[Mp4-tech] Graphics via Mpeg4?

[Pritchard, Alan]

Hi All,
We at ESPN have already managed to set up a 'live' graphics playout
system, where clean video is overlayed with graphics according to the
channel/language in which the material is played out, and some degree of
schedule-related graphics automation (promo appointments, genre-related
bumper backgrounds, automated menuboards etc) and it's always been one
of my wishes to explore using mpeg4 to extend the insertion of these
graphics, at least the text part, to the receiver.
This way our European cable feed could have graphics in all the
destination languages inserted at the head-end. 
Does anyone know of such an implementation already in the field, or
anybody working on something similar?
Thanks,
Alan Pritchard
