The dynamic UI system of the present includes at least one legacy device, a proxy for registering and managing the at least one legacy device and supporting a dynamic remote control user interface using a multi legacy device control protocol, and an edge peer for downloading the dynamic remote control user interface from the proxy and requesting control of the at least one legacy device to the proxy.

Abstract: Disclosed is an apparatus for purchase and delivery of entitlement in an IPTV broadcast system according to an embodiment of the present invention that includes: an entitlement purchase environment provider providing a charged broadcast contents list to the purchaser so that the purchaser can select delivery target contents and providing an IPTV broadcasting service subscriber list to the purchaser so that the purchaser can select one or more entitlement delivery target subscribers to which the entitlement for the delivery target contents is delivered; an entitlement generator receiving information on the delivery target contents from the entitlement purchase environment provider, and then generating the entitlement for corresponding broadcast contents; and an entitlement transmitter delivering the entitlement for the delivery target contents to IPTV settop boxes of the entitlement delivery target subscribers on the basis of information on the entitlement delivery target subscribers.

Abstract: A settop box based on an IPTV according to an embodiment of the present invention includes: a home network interface communicating with one or more mobile terminals; a terminal profile manager acquiring and managing a terminal profile from a mobile terminal connected through the home network interface; a contents converter converting contents received from an external contents server through an external network to mobile contents suitable for the corresponding mobile terminal on the basis of the acquired terminal profile; a contents storage storing the contents converted by the contents converter; and a transmitting/receiving controller performing a processing operation to extract the mobile contents stored in the contents storage and transmit the extracted mobile contents to the mobile terminal through the home network interface in accordance with a request from a user.

Abstract: An edge peer device, includes a first peer device connection management unit for allowing the edge peer device to participate in a peer-to-peer (P2P) network, and establishing a pipe connection to other edge peer device or the PAN gateway device to transmit or receive contents; a first peer device authentication unit for performing authentication of the edge peer device and PAN gateway device; and a first advertisement management unit for generating and storing advertisements and indexing the generated advertisements to transmit the indexed advertisements to the super peer device. Further, the edge peer device includes a first PAN device management unit for requesting and receiving a list of PAN devices from the PAN gateway device to manage the PAN device list; a first PAN service management unit for managing and providing services included in the PAN device list; and a first P2P communication unit for performing P2P communication with the super peer device and other peer devices.

Abstract: A content redistribution system based on a peer-to-peer (P2P) network includes: a content management terminal that, being a peer of the P2P network, decides for redistribution of contents based on characteristic information included in the contents received via a heterogeneous network; and peer terminals to which are distributed the contents decided for redistribution according to data transmission regulations in a community group on the P2P network.

Abstract: A secure communication system includes: an external peer terminal for generating a security group and participating in the security group by connecting to a peer-to-peer (P2P) network; and a legacy terminal connected to a local area network. The system further includes a gateway apparatus, connected to both of the P2P network and the local area network, for enabling the legacy terminal to participate in the security group.

Abstract: A method of creating a security group over a Peer-To-Peer (P2P) network is disclosed. An invitee terminal attaches a public key to a peer advertisement in which its own identification information is encrypted using its own private key, and then sends a resulting peer advertisement over the P2P network. An inviter terminal, which has found the peer advertisement, encrypts a group advertisement, including group information about the security group, using public keys of the corresponding invitee terminal, and then sends a resulting group advertisement to the invitee terminal desired to be invited to the security group. The invitee terminal decrypts the group advertisement using its own private key, and participates in the security group using the group information.
