SMIL and script

SMIL and script

is there a way perhaps using ecmascript to move, for instance an  
animation** to its start position?

Whilst a user might have buttons to play pause and rewind, but where  
one or more individuals and or services which may be  remote, is a  
means provide for them to engage?

what is sought  is  a way to emulate one and only one of the  buttons  
through script.
