You need a mechanism for putting control.html to player.html back together. There are several approaches:Server-side script : Recompose the page server-side - eg. PHP or SeverSide Includes (SSI).
AJAX : Serve a page containing one component with JavaScript/ AJAX to fetch the other component and insert it dynamically into the DOM.
Inline frame : Serve a page containing one component with an inline frame containing the other component.
(1) is by far the easiest and the one I recommend if available to you.
(2) Not too difficult if you already know AJAX/DOM scripting. Otherwise it will take a little time to master a couple of things.
(3) A bit messy as the controls need to communicate into (or out of) an inline frame. I've done this sort of stuff in the past and it's not so bad once you've got your mind round what is effectively window-window addressing. However, I suggest this is the least attractive of the options.
Hope this helps.
