HI guys, this is only my second post so go easy! haha

I'm having noise issues with my Cambridge Audio cables, watch Transformers i get a lot or graining or fuzziness, unsure of the correct term, suffice to say i'm not happy!

I'm currently running a PS3 as my Blu Ray player, a Pioneer VSX920 amp and a Samsung PS50C680 50" 3D TV

So im after new cables don't think the Cambridge Audio cables are up to it!

current cables....
http://www.cambridgeaudio.com/summar...0HDMI%20Cables

they were on £50 for the pair, guessing ill be paying at least that each now!

I need the to be 1.4a/high speed ethernet due to the 3D factor!

what would you guys recommend!

Cheers

Hmm. I think I paid about £2 for my cables and they do 1080p 3D with no problems at all...

I'm not sure what artefacts you are seeing, or how they could possibly be cable-related. All I can suggest is that you cut the amplifier out of the loop, to see if that has any effect.

Isn't the PS3 only HDMI 1.3?

It has enough processing grunt to push the required amount of data over the cable for 3D. What it can't do is HD audio at the same time.

The point is a cheap 1.3 cable is all that is needed for a PS3.

OP - have you tried connecting the PS3 directly to the TV?

I had a Pioneer amp which, when a bluray player or ps3 was connected via HDMI had handshaking problems but both worked perfectly well when connected directly to the TV.

I would get the HDMI 1.4 myself with the ethernet capability ................ never mind the 3D malarky

I have these and they are good to me

There is absolutely no point in getting an "HDMI 1.4" cable to connect a PS3, given that the interface on the PS3 is only HDMI v1.3a.

All you need is a "High Speed" (Category 2) HDMI cable without Ethernet, aka an "HDMI v1.3" cable.

You also really do not need to waste money on expensive cables. It is utterly pointless, and any perceived improvements from using £50 or £100 cables are merely due to the cashebo effect.

See this for Digital Foundry's take on expensive HDMI cables... http://www.eurogamer.net/articles/di...oundry-vs-hdmi

it depends how you see it. You could get a normal HDMI and it will play all day long, or spend a wee bit more and re-use the cable later for higher bandwith and internet .................. we are not far away from only one device connected via ethernet and all other devices will use HDMI to connect to the internet

it all depends on the cash available

HDMI Ethernet Channel

What will I be able to do with an HDMI Ethernet Channel -enabled device?

The HDMI Ethernet Channel enables a number of new possibilities via the HDMI link, including:
•Sharing an internet connection– The HDMI Ethernet Channel feature allows your internet-ready entertainment devices, from gaming consoles to Blu-ray Disc players and more, to share an internet connection without any need for a separate Ethernet cable.
•Content distribution– Devices connected by the HDMI Ethernet Channel will be able to exchange digital content in its native format, enabling recording, storage, and playback options across a connected system, with no need for a separate Ethernet cable.


•Home entertainment networking– The HDMI Ethernet Channel accommodates current and future IP-based networking solutions for consumer electronics, such as UPnP, LiquidHD, and DLNA. HDMI with Ethernet is the ideal one-cable solution for connecting devices in these advanced home-networking environments.

What network protocols are supported over the HDMI Ethernet Channel?

The HDMI Ethernet Channel feature supports any networking protocol that can run over an existing Ethernet connection, including TCP/IP, UPnP, DLNA, LiquidHD, and so forth.

What is the maximum available bandwidth of the HDMI Ethernet Channel?

Up to 100 Mb/sec of bi-directional (full-duplex) bandwidth is available over the HDMI Ethernet Channel.

Will devices connected via the HDMI Ethernet Channel be able to share an Internet connection?

Yes. Provided there is a routing device somewhere in the network – either a stand-alone router or a device with integral router functionality – the HDMI Ethernet Channel will enable linked devices to share an Internet connection.

Will content distribution and recording be possible in a system connected via the HDMI Ethernet Channel?

Yes. The HDMI Ethernet Channel allows connected devices to share digital content in its native format. For instance, if it is protected by HDCP encryption, it will stay in its encrypted format, and can only be accessed if all the devices in the system are HDCP-compliant. Unprotected content, such as digital HD broadcast programming or user-generated HD video, will of course be free of any content protection.

Will I need a new cable to support HDMI Ethernet Channel functionality?

