MITv - a solution for an interactive TV based on IP multicast over satellite

MITv is a proposition for interactive television to be deployed using an association of current distribution television systems (e.g., satellite DVB-S, cable DVB-T, TV over xDSL, etc.) and classical Internet infrastructure. MITv makes use of the natural association between broadcasted TV programs and associated interactive contents to manage replication of those contents over an ad-hoc infrastructure. The replication phase can be based on IP multicast over satellite service, providing a high performance and realistic way to convey the interactive content over the geographically distributed replication units. The proximity between replication units and end-users then allow a very high quality for interactive media presentation by way of an access network such as xDSL. The MITv system was entirely developed and tested in real conditions through a satellite/xDSL network emulator.
