I have a Blu-Ray Backup in an MKV Container that contains a DTS ES Matrix 6.1 Audio Track.
With bitstreaming enabled in MC my processor correctly displays 'DTS ES Matrix 3/3.1' and the 'back' channel is played, with bitstreaming disabled MC sends only 6 Channels of PCM over HDMI (5.1), ?
-
Set DSP Studio > Channels to the number of speakers in your setup. Leave JRSS up/down mixing enabled.

Matt thanks for your reply, why does JRSS need to be enabled for MC to detect the matrixed channel and send it to the back pair?

You want to convert from 6.1 to 5.1. That's what JRSS does.
-
No I dont, I simply want MC to send the matrixed back channel ( in 6.1 or 7.1 format) which it currently isnt doing.

How many speakers do you have?
Is it possible the file has two audio tracks, and the 5.1 one is being picked with bitstreaming off?
-
7.1 and there is only one Audio track in the mkv container.
After a little testing I have noticed that MC picks up the 'back' channels from DTS-ES but not DTS-ES-Matrix so it would seem that the matrixed channels are not being detected?

You can look at Audio Path while playing to see what format data is being input.
DTS-ES-Matrix probably doesn't get decoded as discrete channels (since they're not really).

Indeed, such is the nature of the format

Thanks Matt, I had already checked this and it shows the source material as 6 channels only, hence my original question.
So for anyone else reading this with the same issue, to date JRiver can not decode DTS-ES-Matrix, but it will happily Bitstream it.
The obvious solution here would be to just bitstream and have my processor decode the format, but this leads me to another issue...
My Processor can only decode standard DD & DTS and not Dolby TrueHD & DTS-HD-MA (although it can accept HD LPCM over HDMI) but seeing as the bitstreaming options for MC are somewhat limited either way I have to accept a compromise:
either send everything as LPCM and do without the back channels in Standard matrixed formats OR bitstream everything and only get the 'core' of
Dolby True HD/DTS-HD-MA.
JRiver could, of course, expand the bitstreaming options (as I have requested on the MC18 thread) and give users the option to choose what they want, I guess it would look something like this and my mock-up of the required options will probably make more sense than me trying to explain it:

My preference would be to support decoding of DTS-ES-Matrix on the computer side. How common is this format? Is there information about how to decode the matrixed channel?
I'll send this thread to nevcairiel (genius author of LAV Audio Decoder) to see what he thinks.
-
I only have 3 titles with DTS-ES-Matrix in my collection so didn't think it was very common however, a list of titles I found Here (http://www.hometheaterforum.com/t/17262/dd-ex-dts-es-encoded-movies-listing) is quite extensive.
According to Wikipedia (http://en.wikipedia.org/wiki/DTS_(sound_system)#DTS-ES) the track should have a flag to indicate that matrixed channels are present, let me know if you need a sample.
-
Bump ;D
Any news on this?
-
A sample would be useful.
-
PM Sent, thanks :)
-
Any progress on this? was the sample sufficient 8)
cheers

BUMP ;D

Going by the lack of response on this Topic, I am guessing that this is either not possible or extremely difficult to implement, if this is the case could we please have the option to bitstream these formats with the matrixed channels or at least the option to bitstream DD & DTS independantly of their HD counterparts as previously discussed.
