Connecting Blu ray player to non hdmi receiver

by erna8370 / November 27, 2008 8:58 AM PST

I just bought the panasonic bd-35 blu ray player to go with an older dolby digital/dts 5.1 Yamaha receiver that has a digital optical and a coaxial input but no hdmi inputs. Cnets review of the bd-35 says 'the DMP-BD35 has onboard decoding for all high-resolution soundtrack formats, including Dolby TrueHD and DTS-HD Master Audio, so you don't need a new receiver to take advantage of the improved audio quality.' Other websites say a digital optical cable can't send the trueHD/DTS-HD audio information. Which info is correct?

Will my non hdmi receiver with an optical cable be able to give me digital trueHD and DTS-HD sound quality or not? please help.

I believe both info are correct from what I understand.

My guess is that one is referring to the optical connection from the tv to the receiver.

hey, give it the hearing test; hook it up and enjoy. True or not true doesn't matter. What you got is what you have.

optical / coaxial may not handle the signal

I also hav ea non-HDMI Yamaha receiver. I have been doing some research on the same issue. I found a nice article explaining how the decoding and transferring works:

http://www.highdefdigest.com/news/show/1064

If you read far enough it says in a nutshell that : Toslink (Optical) or Coaxial SPDIF - SPDIF cannot carry a TrueHD signal. If using this connection type, the player will automatically revert to playing back the standard Dolby Digital AC-3 track instead.

I don't think it will sound bad, you will just not be hearing the HD Audio,

when its saying onboard decoding, it probably means that this decoded info is still sent via hdmi.

there were indeed receivers made that could handle mch pcm via hdmi, but without onboard decoding.

just enjoy the improved video for now, and just use SPDIF. The video improvements completely blow away the audio ones, imo, and i got into this stuff for the audio...
