ABC is changing to HD
ABC main channel is making the transition to (HD) HIGH DEFINITION in December 2016. Viewers with HD compatible TVs (with MPEG-4 functionality) will be able to experience ABC in spectacular HD, including this year’s New Year’s Eve fireworks.
Viewers without an HD compatible television will still be able to continue to watch ABC in standard definition on channel 2 and 21.
To accommodate the HD upgrade there is a minor change which will impact ABC News 24. ABC News 24 will change from HD to SD (whilst remaining on channel number 24). So viewers who previously couldn’t receive ABC News 24 (because they didn’t have an HD TV set) , will be able to watch ABC News 24 following this change in December.
You may need to re-tune your TV sets to be able to receive ABC HD and ABC News 24.
