Re: Why does no Roku streaming device include Gigabit Ethernet?

I don't know the internals of rokus or roku TVs, but a lot of the cheap 'system on a chip' designs put the ethernet connection on the USB 2.0 bus which is going to limit bandwidth even if they did use a gig ethernet connection.    So, while I agree that everyone should be using gigabit ethernet connections I expect it to take a while for a redesign and to cost a lot more in the end.


True, the are all SoC systems for the most part. I've never opened up a Roku to look at them, but I'm sure the networking is all contained on the chip. And you're right, it will take a redesign to support higher speeds. But you have to remember that Roku devices are and always were Internet streaming players first. Home media came about when Plex added a channel for Roku, then Emby (I'm assuming it was in that order). Roku then decided to create the Roku Media Player, which supports both USB and DLNA network playback. But they didn't add codec or container support to really make it a "good" local media player. 

I'm encouraged by the effort that Roku is again making with RMP, as it went through a quiet point when the previous developer retired from Roku. But I think they will continue to put the effort into it, and hopefully upgrade the electronic internals to support local UHD playback.

Re: Why does no Roku streaming device include Gigabit Ethernet?

This is entirely false.

It's true that you'll never get near 100Mbps streaming from Hulu or Netflix, even for 4K videos.

But large streaming services all use well compressed H.264 or H.265 videos, with many CPU-heavy options turned on for the best compression ratio.

Local on-the-fly compression that needs to be compressed realtime is not going to get anywhere near the same compression ratio, your CPU can't manage it, especially in 4K.  For example, Rokus all support Miracast where you can have any Windows 10 PC and some android phones stream to it as a monitor.

Uncompressed 4K HDR = 3840 (horizontal) x2160 (vertical) x48 bits per pixel x 30fps = 11.9 Gbps.  There are also 96 bit per pixel variants and this of course doubles for 60fps.  That doesn't even include the audio.

Yeah, of course Miracast is compressed so it isn't really going to saturate 11.9Gbps.  But it isn't guaranteed to maintain a 119 to 1 compression ratio to stay within 100Mbps for realtime compression either.

Also, as others have pointed out, UHD blu-ray is spec'ed to support encoding rates up to 128Mbps.

Not sure who you were replying to. I never stated that online media sources stream anywhere near those speeds. Netflix tops out at 16 Mbps with their UHD material, and Vudu and Amazon are around the same. But my local media (ripped BD and UHD discs) can easily exceed 100 Mbps, with peaks approaching 160 Mbps or higher.

The streaming services fake 4K won't saturate a 100 Mbps link. But if you try to locally stream a 4K Blu Ray quality file it easily needs more than 100 mbps

Re: Why does no Roku streaming device include Gigabit Ethernet?

At the end of the day, I am a very happy Roku shareholder. If they want to be the  "be all end all" of streaming devices, it would make sense for them to spend a couple pennies more to put in a gigabit ethernet port or at the very least, support advertised wireless 802.11ac speeds.  Neither of these things is very expensive and can be achieved cheap devices.

At that point, there is very little need for any other streaming device. Especially when HDMI 2.1 becomes the norm in TVs and devices and eARC is available.

Re: Why does no Roku streaming device include Gigabit Ethernet?

My bet is we are the extreme minority. Most stream from internet sources such as Netflix, Amazon, Hulu, Disney+, etc., and the current Roku is plenty for that. My guess is a cost vs benefit analysis has been done and it's not worth it financially. I hope that some day it is.

Re: Why does no Roku streaming device include Gigabit Ethernet?

Just a thought. The new major development that we will be moving into this summer is all Gigabit up and down. As more new developments are planned and built looking ahead Roku needs to realize they need to get in the market. I have five Roku devices all of which will be trashed when I move. Granted they did their job and four are several years old, but, once I move away from them I am less likely to go back in the future. Just a thought.

Except for playing media from a local server on your own network, that is nothing available for streaming on the Internet that taxes a Fast Internet connection, let alone requires Gigabit. There currently is zero demand for an online streaming player to require a Gigabit connection. I have a Gigabit network n my home, but there are still many devices that don't support it. Networked printers and Smart TVs for example. You can't get either with a Gigabit network connection. Since a Fast Ethernet connection works just fine on a Gigabit network, why would you throw away devices that still work just fine on your new network?

My Shield players have Gigabit, but the only reason I bought them was for local media playback. My ripped UHD movies need a faster connection. If I wasn't streaming from my home server, I never would have gotten them, as the Roku does everything else I need for online streaming.

I agree, there is no reason to pitch your Rokus.  I have a Shield in my main media room for streaming UHD movies but Rokus or Roku TVs in other rooms.  They serve the purpose quite will for the family.

If we need to watch one of my UHD blu ray back ups, we just head to my media room and the Shield runs the show.

Re: Why does no Roku streaming device include Gigabit Ethernet?

I agree it would be silly to get rid of your existing Roku's unless you are consistently watching UHD rips, but it is disappointing they sell a unit called "Ultra" and it doesn't include gig ethernet. In my opinion the Ultra being their top of the line device should have both 802.11ax (Wifi6) and Gigabit ethernet. In fairness Roku is not alone in this. I have 2 different $3000 UHD televisions which do not include Gigabit ethernet or Wifi6. For now I will most likely get a shield or apple TV for our main television to be able to play UHD rips but that isn't the point. I prefer Roku's straightforward interface, app library, and intuitive easy to use remote. It would be nice if they got with the times.
