Modern TVs have dimming features that can adjust backlight power in specific parts of the screen, sometimes even at the individual pixel level.

We wanted to see whether adapting BBC content could make use of these features and reduce energy consumption.

Introducing the energy saving concept of Lower Carbon Graphics

Developing and implementing a new idea which we believe has already saved energy in homes across the UK.

If "Music on TV" is such a big use case, maybe somebody should lobby TV manufacturers to include a low power "audio only" mode?

@joland @BBCRD
I have a Samsung smart TV that can play audio files (including lossless, in high def) from USB storage. The music player has a "Screen Off" option, and volume +/- on the remote still works when the screen is off.

It's more than 5 years old.

@joland @BBCRD
Unfortunately the "Screen Off" doesn't completely power off the display; on coming back to normal operation, the screen sometimes flickers, which can only be fixed with a power-off.

And when playing back FLAC files, it cuts off a bit (less than a second) from the beginning of each track.
