But some browser do not support the <EMBED>. FOr example in Internet EXplorer we used the <IMG DYNSRC= > tag. In order for the <IMG DYNSRC> part to be not executed in Netscape, we can used the <NOEMBED> and </NOEMBED>. So what ever is enclose within this two tags will not be executed.
<EMBED SRC="monkey.mpeg" WIDTH=160 HEIGHT=220 ALIGN="left" AUTOPLAY="true" LOOP=INFINITE ONCURSOR="play"> <NOEMBED> <A HREF="monkey.mpeg"> <IMG DYNSRC="monkey.mpeg" LOOP=INFINITE WIDTH=160 HEIGHT=220 ALIGN="left" BORDER=0> </A> </NOEMBED>
In HTML 4.0 there is another tag known as <OBJECT>. An example of used is as follows:- <OBJECT title="Monkeys in the wild">> <OBJECT data="monkey.mpeg" type="application/mpeg"> <OBJECT src="monkey.jpg"> A very thirsty Chimp </OBJECT> </OBJECT> </OBJECT>
The <OBJECT> acts as a fallback policy. Should the MPEG fails to run, it will try to display the JPEG file and when that fails it will simply display the text. Unfortinately Internet Explorer 4.0 has some problem with the <OBJECT>.
