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.
Other Things Tuners Are Used For
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, having extra tuners can come in handy.
