I want to know what will happen if the Fbit is all "0" in the EAV and SAV.
Can ADV7390 encode the signal?
Our customer want to know this because other company's device couldn't handle Fbit = all "0" in the past.
Just because the F bit is zero does not imply the resolution is 480p. It just means it is progressive. You need to check the VS, HS and clock timing to determine the resolution. You could be running 480p30 or 480p60, both will set the F bit to zero.
If F bit is always zero, it indicates the source is in progressive mode, no interlaced. Probably sending 480p instead of 480i
Thank you for your answer.
I understood your answer.
I understood that the output will be progressive mode.
At the case F bit is always zero ,the resolution will be 480?
Sorry I think I should research about this but I would really appreciate if you don't mind to help me about this.
Thank your for your answer.
Thank you for your support.
I have another question.
If F-bit is all zero, I think there is no information about which line is it now.
So, I couldn't imagine what kind of picture will output.
Could you give me an advise about it?
Would ADV7390 output correct picture?
Or ADV7390 can't output correct picture?
The F bit is derived from the H & V sync timing. Look at NTSC timing to see how they determined the field indicator.
What timing goes into the ADV7390 comes out of the ADV7390.
