Official OPPO BDP-83 Owner's Thread [technical talk only] - Page 635

I can assure you this is not true--unless you are referring to PLII or Neo:6, both of which are easily switched off. Just which algorithms did you have in mind?

Does anyone know if the 83 supports or could support RIHD (Remote Interactive over HDMI) given it's current hardware?

My setup Oppo BD83 > Onkyo 906 > Sharp Aquos. I set the Oppo to Bitstream. Playing back BlueRay and DVD movies on any resolution settings, I get NO lights, which on the Onkyo means the text display of the Audio codec from the disk source, and by "icons", I mean the little "speaker box icons" on the Onkyo front display, I only see 2.1, my two front mains, and the subwoofer. I have seven speakers hooked up correctly, Audussey corrected etc. I understand that if I choose "SOURCE > THROUGH" on the Onkyo, the Oppo is doing the decoding and therefore the Onkyo would NOT display such info and that is FINE and UNDERSTOOD! Again, movies play fine and using one of the many listening modes on the Onkyo I can expand 5.1 to 7.1 and get correct audio on all 7.1 speakers.

HOWEVER my GOAL was to setup the Oppo as a "transport", and see what the Onkyo could do with the Video output via it's own Reon chip as well as hopefully see the lights/text of the audio codecs from the source DVD/BLUERAY, on the Onkyo display for once. I ASSUMED the only was to make the Oppo a "transport" was to choose it's "Source Direct" mode, which for most blueray disks means 23.97/24 fps output, and I quickly learned my two year old Sharp display does NOT support. AGAIN, if I choose 1080P resolution output on the Oppo letting it do the processing, the Onkyo has NO problem PASSING THROUGH that signal, as you say it does 1080p 60 hz.

RELATED is I got the audio disk in the mail from Oppo, and with the same bitstream settings, I played the audio tracks and NO icon/text info comes on my Onkyo display. I tried setting the output on the Oppo to PCM, same results. I'm tearing my brain trying to figure out if I missed a setting somewhere on any device. I hope I've made this more clear, as the messages get divided up and lose content as the thread GROWS. Thanks for the help, I'm lost.

I'm 99% sure that the RIHD you are referring to is Onkyo's name for CEC, which the BDP-83 does in fact support. I've tested it, and the BDP-83 can communicate via CEC with both my Onkyo 885 processor and my Sony HDTV. Don't ask why Onkyo and other manufacturers insist on providing company-specific brand names for CEC even though CEC is part of the HDMI spec (and therefore not company-specific).

I use Bitstream for everything, even tested PCM output on the Oppo. I doubt the Onkyo 906 is at fault, as I've seen my speaker icons become active when I am flipping through HDTV "Air" channels and select the Optical feed from display to AVR. I have to assume it's "USER" error, meaning ME at this point and something I am missing. Thanks for the feedback.

I had to look that up. Is different than HDMI CEC?

I'm not sure. I'm just learning about CEC and RIHD in my search for a new receiver. Information is sparse on whether the compatibility is there between manufacturers. I'm not sure why they seem to name CEC something other than CEC unless they do something different with it.

the answer is no it does not. as wmmclain said, it has a combined bitrate meter which tells you absolutely nothing because who knows what the audio and video bitrates are separately. one can only hope oppo will come to their senses soon and make this simple fix.

Foothill,

You forgot about that little "speed" thing.


Respectfully,
Willie

This is a must have for me, sometimes I obsessively watch the PS3's meter for far too long!

Hi Roger,

There is a long discussion about this issue in the av8003 thread..Marantz representatives brought that issue...

According the wiki article on HDMI (http://en.wikipedia.org/wiki/HDMI):


All I ever hear about CEC are complaints on the order of "what the hell is this?"

-Bill

thought it only had to do with analogs with the downmix thing?

As has been stated several times before, it's not a simple thing at all. It's also not high on the list of priorities. If it were a simple thing it would have been done. The bit meter is showing the rate of the compressed and combined data as it comes off the media. A split meter would come from a different place, and it's not clear whether this is possible in this machine. Talk to Oppo directly about this if you want more information rather than sniping about it here.

well email oppo like i did. in fact i will probably email them again at some point about it. all they need to do is make it a double push on the info button, just like the pioneer 51 does. with the 51 you only get the bit rate meters if you push the button twice. it defeats oppos excuse that they "tried to make the info screen unobtrusive"..whatever, just make it a double push then anyone that wants to leave it on the screen with one push can do so and anyone that wants more info can push it twice.

Be aware that when listening to any source at 96 khz sampling or higher that if played through an Audyessy enabled receiver the Audyessy does not function properly as it also runs its' software at 96KHZ. Oppo is aware of this issue but not really their problem.

