list of MPEG2 multichannel audio svcd capable players?

[slugbug]

anyone have a list of MPEG2 multichannel audio svcd capable dvd players?

[orbit-r]

hi slugbug;
as far as iknow doom9 was figuring out (some time ago)that only phillips player will play mpeg multichannel...

for a list of svcd compatible svcd player go to...www.vcdhelp.com

That list of dvd players at www.vcdhelp.com does not show their compatability with MPEG 5.1 decoding...when using a cdr made with DVD2SVCD..

Any other help?

This is new thing that DVD2SVCD just started to offer. I dont think that there are any other programs that will let you make a SVCD with 5.1 sound. So I dont think that you are going to be able to find a list of DVD players that support this.

[Doom9]

perform a search in the audio forum.. there's a long thread about this.. I think one or two Philips players can handle the format but that's it.. so your chances are pretty low.. I think even your chances of getting miniDVD to work on your standalone are better...

[dvd2svcd]

Actually I have reports that pioneer supports it too (or was it panasonic).

[Sofliberty]

(I think)I can confirm Pioneer. Have Pioneer dv-343 and it works with SVCDs encoded with 5.1. Dont know how to tell if its "true" 5.1 but the it sounds like 5 separate channels. (use w/ pioneer VSX-D510 reciver). have to encode w/ audio bitrate of 384 2 avoid high pitch distortion but its well worth it :)
Tnx dvd2svcd...

@Sofliberty:

Would you mind try using VCDXBuild to make you CD Images, I'd like to know if Multichannel works with VCDXBuild too.

[Sofliberty]

Did a few chapters of "Matrix", using VCDXbuild.
Works just fine.

How do i know if its "real" 5.1 or just "bad" ears on my head?
Suggestions for a movie where its easy to hear the difference are gratfully accepted.

Seems to me that the sound is a bit "flatter" on the SVCD than on the DVD, setting to B done somewere?

[myMars]

if you have a dolby decoder, it will show you the type of dvd player output.
on a sony device (a friend has one) for a regullar mpeg1 layer II svcd disk it shows pcm 2 channels.

Star Wars Episode One have a test sample that make sound in one channel at a time while showing it onscreen.

When the decoder say PCM (Pulse Coded Modulation) is NOT recieving two channels of MPEG.
PCM 2 channels meens that your DVD-player have expanded the mpeg into playable PCM. PCM is a format similar to Wave-format on PC.
The rest is correct. If you have a DVD-player that output the unaltered bitstream from the disk a standalone decoder can separate the channels.
Remember that only a fiew of standalone decoders have support for Multichannel MPEG, or MPEG at all.

I have an Apex AD110W, bought it at wally world...plays all my svcd's in Dolby 5.1, i know this because i have it routed through by Sony DAV-S300 DVD/Sound system (which i might add does not play CD-R's)
Just like being at the movies!!!
Apex rules!

Thank U. Will try that as soon as I can get my hands on a copy.
My reciver don't display any info about the media, hence the question.

Sveriges framsida....

[Sofliberty]

Did try an encode of THX.
confirmed that my player can read 5.1 audio from SVCD.
also confirm that vcdxbuild don't make 5.1.

The audio is the same so my guess is that this can be due to I-Author writhing a multichanel header for the audio, and vcvdxbuilder don't.

@ Linux:
Thanks for the help with solving my dilemma.

[hoozdapimp]

sofliberty are you sure this works? i have the 343 and I cannot get it to play 5 seperate channels...it sounds more like 2.1 or 3.1, not 5.1..and i think i remember markrb saying he didn't get it to work with the 343 either.

if so could you either contact me or post a little sample of the file you tested with so i can test it myself?

[markrb]

Yeah I did say that, but I tested it with an old version.
I couldn't get any sound at all so if you are getting something then this proves it does more then what I could do.
I did promise to try it again, but I really haven't had the time.
It will be at least another week before I do.
Mom is coming up for a few days to look at the pretty trees.
I am really interested to try it myself so be assured I definately will the moment I can.

Hmmm...I have a Pioneer 333 (which is pretty similar) and it does *not* support 5.1 SVCDs. Yours is outputting a true Dolby digital signal through a digital audio connection to your reciever?

[Sofliberty]

what i did was:

Ripped the THX sound setup from star wars episode one. ( in the extras)
Created an svcd disc of this. (using DVD2SVCD)
Played it on my pioneer.

What i got with I-Author:
Sound from: Left front,then left center and right, then right front.
What i got with vcdxbuild:
Sound from left front, left front, center and right front.
after that it restarted from left front.

conclusion: the sound is not 5.1 but it plays 5.1 sound :)

hardware: pioneer dv-343 and pioneer vsx-d510 coaxial cabel connect.

I apologize if I misled enyone with my inexpertise.

[hoozdapimp]

ok this is the same result that i get...this is just the receiver outputting sound in all speakers....which is not 5.1 sound :)

if that was the case i would be getting tv broadcast in 5.1 :)

it's ok tho, too bad our player doesn't play it

[Sofliberty]

Still confused.

Playing the same disc ( DVD2SVCD I-Author muxed 5.1)with reciver set on Dolby Prologic I get sound from speakers (in sequence) left,center,right,center then both rear surrounds.
Is it my reciver tricking me or is it actually geting more than 2 channels from tha standalone? (se above for hardware).

