HDMI over Cat5

[sparer]

Hi,
I'm installing a wired network into my house so that I can stream content to the tv's and so that any smart tv's that I buy will be able to connect to the internet without the risk of rubbish bandwidth over wifi. I'm going to use HDMI to Cat5 converters and wondered whether they use TCP/IP or some other protocol. Id like to run the traffic through a network switch but I can only do this with TCP/IP.

Thanks
Richard

Ok I got my answer by searching around a bit. Baluns dont use IP but there are more expensive devices that do.

Be aware that some converters use two cables, some use one. The ones that use two cables usually have less restrictions as the HDMI cable has a minimum of 5 data paths. With 2 cables these can be accommodated without any conversions, while with only one cable it needs to mux all but the 3 video channels into one circuit.

This. Put in plenty of cable!

I use this type of thing, no problems streaming to my smart or otherwise TV's.

No miles of cable either.

That's OK if you don't mind being completely antisocial in the radio spectrum. They are to the radio spectrum as the antisocial neighbour who winds their megawatt HiFi system in the front room up to 11 so they can hear it at the end of the back garden is to the audio spectrum.

These things are not, and cannot be, compliant with the most basic EMC requirements - but our authorities seem afraid to upset their paymasters (the likes of BT) and have expended a lot of effort in finding excuses for it not being their problem. And don't fall for the industry PR that it's just a bunch of old beardies (radio amateurs) affected - it affects lots of things, including your ADSL signal, the CAA have expressed concern, as have the BBC and others.

It is indeed, while a clever solution to a problem, quite odd that as yet no one has gone 'but thats illegal and about as complient as replacing airbags with spikes' and baned the lot.

Indeed. For some reason all Uk regulators have put a lot of effort into showing why it's not within their remit. In particualr, the RA has put much effort into justifying lack of action on the basis that the devices aren't intended to be a transmitter - even though a fundamental effect is pretty well guaranteed to be lots of emissions due to shoving loads of RF down a leaky feeder antenna !

Other bodies say there's nothing they can do as they meet regs - but only by testing them in such a way as to show compliance when not working. A bit like proving that a light bulb isn't too bright when it's switched off !
