The HDMI 1.4 specification will offer the following enhanced functionalities:

* HDMI Ethernet Channel

The HDMI 1.4 specification will add a data channel to the HDMI cable and will enable high-speed bi-directional communication. Connected devices that include this feature will be able to send and receive data via 100 Mb/sec Ethernet, making them instantly ready for any IP-based application.

The HDMI Ethernet Channel will allow an Internet-enabled HDMI device to share its Internet connection with other HDMI devices without the need for a separate Ethernet cable. The new feature will also provide the connection platform to allow HDMI-enabled devices to share content between devices.

* Audio Return Channel

The new specification will add an Audio Return Channel that will reduce the number of cables required to deliver audio upstream for processing and playback. In cases where HDTVs are directly receiving audio and video content, this new Audio Return Channel allows the HDTV to send the audio stream to the A/V receiver over the HDMI cable, eliminating the need for an extra cable.

* 3D Over HDMI

The 1.4 version of the specification will define common 3D formats and resolutions for HDMI-enabled devices. The specification will standardize the input/output portion of the home 3D system and will specify up to dual-stream 1080p resolution.

* 4K x 2K Resolution Support

The new specification will enable HDMI devices to support high-definition (HD) resolutions four times beyond the resolution of 1080p. Support for 4K x 2K will allow the HDMI interface to transmit content at the same resolution as many digital theaters. Formats supported include:

* 3840x2160 24Hz/25Hz/30Hz
* 4096x2160 24Hz

* Expanded Support For Color Spaces

HDMI technology now supports color spaces designed specifically for digital still cameras. By supporting sYCC601, Adobe RGB and AdobeYCC601, HDMI-enabled display devices will be capable of reproducing more accurate life-like colors when connected to a digital still camera.

* Micro HDMI Connector

The Micro HDMI Connector is a significantly smaller 19-pin connector that supports up to 1080p resolutions for portable devices. This new connector is approximately 50% smaller than the size of the existing HDMI Mini Connector.

* Automotive Connection System

The Automotive Connection System is a cabling specification designed to be used as the basis for in-vehicle HD content distribution. The HDMI 1.4 specification will provide a solution designed to meet the rigors and environmental issues commonly found in automobiles, such as heat, vibration and noise. Using the Automotive Connection System, automobile manufactures will now have a viable solution for distributing HD content within the car.

Consumers will have a choice of the following HDMI cables:

* Standard HDMI Cable – supports data rates up to 1080i/60;
* High Speed HDMI Cable – supports data rates beyond 1080p, including Deep Color and all 3D formats of the new 1.4 specification;
* Standard HDMI Cable with Ethernet – includes Ethernet connectivity;
* High Speed HDMI Cable with Ethernet – includes Ethernet connectivity;
* Automotive HDMI Cable – allows the connection of external HDMI-enabled devices to an in-vehicle HDMI device.

It says the official spec will be ready by June 30th. What, 6 months after that we'll see new devices?

NICE....
i mean please don't get me wrong, i really like innovation, BUT... Blu Ray is still on the Rise, an already a new standard is introduced??

What does 1.4 mean for us consumers, will there be Blu Ray Movies in ULTRA-HD Resolution?

i guess i'm a little nervous, just bought a new Denon Reciever and Pioneer Plasma, back in Dec., so all this Hardware will be outdated by 2010 ???

I didn't see anything indicating that they are doing anything regarding closed captioning. I know that there were a lot of folks online, who, like us, are wholly dependent on closed captioning, but these folks were burying their heads in the sand regarding digital captions, perhaps even expecting HDMI to provide some follow-up to their complaints. Unless I've missed something, it is now even clearer that the standards group does not recognize the validity of their concerns, and will go forward with their original policy on closed captioning (that decoding is to take place at the tuner or play-back devices, not at the display).

