Yes, they do exist.

We run a commercial 300+ channel IPTV multicast-based service, and many
of our channels have CC.  It typically does need to be encoded as a data
stream, just as the audio and video do, and VLC does recognize those
AFAIK.  Normally, the encoder recognizes the CC and encodes it, using
either or both CEA-608 (Line 21 data, not typical) and CEA-708 (also
known as DTV or HD closed captions).
