Streaming PC signal to PI using power line adapters.

[arnoldpl]

Hi,

I am trying to mirror the PC screen to Raspberry PI using power line network adapters.

So, PC-->Power Line Network Adapter <-------> Power Line Network Adapter -->Raspberry PI ---> Monitor

Is it possible ?? Can anyone advise please??

Best regards
Arnold

The powerline adapters are transparant. It is like a dedicated wire.

What you want can be done with VNC. Server on the PC, client on the Pi.

You might have to solve some network problems since I do not see a router in your network. This is not a showstopper, but both PC and Pi will have to be assigned a static IP. Something like 192.168.1.1 on PC and 192.168.1.2 on Pi. Mask something like 255.255.255.0 and you will have to use ip numbers to access the other computer.

I use powerline adaptors to stream to my pi.. works great.

I'm not a very big fan of the powerline adapters. They won't work if they're attached to a surge protector or a UPS, they won't work if the circuits are on different phases, they won't work if the outlets are electrically isolated from each other in the circuit breaker panel for some reason. If the breaker is a GFCI breaker it can create problems, fans, Compact Florescence lights, motors, and switching AC/DC power supplies can all cause data interference. The list goes on.

That said, many people do use them quiet successfully, I just don't like them because of all the many things that can interfere with reliable data transfer and break communications all together.

Instead I really enjoy using MOCA adapters. I followed the advice over on this thread in another forum for using two verizon routers as a MOCA bridge to transmit Ethernet over Coax lines. A quick summary is:

The device we're using is the Actiontec MI424WR. Find one that is at least Rev. D. The newest Rev is a gigabit router with Wireless N. MOCA speeds will be equivalent to 100Mbps Ethernet (I tend to get just north of 100Mbps using two devices).

There are two limitations of MOCA

1) You have to have a coax connection nearby, but many modern homes have a coax adapter in almost every room
2) It uses frequencies greater than 1000 Mhz for data transmissions. Satellite also uses this range. So MOCA 1.0 is incompatible if you're using Satellite, you would need to use MOCA 1.1 or MOCA 2.0 (MOCA 2.0 exists, but I haven't seen anyone using it yet). Starting with Rev F the MI424 uses MOCA 1.1 so you could use that with Satellite.

MOCA is as rare as hens' teeth in the UK.

http://www.dlink.com/uk/en/home-solutio ... dapter-kit I have used these at home
[currently not avialable in the UK dunno why]
the current system goes from near my hub in the front room,
though the consumer hub 2 rooms away
to the outbuilding circuit
to another consumer unit out there
to a plug socket hanging off the wall

no issues - get decent rates

All of the mi424wr models can do MOCA (though I recommend using at least REV D). It looks like I could find two of these adapters for about 25 dollars(GBP) shipped. Also you can mix and match revisions, so I rev I. will work with a Rev d. etc.

Once you have a working network connection (over powerline/MOCA/wifi etc..) desktop streaming should be possible.
(Warning: shameless selfpromo stuff)
I recently made a tutorial on how to setup screen mirroring between PC and pi over network with a relative low latency (about 700ms over wifi). You can see it here if you want: http://www.raspberrypi.org/forums/viewt ... 35&t=89605
