High latency and loss rates in the Internet make it difficult to stream audio and video without
introducing a large playback delay. To address these problems, we propose a prefix caching …

An important and unsolved problem today is that of automatic quantification of the quality of
video flows transmitted over packet networks. In particular, the ability to perform this task in …

While there is an increasing demand for streaming video applications on the Internet,
various network characteristics make the deployment of these applications more challenging …

This paper investigates the problem of assessing the quality of video transmitted over IP
networks. Our goal is to develop a methodology that is both reasonably accurate and simple …

Reliable transmission of compressed video in a packet lossy environment cannot be
achieved without error recovery mechanisms. We describe an effective method for …

Over the past few years there has been an increasing interest in real time video services
over packet networks. When considering quality, it is essential to quantify user perception of …

A method is proposed to protect MPEG video quality from packet loss for real-time
transmission over the Internet. Because MPEG uses inter-frame coding, relatively small …

In order to transmit an inter-frame coded Video signal, Such as an MPEG-coded Video
signal, over a packet-based net work Such as the Internet, the Video signal associated with …

Indiscriminated packet discards strongly degrade the quality perceived by end users of
MPEG video transmissions. This paper investigates different Quality of Service (QoS) …

We identify the importance of adaptation for the ubiquitous access to Internet multimedia
content. The variety of media types combined with the diversity of Internet connection …
