That would be an incorrect assumption. Cox Communications has to satisfy
such obligations that definitely do exist, and this is true for most (all?)
US commercial video providers.

Cox requires that existing DRM/CP solutions be supported by this proposal,
and the defined CDM mechanism appears to satisfy this requirement. It is
not an option (at least at this time and for the foreseeable future) to
migrate these services to newly defined DRM/CP regimes. It may be possible
to do this over time, but it would first require the content industry to
migrate in that direction. Essentially it is the content industry who is
making the decisions about what CDMs will be necessary to commercially
employ their content.
