1. A multicast system, comprising:
- a multicast service module; and
a multicast processing module for subscribing to the multicast service module;
wherein the multicast service module sends a subscribe response to the multicast processing module, and transmits data to the multicast processing module via a unicast frame; and
the multicast processing module further identifies whether the multicast processing module itself is a data initiator according to the subscribe response, and receives the data from the multicast service module in a multicast mode if the multicast processing module is the data initiator, or receives the data from the multicast service module, by discarding unnecessary data and only keeping required data, in a promiscuous mode if the multicast processing module is not the data initiator.

Abstract
A multicast system is provided. The multicast system includes a multicast processing module and a multicast service module. The multicast processing module is for subscribing to the multicast service module. The multicast service module is for sending a subscribe response to the multicast processing module, and for transmitting data to the multicast processing module via a unicast frame. The multicast processing module is also for identifying a data initiator according to the subscribe response, and for receiving the data from the multicast service module in a multicast mode. A multicast method utilized in the multicast system is also provided.

6. A multicast method utilized in a multicast system, the multicast system comprising a multicast service module and a multicast processing module, the multicast method comprising:
-
the multicast processing module subscribing to the multicast service module; the multicast service module sending a subscribe response to the multicast processing module; the multicast processing module identifying whether the multicast processing module itself is a data initiator according to the response from the multicast service module; and the multicast service module sending the data to the multicast processing module via a unicast frame, and the multicast processing module receiving the data from the multicast service module in a multicast mode if the multicast processing module is the data initiator, or receiving the data from the multicast service module, by discarding unnecessary data and only keeping required data, in a promiscuous mode if the multicast processing module is not the data initiator. - View Dependent Claims (7, 8, 9, 10, 11, 12)
