Concert DVD output question

67.173.157.245

A lot of my concert DVD/BluRays do not have a option for LPCM - just Digital DTS and Dolby (I do not have a multi-channel set up). My question is what is fed to the analogue outs of my Sony Blu Ray when I select a format I cannot support? Or maybe I just don't understand all this format stuff.

DTS and Dolby Digital, the lossy version of each company's formats, must be decoded by every Blu-ray player.

Most players these days will decode DTS-HD Master Audio and Dolby TrueHD, while earlier players may not. If a player doesn't decode these two lossless formats, there's a way around this for audio.

DTS-HD Master Audio is built around the core + extension method. The core is the lossy part and the extension contains the rest of the data to make it lossless. Players which cannot decode the extension part of the format will play the lossy part, ignoring the lossless extension.

Dolby TrueHD is accompanied by a Dolby Digital track. If the player can't decode the Dolby TrueHD track, it will default to the lossy Dolby Digital track.

For analog multichannel output, should your player not be able to decode a lossless format, see the info above. As for analog 2.0 output, each multichannel track has mixdown instructions for the decoder.

The player will decode what it can. More than that one cannot say without reading the user's manual. There's usually an explanatory chart in it.
