Handling audio and video streams in a distributed environment

Alan Jones, Andrew Hopper
1993 ACM SIGOPS Operating Systems Review  
Handling audio and video in a digital environment requires timely delivery of data. This paper describes the principles adopted in the design of the Pandora networked multi-media system.  ...  They attempt to give the user the best possible service while dealing with error and overload conditions. Pandora uses a sub-system to handle the multi-media peripherals.  ...  The audio streams have proved to be quite robust in the face of these changes in the network environment.  ...

Streaming with causality

Cezar Pleşca, Romulus Grigoraş, Philippe Quéinnec, Gérard Padiou
2005 Proceedings of the 13th annual ACM international conference on Multimedia - MULTIMEDIA '05  
Further, this paper proposes a novel approach for handling causality in multimedia and shows that it can perform better than ∆-causality, usually considered the best solution.  ...  We support this comparison by producing video results for a live streaming scenario on an experimental platform.  ...  However, this is more appropriate for distributed environments or games rather than for interactive audio/video streaming.  ...

Media synchronisation an distributed multimedia systems

Bastian, Lenders
1994 Proceedings of IEEE International Conference on Multimedia Computing and Systems MMCS-94  
This research can be extended in many ways, particularly the actions to be taken when a synchronisation error occurs requires further work.  ...  These actions must be related to the synchronisation event that fails and not to the global presentation.  ...  The distributed architecture described in Section 5.3 provides a common interface that allows applications to control multimedia presentations in distributed environments.  ...

Videoconferencing over packet-based networks

M.H. Willebeek-LeMair, Zon-Yin Shae
1997 IEEE Journal on Selected Areas in Communications  
Furthermore, MMT audio and video streams are susceptible to congestion and packet loss in the shared media packet-based environment, while H.320 streams use dedicated connections.  ...  In particular, MMT is a distributed solution, while H.320 is centralized. The use of multicast and a novel video-mixing technique to facilitate the distributed solution are presented.  ...  We then present an efficient way of handling the mixing of multiple audio streams and multiple video streams within each end station.  ...

Specification of multiparty audio and video interaction based on the Reference Model of Open Distributed Processing

Valérie Gay, Peter Leydekkers, Robert Huis in 't Veld
1995 Computer networks and ISDN systems  
This paper uses the viewpoint languages to specify multiparty audio/video exchange in distributed systems.  ...  We take this concept as a basis for multiparty audio and video flow exchanges, and we provide five ODP viewpoint specifications, each emphasising a particular concern.  ...  The goal of this paper is to show how RM-ODP can be used to specify audio/video exchange between users in a distributed environment.  ...
