The present invention discloses a video surveillence system and a Forward Error Correction (FEC) method thereof. The method includes: the surveillence front end initiating a session request to the surveillence platform and establishing a session; the surveillence front end performing FEC encoding on a source media code stream, and transferring an FEC code stream obtained through the encoding and the source media code stream to the surveillence platform in a same channel; the surveillence platform splitting received code streams into the source media code stream and the FEC code stream, and if it is determined that a media packet is lost in the source media code stream, recovering the lost media packet in the source media code stream through the FEC code stream. By using the present invention, the problem of network packet loss between the surveillence front end and surveillence platform frequently resulted from the limited uplink bandwidth is solved, and use-cost is reduced. |
