The COMODIN System: A CDN-based Platform for Cooperative Media On- Demand on the InterNet
نویسندگان
چکیده
In this paper we present the COMODIN (COoperative Media On-Demand on the InterNet) system, a media on-demand platform for synchronous cooperative work, which is aimed at securely supporting an explicitly-formed cooperative group of distributed users for (i) requesting an archived multimedia session, (ii) sharing the playback, and (iii) collaborating with each other through questioning and, optionally, synchronous audio/video tools. At the server-side, the system is based on an IPmulticast-enabled Content Distribution Network, which consists of a coordinated set of heterogeneous and distributed multimedia servers, whereas, at the clientside, the system centers on Java-based applications and applets which interface the cooperative group of users. Significant applications featured by the COMODIN system encompass Collaborative Learning on-Demand and Distributed Virtual Theaters.

متن کاملEditorial for special issue Internet-based Content Delivery
We are in the midst of an Internet computing revolution. One vision of 21st century computing is that users will access Internet services and ‘‘resource-hungry’’ applications (e.g. gaming, streaming media, video on demand, and voice-over-IP) over lightweight portable devices rather than through some descendant of the traditional desktop PCs. In this context, distributing and processing Internet...
