The billboard text generated by the browser is Times Roman. The Font sizes supported are <Font Size = 1> to <Font size = 7>. Background color and images are also supported. The 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.

•The drawing area for Billboard is about 600X400 pixels.

•With a font size of 7, 8 lines of text fit on the screen.

•With a font size of 6, 13 lines of text lines fit on the screen.

•With a font size of 5, 18 lines of text fit on the screen.

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.

<META HTTP-EQUIV="TRANSPARENT" CONTENT="YES">