I did see the wikipedia article, but I still don't know for sure and there is very little information on what exactly is implemented by RIHD and how much of that is supported in OPPO's implementation of CEC.

According to the manual:


This still doesn't tell me much.

Basically, I'm looking to upgrade my receiver from a late 90's Yamaha rx-v995. I want to put everything in the closet so I'm trying to see if some of these types of features help me do that. Its a pita to pick receivers these days with so many features and not one of them having everything you need. One of the items I thought about not putting in the closet for convenience was the 83. So, this made me wonder if I had the 83 in the room connected via HDMI to my receiver in the closet I might get enough automation from this CEC/IRHD or whatever you want to call it.

Alternatively, I can do serial, Harmony 900 or IR target and distribution....

If someone has done extensive testing using CEC on the 83 with an Onkyo or Integra unit let me know. I'm leaning towards the Integra 30.1 at the moment.

Thanks much for that info. I found this post saying >>all modes outside of source/pure direct are programmed by Dolby/DTS and it's their algorithm that determines the sound in those modes.<< Now that I see the details, I can assure y'all, it's false, just as I said. Marantz is passing the buck. Neither Dolby nor DTS have any say over what happens in any modes but their own. If there's more info on the nature of these "algorithms" I'd be pleased to know.

CEC is a standard and all these manufacturers' implementations of it conform to that. If you are using a Harmony (or any other universal), you'll probably want to turn all the HDMI control off anyway; universal remotes allow for much better control than CEC does.

This is not true. The limitation on what processes can be accomplished and at what data rates is the DSP capacity of the receiver. Some run out of steam before 96kHz (e.g., Marantz), some handle 96kHz but not more (e.g., Integra/Onkyo), and some will handle it at 192kHz(e.g., the top Denon prepro).

It is not a limitation of Audyssey.

FWIW I don't think that is a true statement if taken literally. From my research so far I understand that while CEC is a standard no manufacturer is required to implement 100% of it or limit their implementation of it to only what is in the standard.

If you know OPPO has implemented CEC to 100% of the standard let me know.

Let's not forget the Anthem D2v.

My understanding is that there is a basic set of functions that they all implement; this includes things like power and input control and basic transport controls. It does not convey all components' IR commands to one other as, say, an IR repeater system does. In my experience, it's a pretty crude system that may have been useful about ten years ago, when you had to buy everything from one manufacturer to get components to play nice together. But now, universal remotes have made the CEC system pretty obsolete. Any receiver you buy these days will probably include a remote that can control the Oppo or any other BD player you choose.

I am using Denon 4308, and my setup is like this:

Oppo --HDMI --> Denon 4308 --HDMI--> Panasonic 50" Plasma
(all three with the most updated firmware)

1080/24P is okay, no matter BD or DVD.

Please make sure you choose A to H only at HDMI option of the Denon AMP, don't choose the option with H to H, which will process the video by the Denon.

Hope this helps.

I was listening to some SACD's tonight that were multi-channel. Here is a question I have. My system is all HDMI 1.3, BDP-83>Denon AVR-3808CI>Panasonic 800U plasma. When I'm listening to multi-ch SACD's my AVR displays multi-ch, as soon as I turn off my plasma I loose multi-ch on my AVR and it goes to Dolby PLII Music. DSD is still lit on my AVR though. What is the cause of this. Is it from HDMI connections?

[quote=jayray;16984692]
And in what category does it fit? I was only giving an example for each, not trying to be exhaustive.

I just took the plunge and ordered this player. Should have it friday. I read the first page with all the firmwares, official, public beta and what not. And so without reading through all the other 635 pages of this thread, which seems to be the best and most stable firmware to put on when I receive my player?

Again, there is nothing that says anyone has to implement any of it. You can be HDMI 1.3 compliant with zero CEC.


I think the issue of not having a standard across all manufacturers on what must be implemented and how to do it for compatibility is what makes it appear crude to you. I just read the tech docs on how it works and it's anything but crude. It more feature rich than any IR code due to it's topology.

After reading the specs and white papers I seriously doubt CEC will go anywhere across manufacturers. I doubt many manufacturers will even implement it across more than one of their products using their own CEC devices.

Let's not forget the lowly Yamaha AVRs, which all use 24/192 DACs and DSP. No need to spend a bundle for 24/192 processing.

I have all HDMI 83->Denon2809-> sammie LCDTV and when I just tried that, all that happened was it blanked the audio for a few seconds. I do notice that once in a while when I start an SACD disc the Denon does not show MULTI CH IN. I simply switch the Denon to a different input (ex: TV) and back, which fixes it. Try it and see if that works for you. Yes I would attribute these oddities to HDMI secret handshake.

BTW, does sending DSD sound different to you than PCM? (I assume from your statement you're listening in MULT CH IN & do not use the DSD Direct mode.)
