Tv Over Cat5

Theta

Hi,
I was wondering if anyone knew about distributing analogue tv (from a coax input) over Ethernet?? I have seen in done in a house of a friend of a friend! He was an electrician and had distributed all his TV in his house over cat5. It it included his Basic TV NTL and digital. Which I presume is just distributed with the analogue! He said it was easier cause he was wired for Ethernet anyway and it gives a better picture! Having gigabit Ethernet in my own house I was wondering how it was done! I know you encode the coax to cat5 then switch it over the network to an end point which converts back to scart then into the tv or back to coax into his digibox. Can it just be switched over a regular tcp/ip network or does it need a dedicated AV cat5 switch?? Without getting into IPTV encoder's which are quiet expensive!!

Any Help would be great!

yes.
Blackbox, Maplin, others etc sell them.
Google

You can get different versions for
VGA (PC to cieling projector)
Composite
S-Video
RGB

Expensive ones will drive TV video up to 2km. 1920x1200@100Hz video up to 200m on expensive ones.

Plenty out there.

It uses "baluns" to put a singla down each twisted pair. So RGB or VGA leaves no pairs for audio as it needs 4 pairs. (RGB and Sync).
Composite and s-video models allow audio

No ethernet is involved. Entirely analogue magic using the wiring and a box full of "baluns" at each end. So won't work through a switch.

RF (TV aerial coax signal) not sensible over cat5.

STP rather than UTP is recommended.

Hi Watty,
Sounds like you know what you're talking about. Maybe you can help mo out!
I've moved into an apartment which is wired throughout with CAT 5 cabling. The provider is like smart telecom providing VOIP phone, bb and TV via a LAN from the main line into the apt.
I want to get an Eircom line in and then sign up to NTL TV, BB and phone and I'm wondering if I can distribute them via the CAT 5 cabling in the apartment. If I can how is it done / what equipment do I need?
Cheers!

Ok, a couple of questions first:

1) Where are you located?

2) Does Smart not have exclusivity in your development?
In other words is there even a Eircom phone point and NTL cable point in your house?

If no, then you can't get Eircom or NTL and will be stuck with Smart Telecom for everything.

If your lucky enough to have a NTL point in your home, then you can potentially get TV, BB and even phone from them, don't need Eircom.

If you can get NTL, then yes, you can probably use the CAT5 network in your home and setup a network to distribute the BB to all rooms. You might even be able to also distribute the phone over ethernet, but not worth the hassle, just use wireless phones. If you are using the CAT5 cable for BB, then you won't also be able to use it for TV, unless there are two CAT5 cables going to every room.

Of course you could run a media server over your network, to view TV, etc. in different rooms.

This is actually very easy and I have all my AV Equipment both Audio and Video distributed on Cat 5 you can USe Cat 6 also. You can also distribute HDMI on Cat but you need two cables to each point. All the equipment on the network can also be IR controlled from any point. So in my case the video and Stereo are at one point and I have distributed these outputs to TV's and Amplifiers around my house. The amplifiers run the speakers in the Kitchen etc. These too are controlled via Cat so that any device can be listened to and selected via a remote control. If you want you can contact me via boards and I can let you know were you can get the matrix to run this system.

The difficulty usiny Screened cable is the screen needs to be very well grounded as it can act as an interference itself due to induction from other sources. I use non screened cable and having installed many UTP AV Systems over Cat I have encountered no problems other than flat batteries in remotes.

The loss over Cat is so minimal in a normal installation that it is not worth worrying about. AV on Cat is much superior than coax, but it does require a matrix and as one subscriber said requires a piece of equipment which is not just simply a balun which balances the impedance difference between the 75 Ohm in coax and 300 Ohm in Cat.

Yes, a good matrix will cost a few euro, but think of this.

The bitterness of poor quality remains long after the sweetness of low price is forgotten.

So if you wish to distribute HD or normal AV get equipent that will work simple as that.

Hi gmoyne,
I am looking for an AV Matrix or a repair for a Scion pro-1000 16x16.
Could you direct me to some Dublin based company or techy?
Thank you in advance.

gmoyne

You can call me on 086 2339430

have a few questions
do you need a server running all the time to use the services
depending on the box you buy, each cable out of the port from the ip box can travel 200m yea not all the ports in total,
cat 5 cable can travel 90m from each port yea on a standard digital network
can you use one single cat 6 for hd

Q. 1 Only powered , but not on when not in use.
Q. 2 NO !
Q. 3 NO ! you need two !

sean2012

so the server or laptop doesn't need to be connected to the system once it has been setup, just need the box on? yea

you need 2 cat 5s for hd ? yea, is there a box with 2 ports for hd (transmit receive)

and 200m on each port? yea
can you put more than one tv on each port? no

if you had 3 or 4 security cameras around your house, you could put them on the system as well? yea

what would be needed to record the security cameras?

gmoyne

Everything depends on what it is you are hoping to achieve ?

If you are using the matrix manufactured by Avnex all you do is connect what every source you wish to the inputs. There is no setup really other than knowing that you have plugged a device into 1, 2, 3 etc. One attached the TV or what ever other out put you use such as surround sound is switched on and the no. of the device is pressed on the remote. ie 1 of video/blue ray etc. No. 2 for radio/ cd player etc.

The matrix is simple and you can have as many inputs or outputs as you wish.

I have in my own home 3 inputs TV, Satellite and Radio/System. On the radio I have a USB input with a media player attached.

My out puts go to three zones Sitting room Bedroom and Stereo Amp for surround Sound.

If you have any other questions just ask !

sean2012

so everyting above is right yea?

i know woodcomm in ballymount industrial estate have these systems for sale,
not sure which box's they have thou thanks

Hi,

I have one room in my house that doesn't have a coax tv point but I have cat5e in this room and all other rooms in the house. I want to be able to watch standard tv in this room and want advice on what I need to do??

I also have a hub where all cat5e and coax cables are fed back if that is of any use?

MHI

If your looking to distribute hdmi over a single cat5 cable the HDanywhere multiroom+ system 4x4 is exactly what you are after, supports 1080p HD & 3D and also IR control and also has Ethernet port on the receiver so you can use your smart tv to its full potential without the need for dongles or any long runs of wire on show, you can store all your source equipment in central closet and distribute to 4 rooms and have full control over IR, drop me a pm if you want any more info.

BMD

Hi, thank you for the reply. I had a look at your suggestion on line, I couldn't see prices but it doesn't look cheap. Given that I only want to watch standard tv (no Internet, 3d etc.), is this perhaps over kill and is there a simplier solution?

Connecting coax to cat5 there is a dogsh*t cheap option to carry signal over from one to the other. Strip back the coax 1 inch. The woven copper is either the - or + and the copper core is the other - +
Get cat 5 cable strip back and connect a wire to the woven end and another around the core. Duct tape

Babi-horse,

Apart from the very dubious suggestion for coax/cat5, resurrecting a query from over 4 years ago is not welcome.

Thread closed.
