I need your good advice!
Our customer have met the trouble as following.
When the customer had developed with ADV7842KBCZ-5P(=without HDCP key), then the customer could watch the sample image.
The recorder what they used is DMP-BW800/Panasonic.
The customer had played DVD-disk SD(VGA) on DMP-BW800/Panasonic. This is no problem.
But when the customer replaced from ADV7842KBCZ-5P to ADV7842KBCZ-5(=with HDCP key), then the customer could not get the test-image on DMR-BRT300/Panasonic.
It only shows "HDMI" on the window of DMR-BRT300. But no test-image on there. It seems to recognize signal.
But the customer could watch the test-image on BD-W1500/SHARP as same condition. It seems no problem.
The registers for EDID/HDCP have been set as default.
EDID(address A0); Set by external ROM
So the DDC data that is catched by ADC is only HDCP(address 74). On this condition, the function of EDID/HDCP is default OK?
Please advice us the register setting for with-HDCP model.
Otherwise what should we confirm about this trouble reason searching?
Thank you in advnace, Kaos
