While most televisions can display unencrypted cable signals, sometimes called Clear QAM (Quadrature Amplitude Modulation), the tuners in Tablo DVRs are not designed for this.
Tablo OTA (Over-the-Air) DVRs are instead designed specifically to receive digital signals from OTA TV antennas.
While 'clear cable' signals and content from cable cards are also digital, they are delivered in a totally different format than OTA TV signals so you won't be able to use Tablo as a replacement for your cable company's box or your cable card-capable DVR.
We are not currently considering adding support for cable cards or clear QAM.
