I can only assume this is a result of very extreme compression? Anyone else care to comment?
Just a theory but I had no way of verifying myself. Could this be adaptive streaming? What device are you seeing this with? Do you have another device to compare to?
The theory came from my trial with YouTube TV and the ability to see nerd stats. I had a Roku Ultra and ATV4K at the time and IIRC, the ATV4K was getting average bandwidth of 17Mbps while the Roku Ultra averaged over 40Mbps. Big difference?
I didn't correlate that to noisy dark backgrounds then but the theory came up again when I saw that on PSV with my ATV4K. I think it could be minimizing adaptive streaming to least possible bandwidth but can't measure or compare the two. I was leaving PSV at the time I noticed and can't recall if I compared to Roku Ultra then or not.
I did compare to DirecTV satellite as I returned to it and didn't see it there; I was pleased to see it gone. Not a fair comparison to streaming but to me it kind of supports the theory that adaptive streaming is to blame for what we saw; if same?
I'm not looking to start a debate, just offering a theory if someone could compare with actual data. It may be worth a look. I'd be interested to know since I'll likely be returning to streaming after my Directv discounts expire; just a one year offer to come back. If adaptive streaming is to blame, how can it be resolved? If it varies in manufacturers, is it app development or manufacturer OS?
No facts, just a theory. By PSV descriptions, on-demand is supposed to be better quality though I'm not sure I agreed. Some on-demand was better, to me, if it had less commercials and I could skip those too. Adding to DVR and checking on-demand when I had a choice was worthwhile on some channels.
