I read that i can use HDMI 1.1/1.2 to transfer DTS-HD & DD+

If this is the case, what would be the advantage of 1.3 over 1.1/1.2 in relation to DTS-HD & DD+ ? :confused:

Interesting. 1.3 would be an advantage in video quality if your HDTV in the future supports it. For current audio it seems not to be an issue with those setups if your BD player has a decoder like the PS3 does.

If the decoding of the HD audio formats is to be done in the AVR, then you need HDMI 1.3 to transport the audio from the player to the AVR. If the decoding is done in the player, then you need HDMI 1.1 or 1.2 to transport the decoded PCM audio to the AVR (or a bunch of analog cables). It is preferable that you decode in the player because you will lose some functionality of the disc if you do it in the receiver. The player must mix together disparate audio content (menus, commentaries, other extras and stuff) with the main soundtrack before sending that information out. If the decoding is done in the AVR (with Dolby TrueHD and DTS-HD MA decoding capability) then you won't get all that additional stuff transported to the AVR with the way virtually all HD DVD and BD discs are mastered.

The latest lossless surround sound formats (Dolby TrueHD and DTS-HD Master Audio) can not be transmitted on the traditional SPDIF (also called IEC-958) digital audio interfaces due to the very high data rates of these new formats that exceed the capabilities of SPDIF. SPDIF has a 6.1Mbps maximum data rate, while DTS-HD Master Audio, for example, can require up to 24Mbps.

The HDMI spec, since the first 1.0 version, enabled up to 8 channels of 192kHz PCM audio to be supported, which means that decoded Dolby TrueHD and DTS-HD Master Audio can be handled. In fact, most (if not all) of the HD-DVD and BluRay players have the ability to decode these formats and transport them as multi-channel PCM on HDMI. This is great, because quite a few HDMI AV receivers can receive multi-channel PCM on their HDMI inputs, and thus render them on the speakers.

HDMI 1.3 adds the ability to transmit encoded DolbyTrueHD and DTS-HD Master Audio on HDMI. This adds another level of flexibility to choose where the audio is decoded (by the source, or by the AV receiver for example). But as mentioned before, HDMI 1.3 is not required to enjoy these new lossless audio formats since devices can perform the decoding in the source and then transmit the audio as decoded PCM instead.
