You may assume that commercial video distributors will work with browser
vendors to implement or integrate CDMs for existing DRM back ends. Cox will
certainly do this. If multiple vendor browsers should employ a common CDM
integration interface, then this would certainly be used and preferred over
a scenario where a CDM must be integrated separately with every browser.
However, such a possible common CDM integration interface should be
maintained outside the scope of the current proposal.
