<Font Size = 1>
standard HTML 16 color palette can be referred to by name, and other colors will be
matched to the nearest color of a standard 232-color template. When creating billboards,
please test your billboard for effect on all types of monitors on which it is going to be
presented. S-Video output and Composite output from the V-Brick are supported.
Video Input
S-Video output from the VBrick to S-Video Input on the television yields the best picture to
the TV monitor. If you do have S-Video input into your television set, it is recommended you
use the S-Video output from the VBrick to the television. Most televisions also support
composite input. The overlay image as used in the billboard can sometimes have the effect of
"flicker" if the font is too small and used on a regular television. This is a product of the
output video signal and the television. On higher-grade monitors, the effect is significantly
reduced.
Font Sizes
It is recommended that font size 5 be used on the billboard. The VBrick has two types of
video output signals. If S-Video out is used, the picture is significantly better than the
Composite out. Text and graphics tend to appear sharper and do not flicker in S-Video as
much as they do in the composite out. If a flickering effect makes your font unreadable, make
it larger. Making the font bold or <STRONG> will reduce the effect of the flicker.

Transparent Background
A web page can be created with a transparent background. The video will show through and
any text or images will appear on top of the video. A custom META tag is used to support
this feature. In the <HEAD> portion of the HTML page, enter the following. The chosen
background color will then be overwritten by the transparent color.
