چکیده

By constructing a model which takes into account the frame dependence of multimedia streams, we analyze the performance of different packet-dropping mechanisms and find that scalable video combined with the priority dropping mechanism can bring higher throughput, lower delay and lower delay jitter. We also find the optimum system parameters for multimedia transmission. This study is important for achieving better performance for video transmission over IP networks.

Implementing Congestion Avoidance for Network Transmission of Scalable Video Coding

In this paper we propose a congestion avoidance mechanism for the delivery of scalable video streams over IP networks. Different packets from different video layers are treated with different dropping priorities and are dropped by routers before the network experiences congestion conditions. This mechanism can largely protect higher priority traffic whilst providing bounded video quality guaran...

Priority Dropping for Scalable Video

For H.264/SVC, different layers or frames have different order of precedence according to their importance on video quality and the decoding process. Network should provide more protection for high priority layers or frames when SVC stream is transmitted over IP network. This paper proposes an active queue management algorithm based on priority dropping and PID algorithm, called PID_PD, which f...

TSFD: Two Stage Frame Dropping for Scalable Video Transmission over Data Networks

Scalable video transmission is used to adjust the rate of video depending on the level of network congestion. Previous studies on scalable video transmission of MPEG over ATM ABR service required major changes in the network protocols, and did not provide methods to determine the ABR connection parameters. In this paper, we propose a new scalable video transmission scheme which does not require...

Priority Ordering and Packetization for Scalable Video Multicast with Network Coding

The integration of scalable video representation and network coding (NC) offers an excellent solution to robust and flexible video multicast over IP networks. In this work, we examine one critical component in this system, i.e. video priority ordering and packetization at the source of the multicast tree. First, a GOP-adaptive layer-based packet priority ordering algorithm is proposed to allow ...

MPEG-4 FGS video streaming with constant-quality rate control and differentiated forwarding

Streaming video over IP is studied by integrating the error resilient scalable source codec with constant quality rate adaptation and prioritized network transmission. The scalable codec is based on the standardized ISO/IEC MPEG-4 fine granular scalable (FGS) coding scheme, which allows arbitrary truncation according to the given rate budget. To maximize the end-to-end visual quality, constant ...
