NEA Offers Live Webcast Friday



On Friday, November 20, the National Endowment for the Arts is hosting a forum about America’s artists and other cultural workers and the way that art works as part of this country’s real economy. Academics, foundation professionals, and service organization representatives will come together to discuss improving the collection and reporting of statistics about arts and cultural workers, and to develop future research agendas and approaches.

The NEA is inviting everyone to view this forum through a live webcast that will be available from 9 a.m. until 4:30 p.m. at www.arts.gov. In addition, an archive of the event will be available on www.arts.gov the week following the forum.

Web casting, or broadcasting over the internet, is a media file (audio-video mostly) distributed over the internet using streaming media technology. Streaming implies media played as a continuous stream and received real time by the browser (end user). Streaming technology enables a single content source to be distributed to many simultaneous viewers. Streaming video bandwidth is typically calculated in gigabytes of data transferred. It is important to estimate how many viewers you can reach, for example in a live webcast, given your bandwidth constraints or conversely, if you are expecting a certain audience size, what bandwidth resources you need to deploy.

To estimate how many viewers you can reach during a webcast, consider some parlance:
One viewer: 1 click of a video player button at one location logged on
One viewer hour: 1 viewer connected for 1 hour
100 viewer hours: 100 viewers connected for 1 hour…

Typically webcasts will be offered at different bit rates or quality levels corresponding to different user’s internet connection speeds. Bit rate implies the rate at which bits (basic data units) are transferred. It denotes how much data is transmitted in a given amount of time. (bps / Kbps / Mbps…). Quality improves as more bits are used for each second of the playback. Video of 3000 Kbps will look better than one of say 1000Kbps. This is just like quality of a image is represented in resolution, for video (or audio) it is measured by the bit rate.
