    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 ?
