Tuner Requirements for Highest Quality Setting (1080 - 10Mbps, 720@60fps) – 4-Tuner Tablo DVRs

When Tablo launched, it supported a frame rate of 30 frames per second (fps) on all recording qualities. The HD1080 – 10Mbps, 720@60fps recording quality was added via the 2.2.6 firmware update.

With this recording quality selected, Tablo will record broadcasts in 720p at 60fps in its native broadcast quality. The majority of broadcasts in this quality are sports broadcasts.

How It Works

Since this process requires Tablo to encode twice as many frames in its video – 60fps vs. 30fps - the HD1080 – 10Mbps, 720@60fps recording quality requires considerably more processing power and bandwidth from the Tablo DVR’s internal hardware. 

In some instances, this setting could negatively affect the quality of the video if four simultaneous 60fps live streams were in progress.

In order to preserve image quality across streams, Tablo’s fourth tuner will be temporarily disabled if any 720p stations are being recorded at 60fps. This is true ONLY for 4-tuner Tablo DVRs using the HD1080 – 10Mbps, 720@60fps recording quality. 

If a tuner cannot be reserved, (i.e, if four recordings are occurring at once), Tablo will automatically record the last scheduled airing at 30fps instead of 60fps.                           

This failsafe is only put into action on the 4th active recording, which is why this is NOT seen on 2-tuner Tablo DVRs.

To avoid locking the 4th tuner and still use the 1080 quality, simply change your Tablo DVR's recording quality to 1080 @ 8Mbps. Note: this will remove the 60fps capture on 720p channels.

We are working with our technology partners to remove this restriction in the future.
