IPNC DM368 hang up. Noisy Image input...

Dear Mr/Mrs,

I'm testing IPNC DM368. And there is a problem.

CMOS imager of the Micron was changed with our customized FPGA.

When output of FPGA is very noisy , IPNC hang up. 

Following is my test results.

1. VBR & Noisy image input  => hang up

  2. CBR & Noisy image input => hang up

3. OFF rate control & Noisy image input => run correctly...

Other settings for testing are

- Codec : H.264

- Stream type : single

-Resolution : H264:D1

-Frame rate : 30

-Bit rate : 4000 kbps.

With CE_DEBUG=3, I have attached log file of IPNC.

Until 106 sec , FPGA outputs normal image.

When about 107 sec, it outputs very noisy image.

How can I solve this issue?

Best regards,
