Humax has a device called Aura in the UK which combines Freeview (live TV) DVR with Android TV, which is interesting.
Humax
Yeah, that's the same product I had linked to in post #8 above. As I said, if Humax could do an OTA DVR running on Android TV for the UK, I don't see why TiVo couldn't do one (using their own UI in the DVR app) for the US market.
But there's been so much tumult at TiVo over the past few years (mergers, spin-offs, etc.), with reports saying that they've considered completely dumping the retail market at times, that it's very questionable whether the company has the appetite for cooking up a new retail DVR for the sliver of US households that use an OTA antenna. Nielsen says only about 13% of US households use an antenna and my guess is that hardly any of those are interested in spending money on an OTA DVR. Meanwhile, TiVo is far more focused on providing solutions for pay TV operators.
My read of OTA households is that they don't want to spend a ton of money on TV and/or they're just not all that interested in TV. And to the extent that they DO spend money on TV, it's for streaming services like Netflix, Hulu, etc. (Hulu, in particular, largely replaces the functions of an OTA DVR with its next-day access to current primetime shows from ABC, Fox and NBC. Throw in the free apps from CW and PBS and all that's really missing is CBS, which you can get from Paramount+.)
For OTA folks who are motivated to search out a first-class DVR experience running on Android TV, well, they can buy an Nvidia Shield and install the Channels DVR server software to run on it and record to the Shield's internal or attached storage. Also need an HDHomeRun tuner connected to the same router/network as the Shield. Given how mature and full-featured the Channels DVR UI/UX seems to be now, it's questionable how many potential buyers would opt for a competing TiVo solution versus that. For those who want a simpler headless OTA DVR solution that they can access via apps on pretty much any streaming device, there's Tablo.
So, yeah, I don't see any reason why TiVo
couldn't bring something like that Humax Freeview DVR to market here in the US but I think there are plenty of reasons why they won't choose to. The market for OTA DVRs is a niche where TiVo has been losing ground to smaller, more nimble competitors for the past few years.
