What's interesting to me is that Charter seems to be implying that the only thing ending anytime soon is support for CableCARD --i.e. that they do NOT plan to get rid of QAM cable TV more broadly, and switch over to IPTV-only, as their Alaskan "cousin" GCI recently did in order to also make high-split upgrades to their data network. Charter says that the reason their high-split upgrades will eliminate CableCARD support is because it will eliminate the specific upper frequency that CableCARDs use for OOB (out-of-band) upstream communication. But they also raise the possibility that they may be able to simply shift that OOB frequency even higher after the high-split upgrade. In other words, Charter is saying "We may be able to bring support for CableCARD back in the relatively near future after initially dumping it."
While HDHomeRun CableCARD devices can apparently be software updated in order to use a hypothetical new higher OOB frequency in the future, it's unclear if that's possible for some, or any, TiVo DVRs. Frankly, I can't see why Charter would even bother to try and re-instate CableCARD support, given how few customers even use it. Based on the FCC's last public release of the numbers of CableCARDs in use a year or two ago, I calculated that they represented only about 0.5% of all eligible cable TV subscribers in the nation.
Perhaps Charter is simply raising that possibility to soften the blow in terms of the media coverage that they're getting now over yanking support for TiVo? As I say, it don't really see how it's in their economic interest to keep CableCARD alive, especially if it's not possible for TiVo DVRs, only other less-popular CableCARD devices such as HDHomeRun tuners.
And as I say, I have to wonder how much longer Charter will even support QAM TV more broadly. My guess has been that once they start getting big shipments of those new 4K HDR streaming devices in stock, from their new joint venture with Comcast -- which isn't expected until next year -- they'll go market-by-market handing and mailing those out to customers in order to get all their Spectrum cable TV subs switched over to accessing it via their IPTV app and then shut up QAM TV completely. Guess we'll see what unfolds in Charter-land next year...
