TLDR
The authors describe the convergence of a number of existing multimedia toolkits into a common programming infrastructure and argue that the availability and acceptance of the middleware could potentially facilitate and accelerate breakthroughs in multimedia networking.Abstract:
Real-time multimedia streams like audio and video are now integral data types in modern programming environments. Although a great deal of research has investigated effective and efficient programming support for manipulating such streams and although the design of digital media "middleware" is fairly well understood, no widely available or commonly accepted programming model exists within the research community. The authors believe this lack of common practice impedes our collective progress because it prevents disparate research groups from easily leveraging each other's work. They propose a solution to this problem that combines the best features of a number of existing multimedia toolkits-Berkeley's Continuous Media Toolkit, MIT's VuSystem, and the LBL/UCB MBone tools-into a fine-grained, extensible, and high performance toolkit. They describe the convergence of these three toolkits into a common programming infrastructure and argue that the availability and acceptance of the middleware could potentially facilitate and accelerate breakthroughs in multimedia networking.read more

An active service framework and its application to real-time multimedia transcoding
TL;DR: The initial experience indicates that the active services prototype provides a very flexible and programmable platform for intra-network computation that strikes a good balance between the flexibility of the active networks architecture and the practical constraints of incremental deployment in the current Internet.

A reliable multicast framework for light-weight sessions and application level framing
TL;DR: An adaptive algorithm is demonstrated that uses the results of previous loss recovery events to adapt the control parameters used for future loss recovery, and provides good performance over a wide range of underlying topologies.
