The 4th generation Tablo has either two or four over-the-air TV tuners, depending on which model you've chosen.

The primary function of these tuners is to decode the signal coming in from your over-the-air TV antenna, but they also perform other functions. 

The 4th generation Tablo also has either two or four 'virtual' tuners used to stream and record free streaming channels.

An over-the-air tuner is required for:

  • Watching a live Over-the-Air antenna TV program
  • Recording an Over-the-Air antenna TV program

An over-the-air tuner is NOT required for:

  • Watching a completed Over-the-Air antenna TV recording

Over-the-air tuners are also used for:

  • Generating fast-forward previews on ALL completed recordings
  • Archiving antenna TV recordings when using onboard storage

A virtual tuner is required for:

  • Watching a live free streaming TV program
  • Recording a free streaming TV program

A virtual tuner is NOT required for:

  • Watching a completed free streaming TV recording

 

This means that the 2-tuner 4th generation Tablo can support up to two concurrent antenna TV streams or recordings AS WELL AS up to two concurrent free TV streams or recordings. 

The 4-tuner 4th generation Tablo can support up to four concurrent antenna TV streams or recordings AS WELL AS up to four concurrent free TV streams or recordings. 

For example, at the same time across all of the smart TVs, streaming, and mobile devices in your home, with a 2-tuner Tablo you can:

  • Watch a live over-the-air antenna TV program in the living room
  • Record a live over-the-air antenna TV program on another channel
  • Watch a free streaming program in the family room
  • Record a free streaming channel

OR

  • Watch a live over-the-air antenna TV program in the living room
  • Watch a live over-the-air antenna TV program in the family room
  • Watch a completed over-the-air antenna TV recording in the bedroom
  • Record a free streaming program
  • Watch a free streaming program in the kitchen 

 

Seeing a Tuner Reassigned Error Message?

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.
