Digital over-the-air TV works similarly to analog over-the-air, but it's slower to change channels because the TV has to wait for a frame that isn't a delta from a previous frame to display a coherent image. That's just sort of par for the course with modern digital compression, you could increase the number of such frames but then the compression gets less effective and you'd still have more of a delay than with analog.

- aksss 5y agoDigital over the air was better quality than cable in my area for quite a while. I don’t use either now but I think cable was 720 and OTA was 1080.
