That means that changing the D2 to accept those for input would, at the very least, require changing out the chip set that implements the HDMI connection.
In addition, to do more than mere lip-service to HDMI V1.3 would require significant changes in the audio and video data paths throughout the D2 hardware. This would be pretty pointless right now since there's no content that could take advantage of it. Of course there are plenty of HDMI V1.3 products that do just that (lip service) in order to boast the HDMI V1.3 label, but I don't think Anthem feels the need to go that route so long as they can sell D2s faster than they can make them.
So the bottom line is that an HDMI V1.3 product would require a hardware changeout (not just new software), and would probably involve enough of a hardware changeout that it really should be a new product.
A more pressing problem for the D2 is that it can only accept 5.1 channel PCM input instead of 7.1. (The same is true for multi-channel analog audio input.) Unfortunately, that too will require a hardware changeout, and not a trivial one either. Due to the content out there now, this too is at the margins of interest, but is likely to become more interesting sooner than HDMI V1.3's fluff.
I know from previous posts, the whole HDMI v1.1 vs 1.3 has been discussed as it relates to the D2 on the audio side, and Bob, you confirmed what I thought the answer might be with regards to trying to enable 1.3 audio functionality via a potential software upgrade.
So, while on the subject of HDMI 1.1 vs 1.3 and hardware upgrades, and extending the discussion to video, is the Gennum VXP processor (now sold to Sigma) capable of being used to exploit the video functionality of HDMI v1.3? I understand the VXP is a 10-bit processor in the current 8-bit environment, while HDMI 1.3 handles 10-, 12- and 16-bit i.e. Deep Color or whatever you want to call it. I am bearing in mind that availability of material at these bitrates is a different subject altogether.
The reason for asking is as follows:
1. Marantz is using the VXP processor in a HDMI v1.3 compliant projector http://ca.marantz.com/Products/2009.asp
. So I am assuming that the VXP processor is 1.3 compliant.
2. While I understand the hardware limitations of the HDMI v1.1 vs 1.3 on the audio side, if Anthem were to design a 1.3 compliant D2, could it use the existing VXP processor thereby potentially offering the 1.3 conversion as an upgrade to existing D2 owners? My logic being is that the VXP processor (a major selling point, and one of the reasons I bought the D2) is already 1.3 compliant/capable if 1. above is valid. Hence from a marketing perspective, Anthem could offer the 1.3 upgrade at a lower price than buying a whole new D2. Maybe this falls in to the wishful thing dept?
I am comfortable with the 1.1 vs 1.3 debate as it pertains to the D2, so this is more about setting expectations and planning for the future a few years hence.
