hdmi 1.3-advise please

[slowlane]

Is the hdmi on the 622 or 211 1.3 or are they 1.1? I ordered my speakers for my home theater system, and I was going with the Denon 2807 receiver. But i learned the Denon and other mfgs. will offer in 2007 receivers with 1.3, but if the 622/211 is 1.1 and not 1.3 does it make a difference---confusing????

Well HDMI 1.3 is still very new I know the Sony Bravia KD-70XBR3 supports the new HDMI 1.3 cable connection which some industry officials believe will improve both the picture and sound. The 70inch is Sony bigest TV so far but your looking at some serious money too. Which most folks will have the older version which is fine. Most newer sets will start using the new standard but to answer your question. Link below will give you all the info you want.

Just some more info on HDMI 1.3

With the launch of HDMI version 1.3, HDMI continues to increase its overall functionality to meet the needs of the High-Definition marketplace.

HDMI 1.3 will include the following new features:

Higher speed: HDMI 1.3 increases its single-link bandwidth from 165MHz (4.95 gigabits per second) to 340 MHz (10.2 Gbps) to support the demands of future high definition display devices, such as higher resolutions, Deep Color™ and high frame rates. In addition, built into the HDMI 1.3 specification is the technical foundation that will let future versions of HDMI reach significantly higher speeds.

Deep Color™: HDMI 1.3 supports 30-bit, 36-bit and 48-bit (RGB or YCbCr) color depths, up from the 24-bit depths in previous versions of the HDMI specification.

Lets HDTVs and other displays go from million of colors to billions of colors.
Eliminates on-screen color banding, for smooth tonal transitions and subtle gradations between colors.

Enables increased contrast ratio
Can represent many times more shades of gray between black and white
At 30-bit pixel depth, a four times improvement would be the minimum, and the typical improvement would be eight times or more.
Broader color space: HDMI 1.3 removes all limits on color selection

Next-generation “xvYCC” color space supports 1.8 times as many colors as existing HDTV signals
Lets HDTVs display colors more accurately
Enables displays with natural, vivid colors

New mini connector: With small portable devices such as HD camcorders and still cameras demanding seamless connectivity to HDTVs, HDMI 1.3 offers a new, smaller form factor connector option.

Lip Sync: Because consumer electronics devices are using increasingly complex digital signal processing to enhance the clarity and detail of the content, synchronization of video and audio in user devices has become a greater challenge and could potentially require complex end-user adjustments. HDMI 1.3 incorporates an automatic video/audio synching capability that allows devices to perform this synchronization automatically with total accuracy.

New lossless audio formats: In addition to HDMI’s current ability to support high-bandwidth uncompressed digital audio and all currently-available compressed formats (such as Dolby Digital and DTS), HDMI 1.3 adds additional support for new, lossless compressed digital audio formats Dolby TrueHD and DTS-HD.

Q. What functionality was added to each specification?

The following provides an overview of major functionality added to each version of HDMI

HDMI 1.1

Support for DVD Audio


HDMI 1.2


Adds features and capabilities that increase HDMI's appeal for use in both the CE and PC industries. Specifically, the features and modifications for HDMI 1.2 include:
• Support for One Bit Audio format, such as SuperAudio CD's DSD (Direct Stream Digital)
o Changes to offer better support for current and future PCs with HDMI outputs, including:
• Availability of the widely-used HDMI Type A connector for PC sources and displays with full support for PC video formats
• Ability for PC sources to use their native RGB color-space while retaining the option to support the YCbCr CE color space
• Requirement for HDMI 1.2 and later displays to support future low-voltage (i.e., AC-coupled) sources, such as those based on PCI Express I/O
technology


HDMI 1.2a


Consumer Electronic Control (CEC) features and command sets and CEC compliance tests are now fully specified.

Creation of version 1.2a of the HDMI Compliance Test Specification (CTS), which includes a CEC Supplement. HDMI CTS 1.2a has been updated for technical consistency with HDMI Specification 1.2a as well as to the recently released HDMI Specification 1.2. o Significantly, CTS 1.2a contains additional cable and connector testing and Authorized Testing Center (ATC) submission requirements. Specifically, under CTS 1.2a, the Adopter shall submit for testing to the ATC any new HDMI cable whose length exceeds previously tested cables.

Additionally, HDMI Licensing, LLC will maintain a list of approved connectors. For a device to pass CTS 1.2a testing at an ATC, all connectors on such device must appear on the approved connector list. To add a connector to this list, the vendor must submit to the ATC or HDMI Licensing, LLC full and passing testing results.

Thanks for all the info, still a little confused about the 622/211, are they 1.3?

No they are not. Very few HDMI 1.3 devices (send or receive) are out there.

 

[slowlane]

So since my TV has hdmi 1.1, the 622/211 has 1.1; I guess there is basically no reason to wait and purchase a a/v receiver with 1.3. I was hoping after reading the 1.3 info, I thought maybe connecting the 622 hdmi to a 1.3 a/v receiver, then to my TV hdmi, the 1.3 receiver would synchronize the video and audio and eliminate lip sync problem?

 

[StevenZ]

Bear in mind that every new revision of the HDMI spec adds only the potential for new features. HDMI 1.3, for example, does not require any manufacturer to implement those features. In particular, the only one Poke listed that would have much benefit to Dish subscribers is Lip Sync. Support for Deep Color, xvYCC Color, and more audio codecs won't make any difference on a Set Top Box that sends along NTSC & ATSC video which don't support those features.

Bottom line, don't look for which HDMI version is in a box. Look for the set of features the box has implemented.

There is no source available with 10bit color nor is there likely to be for many years. Because of bandwidth limitations is is highly unlikely that satellite would ever carry 10bit color even if it becomes available on the next consumer HD product after HD-DVD/BD. This would likely be 10 years or more anyway.

So no the 622 doesn't have HDMI 1.3 nor would it be needed on any of it's successors.

 

[StevenZ]

I think you missed my point. I agree that 10-bit color isn't a feature of HDMI 1.3 that we should be anxiously awaiting. But the lip-sync feature of 1.3 would offer some benefit.

The problem is that a box that claims "HDMI 1.3" doesn't give us a clue as to whether the box has implemented 10-bit color, lip-sync, both, or neither.

Blu-ray and HD DVD do not support 10bit color.

Blu-ray and HD DVD do not support 10bit color.

Did you read my post? I said on the NEXT consumer format AFTER HD-DVD/BD. Meaning that HD-DVD/BD only support 8bit color.
