HDMI devices are manufactured to adhere to various versions of the specification, where each version is given a number such as 1.0, 1.2, or 1.3a.[12] Each subsequent version of the specification uses the same kind of cable but increases the bandwidth and/or capabilities of what can be transmitted over the cable.[12] A product listed as having an HDMI version does not necessarily mean that it will have all of the features that are listed for that version since some HDMI features are optional such as Deep Color and xvYCC (which is branded by Sony as "x.v.Color").[74][75]
[edit] HDMI 1.0
Released December 9, 2002.[12]
- A single cable digital audio/video connector interface with a maximum TMDS bandwidth of 4.9 Gbit/s. Supports up to 3.96 Gbit/s of video bandwidth (1080p60 Hz or UXGA) and 8 channel LPCM/192 kHz/24-bit audio.
[edit] HDMI 1.1
- Added support for DVD Audio.
[edit] HDMI 1.2
- Added support for One Bit Audio, used on Super Audio CDs, up to 8 channels.
- Availability of HDMI Type A connector for PC sources.
- Ability for PC sources to use native sRGB color-space while retaining the option to support the YCbCr color space.
- Requirement for HDMI 1.2 and later displays to support low-voltage sources.
[edit] HDMI 1.2a
Released December 14, 2005.[12]

[edit] HDMI 1.3
Released June 22, 2006.[12][13][76]

- Optionally supports output of Dolby TrueHD and DTS-HD Master Audio streams for external decoding by AV receivers.[77] TrueHD and DTS-HD are lossless audio codec formats used on Blu-ray Discs and HD DVDs. If the disc player can decode these streams into uncompressed audio, then HDMI 1.3 is not necessary, as all versions of HDMI can transport uncompressed audio.

I sometimes go to Yahoo! Answers because some of the questions are funny and some of them I can answer.
I tried to answer this one. http://answers.yahoo.com/question/index;_ylt=Aq5Qpo.Bm0S69XDUej8AINnty6IX;_ylv=3?qid=20080717125021AAKOefW&show=7#profile-info-J2T893XZaa
The winning answer sounded like a load of crap to me except for a few points…
But it was too late for me to make a comment.
I tried to steer the guy to the GFL group but I guess he just wanted to hear what he wanted to hear…
What do you guys think?
And how does the HDMI version improve color? I thought it would just improve bandwidth…
And I wanted to post a question to the winner to name a single game written in Blu-Ray so far…
