The aim of this project was to transport both digital audio and power to a speaker using a single Ethernet cable. Transmitter/Receiver PCBs were designed and software written for the L1 64 pin device.
A lightweight software stack transmits audio from S/PDIF over Ethernet, recovers a clock at the receiver and outputs/amplifies the audio using a digital input Class D amplifier.
This project was submitted as a final year project on the MEng Computer Science & Electronics course at the University of Bristol.

Can we get some demo videos up so we can see it working? :D

Any more info about it, like a thesis, github etc ?

This looks brilliant - I notice it's L1 based so really looking forward to seeing how you squeezed stuff in, which protocols you are using, general specs etc. etc.

Do you have something you could upload for us to download and play with? Its something that could be really helpful to the community.

So does this device actually transmit the audio via Framed Ethernet Protocol (DIX/802.3) or is this simply utilizing Cat5/6 8-conductor twisted pair to transmit the signal as well as power to a speaker?

Yes, it transmits audio via standard Ethernet packets. It's not transmitting analog audio across Cat5.

Hi Andy,
 
Great project !
Is AVB compliant ?
If not, are you working on an AVB version ?
