One player says 1509 kbps, another more like the double. My second player can’t display the exact bitrate but it would make sense if it is 3018 kbps since it’s a 24/96 DTS mix. I suspect my first player downsamples the DTS to a lower resolution to obtain the 1509 kbps or else the compression rate of the DTS mix would have to be far more than 1:4.Does anyone know the exact bitrate of the 24/96 DTS?
Follow Ups:
It's around 1.5Mb/s (or about 1500kb/s) -- not 3Mb/s (3000kb/s). It is the same bitrate as full bitrate 5.1 DTS. When the DTS 24/96 recording is made, it's encoded so that non-DTS 24/96 capable decoders can handle the signal. What a regular DTS decoder sees is around 1200kb/s (1.2Mb/s). The part of the DTS stream that the regular decoder can't see is a bit more than 300kb/s. It's in this part of the stream that a DTS 24/96 capable decoder gets the information from 24kHz to 48kHz. The regular decoder only sees the information up to 24kHz. Unfortunately, this (by "this", I mean the lower than 1.5Mb/s bitrate for non-DTS 24/96 decoders -- about 1.2Mb/s) is an aspect of DTS 24/96 that is necessary for decoding compatibility with regular DTS decoders.
I think the difference between the bitrates displayed by my two players is that one show the bitrate of the digital output while the other shows the internal bitrate (as they are read from the disc). When I put on a DVD-A with a non-24/96 DTS it shows a bitrate at 1 Mbps (it could be 1.5 since it can only display integer bitrates from 1 – 10). When I put on the Queen DTS it raises to 3 Mbps.So if this is true and one was to output a 24/96 DTS stream, I don’t see how the bitrate could be anything but 3 Mbps?
If the DTS bitrate were 3Mb/s, that would exceed the DVD-Video standard and be unplayable (I'm fairly sure the blocks would exceed the disc sector size). Remember that the DTS 96/24 track is on the DVD-Video portion of the disc, so has to adhere to those specs.Maybe your player is reporting the total MPEG mux bitrate, which could include video content and another audio track, or maybe it's just confused by the new DTS system.
What does it report when you play a DVD-Video movie with DTS sound?
Anyway, the DTS 96/24 data rate is exactly the same as that of regular DTS as described earlier in this thread.
“Maybe your player is reporting the total MPEG mux bitrate”I think your’e right about that. I noticed that when playing the PCM and DTS mix, the bitrate bar was divided into two colors while the MLP mix showed only one color. They probably indicate audio and video bitrates. Here’s what I observed:
Queen DVD-A
5.1 24/96 MLP: audio peaks at 8 Mbps
5.1 24/96 DTS: audio constant at 2 Mbps (probably 1.5 rounded), video constant at 2 Mbps
2.0 24/96 PCM: audio peaks at 5 Mbps, video constant at 2 MbpsTitan A.E. DVD-Video
5.1 ? DTS: audio constant at 1 Mbps, video peaks at 7 Mbps
