Actually Eric, 

They are not.  I posted about this (no one seemed to have notice) a couple
of months back -- see here:

And from the FCC ruling FCC 10-181:

44. Contrary to Comcast, Verizon and NCTA’s assertions, we believe that it is important to
define a baseline of functionality to ensure that consumers who network their devices and device
manufacturers can rely on networked devices’ ability to communicate with leased set-top boxes.
However, as with the physical interface itself, 

we find that it is appropriate, at this time, to refrain from
specifying the exact manner in which this baseline of functionality is to be implemented. Accordingly,
we modify our rules to require that the IP-based connection deliver the video in a recordable format (e.g.,
MPEG-2, MPEG-4, h.264), and pass through closed captioning data in a standard format.

We also believe more advanced functionalities are necessary to provide a foundation for a retail market of
navigation devices that are connected to leased set-top boxes with limited capabilities.149 Those
functionalities include service discovery, video transport, and remote control command pass-through
standards for home networking. While these functionalities may exist in some form today,150 there is
considerable work ongoing in industry standard bodies to provide those functionalities in a manner
designed for IP-based and home network solutions. We, therefore, do not mandate that these additional
functionalities be supported by cable operators immediately. We do, however, wish to ensure that
consumers benefit from these additional functionalities in a timely manner, and require operators to
provide these additional functionalities by December 1, 2012, but do not mandate a particular means by
which these functionalities are to be provided.
