Abstract

This paper presents an innovative distance learning system named IVA (Interactive Video and Audio) which allows users to access video content, from any electronic device with enough processing capability and resources, aiming an ubiquitous application (anytime and anywhere) through synchronous or asynchronous communication. The paper raises and discusses real issues about multipoint multimedia transmission, taking into account adaptation to differnt devices and different networks. The paper also discusses the implemented solutions to overcome the faced problems. The paper's main focus is on live video transmission to many heterogeneous receivers, as this is the application which demands most resources from devices and network.
