Packet scheduling scheme for MPEG video transportation

Packet loss control is an essential issue for video transportation over Internet. Buffer management is a traditional network technique to protecting video data against packet loss. To meet the need of quality of service in MPEG video transportation, a new innovative use of packet scheduling to meet the loss constraints of video communication is proposed. Followed by programming tests concerning establishment of systematic video communications, the packet-scheduling scheme that intra and inter-stream loss requests for video transportation are met was simulated and evaluated using real video data. The simulation experimental results show that the quality of service mechanism can effectively improve the quality of service of MPEG video transportation.
