How about streaming actual 4k content at not a terrible bitrate

Youtube 4k is 25mbps and I don't think anyone's 4k is over 100mpbs.

  For streaming, probably true. However my 2016-era 4K camera records at up to 150Mbps and I noticed recently that due to compression I was totally unable to show off some gorgeous telephoto video of a hummingbird bathing in a river because the fast running water looked truly horrible under compression, even though the original video looked great. I would love 100mpbs streaming options.

    Bitrate on a camera and on a video aren't comparable. The camera has to use a compression algorithm that can run real time on very low power (the cpu in a camera is probably ~5-10 watts. Anything non-real-time video will have been re-compressed and can probably maintain quality at roughly half the bitrate.

      well if I could get sufficient bitrate to display my cute hummingbird video I would be very happy

Blu-ray 4K content is an absolute maximum of ~150Mbps, but can be below 100Mbps. So with a 1G/1000M connection you can stream have 7-10 streams of 4K Bluray quality video simultaneously. * https://en.wikipedia.org/wiki/Ultra_HD_Blu-ray https://en.wikipedia.org/wiki/Ultra_HD_Blu-ray What does going to 10G, let alone 25G, get you? Are you really planning on 70-100 4K simultaneous movie streams on 10G, or 160-250 simultaneous streams on 25?

  That's missing some of the bigger picture. One of the reasons streaming 4k content is at a lower bitrate is because it has to deal with network hiccups and fit inside the buffer of most playback devices. A computer or phone has plenty of room, but streaming 4K content to a TV or chromecast/roku/firestick/etc. does not. Faster bandwidth means keeping the bucket full more reliably.

    Are we sure that is true? Why would Netflix or similar pay out to give a better picture? Outside of a few AV aficionados, I doubt the average consumer would know or care.
