Hi,

 

What settings for VID_STD and CP_V_FREQ should one use for 1080P25 and 1080P30 when PRIM_MODE = 0001 (COMP)?

 

According to Table 14 on page 61 in the ADV7802_HW_RevB.pdf, one should use VID_STD = 01100 and CP_V_FREQ = 011 for SM274 -9 (System No 9, 1920 x 1080/25/P) and VID_STD = 01100 and CP_V_FREQ = 011 for SM274 -7 and - 8 (System No 7, 1920 x 1080/230/P).

 

I tried these settings, but I detect an interlaced video signal on the output instead of progressive (i.e. the field flags are not behaving as expected). And it says 1080i 1x1 in table 14 in the mode colum.....
