Hi,
I am working with ADV212 chip. I have configured ADV212 for JDATA mode and the NTSC input is a constant colour frame Y = X"23", Cb = X"D4" and Cr = X"72". The configuration part went smooth. I am getting the compressed output from the chip also. The frame structure is same as mentioned in the document "ADV202 Output Formats Rev.0.0 dated 10/10/2005". Please check the attached files. Configuration is as below,
Register | Address | Value |
Base address = X”00057F00” | Byte offset | NTSC System |
VFORMAT + PREC | X”0” & X”1” | X”0000” |
XFORMLEV + UNI | X”2” & X”3” | X”0503” |
CBSIZE + WKERNEL | X”4” & X”5” | X”0000” |
STALLPAR + ATTRTYPE | X”6” & X”7” | X”0000” |
RCTYPE + RCVALUE | X”8” & X”9” | X”0100” |
RCVAL + RCVAL | X”A” & X”B” | X”7A31” |
JKPROG + PICFG | X”C” & X”D” | X”0001” |
QFACT + COD_STYLE | X”E” & X”F” | X”0001” |
My questions are,
1. How shall I confirm that the output is correctly compressed?
2. In the compressed frame the data size is X"13A" but I am getting almost 1256 words in between markers X"FF93" (SOD) and X"FFD9" (EOC). Does it mean anything?
3. I am using Alberio ADV202 player to see the output. But it is giving some pointer error. Is it a correct test? or what should I do to see the frame in player
