Multimedia networking, especially the delivery of video over the Internet, accounts for a large fraction of today's and future computer networks. Working with actual video provides several challenges on different technical and social levels. Video traces - a representation of video data and video quality in textual format - present a different approach to facilitate studies with video traffic. This book provides a comprehensive introduction to video traces and their use in networking research. After first providing the basics of digital video and video coding, the book introduces video traces, covering the metrics captured in the traces, the trace generation, as well as the statistical characteristics of the video characterized in the traces. The book then examines the use of the video traces in networking research. It details the practical aspects of transporting video over Internet Protocol (IP) networks and the simulation of video transport using traces, including the simulations that incorporate the impact of transmission errors using offset distortion traces. In addition, coverage presents software tools and utilities that facilitate the use of video trace.
