Is the AEM Xtra Link 2 the same one shown in this picture (inside spoilers)...

If its not the same, all my explanations below may be useless. I hope not.

This is a "Made In China" product, lol ! I contacted my helpful online friends and got the above photos found somewhere... I think should be obtained from the internet. Yes... this device also transmit and relay audio+video by using co-axial cables, not network cables. The same type of cable used for the TV aerial and satellite dish.

If you wish to use this device with your Astro decoder, then "maybe" you have posted correctly in this Astro Byond thread. I cannot answer if you intend to use this device for other purposes.... so I will only reply on using this device with the Astro decoder box.

There are many such similar devices available in the market which basically allows us to share the same satellite TV channels on more than 2 TVs. There are many poor quality ones with low specifications such as AEM Xtra Link 2 or higher quality ones which support HD with HDMI port. Expensive ones uses wireless to transmit even HD such as the Sarowin device.

This AEM Xtra Link 2 (same as others) have 2 separate units... (1) the Coupler unit which connects to primary source and sends audio+video using 75 ohms co-axial cables to (2) the Injector unit connected to the 2nd TV.

Mmm... its easier to explain AEM Xtra Link 2 connections using graphics instead of words, as shown below (inside spoilers)...

There is a problem here... if you are using Byond or Byond PVR box ! Both Byond and Byond PVR box do NOT have RF output as shown in picture below (inside spoilers)...

Therefore, you need to connect the RCA out (Red, White and Yellow) from Byond or Byond PVR box to a "Line to RF signal converter box" and then connect to this device. I am not sure but I believe there will be a problem with the IR signal when connected in this way because the "convertor box" may not relay the IR signal to the Astro DMT box so you may lose remote control use in the 2nd room !

There will be NO problem if you use the old Astro DMT box as shown in above picture because it has RF output so its a "direct" connection to the device.

I don't know whether this device use a different RF frequency output from the one used in Astro DMT box RF out. If its different, you must use the 2nd TV to find and lock to the device RF frequency which is easy by using auto search on VHF and UHF wavebands.

Please take note of these points when you use co-axial cables to carry RF signals from the device (inside spoilers)...

I am sure you already knew that many people have been using devices similar to the AEM xtra link 2. Usually many people refer to the device "IR transmitter/emitter" for remote control use as "Cat's Eyes".

As usual, I have explained too much when you only asked "does transmit audio/video or not". I repeat, if its the same device... the answer is... Yes. Sorry for my over-explanation here.

Note: If others find any mistake here, please correct me. I don't mind so that we can give better help to "turion64".

My pleasure. You are welcome. Mmm... I am already hooked on HD and Dolby Digital 5.1, blu-rays with 1080p picture and DTS-HD Master Audio/Dolby True-HD/DTS Hi-Resolution... so SD video and stereo audio is not my preference now. The only analog stereo audio that I will forever love is the audiophile sound of LPs from turntables when I got addicted as a teenager in the seventies !
