Supposedly this is the new format that most manufacturers were waiting for. I have to say this is a surprise to me.

It's also worth noting this is the format that PS3 will adopt.

yeah... not many electronics have the spec yet but future ones will.It's pretty cool I guess if your really into audio especially.But the higher bandwidth and the other specs seem excititng too.

With the ps3 I'm wondering how much impact it will have since it will be played mostly on tvs that don't have the updated spec.Any info on that?

We discussed this in the PS3 forums. Look for my posts in these threads:

but unless you're thinking of upgrading your audio setup for Dolby Tru-HD and DTS-HD or unless you have a high-end 1080p HD display - it won't really mean that much in practical terms.

The group controlling the interface, HDMI LLC ... decided to upgrade HDMI to version 1.3, where the increased bandwidth will allow support of 1080p displays with up to 36-bit RGB color.

The new version also adds automatic synchronisation between video and audio tracks - dubbed 'lip sync support' - and extends the list of audio formats it can handle with the addition of Dolby TrueHD and DTS-HD Master Audio lossless compressed codecs.
--------------------------------------------------------------------------------

At least they made the PS3 future-proof - until version 1.4 comes
out.

Just to clarify my last post: As far as I know none of the current 1080p displays or current audio equipment have HDMI 1.3 capability since the specs just came out earlier this month. These will come out later this year. So if you really want to take advantage of HDMI 1.3 make sure you research the specs well. Current HDMI users may have to send back their equipment to upgrade to 1.3.

It will have no impact at all if your equipment does not have the 1.3 spec. However, it is backwards compatible with previous versions of HDMI. You just won't get the full benefit of 1.3's features.

The crazy thing about HDMI 1.3 is that it might not have any effect at all on the quality of picture or sound from HD-DVD or Blu-ray. Since the color space and color depth are already set in the standard(s) those things won't change. Audio options will increase but there won't be any reason to use them!

It has come to my attention that passing a raw digital audio stream to a receiver/proccessor isn't needed and is actually impossible to do with HD-DVD and Blu-ray players. Ever since these new formats have arrived people (including myself) have been treating the new hardware like the old DVD players. One of the largest arguments against the formats have been that they aren't ready because HDMI 1.3 wasn't ready. Since the discs could contain Dolby TrueHD or DTS-HD and theose new audio formats could only be passed via HDMI 1.3, without HDMI 1.3 quality would be lost right?

Wrong. Since everything is transcoded internally within the player(s) to PCM (L-PCM) there is no need to pass anything but PCM to a receiver. If anything else was to be passed then it would require another encoding job before exitting the player. Encoding again could cause some loss in audio quality. The only connections that require extra compression are the S/PDIF connections.

------

The best ways to listen to a Blu-ray or HD-DVD player(s) are...

1) 6 or 8 channel PCM over HDMI.

2) 6 or 8 Channel PCM over Analog Multi-Channel Audio connections.

3) DTS or DD via Digital Coax or Optical, over S/PDIF.

4) 2 Channel PCM (Downmixed) over Stereo audio connections.

In that order!

HDMI 1.3 is huge, but not for HD-DVD and Blu-ray,
Ced
