Hi folks,
I'm trying to debug a problem where a video device is connected to a VIP port operating in 16 bit mode on a DM8148.
The video device can use embedded or discrete sync and I'm having problems with embedded sync.
In order to debug the problem, I have configured the device to generate both embedded and discrete sync. What I am then doing is configuring the DM8148 to use discrete sync (HSYNC and VSYNC only). This is making the VIP capture the complete frame 1650x750 @ 720p including all the blanking regions. I am storing the captured data in a file.
My question is should I be able to see the embedded sync words in the captured file or does the VIP strip them out on the way through?
I have been unable to find any documentation on what the expected sync words should be, but I am assuming that they should consist of the sequence 0xFF, 0x00, 0x00 and 0xXX (where XX depends on the value of F,H and V) and that these sequences should appear in one or other or both of the Y and CbCr channel?
Thanks in advance,
Terry
