Hey all.
as I posted in another thread, my HDMI port blew on my TV. so...i have to hook up component on the video side... but is there a difference in audio format availability ie..true hd etc.. if I use the digital coax or optical to input sound from my devices into my AVR or should I definitily use the 1.3hdmi to input the sound portion at least.
my goal is to get the new/best hd sound from my bluray etc.
Thanks.

To get the new lossless audio formats, you must connect by HDMI, or use a player that has 5.1 or 7.1 analog outputs. You will not get those formats using the optical or coax outputs.

+1 this is all correct. I've been doing research on the new dolby and DTS formats.. either HDMI 1.3 or analog audio are the only way to get the newer formats.PolkFest 2012, who's going>?

thanks,
hooked up all the wires, have true HD now...sounds the same to me...Im clueless.Rti10 front, csi5, Rti6 surrounds, PSW505, B&K200.7s2, Onkyo705. -

I'm using analogs to get True HD which means the source controls the output. This also means that in some movies, you need to choose True HD over the default Dolby Digital in the Audio setup (Not the player setup, the movie audio setup). Be sure to do this for each movie before playing. -
Just to clarify, we DO need to use the 6 RCA jacks off the dvd player to get newer DD & DTS formats????I refuse to argue with idiots, because people can't tell the DIFFERENCE!

No, you have to use analogs if you do not have a receiver that is HDMI 1.3 compliant such as mine. If you have a receiver that is 1.3 compliant, then you can get True HD thru HDMI or analogs. In either case, you need to make sure the DVD audio is set to True HD instead of Dolby digital. Some movies don't give you the option, some do. -

Almost correct. He only needs a reciever with HDMI 1.2. It will still decode in the player, but will be sent as 5.1 PCM over HDMI. The advantage of new recievers with HDMI 1.3 is that it will allow for decoding in the reciever, but only if the player will bitstream over HDMI, and only a couple of models do that so far.
Confused yet? -
Confused yet?
Absolutely.
I'm guessing that in 6 months the latest formats on receivers and bitstreaming capability on HD-DVD players will be standard, correct?
Are we still in the "early adopter" phase of HD audio?HT/2-channel Rig: Sony 50 LCD TV; Toshiba HD-A2 DVD player; Emotiva LMC-1 pre/pro; Rogue Audio M-120 monoblocks (modded); Placette RVC; Emotiva LPA-1 amp; Bada HD-22 tube CDP (modded); VMPS Tower II SE (fronts); DIY Clearwave Dynamic 4CC (center); Wharfedale Opus Tri-Surrounds (rear); and VMPS 215 sub

Absolutely.

I'm sure it will become standard on most new model recievers, but it will probably be at least a year or two before all manufacturers have it. For instance NAD just came out with new 1.3 recievers and a pre-amp, but they do not decode the new formats. -
as far as I know, the onkyo receivers that decode trueHD and dts hd will accept over fiber optic and digital coax. Whether or not your player will output the bitstream out of those connections is another story. I'll test this out tomorrow when I'm at work to confirm it....Logically, it should work. HDMI would make sense for a receiver without the onboard decoders, but for one with it, then it should work....in theory. Also, the new receivers must be set for 6.1 or 7.1 to accept the signals. As I said, I'm about 80% sure about Fiber and Coax working, but I'll keep you guys posted.....

It won't work. The coax and optical cables cannot handle the bandwidth of the lossless codecs. I have the PR-SC885 btw.
I don't know how Blu-Ray handles it, but with the various HD-DVD players, when you use the optical or coax connection,True HD and DTS HD are down converted to either 1.5mbs DTS or 640kb(?) Dolby Digital depending on which model. I know it's DTS for the A2 and DD for the A3 for instance. It's still supposed to sound a little better than the standard DTS or DD tracks, but it is not lossless.
Besides, all receivers that have onboard decoding for the new formats also have HDMI 1.3, so what would be the point?
And you don't need to set the speakers to 6.1 or 7.1 to get the signals, 5.1 works fine. But you must connect by HDMI to decode in the reciever. -
Ok, check this out: I hooked up a panasonic bluray player, which will bitstream out the DTS-HD track, up to an Onkyo TX-SR605 today, and could not get the receiver to play in DTS-HD. Tried all combinations of settings, and all I could get was PCM Multichannel, which is basically the Bluray player decoding the DTS-HD. The Sample Rate was only 48khz. The only thing I can think of is that I was using a low quality HDMI Cable.
Also, I'm pretty sure Fiber Optic and Digital Coax cables have more bandwidth than HDMI when it comes to audio. HDMI is really just a 10 conductor cable, much like a CAT5 cable with a different connector on it. The wires inside are oxygen free copper with a few layers of insulation. The issue with them not working I believe is due to stupid copyright reasons. -
Ok, here is my confusion. I'm thinking of getting a new receiver for A/V switching to handle my HD DVD, Blue Ray, HD Satellite, and Apple TV (all 4 have hdmi outputs). So I'm guessing I'll need to find a receiver that has 4 hdmi inputs (not sure if any do yet, most I've seen is 3 inputs). Regardless, my HD TV does NOT have hdmi inputs; only component inputs. Will this still work or do I 'have' to have a TV with hdmi inputs? Do they make a cable that is hdmi out on one end (from the receiver) to component in (3 rca jacks) for video in to the TV? If not, seems a shame I can have all these hdmi compliant devices but a TV (which is used as a monitor only) that can't use them.

They do not have the same bandwidth. A coax commection only has one wire, compared to HDMI. But you are right, some of it was done for copyright protection.
As far as your trouble getting DTS HD, are you sure that the disc has a DTS HD track? Also, you must select the DTS HD track from the disc's setup menu before playback. Most disc's will default to plain DD. -
lol, I definately checked that. The menu of the DVD says "DTS-HD", but it only comes out as DTS. And while HDMI has 10 wires, a bunch of that is for video, HDCP handshaking, and Two-way device communication (for stuff like panasonic's EZ-Sync or sony's bravia home theater lync).

Classic problem: HDMI is digital, Component is analog. You do need a tv with HDMI, cause receivers won't downscale HDMI to component, or a device that will do that and maintain the proper resolution (HDCP). Sounds like your TV is dated. No DVI connections either? Is it truely a monitor, or is it a TV used as a monitor? If its truely a monitor, you might have a TV with swappable boards, like the pioneers and panasonics.
Component Video is still a damn good connection. If you found a receiver that had plenty of component video inputs on it, then you'd be in good shape. Most have at least 3. Also, on some receivers, you can assign input to take its digital audio from HDMI. Might still work even if you are using component on that input as well (this would be useful for taking advantage of the DTS-HD and DD TrueHD tracks). -

I wasn't aware there were any receivers that you could assign the inputs from HDMI (from AV sources) and then still output the audio separate from the video. Would I then still use the component outputs for video from those sources in addition to the hdmi?
My TV is a Mits 65" rear projection TV. It does not have dvi or hdmi. Only S-video and component. -
possibly. I know the digital audio selector on onkyo's with HDMI cycles through Fiber Optic, Digital Coax, and HDMI as a digital audio source in the same menu. So in theory, you would use both component and hdmi.
I'd recommend buying a new TV though. I'm guessing you swear by that TV though if you haven't even proposed the idea in this forum of getting rid of it. But keep in mind that when bluray first came out, the first players that came out were only going to put out 480/576p from component, but they couldn't work out the HDCP and other copyright issues, so they let it be.
