Livecasting, Mobile Streaming

I just came across a couple of websites, such as justin.tv, livecast.com, mogulus.com and others with weired names. Once on the websites I desperately look for the "about" button potentially explaining what all these websites are about? I just haven t got it, but people happen to be fascinated of livecasting for quite a while:

1994 Steve Mann -
First person to transmitted his everyday life 24/7.

1996 Jennifer Ringley
JenniCAM
—subtitled "life, online"—was a popular website from April 1996 until the end of 2003.
Ringley's
innovation was simply to allow others to view her daily activities

1999 Lisa Batey
Started on HereAndNow.net streaming 24/7 in 1999, continuing into 2001.

1999 Josh Harris
"We Live In Public" [10] was a 24/7 Internet conceptual art experiment created in December 1999. With a format similar to TV‘s Big Brother.

2000 DotComGuy
Combined live streaming with social networking to assist the visually challenged.

2002 Joi Ito
First to do web publishing from a mobile device.

2004 Gordon Bell
MyLifeByts
, an experiment in digital storage of a person's lifetime, including full-text search, text/audio annotations and hyperlinks.

2004 Justin Kahn
Justin.tv, a platform for live video streaming online

2007 Justine Ezarik
Expansion
of justin.tv, Justine Ezarik took a different approach, often aiming the camera at herself

What do people do with all these wastes of giga-bytes?

I must confess: it's quite fascinating seeing qik.com working on my mobile phone streaming live...when...umh...I m doing exciting things... such as reading a newspaper:




But who will ever watch this? Not even myself. But it's fascinating indeed seeing working and perhaps that's already enough. Busines case is old thinking.

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.
