1. A device for retransmitting a received IP media stream broadcast, said [ the ] device comprising:
a communication module adapted to receive from a media presentation appliance a request for a given IP media stream; and
a stream generator adapted to convert, in response to the request from the media presentation appliance, one single appliance specific version of the requested media stream from multicast to unicast, and to retransmit with a delay the converted unicast, appliance specific, version of the requested media stream to the media presentation appliance,
wherein a delay time for the delayed version of the requested media stream is determined to reduce zap-time associated with presenting the requested IP media stream at the media presentation appliance at least partly based on a timing parameter of the request received from the media presentation appliance, and
wherein content in the unicast appliance specific version of the requested media stream is substantially identical to content in the multicast appliance specific version of the requested media stream [ , ]
the device further comprising:
an appliance specific media stream generator adapted to derive from a first multicast media stream one or more uni-cast [ unicast ] media streams or a second multicast media stream,
wherein the device is further adapted to track a status of the derived one or more uni-cast [ unicast ] media streams or the derived second multicast media stream.
