Quicktime
Enables your computer to handle media in many different file formats.

Streaming involves sending a file (movie or audio) from a server to a client over a network such as the Internet. The server breaks the
data into packets that can be sent over the network. At the receiving end, the packets are reassembled by the client and
the file is played as it comes in. A series of related packets is called a stream.Streaming is different from simple file transfer, in that the client plays the movie or audio file as it comes in over the network, rather
than waiting for the entire movie to download before it can be played. In fact, a streaming client may never actually
download a streaming movie; it may simply play the movie's packets as they come in, then discard them.Movies can be streamed using a variety of protocols, including:
HTTP (Hyper Text Transport Protocol)- considered progressive download- not true streamingRealMedia
FTP (File Transfer Protocol)
HTTP and FTP are file transfer protocols.RTP (Realtime Transport Protocol).
RTP is used for real time streaming. The movie packets are sent in real time, so that a one-minute movie is sent overthe network in one minute. The packets are time-stamped, so they can be displayed in time-synchronized order. Because packets are sent in real time, RTP streaming works with live content in addition to previously-recorded movies. It can even carry a mixture of the two.
