TiVo today is introducing a new set-top box, the TiVo BOLT OTA, which will join its existing lineup of TiVo BOLT-branded devices, including the voice-controlled BOLT VOX DVRs, launched last year. This new device, as its name suggests, is designed for cord cutters who use a digital antenna to watch live TV over-the-air. It will replace the TiVO Roamio OTA DVR, which will no longer be sold.

Specifically, the BOLT OTA 4K Ultra High Definition capable set-top box is designed to work with almost any HD antenna and TV set, as a way for customers to ditch expensive cable or satellite TV without losing the ability to watch and record live TV.
