audio delay when using 3dtv play and a projector What are my options to fix this.
I have a samsung un55d8000 3dTV and it works great with 3dtvplay, but I had to sort issues with audio delay caused by the displays frame interpolation engine. I had been pushing audio right to my amp from the computer but to do that, you get early audio of course. The sound coming out of the tv is in sync because audio and video are both delayed the same amount. So, the solution is, push audio out of the TV and into the amp. That ok for a display that is next to my amp. If i get a 3d projector that does the same type of thing, its going to suck to run the spdif cable out of the projector all the way back to the amp. I suppose I could fix all these issues if the computer knew what the correct delay for the TV or projector was. That way I could just push the audio from the computer to the amp, set the delay and it prevents a return from the final device. What are people doing out there for this issue? I dont see any technology that fixes this short of the ARC feature of hdmi. Unfortunately, my amp doesnt do ARC, so I am wondering if I need to run this extra line if I buy a new 3d projector.
The 3d on the samsung d8000 is amazing by the way. THe big question i had before I bought it was, do the glass remain at a high refresh even though the signal going in is just 24hz and the answer is yes, and that is due to this frame interpolation delay where they make all the extra frames to get you up to a higher refresh rate. It also smoothes out the motion in 3d as well as 2d and improves the quality of the picture considerably.

First of all lets try to differenciate the refreshrate and the image rate.
If the computer renderint the hitghest 3Dplay 1080p framerate of 24hz framepacked over hdmi.
You start with 2x 24hz image sequences.
Even if the TV would display them exactly as rendered the shutter glasses (assuming active TV) would run at a much higher refreshrate.
The TV most likely have the option of interpolating inbetween frames to create a smoother experience. To do this the TV needs access to both the current frame and the future frame.
When the refresh rate is only 24hz that means a guaranteed image delay of over 40ms which only increases as the image is pipelined through the rest of the image processor.
You already know that your TV is very far from zero delay.
While it's probably hard to find an option that works perfektlly regardless of input source you should be able to setup really high delays in your reciever for all speaker outputs.

Thanks to everybody using my assembler it warms my heart.
To have a critical piece of code that everyone can enjoy!
What more can you ask for?
