Video data packet priority setting method and device

The present invention provides a video packet priority setting method, comprising: carrying-definition video encoding apparatus receives transmission priority management server or fluency priority signaling demand video, video-on-demand image is performed SVC encoder and the video data packets marked with priority label: when the priority resolution requirements jukebox device, each layer of the GOP encoding apparatus airspace I frame video data packets encapsulated into the highest priority tag; jukebox device of claim when fluency priority encoding apparatus each frame of the GOP layer 0 in the spatial packaged as video data packets are marked with the highest priority; the video data packets encapsulated into IP packets, the priority tag provided in the IP packet header to the IP layer the network apparatus can perform scheduling video packet forwarding according to the priority tag. Means the same concept of the present invention further provides. The present invention reduces the burden of network devices, enhance the user experience.
