ADV7441A vbi processor

    I have an implementation question on the   ADV7441A....

It has a cvbs processor as well as a hidef  processor. We need to be able to
have the VBI processor extract  closed captioning or teletext/wss from the cvbs input
while the hidef section is receiving and decoding video (either HDMI or component) and 
have the extracted VBI data carried with the video data out  over the pixel output
port as ancillary data packets (in the  same fashion that an ADV7180 formats and outputs VBI
ancillary  data).  Note that the cvbs source and the hidef source will be synchronous.

Can this part do that ??
