Abstract
The present invention relates to a multicast supporting method for AV data in a network such as UPnP AV network. In the present invention, it is checked based on protocol information of an object containing media data whether multicasting of the object is supported and, if supported, a multicast address is assigned to the object to which an IP address has not been allocated.
