I have a pretty complicated task at hand, and am wondering if my idea would be a possible solution.

=========
Background
=========

I recently moved into a brand new 3 bedroom apartment. I have a Satellite Dish and Digital Decoder (let's call this Decoder A), with an HDMI out port, hooked up to my large screen Samsung LED TV installed in the living room.

I have another Digital Decoder (lets call this Decoder B), connected to the same Satellite Dish and located right beside Decoder A, also in the living room.

I am unable to place a Satellite Dish in any of the rooms, due to the rooms being located on the South side of the apartment. And the Satellite that I need is on the north of the apartment. Plus I don't want to run the LNB's Coax cable from the living room, through the house to the rooms.

======
Problem
======

My problem is that I don't want to run cables through my house to the various rooms. But I need the HDMI signal from the Decoder (either A or B) located in the living room. My decoder does not have a Cat/RJ45 port.

=======
The Need
=======

I would like to have satellite TV in all 3 of my rooms. But for the purpose of this post, I will limit the need to just one room for the moment.
Therefore, I would like to take the signal (without laying Coax cable across the house or trunking etc) from Decoder B to my bedroom and have it hooked to the Philips LED TV in the room 1.

=======
The Idea
=======

I would like to use a "HDMI Extender" (http://www.aliexpress.com/item/Wireless-HDMI-Extender-S...) such as the one on this link, together with a "Powerline Adapter" (http://www.tp-link.ae/products/details/?categoryid=1658...) such as the one on this link.

Would this set-up work, and solve my problem? I would appreciate any and all advise.

Those device are incompatible. Although they call it HDMI over ethernet it is not really ethernet. It just happens to transmit the signal over cat6 cable.

What you really want is called HDMI over IP. These devices run both on ethernet as well as though a routed network. Now you can likely hook these to powerline network devices but I have not researched how much bandwidth sending say uncompressed 1080p with all the tcpip overhead takes. The powerline units are nowhere close to the so called 500m or whatever they claim lately.

Thanks Bill001g.

I looked up HDMI over IP and the products online appear to better suite professional/ industrial needs, and equally expensive.

I would love for someone who may already have these bits lying around at home to test out this theory :)  .

Thanks again,
Serge

You can hope all you like but that product does not work they way you think it does. I would not even think to order from aliexpress they have the word wireless in the add and the part number is not even correct.

This is the same device from amazon
http://www.amazon.com/Portta-PET30DP-10-Inch-Extender-C...

Look at how many bad reviews this product has and all these people are using 2 physical cables and can't get it to run.

Thanks for that.

Would this extender be a better fit?

If so, would the next challenge be to hook it up to a Powerline Adapter? Or am I being ignorant of further technical considerations?

That also says it runs on 2 cables. The key thing here is they are using the same cables you use for computer networks but they are using it to transmit HDMI signals. The signalling over the cable itself is HDMI not ethernet frames.

So upon further looking I found this.

So lets assume you found some box that you could connect a HDMI and it would encapsulate the data into IP packets. This article claims you need over 6g of bandwidth to accomplish this at 1080p. You will be very lucky to get 100m out of the powerline units.

I understand Bill. Appreciate the research and links so far.
I am going to abandon this approach, and look at possibly trunking Ethernet cables instead.
Thanks again.
