Well, I've seen Comcast's transition from QAM to IP video coming for awhile but even I'm surprised to read this rumor today over at Light Reading (a well-respected industry news source). Comcast May Go All IP by End of Year – Rumor | Light Reading Note that the rumor isn't purporting that Comcast will turn off QAM service this year, only that it will officially deprecate it by making all new subs IP-only. I'm pretty sure all X1 boxes already deployed can seamlessly switch over to IP and let their QAM tuners lie dormant. Given that X1 already accounted for about half of all deployed STBs at the end of 2016, I would imagine Comcast would switch those subs over from QAM to IP somewhere around the same time (year-end '17). Given that there's not going to be a successor to CableCARD, I imagine it will be up to TiVo to try to work out an arrangement to make their boxes continue to work with Comcast TV service at some point in the next few years when they inevitably cease QAM broadcasts all together in order to free up all that bandwidth.
