Embedding Video in the Homepage
When embedding video in the homepage, in addition to indicating the URL, some scripts should
be added to download plug-ins used to view video images. The following example simply displays
title text and a real-time video window in Internet Explorer or Netscape. The user name and
password should be configured in advance. Those who are familiar with HTML can easily add
more components or rewrite the code to create a more vivid and useful homepage.
