This is a legacy article. For information on tuners and 4th Generation Tablo DVRs, go here.



Tuners decode the signal coming in from your OTA  (over-the-air) TV antenna and split it either two ways, for dual-tuner legacy Tablo DVRs, or four ways, for quad-tuner Tablo DVRs.




On legacy Tablo devices, a tuner is required for:

  • Watching a live TV program.
  • Recording a program.
  • Watching a live or recorded program away from home using Tablo Connect (unless your remote streaming quality is set to 'full').

Watching a completed recording does NOT require a tuner.

The more tuners your Tablo DVR has, the more concurrent live TV streams or recordings it can support. 

Tuner Reassigned?
Recordings take precedence over Live TV streams, so your live TV session may end if a tuner is needed for a recording. You can however un-schedule the recording in question and return to watching live TV if you prefer.


Other Things Tuners Are Used For

On legacy Tablo devices, tuners are also used to generate Fast-Forward Previews which are a pre-requisite for Automatic Commercial Skip processing. So if you enjoy those features on your legacy Tablo device, having extra tuners can come in handy.
