Test options in the System Attributes Inspector
The System Attributes Inspector contains the following options that you can select as the tests for a case:
Tests the actual bandwidth (not modem speed) that is available to the viewer's system. From the Bitrate
Bitrate
menu, choose a predefined bandwidth (expressed in bits per second), or choose Custom and then enter an integer
value greater than zero in the Bitrate box. This test evaluates as true if the viewer's system bitrate is equal to or greater
than the value you specify. Otherwise, the test evaluates as false.
Tests for the language that the viewer's system is using. From the Language menu, choose a predefined
Language
language, or choose Custom and then enter a language prefix (such as "ja" for Japanese) in the Language box. This
test evaluates as true if the language you choose exactly matches the language that is specified by the viewer's prefer­
ences. Otherwise, the test evaluates as false.
Tests whether the viewer's system supports an extension. Enter the name of the extension in the Required
Required
box. This test evaluates as true if the viewer's system supports the extension. Otherwise, the test evaluates as false.
Width and Height Tests for the viewer's monitor dimensions. In the Width and Height boxes, enter the width and
height (in pixels) of the viewer's monitor. Enter integer values greater than zero. This test evaluates as true if the player
application can display presentations at the dimensions you specify. Otherwise, the test evaluates as false.
Depth Tests for the viewer's monitor color depth. From the Depth menu, choose the predefined depth of the screen
color palette that is required to display the items in the case. You can also choose Custom from the Depth menu and
then enter a depth (in bits) in the Depth box. Enter an integer value greater than zero (such as 8). This test evaluates
as true if the player application can display a video or image that has the color depth you specify. Otherwise, the test
evaluates as false.
Use Captions Tests whether the viewer's player application is set to display captions. Select this option if your case
includes a text version of an audio item—for example, for viewers who have a hearing disability. This test evaluates
as true if the viewer's player application is set to display captions. Otherwise, the test evaluates as false.
Overdub Tests whether the viewer's player application is set to play audio overdubbing or text captioning. Choose
an option from the Overdub menu. This test evaluates as true if the viewer's preference is the same as the option you
chose from the Overdub menu. Otherwise, the test evaluates as false.

Working with regions in SMIL presentations

About regions
A region is a defined area of the presentation that controls the size, position, and scaling of a media item. You can
also create subregions to place a region in a larger region. Subregions move with their larger region. One advantage
of using GoLive to create SMIL presentations is that you don't have to explicitly define and assign regions. When you
add an item, GoLive automatically defines a region for the item and assigns it to the item for you. When you resize
or reposition an item, GoLive also changes the region's properties in the source code for you.
You can also manually create new regions and assign items to the regions. For example, you can assign the same
region to display different video items at different times in the same location. Or, you might want to prototype
different layouts of items and quickly compare various positions and sizes for the items. After manually creating
several alternate regions for the items, you can then reassign the items to the alternate regions and instantly see the
different layouts.
