It's a surprise to many that you can get free over-the-air (OTA) TV with excellent HD image quality just by plugging an antenna into your TV. But even if you're OK with the reduced channel selection, the problem is that you're stuck with live TV. That means no time shifting or delayed viewing unless you pony up for one of the handful of OTA DVRs on the market.
Tablo is the latest entrant in the budding over-the-air DVR space, launching today on the crowdfunding site Indiegogo. It's a small black box that records over-the-air content and streams content to a variety of connected devices. You'll need to supply your own USB hard drive and antenna, plus you'll need a secondary device to watch content -- the box itself doesn't have a video output.
Tablo is promising support for Roku, Apple TV (via AirPlay), and Google Chromecast for TV watching, although when I talked with a company representative, Chromecast support seems more like a work in progress. Apps for both Android and iOS are on the way, and Tablo will be capable of streaming both within and outside your home network.
