HDMI transmission over LAN network

[haisaikat]

Hello everyone, posting here after a long time. I wanted to check if someone has previously tried transmitting HDMI signal ( my requirement is 1080p 2D with HD Audio) over LAN network (wired cat 6) and any pros and cons that I need to be aware of before plunging in.

The background being that I have recently upgraded my DIY NAS cabinet from an existing 15 year old Pentium 3 age cabinet to Cooler Master 690 II Advanced cabinet. So wondering if I can shift the hot GPU of my DIY HTPC into my nas since this is a more airy case. These days my htpc gets summoned less after Amazon fire stick is streaming 5.1 DD output for online content and also supports Kodi. Htpc gets into action only for hd audio scenarios that is less.

I don't think you are transmitting hdmi over lan. I don't think it is even possible. What you can do is transmit 1080p video file over lan which can be played easily over 100 mbps lan connection.
If you want to play 1080p files then raspberry pi 3 can easily do it either through usb or lan. It cannot play x265/hevc files. So, either keep your htpc or use a long hdmi cable or get a rpi3. I would recommend the last option. There is no heat or noise from pi.

Yes you can practical do so by using a HDMI extender extender. I was using a monoprice HDMI extender
https://www.amazon.com/Monoprice-328-Feet-Ethernet-Extender-108123/dp/B00DIKI46Q

I have recently renovated my set up so this is lying unused and is in very good condition and I am looking to sale, if interested pm me.

please PM me about your expected price for the above and for the benefit of this forum, any pros and cons in this approach? Also one important query is can the link via cat6 between the transmitter and receiver blocks be no direct and via a Gigabit switch with other LAN connected wired devices? In essence what i want to check is if the extender can work with a direct point to point LAN cable.

I am not sure why people are posting that this is not possible. This is exactly what baluns are meant for. Using a balun, you should be able to transmit 1080p over Cat6 to about 150 feet wire length. It is just not feasible to run HDMI cable for such long distances. "HDMI Extender" is the non-technical name for balun (which in turn is short for BALanced-UNbalanced)

Note: I haven't used it personally, although I was researching this for wiring up the house.

Edit: Powered or "active" baluns will generally work much better than passive ones. This will help the balun boost the signal and send it uncompressed over the wire.

Also, as I understand, this is not packet switched data (unlike typicaly digital network data). This is a data stream. So it will not work with a switch that basically switches data packets. This will only work if the two ends are directly connected by the same wire. Again, based on my theoretical understanding. The first comment on the Sabrent product review is also helpful.

This is the answer I was looking for . Great thanks

Unfortunately Hfv does not allow editing post after an hour. I made a mistake. I did not think it was possible. But, the product you linked has really poor reviews.

Seems to be something wrong at Amazon's end. If you notice, the link i posted gets redirected by Amazon to another generic extender link. It is a different brand entirely. I was just giving an example of an active/powered balun. Sorry, I do not know enough to make a solid product recommendations except to state the basic requirements that you should go for an active/powered balun over a passive one.

Edit: Generally speaking, the powered ones will be more expensive than the simpler passive ones. You might be better off searching on amazon for "hdmi extender" or "hdmi balun" and then filtering based on reviews and features.
