SYMM (SYnchronized MultiMedia) allows sound and images to work at the same time ("in synch".) You can synchronize by using either SMIL (Synchronized Multimedia Integration Language) or SYMM creation software.

Tim Kennedy is still our SMIL (rhymes with smile) Expert, and still in charge of JustSMIL. We just re-organized his great articles and gave them a bit of a new look.

Our SYMM area covers all of the other (non-SMIL) ways to synchronize and experience streaming multimedia. Proprietary products like QuickTime, RealPlayer G2, Windows Media Technologies and more are explored.

Check out both JustSMIL and SYMM and see which solution is best for you.
