Abstract
A method of and an apparatus for transmitting a universal plug and play audio/video (UPnP-AV) stream is disclosed, which transmits a media stream from a media server to an media renderer, using an integrated protocol which combines an universal plug and play (UPNP) audio/video (AV) protocol and a residential Ethernet (ResE) subscription protocol. According to the method, an integrated protocol combining an UPnP-AV protocol and an Ethernet protocol can be used. Additionally, a secured quality of service (QoS) can be provided for the UPnP-AV stream.

12. An apparatus for transmitting a universal plug and play (UPNP) audio/video (A/V) stream, comprising:
-
a control point which transmits a PrepareForConnection message for a media stream transmission, and transmits a control command so that the media stream is transmitted;
a media server which receives the PrepareForConnection message, reserves a resource request, and multicasts the media stream according to the control command; and
a media renderer which, in response to the PrepareForConnection message, prepares for a connection with the media server to discover a service according to an Ethernet protocol, constructs a stream forwarding identifier (ID) using ID information of the PrepareForConnection message, and sets a connection using the stream forwarding ID to receive the media stream. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
