The present invention relates to the field of video transmission, and discloses a method, an apparatus, and a system for forwarding video data. The method includes: receiving and buffering a media stream, resolving the buffered media stream, obtaining Transport Stream (TS) packets in the media stream, and evaluating and identifying a visual sensitivity priority of each TS packet; discarding a TS packet of low visual sensitivity, and re-encapsulating a TS packet of high visual sensitivity into a new media stream; and sending the re-encapsulated new media stream to a user equipment, where the TS packet of high visual sensitivity includes at least a video TS packet that encapsulates an internal coding frame. Through the embodiments of the present invention, a network device is enabled to discard the TS packet of low visual sensitivity in the media stream, which reduces duration of fast channel change, relieves network congestion, and improves transmission efficiency without affecting Quality of Experience (QoE) of a user. |
