BroFS: a GPL DSMCC client |
|
 Carousel filesystem are already present in many broadcasts actually, as they are the base for many interactive tv standard actually, both industrial and set by "open" organizations: like MHP, MHEG, Ginga, HBBTV and so on..
Many standards are based on DSMCC but are using few features like simple transfer of the directory and files tree, some like MHP are using more advanced features like dynamic updates and synchronized events.
BroFS is trying to expose all the details about how the DSMCC modules are bringing "objects" to terminals (STB and the like..), so you could appreciate how files can be changed on the fly and how to transfer "synchronized" events from server to clients. OpenCaster is of course the main partner on the server side as a DSMCC server, but we tested it also on aired carousels here in Italy from many broadcasters and vendors.
