The present invention provides an apparatus and method for matching protocols of embedded audio/video (AV) contents. The apparatus includes a remote user interface (RUI) server which receives uniform resource identifier (URI) information of AV contents embedded in user interface (UI) data and protocol information of the AV contents; an RUI client which receives the UI data, which was created using the URI information and the protocol information, from the RUI server; and an AV control point (CP) which receives the protocol information and a control request command for the AV contents from the RUI client, matches protocol information obtained from a media renderer with the protocol information received from the RUI client, and performs a control operation on the AV contents.