Yes. The HDMI Ethernet Channel feature will require a new type of cable, either a Standard HDMI Cable with Ethernet or a High-Speed HDMI Cable with Ethernet, depending on the maximum resolution to be supported

Grain is part of the picture.
Fancy cables don't make a difference, it is digital.

Your harddrive cable isn't 50 quid.

Neither should y our hdmi unless you are buying 30 meters worth.

Yep, it's the digital cliff, a better made cable will work over a slightly longer distance, that's all.

Either it works, or it doesn;t, but you can't get a "poor" picture.

hdmi 1.4 is not required for 3D. It is however required for the TV to auto switch to 3D when it's present. Without it you simply have to tell the TV it's 3D . Given a 1.3 source it's totally pointless. For a broadcast source there's no additional bandwidth required, even the first hdmi spec is adequate.

The only problem I've had with cheap HDMI cables are casing falling apart. as long as you don't go as cheap as 1p from amazon I sure you will be fine.

Can any explain the Ethernet part of hdmi 1.4 ? I don't see how it works are current TV's taking use of it ?

Basically one device would be connected to your broadband router by whatever means. That connection can then be shared between all the other devices connected to this one via HDMI.

Saves having to run three or four Ethernet connections back to the router if you have several network capable devices.

Not sure though just how much kit actually makes use of it yet.

Nope. The Ethernet part of 1.4 is just for Internet stuff. Your cables look good so can't see why it would developed a fault. Connect your PS3 to your TV directly and see what happens. After that check your amp.

As said above nothing at all to do with video transmission.

In any case it is not the cable alone that determines if the system runs at 1.4 mode. It requires the devices at each end of the cable to be 1.4 capable as well.

So if you have a 1.3 source device it is completely irrelevant if you use a 1.4 cable or not, it won't make use of the extra facilities in the 1.4 spec. Similarly for a 1.3 only destination device.

HDMI Ethernet Channel (HEC) is not backwards compatible with older versions of HDMI (1.3a or below) as it uses a previously unused pin on the HDMI connector.

It also isn't directly compatible with conventional ethernet as it only uses one twisted pair whereas conventional 100Mbps ethernet uses two twisted pairs. Instead it is a 200Mbps half duplex protocol that emulates a 100Mbps full duplex protocol using software emulation at each end, so only devices specifically designed to use it will be able to do so.

On a side note, the reason the PS3 can't output HD audio at the same time as 3D video isn't down to the HDMI hardware or firmware. Sony, as one of the designers of HDMI, had foresight to give the PS3's HDMI firmware a degree of upgradeability which is why they've been able to upgrade it to partial 1.4 to implement 3D output. HDMI 1.3 and 1.4 have the same peak throughput of 10.2 Gbps (after overheads).

The real reason is that the PS3 is running flat out when outputting 1080p 3D and there isn't the processing power left to deal with the HD audio signals. The clue to this is that several other BD features are disabled when in 3D mode, including enhanced interactive disc menus and features.

(This isn't a dig at the PS3 by the way. It's impressive that hardware designed 5 years ago is capable of outputting 1080p 3D at all.)

it is backwards compatabible in the sense it works with HDMI right now , as mine do

If you can get 1.4 at a good price , then get it . If not stick to £ 3 to 5 a cable

You're using an HDMI ethernet connection on a pre HDMI 1.4 device? Very unlikely, but please enlighten me. What hardware is it?

He means it carries picture and sound. That's a perfectly valid statement, as you well know.

Ahh yes! I see now that Niall has mis-interpreted my comment regarding backwards compatibility, which I was aimed solely at HEC.

The HDMI 1.4 cables and standard AV connections are of course backwards compatible with older versions of HDMI.

when we can see the ethernet capabilities is another thing .

I try to see it like buying USB 1.0 cable when USB 2.0 was out . And now USB 3 is here ! Its trying to work out how much you should pay to future proof yourself , without wasting money .

I hope it takes off , I think it would be quite handy

Paying £50 now for a lead that is no better than a lead for £1 in the vague hope it 'might' be useful in the future seems more like wasting money than anything else

Buy a lead for £1 now, and then (5-10 years in the future) buy a 1.4 lead if you need to, which will probably only be £1 by then anyway.
