I don’t have a jellyfin server but 1MB/s (8mbps) for each person watching 1080p (3.6Gb per hour of content for each file) seems reasonable. ~3MB/s (24mbps) upload and as much download should work.
Why don’t people use Mb/s and MB/s which makes it so much clearer what you’re talking about
The best format imo is MB/s and Mbit/s
It avoids all confusion.
Back in the day, the rule was mbit (megabit) for data in transfer (network speed) and MB (megabyte) for data at rest, like on HDDs
So mbit/s instead of Mbit/s ? But the M in Mega is always capitalized though, except the k in kilo.
but why?
@Moneo @SigHunter Networking came to be when there were lots of different implementations of a ‘byte’. The PDP-10 was prevalent at the time the internet was being developed for example, which supported variable byte lengths of up to 36-bits per byte.
Network protocols had to support every device regardless of its byte size, so protocol specifications settled on bits as the lowest common unit size, while referring to 8-bit fields as ‘octets’ before 8-bit became the de facto standard byte length.
Bigger number sounds better for the ISP.
The real answer?
Data is transmitted in packets. Each packet has a packet header, and a packet payload. The total data transmitted is the header + payload.
If you’re transmitting smaller packet sizes, it means your header is a larger percentage of the total packet size.
Measuring in megabits is the ISP telling you “look, your connection is good for X amount of data. How you choose to use that data is up to you. If you want more of it going to your packet headers instead of your payload, fine.” A bit is a bit is a bit to your ISP.
1mbps is awfully low for 1080. Or did you mean megabyte rather than megabit?
I had a hunch that writing the actual Upload/download speed tather than mbps was probably wrong. My bad, my internet provider lingo is rusted.
Gotcha. Typically lowercase b=bit and uppercase B=Byte, but it’s hard to tell what people mean sometimes, especially in casual posts.
Come to think of it, I messed up the capitalization too. Should be a capital M for mega.
Just look at the bit rate of what you are streaming and multiply it by 3 then add a little extra for overhead.
Are you transcoding?
4mbit per client for 1080 is generally a workable minimum for the average casual watcher if you have H265 compatible clients (and a decent encoder, like a modern intel CPU for example), 6 - 8mbit per client if its H264 only.
Remember that the bitrate to quality curve for live transcoding isn’t as good as a slow, non-real-time encode done the brute force way on a CPU. so if you have a few videos that look great at 4mbit, dont assume your own transcodes will look quite that nice, you’re using a GPU to get it done as quickly as possible, with acceptable quality, not as slowly and carefully as possible for the best compression.
My family is very satisfied with 6 mbit/s per stream. Some HEVC, most H264. They see it as high quality. 3 Streams would be 18 to 20 Mbit/s
How expensive is internet? If its cheap go overkill and don’t worry about it.
I have 35mbps upload from the ISP, and limit each stream to 8mbps. This covers direct streaming all my 1080p content and a 4K transcode as needed.
