Abstract: An apparatus and method for improving performance of a service based on Wi-Fi direct connection by verifying URI information for controlling a P2P client in a device discovery process of a MAC layer when providing a UPnP service function based on the Wi-Fi direct connection is provided. The apparatus includes a message sending unit for sending a device discovery request, a message receiving unit for receiving a response message, including URI information of a P2P client, for the device discovery request, a message analyzing unit for acquiring the URI information included in the response message, and a service controller for performing a UPnP service function based on the Wi-Fi direct connection using the acquired URI information when connecting with the P2P client, wherein the device discovery request is a device discovery request of a Wi-Fi MAC layer.

Abstract: A multimedia sharing apparatus uses a copy of a metadata database of a portable terminal for copying the metadata database stored in a server. The multimedia sharing apparatus stores the copied metadata database in the portable terminal, and reduces an overhead using the stored metadata database when a user searches data. A multimedia sharing method includes requesting a server to transmit a metadata database at a portable terminal, receiving access information capable of accessing the metadata database of the server at the portable terminal from the server, and reading the metadata database of the server at the portable terminal using the access information.
