My Customer use 3 chip of ADV212  ,and sometimes stop decoding.

If it's used for about 1000 hours, a DREQ signal doesn't reply any more.


Combination of wavelet transformation and the resolution was doubted, but it seems no problem.

(A chip for each of resolution is used at Y,C (Cb/Cr) and K in 1920 x 1080 (60i).)


I checked data of EZ and i find, ADV212 JPEG2000 problem? I have my hands full! 


It say that ”Monitor the price of the SWFLAG register and SCOM [3:0]."


Isn't there material of SCOM [3:0]?


A signal of DREQ is the phenomenon which doesn't come any more, and would I be able to receive advice?
