I thought it would be nice to have a forum just for the new Denon DVD-2500BTCI blu-ray player. I love the idea of just having a transport and allowing the amp to do all of the work while lowering the cost over the more well equipped DVD-3800BDCI.


UPDATE: People now have these starting here: http://www.avsforum.com/avs-vb/showt...3#post12901383


Known issues so far:

-5db LFE channel on PCM (same as Panny BD players hmmm)

Has anyone heard when this is going to be released? The Denon Article .

Do you mean the Denon DVD-3800BDCI?

No, I am interested in the model below the 3800BDCI. Here is the product info. I have the new Denon 4308 so I would be duplicating much of the hardware and software if I were to get the 3800BDCI.


DVD-2500BTCI Blu-ray Transport: High-Performance Connection to A/V Receivers

The DVD-2500BTCI is a leading edge Blu-ray Disc Transport that allows owners of advanced A/V receivers to add Blu-ray capability to their system and enjoy high definition video. The DVD-2500BTCI will natively output an HD audio bit-stream to a connected receiver via HDMI. Once this signal is accepted in the receiver, it can then be decoded into its native format including Dolby Digital Plus, Dolby TrueHD and DTS HD Master Audio.


Secondary Video and Audio Decoders

In keeping with the guidelines mandated by the Blu-ray Association for BD-ROM Profile 1 version 1.1 players, both Denon Models DVD-3800BDCI and DVD-2500BTCI incorporate a secondary audio and video decoder. This allows for simultaneous playback of a secondary audio and video track which may be used for interactive audio and commentary and for picture-in-picture capability (respectively). Additional information (subtitles, audio streams, camera angles, trailers, games, etc.) can be downloaded from the Internet via computer and stored on a SD card that either player will accept. This content can be played with the original content of Blu-ray Discs.

I'm also interested in the Denon 2500 BD transport, but I wonder how a player like this can send a compressed bitstream to an AVR for all discs. Supposedly the audio tracks on many current discs are mastered in such a way that the player is supposed to decompress and mix them before output.


Thoughts?

That was my impression as well, as currently all blu-ray discs are authored in Advanced Mode, which means the player HAS to decode it. I may be wrong but thats how i interpreted it on the insiders thread.


Im keeping the PS3 and just upgrading to a hdmi amp for pcm

I think we would all like that question answered. If it can be done and done well this player might just get the nod.

How'd you get a 4308? Mine doesn't come in until tomorrow.



There are so few THD discs that it doesn't matter, so MA is the only real issue ATM. BD is a complete cluster. It seems like it will take another year to get players, discs and receivers where they need to be. Too many cooks.

I am interested in this player also.


Now you have my interest in "adavanced mode" decoding. What is this about? Link? I haven't heard of that yet.


I was under the impression the reason the player had to do the decoding was because there wasn't a receiver/pre-pro that could decode the bitstream. Now with the onkyo/integra products coming out(which claim to decode advanced audio), we don't have a player that will pass the bitstream to test. I didn't think it was a software issue but a hardware issue.


Talk about the chicken or the egg................

The Denons will do it, but they need a player that will pass it. The XA2 might, but that's it ATM.

I was lucky enough to find a local dealer who had a few in stock so I paid TAX and have the comfort of working with a local business.

I gather that we still don't have a price for the 2500? I figured they'd announce the price for it along with the 3800 press release.

I've read in several articles that $1,199 is the asking price for the DVD-2500BTCI.


That's a bit more realistic than $1,999 for a first gen blu-ray player, but I don't know if it'll be worth the cost if in a year you can get cheaper, better models.

That does sound interesting. So does this unit have any kind of video processing? Or is it pretty much bare bones and the video upscaling is the responsibility of your Video Processor or A/V receiver?

Yes. It sounds like Denon dropped the advanced audio and video processing on this model so people will have to use their own receivers with built-in decoders and scalers. As someone who plans on owning a AVR-3808CI, this would work for me. However there's yet no infomation on what this thing will do for standard DVD's, and since I really want one deck to handle all my movies, I'll probably choose something else.

Talk about the chicken or the egg................

I did a little more research on the subject of "Advanced Authoring" and it appears to only affect HD-DVD players, not Blu-ray.


Taken from the "Why you don't need HDMI 1.3" thread:

"Some newer receivers have HDMI 1.3 along with the ability to decode DTS-HD and TrueHD. This ability is not as useful as it would seem. Firstly, there are no current players can send these as bitstreams (meaning the actual compressed signal stored on the optical disc.) Denon has announced a Blu-ray player that can do this, but no known HD DVD players can do this, and they may never. Because of a feature on HD-DVD called known as "advanced content" (menus over video, PIP, Information overlays, and the audio present in these features), players need to be able to decode the soundtrack and mix advanced content audio with it. Which is another reason players provide internal decoding. "

I am a huge Denon fan, but I can't justify $2000 for a blu-ray player. $1000 or so? Maybe. So, I m trying to figure out how this device will work.


I have a 4306 with an open hdmi input. What audio formats will my AVR support coming from the 2500CI?


Since the 4306 also does upscaling, then SD DVDs should play just fine as well, right?

Currently yes, but what happens after BD 1.1 when the new movies have this PIP etc, in which case the disc may have to be advanced authored to mix sound, what would happen? Will this player not play any AA discs if they should surface?

Actually from the profile sticky


BD-Video 1.1:


256 MB of persistent memory required

SD PiP decoding required

secondary audio decoding required

no internet capability required


This appears to be heading to advanced authored discs. Why else would they want secondary audio decoding in the player itself?

As was asked in another thread about dropping Denon link, from an AVF forum audio guru, it now looks like with the HDMI 1.3a spec, HDMI will now include Audio Rate Control.


from the post by welwynnick


Quote:
The Audio Rate Control feature allows a Sink to slightly and continuously adjust the audio clock rate of the Source in order to match the Sink's crystal-based audio clock. The Sink controls the Source's audio clock rate with the CEC command. See CEC Supplement section CEC 13.16 for details. Source ACR behavior is not affected by Audio Rate Control. When Audio Rate Control is enabled the Source shall continue to generate correct ACR packets that accurately reflect the current (possibly adjusted) audio clock rate.


Now, doesn't that sound just like adaptive rate control, and something rather like iLink over HMDI?

i think this is the best reason why no denon link.

for adavanced content AUDIO


maybe the audio gets mixed in the player via the standard and secondary audio encoders, but then outputted to bitstream, instead of going to on player truHD, DTS MA decoders etc.


so the recievers just do the end result. how would that be any different? as its the standard and seconday audio encoders that do the mixing not the truHD, DTS MA decoders