[markrb]

Does anyone have one of those real 5.1 test discs?
It's the one that says the name of the speaker that should be working. IE.. If it's suppose to be out of the left front a voice will say "left" and if out the left rear they will say "left rear".
I had one somewhere, but I can't for the life of me remember where and what it was from. I am almost certain it was on a regular DVD as I never bought a setup DVD.
I am so busy now I haven't even had time to try the new beta yet. If I get time I will try to hunt this disc down.

Mark

[hoozdapimp]

dolby prologic is something that your receiver can do to emulate 5.1 surround sound...usually some sort of algorithm (see the sound sectoin if you really want to know more), the receiver will take parts of the sound and send them to the rear speakers and other parts and send them to the front...if you listen closely you will see that mostly background noise (mostly never voices) are sent to the surround speakers.

[Sofliberty]

@ markrb

By suggestion from Linux:

This is the disc I'm talking about in my previous post.
Problem is that on the original disc the the speaker highlighted on screen is the one sounding until one presses "next chapter". this do not work on the copy (selected DVD chapters in D2S) but the sequence of the sound follows the sequence of the original.

@ hoozdapimp

i'ts not movie sound I'm talking about. Seems strange to me if the reciver could successfully guess to which speaker the disc is sending the audio signal.

Its good 2 C someone interested, figured this was a dead tread.:)

[/B]

So what sound are you talking about? But yes, using some not-so-simple matrix math one can manipulate 2 channel audio to give a pretty nice sounding surround sound emulation.

@markrb: I downloaded one from a thread...I will search for it again, and update if i find a link.

edit: this link (http://forum.doom9.org/showthread.php?s=&threadid=9113&highlight=mpeg+5.1) should have some test files

[Sofliberty]

The sound I'm talking about is from THX surround setup, a part of Episode one.
It shows a drawing of a room with speekers in it, one speaker is highlighted and sound comes from the corresponding speaker in the surround system. next another speaker is higlighted and so on...
In sequence :left, center, right, rear surround.

on the copy of this that i make with D2S the sound follows the same sequence.

That's the sound im talking about

[markrb]

Sofliberty if it goes to all the speakers when it's suppose to I would have to guess that it's 5.1 audio.
That was the disc I was actually talking about. I really gotta pay attention. I mean you only mentioned it like 3 times.

Man do I wish I had more time. I really want to test all of this stuff. I am getting sick to boot. 2 colds in less then 3 months. This is a record for me.


hoozdapimp thanks when I get some time I will dl'ed it. Although if it's the Dolby Digital Demo. It's been determined that it's copywritted and we must get rid of all the links to it. We have an email from Dolby Labs confirming this.

Mark

[hoozdapimp]

im not sure if the dolby digital is on there...i think something about thx is on there, and then frank made some of his own tests for us to download.

[markrb]

I just did a quick test of 5.1 Mpeg sound.
I did a chapter using both I-Author and VCDXBuild.
Both discs played in both my DVD players (Pioneer 343 and Apex 5131).
My reciever said Dolby Pro-Logic II. It uses that if the input is not AC3. So all I know for sure from the screen is that the input is not AC3.
The rear speaker output was there. Whether it was mono or stereo I could not say. Also the sound in the rear speakers was a bit distorted. I could tell no difference between the disc made with I-Author and the one made with VCDXBuild. This is good because I tend to use very high bitrates that would make I-Author fail.

This is very early in my testing. All I wanted to know with this test was if I could make a disc with DVD2SVCD with 5.1 sound selected and whether it would work using I-Author or VCDXBuild.

So those questions are answered in the positive. Now it's onto what is the sound output. Is it truly 5.1?

Mark

[Sofliberty]

On my system theres a big difference between I-A and vcdxb.

on playing the THX this is what i get:

vcdxb: center, short burst in right, left, center,left, center after that there is only left, center, alternating

I-A: left, center, right,left, center, right,rear surrounds after that it starts with different combinationes of front and rear speakers, much like the original.

I have not managed to get to "chapters" working so the picture does not correspond to the sound but seams to me sequence is about the same as on the original.

But clearly a difference I-A vs vcdxbuild.

tryed to make a Mini DVD of the VOB's but still no sucess, hence original sequence is from memory only.

[markrb]

I just tried that Star Wars THX test.
I played the actual ripped VOB and it seems to be wrong somehow.
I can't explain it, but I found that my APEX player will play the ripped VOB files directly and it's even wrong in that.
I didn't encode a thing. It's the straight AC3 file.

If I play it off the original DVD it's fine, but ripped it's wrong.

I will look into this further, but if my findings are correct then this file is not a goos choice to use as a test.

Mark

[Sofliberty]

@markrb
read. any idea on where it went wrong? tried different rippers?
other suggestions on test material?

looking at the process (I belive)the difference between I-a and vcdxb is that I-A remuxes writing a multichannel header

Given the results on THX i still belive we get at least 4 separate channels from pioneer 343 (no active sub so I don't know about .1 :()

anyways it sounds better with 5.1 so its really not all that important...

[markrb]

Having failed the THX setup I made a couple of SVCD's using the Pod Race Scene. 1 had Surround2 encoded and the other Mpeg 5.1 with VCXBuild(I only own 2 CDRW discs so I-Author will be next).
I listened closely right at all the speakers for both Discs.
I couldn't tell one bit of difference between the two.
Both had a definate center, a definate left and right and a definate rear. What I couldn't tell was whether the rears were independent or not.
More testing is in the works, but if I-Author muxing is anything like the VCDXBuild then I will stick with Surround2 in BeSweet.
