Abstract
Disclosed are a method, an apparatus, and a system for implementing video stream switching. The method can determine switching reference information of a first reference frame trailer packet of a first video stream and switching reference information of a second reference frame trailer packet of a second video stream, when receiving a switching instruction; and switch from the first video stream sent through the target egress port to the second video stream based on the switching reference information of the first switching packet and the switching reference information of the second switching packet. Because locations of data packets sent before and after switching are considered during video stream switching, damage caused by a switching operation to a transmitted video image can be effectively reduced.
