ADV7181C inverted Teletext

Question asked by Jochen2 on Jan 7, 2013

some customers use inverted Teletext (iWST). 'Normal' teletext is decoded (streamed as CCIR656) with the ADV7181C correctly, but if iWST is used in the CCVS input signal, the data is shifted by 1 - 5 bits (it seems to be randomly shifted). Is there any possibility to detect and correct that?
