Smart video packet trimming technique over congested networks

In past few years, multimedia traffic is growing and Internet have maximum portion of multimedia traffic. This traffic trend is expected to increase due to multimedia applications. Best effort Internet architecture poses design limitations for multimedia traffic. IPTV like applications require higher bandwidth, low packet loss, low delays and jitter effects to transmit high quality video contents. Packet loss due to limited band width and congestion can negatively impact on Quality of Experience(QoE). Packet trimming based innovative scheme is proposed in this article to deal packet loss and improve QoE. Proposed scheme eliminate the chance of packet loss during congestion. Packet trimming scheme better handle congestion which improve video smoothness, interactivity and frame quality. Test-bed implementation and subsequent analyses shows promising improvement in video Quality of Experience over same Quality of Service.
