software components that work together to create, store
and deliver media files over the web.
Each streaming technology has three components that
affect you and the students who use your web site.
1. Servers and media files
2. Media players or plug-ins (students)
3. And, encoding and creation tools
Servers and media files:

How to Put QuickTime
Movies into Web Pages?
You will need to follow the

The basic command for placing any QuickTime movie
into a web page is EMBED.
This is what a basic QuickTime HTML statement
<EMBED SRC="Sample.mov" HEIGHT=120
Replace the name "Sample.mov" with the name of the
movie you wish to place on your page.
Also, change the values for height and width to match
the dimensions of your movie. If you aren't
sure about the dimensions of your movie, open your
movie in the QuickTime movie player and
select Get Info from the Movie menu. Then select
Choose Size from the pop-up menu.
The QuickTime EMBED command has more attributes than just
Height and Width. Some of
the more basic attributes are explained in detail below.
HEIGHT = Size in pixels
This attribute specifies the height (in pixels) of the embedded
document. The Height parameter is required
for any standard QuickTime embedding. If you would like to have
the QuickTime controller on your
movie, then add 24 to this attribute. For example.
The actual dimensions of a movie could be...Height = 120, Width =
160. For a controller to be
present on the web page, 24 would be added to Height=120 resulting
in Height=144. The HTML
text will look like this :
<EMBED SRC="Sample.mov" HEIGHT=144 WIDTH=160>
WIDTH = Size in pixels
This attribute specifies the width (in pixels) of the embedded document.
The Width parameter is required
for any standard QuickTime embedding. This attribute is unaffected by
the presence of a controller.
CONTROLLER = Value
Controller is an optional parameter. This sets the visibility of the movie
controller. Acceptable values
for this parameter are True and False. If you do not specify, the default
value is True.