My wife and, of course, are not affected by this, because we acknowledge the reality, and took steps to ensure our equipment (tuners and play-back devices) supported what they needed to support. I suspect, though, that a lot of folks were misled by vocal zealots, and are now surprised that reality isn't conforming itself to the unfounded expectations those zealots fostered. It is a shame that folks refused to hear the truth when it was offered to them, and instead continued to delude themselves and mislead others. :sad:

Is there a reason why HDMI 1.4 couldn't send the compressed video to the TV instead of the source having to uncompress it and send the uncompressed video via HDMI to the TV?

If HDMI 1.4 could send the original compressed video to the TV, you could send a lot more in the same bandwidth. eg. higher resolutions, at higher FPS, more colour depths, more video streams (eg. for 3D, PiP).

There was an early attempt at a lower bandwidth approach using firewire. However hollywood didn't want an interconnect that was easy to copy the stream from. So hdmi was created. It was an extension of the existing DVI standard.

If hdmi had used an optical connection, the whole cable portion of the standard would have been finalized a long time ago. The TV, source equipment could change as much as their hearts desire without affecting the existing cabling! The whole thing seems to have evolved into an excuse to try to get people to upgrade their cables and equipment. Also without a new source of higher def video the new standard is largely irrelevant.

It is true that content owners disliked compressed video connections since if the copy protection was broken consumers could copy the compressed video stream. There are though two others reasons why Firewire never took off. The first reason is that a compressed video connection can't overlay graphics without using an interactive standard. The problem is that when Firewire was made the CE industry was stuck with the interactive standard that was made for it and that quickly became outdated. The second reason is that Firewire only worked with compressed video so uncompressed video either wouldn't work with it or would have to be compressed in real time. Of course HDMI could have been designed so that it could carry both compressed and uncompressed video but as noted the content owners would have disliked that.

Fiber optic connections for video would be incredibly expensive both in terms of the fiber optic converters and the fiber optic cable. It costs less than $2 per port for a 1080p60 HDMI chip and you can buy 3 meter 1080p60 capable HDMI cables for less than $5 each. For example with 5 connections (4 to the AV receiver and 1 to the HDTV) it would cost less than $50 in terms of component cost while with fiber optic that would currently cost over a thousand dollars. The current price of a fiber optic connection is so great that it doesn't make sense to use it is as the standard connector for a consumer video connection standard. In the future that could change but back when HDMI was made and even today it would not make sense to design a consumer video connection standard that is based solely on fiber optic.

Where are you getting your cable from Richard? I can find fiber MUCH cheaper than a few grand for 6 lines.

Note that I said a thousand dollars, that it was 5 connections, and that when I said fiber optic connection I was referring to both the fiber optic converters and the fiber optic cable.

I've got not clue about the converters. Are they really that expensive? Are they much different from a network optical connector?

The last I checked the cheapest 1080p60 capable HDMI to fiber optic to HDMI system was around $300.

OH! Yes, those are expensive. But an optical port can't be anywhere near that expensive. Weren't we talking about native fiber?

I have seen the price for HDMI ports but I don't know what a fiber optic port would cost which would be capable of 4 Gbps. I did a quick Google search and for a single 10 Gbps fiber optic Ethernet adaptor the lowest price I could find was about $1700. As such when it comes to high bandwidth fiber optic ports it looks to me like they are very expensive which would explain why even the latest consumer connection standards (such as DisplayPort, SATA 6 Gbps, and USB 3.0) use copper cable.

down with HDMI!

It would seem M$ at least partially agrees with me. Instead of boring old copper with a crappy connection, here we see they want to move to optical and 10Gb/s (scaling to 100). Hopefully no HDCP and then we're gold!

Ethernet channel is one of the new requirements for the spec of HDMI 1.4. Basically it allows internet connection as well as A/V signal to pass on the single HDMI cable. Before if you had separate devices that all needed internet/intranet connection (internet TV, Cable Box, Satellite Box, Apple TV, etc.,) you would have to wire all of those devices with a separate Ethernet cable to a router. Now with 1.4 HDMI with Ethernet, all the devices can share the internet/intranet signal from only one source connected with an Ethernet cable. The other devices get the internet/intranet signal through the connected 1.4 HDMI cable with Ethernet.
