Storage system support for continuous-media applications. 1. Requirements and single-disk issues

P. Halvorsen, C. Griwodz, V. Goebel, K. Lund, T. Plagemann, J. Walpole
2004 IEEE Distributed Systems Online  
A multimedia storage system plays a vital role for the performance and scalability of multimedia servers.  ...  To handle the server load imposed by increased user access to on-demand multimedia streaming applications, new storage system solutions are needed.  ...  In applications playing out continuous media streams, for example, each task requires periodic operations that give a certain data amount at each time interval.  ...

Using Temporal Semantics for Live Media Stream Queries [chapter]

Bin Liu, Amarnath Gupta, Ramesh Jain
2006 Lecture Notes in Computer Science  
We investigate the modeling issues and introduce the query processing techniques of a live media stream management system (MedSMan), including media capturing, automatic feature generating, declaration  ...  We address the problem of evaluating continuous queries on media streams produced by media sources such as webcams and microphones.  ...  Due to the heterogeneity of media streams and different application needs, it is desirable for a querying system to be extendable to user-defined operators, i.e., the system allows users to design and  ...

2003 Proceedings of the 13th international workshop on Network and operating systems support for digital audio and video - NOSSDAV '03  
Storing "live" continuous media (such as TV or radio content) adds to the complexity in that this content has no well defined start or end and is therefore cumbersome to deal with.  ...  This approach also allows Spectrum to easily apply time based policies which are basic building blocks required to deal with the storage of live continuous media, to content.  ...  ¢ In this paper we've focused on content management for continuous media objects.  ...
