Good find but you don't explain how it relates to the OP and it does.
The FCC DSTAC had a choice between two Cable TV delivery schemes when using a downloadable security scheme and eliminating the cable card. Both would allow Consumer Electronics with a TEE and HTML5 <video> MSE EME to receive Cable TV without a cable box but one would be an APP written by the Cable Company and the other would require the cable companies to provide user guides, channel listings and any other access to servers to allow the CE company to write their own apps.
The FCC chose the latter over the objections of the cable companies and they have a 2 year period before the FCC mandate requiring them to support CE written apps.
In the OP Comcast has signed an agreement with Sony for it's Passage and Sony hired a REP to educate cable companies on various features that require DRM. Both these could apply to Vidipath where the Cable company DVRs support streaming to STBs and Smart TVs that support HTML5 <video> EME MSE and Playready or to a
App written by Comcast for those same platforms.
It ties to the OP on
Sony Passage being used by Cable TV operators (MSOs). See also Playready ND cite in the OP

Comcast just signed an agreement with Sony to use Passage. This plus last year's
Sony Job posting for a Sony representative to help cable companies with Vidipath, Miracast and more mean it's likely soon.
UHD Blu-ray or supporting the Digital bridge/Vidipath as a client is supported by EVERY CE company wanting to get in on the ground floor of ATSC 3 (UHD 4K antenna TV). But not for 4K media, for 1080P and lower as
Antenna TV will be free, has DRM and will have a wider market than Cable. It will soon be supported on EVERY new Cell phone likely by Mandate of the FCC in the US because it will be used for the emergency alert. Cell phones use almost the same frequencies that TV uses, will use the same modulation scheme, use the same software stack for the UI and the same for video (HTML5 <video> mse eme). What is missing is HEVC which top end Cell phones now support.
UHD Blu-ray is the precursor for ATSC 3 because it uses the same software stack. There are FCC leaked proposals using UHD Blu-ray players as the STBs to accelerate the adoption of ATSC 3 OR UHD client STBs for the UHD blu-ray digital bridge. We will know this is coming when combo ATSC 1 & 3 Network tuner/DLNA servers are being advertised for sale which should occur late 2016 at the earliest and mid to late 2017 at the latest. Microsoft announced a Antenna TV DVR coming for the XB1 that supports 1080P. 1080P is not available for ATSC 1, it's only available for ATSC 2 and 3 and ATSC 2 looks like it's going to be skipped.
Microsoft and Sony knew this and have plans to support 4k Antenna TV and is why both are supporting Phones. There will be a synergy between the living room Game Console and Cell Phones beyond the Second screen which is also part of ATSC 3. Vidipath and the UHD Blu-ray digital bridge are part of this. Sony mentions Playready ND in the UHD Blu-ray digital bridge proposals and Microsoft mentions using it for DVR and Live streaming. Vidipath is now associated with Cable TV DVRs but the same scheme will work for Antenna TV.
Why are Cable companies pushing IPTV with their own apps? The Antenna TV model is most likely going to be a combo of TV served as IPTV from a Vidipath antenna TV tuner on the home network and a Cable modem serving IPTV on the same network. The consumer has a choice of free TV via antenna with some for pay premium channels and IPTV from Cable modems, some free and some for pay. A local antenna TV scheme with multiple stations can support about 100 separate TV streams but Cable can support hundreds and hundreds more allowing more choice.
