Multimedia the New Way

Netscape's <embed /> tag has come under fire for a number of reasons, both technical and political. Officially, it has already been made obsolete by a new tag called <object>, which has the blessing of Netscape, Microsoft, and the official World Wide Web Consortium (W3C) standards-setting committee. The <object> tag will do everything Netscape wants the <embed /> tag to do, plus a lot more.

Unfortunately, the 4 versions of Microsoft Internet Explorer and Netscape Navigator interpret the <object> tag somewhat unreliably, because they were released before the official standard for the tag was approved. The fact that most people are still using earlier browser versions has also slowed widespread use of the <object> tag. Alas, support of <object> in Microsoft Internet Explorer 5 isn't any better, nor does it look likely that the next update of Netscape Navigator will support the standard fully.

You can read more about the <object> tag, including an example of its current use, under "ActiveX Controls" in Hour 18.

Another beacon of hope has appeared on the Web multimedia horizon as well. The W3C has officially sanctioned SMIL 1, the Synchronized Multimedia Integration Language. When Web browsers start conforming to this new standard, you will have a reliable way to synchronize multiple sound, video, and animation sources on your Web pages. (Assuming, that is, that your intended audience has high-speed network connections capable of delivering multiple media streams by then.) You can dream of the possibilities as you read about SMIL at the http://www.w3.org Web site and experience an early implementation of SMIL in the Real Player G2 at http://www.real.com.
