I have a new reciever coming in less than a month to upgrade my home theather to the new Dolby Atmos standard. My question is will K be pushing thru a firmware update soon to be able to push the new 9.2 or 11.2 standard to my reciever? My new reciever will process the signal as long as it is sent bitstream in the new 9.2 standard.
 
Atmos should not require a firmware update from K. As long as you're sending bitstream from your player to an Atmos-capable receiver, the receiver should recognize the Atmos-embedded stream. Atmos is designed to be backward-compatible with players and receivers.
 
I am not sure the last post was 100% accurate. For a receiver or pre/pro to be capable of decoding this new format, that processor must be capable of implementing the new algorithms required by atoms. Only receivers or pre/pro's that specify they are ATMOS compatible will be able to implement the new format. There is a requirement of additional channels necessary to convey the new spacial information... A receiver would need additional speaker outputs. A Pre/Pro would need new line-level outs to drive additional amps...

That being said, it is true that there is no need to replace ones Blu-Ray player, and by implication a Kaleidescape system, since it more or less is a giant player. Here is a good article that details this...

Sorry Wilson,


I was reading the post on my iPhone - a bad thing to do at my age :) I saw that you mentioned "Atmos is designed to be backward-compatible with players and receivers." But looking at it on a bigger monitor, I now see you also stipulated "Atmos-capable" in another sentence...

Imported the new Transformers movie into the Cinema One (2nd Gen) and played the movie on my new Dolby Atmos receiver. Came thru loud and clear. The Dolby Atmos codec is a must upgrade for hem theater. I was unreal sounding. Do yourself a favor and upgrade your receiver to an Atmos enabled one. You won't regret it.
 
There seems to be an issue on Some Atmos material including Expendables 3 and the Atmos Demo disc. This is a confirmed issue they are working on currently.
 
What's the issue? (I'm curious:))



Jim
 
I had audio dropouts. When I called tech support they said it is a known issue.
 
Thanks guys!





Jim
 
Is the dropout issue solved? Also, what is the best way to find Atmos titles in the Store? I tried the obvious, searching for "Atmos" in the search bar, but of course that turned up nothing.
 
Bummer. I had 8-10 dropouts in one movie, most recently. Not Atmos, mind you, because I haven't gotten my ceiling speakers installed yet, and actually this wasn't an Atmos movie. I only have one player, an M300, so I don't think the system is overloaded from a streaming perspective.
 
These problems tend to be "seamless branching" issues, in particular when part of Dolby TrueHD Playback and using Bitstream as opposed to PCM (required for all KPlayers given the lack of internal HD codec decoding). Not sure firmware can fix the issue, it may require some hardware change at some point, or a modification to the BR disc encoding, not sure that's even being considered. There are a lot of BR players in the market suffering from the same problem, so hopefully a fix for all will be forthcoming, but be prepared to live with this issue for awhile.

There appears to be some change with the latest KEOS upgrade. The Expendables 3 and the Dolby Atmos disc that were not working properly seem to have been cured.
