Yes. This is called transcoding, and the simplest way is to decode
H.264 stream and encode again with H.263 encoder. There are also
smarter ways to do it which can save computation, and those are
an active field of research.
And if you mean if H.263 bitstream is compatible with H.264 in some
direction, no, it's not, as far as I know.
