Streaming real-time multimedia content over the Internet is gaining momentum in the communications, entertainment, music and interactive game industries as well as in the military. In general, streaming applications include IP telephony, multimedia broadcasts and various interactive applications such as multi-party conferences, collaborations and multiplayer games. Successfully realizing such a...

Multimedia conference is one of the important applications in the Internet. To support such an application over satellite networks, one has to address quality of service (QoS) and performance of IP applications over satellite. Research has been carried to study how satellite networks can support efficiently the IP based multimedia applications including voice, video and data and impacts of sate...

Network tomography using multicast probes enables inference of loss characteristics of internal network links from reports of end-to-end loss seen at multicast receivers. In this paper we develop estimators for internal loss rates when reports are not available on some probes or from some receivers. This problem is motivated by the use of unreliable transport control protocols, such as RTCP, to...

The Session Description Protocol (SDP) was intended to describe multimedia sessions for the purposes of session announcement, session invitation, and other forms of multimedia session initiation. SDP was not intended to provide capability indication or capability negotiation; however, over the years, SDP has seen widespread adoption and as a result it has been gradually extended to provide limi...

Status of this Memo This document is an Internet-Draft. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any t...

This document describes a profile called “RTP/AVP” for the use of the real-time transport protocol (RTP), version 2, and the associated control protocol, RTCP, within audio and video multiparticipant conferences with minimal control. It provides interpretations of generic fields within the RTP specification suitable for audio and video conferences. In particular, this document defines a set of ...

Flexible multimedia streaming such as advertisement insertion, location-based services, mobility, and wireless access are vital components that make existing Internet radio and TV networks more attractive to roaming users. All of these applications also provide added value to telematics and military usage, including coordination, education, situation awareness, distributed simulation, battlefie...

According to the discovery of available and suitable audiovisual services over IP, researches on the Quality of Service (QoS) for various multimedia application services are required. This paper presents evaluation of speech quality applying improved Packet Loss Concealment (PLC) algorithms with an end-to-end bidirectional transmission control scheme. We propose real-time transmission control s...

This work presents a framework architecture for the development of distributed real-time applications to be integrated into WWW clients. It assumes a WWW environment over networks providing a best-effort delivery service like the internets based on the IP protocol. The framework is that of an application programming interface (API) providing the program developer with the services needed by tol...
