I love seafood but I am not a sifu, only someone who knows a little.

Are you using SAROWIN HD-10 Wireless HDMI Transmitter & Receiver Kit ? You did not mention what brand.

Anyway, it does not matter what brand you use because the connections should be the same. From your explanation, that means you are using 3 different component units... 1 transmitter unit, 1 receiver unit and 1 switch unit.

As they say, a picture is worth a thousand words so I have drawn this illustration graphics to show you (inside spoiler)...

Actually, different brands call the transmitter, receiver and switch units with different names but I think you can easily identify which is which from my graphics shown above.

If you have the Sarowin HD-10 Kit, there is also a fully compatible Sarowin HDMI Switch (4 In/1 Out) which can directly be joined together without extra HDMI cable connection.

Since you mentioned that you are using an HDMI Switch (3 In/1 Out), that means you are not using the Sarowin HDMI Switch (4 In/1 Out).

You did not mention anything about whether your HDMI Wireless transmitter OR the switcher support relay of IR signal which allow you to use your remote control from your master room. As you already know, you can connect 3 different sources such as Byond box, Blu-ray Player, Dune HD Mediaplayer which have HDMI outputs to your Switcher. Do your Switcher have IR signal cable which can be stuck in front of your 3 sources ? Or do your HDMI Wireless transmitter have this IR signal cable ?

If only your HDMI Wireless transmitter have this IR signal cable and connected to Byond, then I am not sure whether you can or cannot use the remote controls for the other 2 sources as shown in my graphics above... only your Byond remote control can be used in your master room. I am only guessing because you did not give very detailed info about your HDMI Wireless transmitter and Switcher.

So there are also the IR (Infra Red) connections which are needed to allow 3 different sources (including Byond) to be used with each of the 3 different sources remote controls in your master room !

I can show the IR connections using the Sarowin HDMI Switcher (4 In/1 Out) as an example...

... as you can see, there is an extra IR cable connection to the "IR Extender Box" which have 4 different IR transmitter cables put in front and pointing at the IR sensor of each source such as the Byond box, Blu-ray player, etc.

The connections become more complicated when an AV Receiver amplifier is also used with 4 sources connected to it and want to share these sources in another room ! Not possible unless the AV Receiver support HDMI signal passthrough when switched off. There are also other methods too, such as using media streamer boxes, network cables, etc. Mmm... I will not explain and just leave this out now, hehe.

I hope I did not confuse you with my explanations. Actually you should ask the person who sold you the HDMI Wireless transmitter and a switcher for help because that seller is the best person who knows the product well. Also, many people may not understand the manual or... hehe... many don't actually read it. I always read all my product manuals when I purchased them.

If you have anymore questions or anything you still don't understand, you can ask me again BUT please give more detailed info about your units. I cannot promise to be able to answer everything correctly and may be late a few days to reply. Hope I have helped.



ADDITION
I almost forgot about 3D ! Assteruk sometimes broadcast live football matches in active shutter 3D. If you have a 3D HDTV, you can watch such "3D" matches. Also, 3D blu-ray player also play 3D blu-ray discs. BUT all the equipment must support HDMI 1.4 standard so if your HDMI Wireless transmitter and switcher is only HDMI 1.3c ready, then you will not be able to get 3D in your master room with a 3D TV ! There is also a sync signal for left and right eye that need to be relayed too and HDMI cables that support the HDMI 1.4 Standard must also be used.

Yes, I understood what you meant when the Sarowin HD10 Transmitter have only 1 HDMI In, NO HDMI Out. I do not have the Sarowin Kit and did not read more info on it so I downloaded the Sarowin manual and read it.

I will redraw my graphics to show different connections which uses only 1 HDMI IN to the Sarowin Transmitter.

Ok, I have redrawn my graphics for the connections (inside spoilers)...

Since your Sarowin HD-10 Transmitter only have 1 HDMI IN, the HDMI Switcher (3 in/1 out) cannot be used because you need to connect your TV in the living room too. Refer to my redrawn graphics and you will see why you need to have a Switcher with 3 In/2 Out !

