You've got the purpose of CableLabs confused.  When
they're not accepting kickbacks, charging a fortune
for product certification, and constantly changing
their specifications without incrementing version
numbers, they are supposed to be the unified voice of
the cable operators.  They have nothing to do with the
content producers.

IPTV is not subject to CableLabs approval, at least
not in it's current incarnation.  In fact, nothing is
really subject to CableLabs approval (see the number
of uncertified DOCSIS 1.0 cable modems about five
years ago), but if you don't get your products
CableLabs certified, then you likely won't be allowed
to bid on contracts put forth by the cable operators.

(Yes, I dislike CableLabs, and I don't hide it.  In my
view, they really are an incompetent and corrupt
organization.)

That said, open source hardware or software will never
get CableLabs approval.  CableLabs reserves the right
to revoke encryption keys on devices if they are
compromised (and I'm surprised they didn't revoke
Motorola's keys when a bunch of their modems were
cracked - but, Motorola is one of the key players in
CableLabs).

CableLabs is now much more open than it used to be -
previously the submission documents required
membership to view, but they are now freely available
on the CableLabs website.  These documents show some
of the requirements for security that CableCARD will
have to meet:

http://www.opencable.com/downloads/CHILA.pdf

>From the second document:
As to each of the Host Devices made under this
Agreement, Licensee covenants to CableLabs as follows:
(i) The Host Device, at the time manufactured,
contains no integrated circuit, ROM, RAM, software or
other device or functionality that:
  (1) enables copying or recording of Controlled
Content, other
than as permitted by the Compliance Rules or
  (2) interferes with or disables the ability of a
Cable Operator to communicate with or disable a
CableCARD or services being transmitted through a
CableCARD.
(ii) At the time of manufacture, it will maintain
control of content copies consistent with copy control
instructions or the encryption mode indicator bits
transmitted with digital signals as specified in the
OpenCable Specifications.
(iii) At the time of manufacture, it is designed to
effectively frustrate tampering and reverse
engineering directed towards defeating copy protection
requirements in accordance with the Robustness Rules.
(iv) At the time of manufacture, it will not transmit
or decode
Controlled Content received from the cable television
transmission without proper authorization from the
Cable Operator.
(v) As used in this section 9.2(c), “at the time of
manufacture” shall mean at the time of manufacture
of the Host Device and shall also include, but is not
limited to, any subsequent modifications, upgrades,
downloads, modules, plug-ins, or attachments to such
Host Device made by or at the direction of Licensee or
its Affiliates, or otherwise specifically promoted,
marketed, distributed by or at the direction of
Licensee or its Affiliates.
(vi) Licensee shall not service any licensed product
that it determines to have been modified after
manufacture to be non-Compliant.
<< End of CableLabs document>>

So, in short, Open Source will get the big red
"DENIED" stamp on CableCARD.  Our only hope is reverse
engineering outside of North America where the patents
and DMCA don't apply.
