1. A method of supporting multicast of video and/or audio content in a network, comprising the steps of:
- (a) determining based on protocol information of an object whether or not multicasting of the object containing media content is supported; and
(b) if it is determined that the object is multicast-support, assigning a multicast address to the object to which an IP address has not been allocated.

10. A networked apparatus for providing video and/or audio content in multicasting manner through a network, comprising:
-
a media server that stores objects containing media contents; and
a control point, running on a device on the network, that allows an object in the media server to be streamed in multicast manner to a media renderer, wherein either the media server or the control point assigns a multicast address to the object whose protocol information is indicative of multicast-support and to which an IP address has not been allocated. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
