USB to Ethernet conversion using adapter

[stein.tommer]

hello all, hope i choosed the correct Category.
i'm an electricity engineer student and i'm stuck with a project (Mux and Demux of 4 Digital Video channels)

i have few things i don't understand, if someone will be able to help me and explain some to me it would be amazing!

1. Ethernet Protocol (also be glad if you have good datasheet to get more info about)
2. USB to Ethernet (How does it work? how the data converts from USB to Ethernet? and if you have a good datasheet i can absorb more info about)

just to be more clear. i'm about to use 10/100 Mbits Ethernet protocol for my project. and the USB to Ethernet part is going to be with USB 2.0 if that is important for helping me out.

appreciate any chance for help! any information will be good!
thanks from ahead for the helpers

Not familiar with USB to Ethernet, but perhaps this will help:

https://ieeexplore.ieee.org/browse/standards/get-program/page/series?id=68 (802.3 section)

Have a browse through that lot for anything pertinent. It's a bit dry though. Try:

https://www.lantronix.com/resources/networking-tutorials/ethernet-tutorial-networking-basics/ (see parts 2 & 3 too)

Soak up some of the terminology applicable to you, and go hunting for what they all mean. Also suggest you familiarise yourself with TCP/IP stack, OSI model and so on. Lots of reading.

Each of your topics is multiple PhD thesis's each...

There's no such a thing as "Ethernet Protocol". Search the 'net for OSI Layers (and Ethernet is one of the options for one of the layers), this is what modern networking is based on.

As for USB-to-Ethernet - it's another way to provide Ethernet connection to a host.

And to be honest, I have no idea how this will apply to your Video mux/demux project. "Digital video" means nothing until you start speaking about specifics. If you need help, start by defining what is given and what you have to do with it.

i look for both of them, thank you. i know its alot to read, hope ill manage to do this on time
ill check your links now and for both models you said so

thanks for reply.
USB to Ethernet is only gonna be an adapter to transfer DATA in to NVR. that is why i need to understand how the data will transform from USB packet to Ethernet packet.
i look for OSI and search over there. any good website to get data from?

You have a lot of reading ahead of you... It seems that the "source video signal" comes over USB, and you want is **somehow** transferred over Ethernet to your NVR. That's not the way Ethernet-to-USB works.

Ethernet-to-USB adapters have the task of providing Ethernet frames to a piece of software in the PC (the driver) which will pass them to the PC' network stack. There is no fundamental difference between a ISA/PCI/PCIe Ethernet adapter and its driver, and Ethernet-to-USB adapters - in both cases Ethernet frames from the cable are transferred back and forth (thru the driver) to the host' Network stack for further processing.

Please clarify your project - what is/are the source(s), what is/are the destination(s), what sits between, and how they are connected.

thank you again for reply.
i hope you received my private message, i'll be able to be more clear about the project
