How does Streaming Media work?
There is a lot of protocol that goes into the process of streaming media. In order to understand this process you need to understand basic terms:
IP: Internet Protocol: underlying protocol which transmits data across the internet; supports real-time transfer of data
HTTP: Hypertext Transfer Protocol: Protocol for transfering hypertext files or web pages
RTP: Real-time Transfer Protocol: allows the actual transfer of data in real time (allows one-way stream: server --> client)
RTSP: Real-time Streaming Protocol: allows two -way protocol and allows client to have more control over streaming media (i.e.- stop, start, pause like with a remote control for DVD's) as well as request info about the data in a format-specific way, specific transport type and destination, and the like
Unicast: "one to one" each end user gets seperate stream (one cast)
Multicast: "multiples" allows multiple streams to be sent to multiple end users
These are some terms just to get you started. Understanding how the technology of streaming media works can seem difficult, but if you break it down into simple steps, its not so bad. More on this later. Good luck!

Flash as a Form of Popular Entertainment
Flash is a great way to view animation imbedded directly into the web page. Thousands of people a week go to homestarrunner.com for free (if bizarre) entertainment. Started by brothers Mike and Matt Chapman in early 2000, this Flash cartoon has grown steadily in popularity since its inception. Although the cartoon itself is free, the brothers have made their living off the site from merchandise sales. This is a great example of innovation and creativity blending with emerging technology.

Streaming video is incredibly useful in today's world. For example, in our apartment, we do not have a TV, but when we need to catch the new episode of the Office that we missed we hop online to http://www.nbc.com/ and watch it there!
4. iBiquity
-Is a company formed by the merger of USA Digital Radio and Lucent Digital Radio, with the goal of creating an in-band on-channel (IBOC) digital radio system for the United States.
-It can operate on both AM band and FM band broadcasts either in a digital-only mode, or in a "hybrid" digital+analog mode. Most broadcasts for the foreseeable future will use the hybrid method, reportedly giving AM stations "FM quality" sound, while allowing FM stations to achieve "CD quality" audio or carry multiple audio programs.
-The technology is marketed under the term HD Radio. Note the "HD" in HD-Radio stands for "Hybrid Digital" not "High Definition" in more popular usage.

2. Flash
-Adobe Flash, or simply Flash, refers to both a multimedia authoring program and the Adobe Flash Player, written and distributed by Adobe.
-Uses vector and raster graphics, a native scripting language called ActionScript and bidirectional streaming of video and audio.
-The Flash Player was originally designed to display 2-dimensional vector animation, but has since become suitable for creating rich Internet applications and streaming video and audio.
-It uses vector graphics to minimize file size and create files that save bandwidth and loading time.
-Flash is a common format for games, animations, and GUIs embedded into web pages.

1. Media Server
-Definition: a computing device, ranging from an enterprise class machine providing video on demand, to, more commonly, a small home computer storing various digital media.
-Simply stores and shares media
-In a home setting, a media server acts as an aggregator of information: video, audio, photos, books, etc.
-The only requirement for a media server is a method of storing media and a network connection with enough speed to allow access to that media.
