Blu-ray and Dolby digital decoding

[duckland 23]

Hi everyone .

I was wondering if you can decode dolby digital 5-1 sound from it ? . I was hearing that you need a receiver with Dolby true Hd in It . Is this true do you need a receiver with that setup . I have a Marantz SR-18EX receiver I would like to buy a blu-ray player someday , but I am holding off for now . I play D-VHS and regular vhs format also I no only d-theater has 5-1 sound dobly digital/ DTS Sound .not vhs .


So back to blu-ray players if someone can give me some insight on this matter , it would help me out very much .So what I am asking do the blu-ray dvd's have the 5-1 dobly digital track on them for sound playback in older receivers with dd /dts 5.1 sound .I'm not very sure I no that much about blu-ray .

-DTS-MA, which is the DTS codec on Blu-Ray contains a normal DTS track and can play on any system which can decode DTS. Dolby TrueHD requires a separate Dolby Digital track, which a lot of Blu-rays have (but not all).

-Does your receiver have multi-channel analog inputs? If so, then all you need is a Blu-ray player that has multi-channel analog outs. My receiver is 10 years old (and it will have to be pried from my cold dead hands) and this is how I get full resolution Blu-Ray audio.

-If your receiver doesn't have multi-channel analog inputs, then you can still get and enjoy a Blu-Ray player, but you will have to ensure that there is either a DTS-MA track or a Dolby Digital track which you can typically find in reviews of Blu-rays like on www.hidefdigest.com.

Hope this helps...

I am certainly no expert in this area, but this is quoted from Wikipedia:

For audio, BD-ROM players are required to support Dolby Digital (AC-3), DTS, and linear PCM. Players may optionally support Dolby Digital Plus and DTS-HD High Resolution Audio as well as lossless formats Dolby TrueHD and DTS-HD Master Audio. BD-ROM titles must use one of the mandatory schemes for the primary soundtrack. A secondary audiotrack, if present, may use any of the mandatory or optional codecs.

The way I read this, all blu-ray titles have to support at least one of the 3 mandatory formats that all players must support. So you should never have to worry about a blu-ray disc not supporting at least one of the mandatory formats that all titles are required to have.

My receiver does not support Dolby TrueHD. I was a little worried about this at first, thinking that some blu-ray titles would not be compatible with my receiver. My receiver does however support all three of the mandatory formats, so I never have to worry about any blu-ray disc not at least offering one of the three mandatory formats that all discs must have.

Hi-Def audio formats sent through a standard s/pdif like optical to a standard AVR, will be down converted to DTS, the Blu-Ray player may have settings for this as well.

I think

I believe it is part of the BD scheme that the core codecs (DD or DTS) must be present to ensure backwards compatibility with older HT receivers. If your receiver decodes DD and DTS, you will get that type of surround sound from a BD player via a coaxial or optical connection.

Be advised though, I've seen at least one player that converts everything to DTS in the scenario of not having HD audio decoding capability. If you have a receiver that predates DTS, you'd be hosed for decent surround sound if you get that type of player. Don't remember the brand...Samsung, maybe.
