Looks good.

Wenn do you expect this on the market?

Interesting development. I'm very curious how they will manage to transport uncompressed full HD (about 3Gb) over a CAT5e (100Mb) cable, also including control, power, audio and feeds to multiple in-home devices.
But than again, 12 years ago the today's ADSL specifications sounded like science fiction too...

Cat5e = 1Gbps

[Carlo]

What I mend is the 100BaseT Ethernet as described in the article, but even 1Gb/s would not be enough.
But then again, perhaps they only plan to integrate 100BaseT Ethernet into their own infrastructure at higher bit-rates over relatively short (in home) CAT5e cables...(?)

This is meant as a replacement for HDMI, it's a envisioned standard where it's goals are defined as the above quotes. It's not existing yet as far as I know, but it's meant to be easier and cheaper that for instance HDMI. It's set to compete with the wireless HD standard.

[Carlo]

Still doesn't answer my question: How will they manage to transport uncompressed full HD (and more) over a CAT5e cable?
(Good thing that this discussion is off-topic!)

[Rene]

Uncompressed full HD will not be transported over IP, but native HDMI! SO this is a point to point connection, at least for the HDMI signal.

[Carlo]

Rene, perhaps you didn't read the complete article:

"As the demand for high-quality HD content distribution in the entire home is already
huge, we are hoping that HDBaseT will play the trigger role in advancing this market,
since HDBaseT enables simultaneous multi-room distribution of uncompressed HD
Multimedia as well as data, control and power over a single CAT5e cable," said
ByungJin Kim, research fellow, LG Electronics.

I was not talking about IP, but the physical CAT5e cable.
With my experience in the broadcast technology I can assure that it is not possible to transport at least 3Gb/s (needed for uncompressed HD) over a single CAT5e cable.
So there rises my question, pure out of curiosity: what kind of innovative technology will make this possible?

[Rene]

OK, I apologise.

[Carlo]

Rene, no need to apologise, I guess we're both interested in this kind of technology.
But do you think their intention will be possible? At this moment I have my doubts about the probabilities of their plans.

[Rene]

I don't know whether it is technically possible. I am not that deep into HDMI. However, the site mentions some serious corporates supporting the program.

[Carlo]

Interesting enough to follow the News updates about this article.
And who knows, we can replace our expensive HDMI/Optical/Audio/Coax spaghetti by a few cheap CAT5e cables some day...

[Post-IT]

Some article comes to mind where there has been tests between cheap and expensive HDMI cables. Under a certain length, quality did not noticeably drop or differ between cheap or expensive HDMI cables.

Maybe it's based on that principle, but then I would be interested to see how they would transfer this over longer (regular CAT5e) cables.

Here's a link to a website I used have a look at quite regularly being a good source of A/V information:

a little update (italian) with an image from engadget, but i didn't find the original article.
