Research into high quality media streaming is regarded as an important area of information technology with the rapid development of network technology and digital A/V home appliances. However, a scheme that can flexibly deal with extreme network dynamics is required to realize high quality media streaming service because the modern internet is designed for best effort services. In this paper, we design...
Media streaming over unreliable networks such as the Internet is growing in popularity, but presents unique challenges when trying to get the user experience to be on par with classical mediums such as cable television. These networks have variable network conditions which not only vary between a set of points in the network, but also change over time. In this paper, we present a rate-distortion (R-D)...
In this paper, we propose a scheme to apply network coding to heterogeneous peer-to-peer media streaming systems. As most peers in a peer-to-peer media streaming system are individual computers connected to the Internet through access links with heterogeneous link capacities, it is desirable to design an adaptive scheme to make efficient use of the bandwidth of the access links. We propose an adaptive...
Multiple description coding (MDC) has been widely used in media streaming to address the bandwidth heterogeneity issue. That is, the video source encodes data into multiple descriptions. At the receiver end, the streaming quality is proportional to the number of descriptions received. In this paper, we investigate how to assign bandwidth for descriptions in order to make full use of available network...
Delivering live media content over best-effort Internet is a challenging task due to a number of factors such as packet loss, delay, and bandwidth fluctuation. As a result, many approaches have been proposed ranging from auto repeat request-typed solutions, forward error correcting code to routing and scheduling protocols and network architecture design. Multiple path streaming is an important solution...
Motivated by the application of streaming multimedia to heterogeneous clients, in this paper we examine the problem of distributing layered content in a network. The source content is represented by multiple description layers that provide incremental refinement; a layer is useful only when all previous layers have been received. For such layered content, a distribution method based on linear network...
Media content distribution constitutes a growing share of the services on the Internet. Two distinct distribution approaches used today are layered coding (LC) and multiple description coding (MDC). Current wireless connection technologies, e.g. Wimax, have properties which make them unsuitable for media distribution using traditional approaches. In particular, the asymmetric relationship between...
