Regardless of what the spec's say, real life is somewhat different.
I had a HDMI 1.1 receiver and it would not pass through audio. Called tech support and they confirmed you can't pass through 5.1 digital audio in that version. Just like it wouldn't pass through 1080p. As well as my HDMI compliant Motorola cable box cannot pass through 5.1 digital audio and it's HDMI 1.1.
I just have an HDMI going directly from my video sources to the TV. And then I have optical cables going from the sources to the receiver. I don't have a Blu-Ray player, so lossless digital audio is not applicable in my case.
HDMI 1.2 won't pass 5.1 in most cases. That's why places like avsforums and audioholic forums are full of threads of people complaining about how their HDMI doesn't pass through audio in older firmware versions.
that's beause of your devices firmware, not the limit of HDMI
Q. Do you need a new version of HDMI to play Blu-ray and HD-DVD content in high definition?
All versions of the HDMI specification support the ability to watch HD-DVD / Blu-ray content in high definition up to 1080p resolution. However, there may be non-HDMI reasons that prevent some devices from accessing content in high definition, including lack of HDCP support.
Q. Are HDMI 1.0, 1.1 and 1.2 compatible with the next generation videogame consoles implementing 1080p and HDMI’s new Deep Color capability?
The HDMI specification has supported 1080p content since version 1.0, and each new revision of the HDMI specification is fully backward compatible with previous revisions.
Q. What functionality was added to each version of HDMI?
The following provides an overview of major functionality added to each version of HDMI:
* Support for DVD Audio.
* 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), 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.
* 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.
* 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.
* Higher speed: HDMI 1.3 increases its single-link bandwidth to 340 MHz (10.2 Gbps) to support the demands of future HD 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 10-bit, 12-bit and 16-bit (RGB or YCbCr) color depths, up from the 8-bit depths in previous versions of the HDMI specification, for stunning rendering of over one billion colors in unprecedented detail.
* Broader color space: HDMI 1.3 adds support for “x.v.Color™” (which is the consumer name describing the IEC 61966-2-4 xvYCC color standard), which removes current color space limitations and enables the display of any color viewable by the human eye.
* 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 automatic audio synching capabilities that allows devices to perform this synchronization automatically with total accuracy.
* New HD 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 Master Audio™.
that about sums it up. Experience my ass.
