Abstract

Video is rapidly becoming an important component of information delivered over the Internet. Thus there is a growing need for applications to deliver good quality video segments that is adapted to a variety of client devices operating under both wired and wireless platforms. Adaptation requires: (a) a framework to support physical and semantic adaptation of a video, and (b) a mechanism for describing video content, and the environment in which it is to be delivered. We address this need through DAVE - a system that uses a quality-driven approach to deliver adaptive video.

DAVE minimizes resource requirements by identifying relevant segments within a video and then scales the identified video segment to maximize user-viewing experience.

In this talk we present our quality-driven adaptation approach to deliver video to a variety of devices.
