Size of 4K broadcasts?

Post by pixelstuff »

How big are 4K recordings likely to be on the new ATSC 3.0 system?

Full HD interlaced broadcasts in my area seems to run from 3.5 GB to 7 GB per hour depending on the channel.

We have seen 4K HEVC content in testing range from 13 to 20Mbps. Figure roughly 7GB per hour.

So that is similar filesizes to ATSC1.0. I guess that isn't surprising as ATSC 3.0 will be HEVC which is two generations ahead in terms of encoding methodology.
