Internet as a synonyme of the „new media“ not only contains and disseminates information worldwide – like electronic broadcast media , it is also capable of processing information in an interactive manner, since it is computer-based, i.e., its information objects are virtual machines. Thus, the potential of the new media is urging us to reconsider the notion of media. Since we witness that form...

(Technical Report WPI-CS-TR-02-17) Proceedings of the Packet Video Workshop Nantes, France April 2003 http://www.cs.wpi.edu/~claypool/papers/h2h/ The Hungry Wolf Bandwidth Requirements for Video • Streaming media growing – 350,000 hours of online video broadcast ’01 • Voice is 32-64 Kbps, but video has range of data rates – Videoconference 0.1 Mbps (H.261, MPEG-4) – VCR 1.2 Mbps (MPEG-1) – Broa...

This paper addresses recent progress in speaker-independent, large vocabulary, continuous speech recognition, which has opened up a wide range of near and mid-term applications. One rapidly expanding application area is the processing of broadcast audio for information access. At LIMSI, broadcast news transcription systems have been developed for English, French, German, Mandarin and Portuguese...

We introduce the Fortunate Artists Media Empire (FAME) problem domain to study approaches for solving key challenges in distributed planning such as dynamic environments, dynamic goals, uncertainty of actions and scalability. FAME is an artificial problem domain that allows us to focus on key domain-independent research issues. The FAME problem domain is focused on broadcast quality monitoring ...

This essay explores the media frame-changing process in the news coverage of the 1999 Columbine shootings, clarifying the news discourse focus on Columbine’s national importance. The study applies the van Dijk/Bell scheme of media analysis to 683 news articles from print and broadcast media published within 30 days following the incident. Insight is offered into the thematic content of the Colu...

When using an on-demand media streaming system on top of a network with Multicast support, it is sometimes more efficient to use broadcast to distribute popular content, especially when client demand is high. There has been a lot of research in broadcasting on-demand content to multiple, asynchronous receivers. In this paper, we propose a family of novel, practical techniques for broadcasting o...

In this paper, we consider a scenario where a source node wishes to broadcast two confidential messages to two receivers, while a wire-tapper also receives the transmitted signal. This model is motivated by wireless communications, where individual secure messages are broadcast over open media and can be received by any illegitimate receiver. The secrecy level is measured by the equivocation ra...

Mechanisms and protocol interactions for seamless handover of mobile multicast/broadcast services using unidirectional access networks in heterogeneous Mobile IP infrastructures are discussed and proposed. QoS based applications, such as content delivery, mobile TV, carousel and reliable downloads, requiring interaction channel, are considered, as well as recent standardization efforts for conv...
