PRIMARY CONSIDERATIONS
Four primary components must be considered in broadcast design for the Web: The audience, screen size, color usage, and mouseless navigation.
You will soon realize that this entails a fight for territory inside the tv screen.

Considerations will be such as what percentage of the screen is is to be devoted to the actual video?
What is more important, the video image or the web page?
What colours can I use?
What are limitations due to the technology? How can I resolve the problem of bright eye-catching colours?
What is the smallest font size I can get away with?
How can I put as much information on the page?
Will the viewer be able to read it, let alone does the viewer want to read it l?
Will my navigation buttons or hot links be easily accessed by the simple WebTV controller?
Should the TV image be shown full size with ovelay assets or as a "Picture-in-Picture"?

The following sections of the manual will hopefully help to resolve these challanges.
