by an anchor
client; receiving at least two live broadcast video streams sent by the anchor
client, wherein the at least two live broadcast video streams are corresponding to respective visual angles; synthesizing the at least two live broadcast video streams into a target live broadcast video
stream according to the live broadcast synthesis parameters; and sending the target live broadcast video
stream to at least one audience
client corresponding to the anchor client. The at least two live broadcast video streams are synthesized into the same live broadcast frame by utilizing the live broadcast synthesis parameters, so that the problems of not high live
broadcast quality and not stable frame in the live broadcast video
stream due to repeated rotation of a camera in the live broadcast process are solved, and the effects that one live broadcast frame has different live broadcast visual angles, the live broadcast frame is more stable, and playability of outdoor live broadcast is improved are achieved.
