[Mp4-tech] FW: Captioning for MPEG

[Rob Koenen (MPEGIF)]

MPEG-4 techies,
Does anybody know any products that can extract closed captioning from the
analog broadcast signal before encoding, encode video/audio/text in MPEG-4,
and put it together as a anolog signal again at the decoder? See question
below. Please respond to list and Dave as in CC.

Rob- As a follow-up to our conversation, I'm looking for a solution
where broadcast affiliates could load down (via FTP) an MPEG 2 or MPEG 4
file of a 30 or 60 second PSA commercial and maintain the closed
captioning, so it can play back at a broadcast TV station with the
closed captioning in tact. Please let me know ayone who could recommend
a solution. Thanks, Dave.
