Tuners decode the signal coming in from your Over-the-Air TV antenna and split it either TWO ways for dual-tuner Tablo DVRs or FOUR ways for quad-tuner Tablo DVRs.
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.
So the more tuners your Tablo DVR has, the more concurrent live TV streams or recordings it can support.
