Transparent protocol translation for streaming

2007 Proceedings of the 15th international conference on Multimedia - MULTIMEDIA '07  
This is beneficial for the server side that scales to a higher load when it doesn't have to deal with TCP.  ...  The transport of streaming media data over TCP is hindered by TCP's probing behavior that results in the rapid reduction and slow recovery of the packet rates.  ...  In the experiment, we compare a normal web-server streaming video with a RTP server (komssys) to a client by encapsulating the video data in HTTP packets on a IXP network card close to the video server  ...

A Priority Selected Cache Algorithm for Video Relay in Streaming Applications

Shin-Hung Chang, Ray-I Chang, Jan-Ming Ho, Yen-Jen Oyang
2007 IEEE transactions on broadcasting  
To solve this problem, we proposed a novel video cache algorithm, called the Optimal Cache (OC) algorithm, for a relay video proxy.  ...  The PSC algorithm reduces the decoding errors caused by packet loss, improves error recovery, and provides QoS-guaranteed video playback.  ...  The PSC algorithm effectively selects the maximum amount of high priority frame data and caches it in the relay video proxy so as to minimize packet loss and improve error recovery.  ...

Another proposal based on the use of a proxy is shown in [12] , which presents a proxy-based solution for adapting the scalable video streams at the edge of a wireless network.  ...  Talking about different video transmission techniques, [13] presents a system framework for network compression of interactive multi-view streaming video with path diversity.  ...  The losses level as well as the average delay of section 2 can be seen in Fig. 11a . There are two main loss areas, one with 40% of packet losses and another with a complete loss of connectivity.  ...

Exploiting the fair share to smoothly transport layered encoded video into proxy caches

Michael Zink, Carsten Griwodz, Jens Schmitt, Ralf Steinmetz, Martin G. Kienzle, Prashant J. Shenoy
2001 Multimedia Computing and Networking 2002  
Hierarchically layered video encoding is particularly well suited to deal with adaptiveness and heterogeneity support for video streaming.  ...  Moreover, a design for the integration of fair share claiming in streaming applications which are supported by caching is devised.  ...  In addition it uses slow-start at start-up and for loss recovery. Transmitting a layer encoded video with the maximum rate that TFRC would allow does not always make sense.  ...

2008 Proceedings of the 18th International Workshop on Network and Operating Systems Support for Digital Audio and Video - NOSSDAV '08  
For every client that accesses a video with HTTP, the proxy performs transparent translation of the stream.  ...  Comparing HTTP-streaming from a web-server and RTP/UDP-streaming from a video server shows that, in case of some loss, our solution using UDP from the server and a proxy that translates to TCP delivers  ...

Video delivery technologies for large-scale deployment of multimedia applications

K.A. Hua, M.A. Tantaoui, W. Tavanapong
2004 Proceedings of the IEEE  
In this paper, we describe three complementary research approaches: server transmission schemes using multicast, streaming strategies with Application Layer Multicast, and proxy caching techniques.  ...  Deployment of a large-scale multimedia streaming application requires an enormous amount of server and network resources.  ...  Instead of using client storage, Proxy-based Asynchronous Multicast [20] allocates proxy cache space for its clients to store and forward data to the new clients requesting the same video at a later  ...

Translating scalable video streams from wide‐area to access networks

Carsten Griwodz, Steffen Fiksdal, Pål Halvorsen
2004 Campus-Wide Information Systems  
In this paper, we consider a proxy server to translate the traffic and two straight-forward approaches for the translation of a layered video stream transmission from the TCP-friendly transport protocol  ...  Transmitting video over UDP has been considered advantageous because it allows for discarding of packets in favor of retransmissions, and sender-controlled timing.  ...  Furthermore, the proxy could filter packets based on a jitter threshold.  ...
