5.1 dolby digital and DTS system via optical - BD-UP5000 or BH200?

post #1 of 23
Thread Starter 
Guys - I'm wondering which player will be better for my 5.1 system that does dolby digital and DTS, via optical cable. I think I've read that both of these players can convert all audio for blu-ray and hd dvd movies to DTS for these type of sound systems? Is this true?

True HD (on the Dolby side) and DTS HD-MA (on the DTS) side are high-end audio codecs showing up more and more on Blu-Ray discs. But at their "core", you will find the tried-and-true Dolby digital 5.1 and DTS 5.1. True HD and DTS HD-MA are "wrapped around" this core. Either player will dig down to the "core" audio and send it out via bitstream (through its optical or coax connector) to your 5.1 receiver. Your current receiver can't decode the "outer wrapper" of these formats, but since it has DD 5.1 and DTS 5.1, it will decode the the basic 5.1 "core" of either audio format. In short, either player will do the job for you.

The BH200 has a feature called DTS Re-Code, which takes all the lossless formats and converts them to full bitrate DTS, which I think is 1.5Mbps. In most cases, this will give you the best sound over optical. I don't know if the Sammy has a feature like that.

The BG200's DTS Re-code feature does NOT, however, take a lossless DTS stream and convert it to Dolby Digital. In other words, if you have a DTS-only Blu-Ray disc (i.e. - "Hairspray"),the player will not convert it to a Dolby Digital 5.1 signal. It will convert it to two-channel stereo, but that's all you'll get if you have a Dolby Digital-only receiver.

The BH200 (perhaps only with newer firmware than november/january) does convert every audio-track (incl. DD+, DTrueHD, DTS HR and DTS HD Masteraudio) into a DTS-Bitstream with 1.5 Mbps and a max. of 5.1 channels (via SPIDF/optical and set to DTS Re-Encode).

I've hooked up mine with HDMI, but last week I tested the Re-Encode with an optical cable. So, It really works with up to 5.1 channels for every audio-codec. I think this was the question of sl@acker.

Dolby True HD does not have a "Core" of DD, only DTS HD has a "core" of DTS. I believe that the UP5000 (and possibly the LG) WILL reencode the Lossless formats to DTS @ 1.5 mbs. Which should be better than regular DD.

Really the re encode only effects the Dolby THD and DD+ soundtracks, because DTS HD (both HR and MA), have the DTS core all ready. So as long as your receiver can decode DTS, that would be your best solution.


I think most movies that only list a Dolby THD track, still have a "hidden" DD track, but it is not part of the THD track. Which in any case would be better to re encode the THD track to DTS.

Both convert all formats to 1.5Mbps DTS. There's no difference in this respect.

My HDMI AVR is only capable of decoding upto DD+ & can accept PCM but doesn't bitstream process the DTHD or DTS-MA.
Currently, I set my BH200 to Mutichannel PCM resulting in my AVR showing it as PCM.

On my old Tosh A30, it used to show DD+ which tells me the AVR was decoding the DD+.

Now I am not sure with the BH200 - even though PCM doesn't sound perceptibly any different than the original source audio from what I've read.

Should I set my BH200 to some other setting to let the AVR actually do the DD+ decoding?
I wonder if

Your Tosh A30 can't bitstream DD+, it can only decode it to PCM. An A35? Yes. However, an A30 can only decode high res audio formats. An A30 can bitstream DD and DTS.

Personally I think the player should do any and all decoding and re-mixing, but many people's AVR's will only perform processing on decoding audio rather than PCM. So they prefer that.

What AVR are you using, I've never heard of one that can decode DD+ but not Dolby THD. I wonder if you are actually bitstreaming DD EX.

Sony DG810.
Sorry I should have just said DD not DD+.
Maybe that's the problem. I might have only seen DD on the AVR not DD+.

Thanks for the responses guys. Just to confirm, this is the definitive answer? Both players decode all HD audio formats to 1.5mbps DTS?

Last year's DG810 can't decode the new high res audio formats. This year's DG820 can. The A30 recodes Dolby TrueHD and DD+ to DD over optical whereas the A2 recodes DolbyTrueHD and DD+ to DTS.

I'm talking only about the players in my original question - The LG BH200 and Sammy BD-UP5000

Thanks allargon. I think the OP wants his thread back.

The LG can convert all audio formats to 1.5 Mbps DTS for sure (up to 5.1 channels).

The sammy I don't know. But usually bradavan knows of what he speaks
So, it seems that both will handle it.

It's been discussed many times before, but I'll add to this statement that re-encoding isn't always the best option (I would actually never consider it the best option).

With the BH200, the DTS Re-Encode is the most convenient option (instead of changing settings all the time), but I will caveat that by saying I've noticed some clipping (popping) on some DD+ tracks re-encoded to DTS. The Clipping isn't present when using DD.

I haven't noticed any clipping on THD tracks re-encoded to DTS yet. I'm happy about this because the only way to get 5.1 from THD over optical is to re-encode to DTS (pass-through will give you stereo DD).

The 2 combos are now identical in the sound capabilities as far as I can tell...
post #19 of 23
Both are exactly same as Vinnie97 and Bradvon said.

Re-encode is the best option if your AVR only has SPDIF connection, no HDMI audio at all.

If your AVR has HDMI audio but only HDMI 1.1, use PCM is the best option.

Sammy 5k also has 7.1 analog out to offer you a 3rd option of connecting hi-def audio to old AVRs that doesn't have HDMI at all. It offeres same ouput as HDMI PCM mode with a rudimental bass management implementation.

I have the BD-UP5000 connected to a Denon AVR-3300 via co-axial cable. The Denon is 9 years old. Watching The Vantage Point, I was unable to pick up DD or DTS sound. I ended up watching the movie on 5-channel stereo.

I have had no issues with the Samsung other than this one (no audio or video dropouts on Blu-ray, HD-DVD or on regular DVD). As a result, I have been reluctant to update the firmware. Do I need to update the firmware or is this a settings issue? By the way, DTS lights up when I play movies encoded with DTS-HD. Thanks.

You need to upgrade to latest 1.3 firmware which addressed many audio issues. I'm not sure what sound track is available on your particular BD. 1.3 added support of fully decoding Dolby TrueHD among other changes.

You may also didn't setup digital audio settings right.

Upgrade and set your digital audio settings to 'Bitstream Re-encode' for your setup.

Foxbat121, thanks for the quick response. I will update the firmware. With any luck, I will not end up with a new issue trying to fix this one.

If I remember correctly, The Vantage Point has a Dolby TrueHD track.

Thanks.

That explains it. With old firmware, you will only get 2.0 from DTHD tracks.