Here is another graphic showing the actual Sarowin Transmitter (1 In only) + Sarowin (4 In/2 Out)...


According to the Sarowin manual, the Sarowin HDMI Switcher actually have 2 HDMI out... one connect to the Sarowin Transmitter and one connect to the TV.

Mmm... are there other brand HDMI Switchers that have 3 In and 2 Out ?

From the manual, the Sarowin Transmitter also have IR sensor BUT I am not sure whether all the remote controls can work or not for all 3 source (Byond, Blu-ray Play, Dune HD Mediaplayer) connected to another brand HDMI Switcher (3 In/2 Out). You may find that your 3 remotes cannot be used in your master room with the Sarowin Receiver. This is because you need to have the Sarowin IR Extender box (with A/C adapter) to connect 3 IR signal transmitter cables with the Sarowin Switcher. Sarowin is very clever because the Sarowin Transmitter do not have IR port to connect to the Sarowin IR Extender box, only the Sarowin Switcher have the IR port connection.

So... you cannot use your other brand HDMI Switcher (3 In/1 Out) and there is no IR port at the Sarowin Transmitter. Only after you are completely satisfied with only 1 Byond connection to your Sarowin first, then you have no choice and my best advice is for you to grab the Sarowin HDMI Switcher which comes together with the IR Extender Box and all the IR transmitter cables. I guess you can use the other brand HDMI Switcher (3 In/1 Out) for other purposes.

I hope I have finally answered your questions.

No problem to ask any noob questions as nobody knows everything, including me. 

I don't think your 3in-1out HDMI switch able to perform what you want to do. You need a HDMI splitter such as 1in-2out or the Sarowin 4in-2out. This way 1 output goes to TV and another output goes to Sarowin transmitter.

How much did you paid for the Sarowin HD10. I was thinking of buying the same but found that Winstar WS-AV511SR is the same design but much cheaper than Sarowin.

You are welcome. Glad to help. 

Yes, you have no choice so buying the Sarowin Switcher is the best option in my opinion because of the IR signal connection for the remote control. I think your total cost will reach RM 1000+ when the Sarowin Switcher is included. Not sure about the actual price now for "everything included" in the Sarowin kit.

Yes, 2 HDMI Out is required for the HDMI Switcher. Refer to my graphic which I later posted showing the Sarowin Switcher with 4 In / 2 Out.

I do agree that we have to be careful when choosing cheaper brands which may not be reliable so making sure is important.

Mmm... if you can.... return... your Sarowin kit to the seller... its better to look for a cheaper option that can provide the same HDMI features AND must also be reliable and have reasonable quality. It may not be easy to find a good and cheaper alternative. Mmm... I don't think the seller will allow any return, which is fair for any purchase, unless the seller earlier agreed to let you test it first, hehe.

Kimyee73 have replied and suggested Winstar WS-AV511SR. No harm to check this brand out but I am NOT suggesting that you buy it. I don't know anything about this brand so I cannot make any comments. Kimyee73 knows much more than me about this brand.

Whatever, only my personal opinion to choose other brands because I know nothing about them ! 

ADDITION - Winstar WS-AV511SR
Kimyee73 is right ! The Winstar WS-AV511SR look exactly the same as the Sarowin HD-10, just like a photostat copy and its selling at RM 550 for the complete set, WINSTAR WS-AV511SR Wireless 5G HD AV Kit w/HDMI Switch + IR (4-HDMI-IN-2-HDMI-OUT). I dare not take the risk to buy online from the malaysian online shopping site which sells this especially when the quoted price is so low. Its easy to find this malaysian seller, just google for it but be very careful of the risks from buying online, especially from unknown sites.

This product is manufactured by Winstars Technology, headquartered in Shenzhen, China. Did Winstar manufactured this product for Sarowin or the other way round ?

ronn77, appreciate if you able to describe more on problem you face when positioning the transmitter and receiver unit such as whether you can place them horizontally in cabinet or you need to place them vertically and have to rotate them around to get a good signal. Also you mentiond the distance of 7m for it to work well, how far is your current upstair/downstair setup. Thanks.
