Authoring SMIL for the Helix DNA Client

Authoring SMIL for the Helix DNA Client

When your streaming presentation contains multiple clips, such as audio synchronized with sequential JPEG images, you use Synchronized Multimedia Integration Language (SMIL) to coordinate the parts. Pronounced "smile," SMIL is a simple but powerful markup language for specifying how and when clips play.

Recommended by the World Wide Web Consortium (W3C), SMIL is designed to be the standard markup language for timing and controlling streaming media clips. SMIL works for a media player similar to the way that HTML works for a Web browser. And just as HTML markup displays in any browser, the standardized SMIL language fosters interoperability between media players. You can find the official SMIL 2.0 specification at the W3C Web site.

W3C SMIL Resources - The W3C website has an extensive set of resources regarding SMIL.

Helix DNA Client 1.1.5 - This client supports SMIL 2.0, and can be used to tinker with SMIL support in the Helix platform.
