Is there a simple way to build a configurable TOSLINK delay? Answered
Some TVs require 3 frames for the interpolation of tweening frames (and then there is also processing overhead time). With frames coming in at 1/24th for film or 1/30 for tv then 2 or 3 frames out of sync can look horrible and add several hundred millisecond delays. The TV's SPDIF is already delayed and works great, but downscales DTS to stereo (I hate you Blu-Ray!). So I need a delay on optical that bypasses the TV to get DTS to work.
I've done some research and found that the following products do a audio delay to help with sync problems with LCD TV (esp 120Hz) and TOSLINK on older receivers that can't add the required lip-sync delay.
The consumer level delays are made by:
Felston - $250
J.S. Technology (UK company) - £79
Alchemy2 - $400-$450
Bottom line, what does this take to develop: A TOSLINK receiver and transmitter. A MPU that can receive the serial stream store it in internal memory and read at a configured offset to transmit. Has anyone take up a project like this and be willing to post the intructions here. I hate to buy a new receiver just because of this, that would be wasteful.
