The DSM-CC ObjectCarousel protocol is a broadcast protocol on top of MPEG2. It is used for transmission of filesystem hierarchies over a MPEG2 channel.

Like other protocols (NFS, SAMBA etc. via IP), the ObjectCarousel protocol allows mounting of external filesystems that are broadcast within a MPEG2 program.

Basically, to mount an ObjectCarousel, of course you have to know where to find it. For example, given a stream location on dvb://ONID.TSID.SID, you have tune to this service and check some (P)SI tables for presence of an ObjectCarousel there (which tables is the subject of the next layer).
