cat5 to tv problem

[tpwuk]

I assume he's trying to setup an Ethernet network to distribute his boradband connection around his house, as opposed to using Cat5 with HDMI extenders to distribute HD signals. Ethernet data and HD signals are different.

Like he said ^^

ohhh.... I see..

I'm assuming he was passing data streams down his ethernet, that data = video stream.. so it's data.. but I see your point - I don't know whether you can pass HDMI down ethernet...can you?

Yes, you can pass HD signals down Cat5 or better still Cat6 by using HDMI Extenders. The use of Cat5/6 cables allows for greater cable lengths in HiDef applications.

I guess I was guilty of using loose terminology- what I meant was transferring data streams which contain video information from the internet This is pretty intensive continuous data transfer and I was wondering if the posters hardware/cabling was up to the job?

 

[tpwuk]

I'd say 12m runs of Cat5 is more than adequate for distributing broadband, however these days I would always use Cat6 no matter what.

i can access the media centre option on the panasonic tv to access the hdd on my pc,that way i can play the dvd's and audio stored on the hdd through the tv/surround system.
i was doing this through the playstation wireless but could only watch at single speed could not fast forward,with the laptop connected to the tv i can fast forward up to 30 speed without a problem.
when i sort this out i should be able to watch audio/video/cable on all 4 tv's around the house.

Sorry is this thro the 12 Metre of cat5 cabling you are accessing the hard drive?

 

[mercmanuk]

yes the the cat 5 will connect to the tv and the router or ethernet switch

 

[Noodle-Pulp]

Odd question - does the failing connection work ok if you take one of the other cables out of the loop? (yes, yes.. I know it's not token ring, just a turn of phrase...)

 

[mercmanuk]

if i connect either of the 2 cat5 cables i have going to the tv/playstation directly to the router i have nothing on the tv but the playstation is ok.if i change over the tv/playstation cables still nothing on the tv but the playstation still works proving both cables are ok.
if i extend the modem supply cable allowing the modem to sit next to the tv and use a 1m cable the tv works fine.
pulling my hair out "what ive got left"

Doesn't this suggest again that the problem is somehow something to do with the overall length of your network, or am I barking up the wrong tree?

 

[Ted]

Token ring! that takes me back!

 

[mercmanuk]

cat 5 is good upto 100m as a rule of thumb

I know... but it looks like you reduce your overall length and see that it works fine? That's all I keep coming back to....

I have read- not sure where that data consisting of uncompressed video requires better quality cable. My guess is that that the envelope or rate the packets of video data are delivered for IP TV are different than those generated via your computer = same type of data but "packaged "differently. Due attenuation or poor noise rejection or timing issues ---whatever---- this causes sufficient signal degradation to cause the system to hang up. Packets of video data are a particular demanding type of data which "wants" to be one way compared to the "to and fro" type of communication protocols computer generated data uses so may be more demanding in some particular performance aspects than the usual ethernet communications??
ps I'm not explaining this very well hopefully some network guys can shed a bit more light with better terminology

What's the modem for?

 

[Noodle-Pulp]

What's the modem for?

I suspect it'll be a standard cable modem as supplied by Virgin Media or somesuch...

 

[mercmanuk]

virgin media modem for internet access connected to a netgear router

 

[tpwuk]

Are all your cat5 cables attached to this cable modem? How many ports does the modem have?
