Digital Video Applications in the Curriculum
Questions and Answers from the April 6th Webcast


Q.

Where is your microphone?

A.

The microphone we are using resides on the desktop right in front of me. We are currently using a high quality microphone that is attached to our Polycom 512 video conferencing station. It is a very high quality mic that sounds great when used for applications such as this.

Q.

What is the time delay associated with a webcast?

A.

The time delay will vary depending upon the level of network congestion. The more congested and busy a network is, the longer the associated delay.

Q.

How much does it cost to be able to support and conduct webcasts?

A.

This is really a multipart answer.

First of all you need a RealMedia streaming server. These are sold in license packs that depend upon how many streams you want to simultaneously support. A license that supports 200 would cost somewhere in the neighborhood of $30,000.

You also need a fast machine that would be able to handle this type of application. Most likely you'd need a big Sun Solaris Unix box. That would cost between $40,000 - $60,000 depending upon which machine you select.

In addition, you'd need a few system administrators with Unix experience, hardware that would backup your Unix machine, and a fast 200 MB network connection / 600MB network card. So, in addition to close to $100,000 in one time expenditures, your recurring costs would vary. microphone we are using resides on the desktop right in front of me.
