Streaming Audio and Video over the Internet: Challenges and Pitfalls
Amy Csizmar Dalal

Tuesday, September 28, 2003 at 3:30pm in Olin 320

According to recent commercials from cable and cell phone providers, we
should all be able to watch DVD-quality, full-motion video and receive
stereo-quality audio over the Internet. If you’ve ever tried to watch a
video clip from CNN’s or ESPN’s web sites, or listen to an Internet radio
station, you know that the commercials couldn’t be further from the truth.
Sending good quality, or even barely acceptable quality, video and audio
over the Internet is a difficult challenge. Figuring out what exactly
constitutes “good” or “acceptable” quality audio and video, and how we
measure “good” and “acceptable”, is an equally difficult challenge.
In this talk, I’ll discuss why both of these are difficult problems.
I’ll also discuss a novel approach to the measurement problem, which can
be used to predict what a user would say about the quality of a video
or audio stream, without asking the user directly.

Refreshments will be served.

Amy Csizmar Dalal is an Assistant Professor
of Computer Science at Carleton College.
