hello,

     I have a question about the test pattern of the ED.

     so, I want to generate a test black bar with YPBPR ,I set the register

0x00     ->     0x1c 

0x01    ->     0x10

0x31    ->     0x05

0x02    ->     0x24

      nothing on the screen,

 

 

     and I set the NTSC test black bar

0x00     ->     0x1c 

0x82    ->     0xc9

0x84    ->     0x40

     it is sucessfull

 

 

    are there some differents about  ED and SD in the hardware ?
