Abstract: An internet terminal, which includes a communication unit for sending and receiving packet data, an encryption unit for encrypting and decrypting packet data, a packet generation unit for generating packet data to be sent to a server apparatus, a protocol determination unit for determining a communication protocol to be used between the internet terminal and the server apparatus, a control request reading unit for reading in packet data and a control request packet that includes a control request, a control unit for receiving control information and controlling the internet terminal or a terminal apparatus accordingly. Further, the internet terminal includes a server certificate authentication unit for authenticating the validity of a server certificate sent by the server apparatus, a client certificate management unit for sending a client certificate to the server apparatus, and a storage unit for storing a terminal ID and other information.

Abstract: A communication system includes a device and a server connected to the Internet, which transfers communications between the device and a terminal connectable to the Internet via the server. The device periodically transmits a notice packet to the server. The server transmits a connection request packet to the device in reply to the notice packet when a transfer to the device is requested from the terminal. The device transmits a TCP connection request to the server when receiving the connection request packet from the server. The server accepts the TCP connection request transmitted from the device to the server in reply to the connection request packet, to establish the TCP connection. Thus, the server transfers communications between the terminal and the device on the TCP connection after the TCP connection is established.

Abstract: The present invention provides a transmitting apparatus, a receiving apparatus, and a file transfer system, by which processing of transferring a file is efficiently executed, even if the file transfer is temporarily stopped for a long time in the file transfer system in which the transmitting apparatus voluntarily transmits the file to the receiving apparatus. In the file transfer system of the present invention, a sink apparatus, which is the receiving apparatus, receives file data included in a file from a source apparatus, which is the transmitting apparatus, and then stores the received file data. When a size of the stored data is inquired from the source apparatus, the sink apparatus informs the size to the source apparatus. Further, the source apparatus detects stopping of the file transfer. After the detecting of the stopping of the file transfer, the source apparatus inquires the size of stored data to the sink apparatus.

Abstract: Provided is a UI display apparatus capable of easily searching for and identifying a communication device connected to a network, in accordance with a user's preference. A television 201 being the UI display apparatus includes: a communication unit 102 that communicates with a DVD recorder, which is a communication device connected via the network, receives data sent from the DVD recorder via the network, and sends the received to the processing unit 103; a processing unit 103 that instructs the display unit 105 to perform UI rendering based on information stored in a recording unit 104; the recording unit 104 storing the type name of a device the television 201 wishes to display on the display unit 105 among the devices on the network, the type name of a service provided by the device, a function name, and the like; and a display unit 105 that displays a UI such as an icon according to an instruction from the processing unit 103.

Abstract: For server apparatuses which accumulate content files and attached information about the contents, there has not been a means to distinguish items of the information which the server apparatuses permit editing of. Therefore, when a different terminal connected to the network is to modify the attached information about the contents, there has been a risk that the attached information about the contents are disorderly modified. Provided is a mechanism for having a means to clearly distinguish an item which is permitted for modification from an item which is not permitted for modification, and for clearly indicating the distinction to the different terminal through which a remote operation is performed.

Abstract: A server apparatus selects one of communication equipment that has a waiting and reception capability as a waiting and receiving side communication equipment based on waiting and reception capability information on the respective communication equipments, and selects another communication equipment as a connection side communication equipment. The waiting and receiving side communication equipment sets a router apparatus connected to the waiting and receiving side communication equipment so that the router apparatus receives a signal having a destination of waiting and receiving address information, and transfers the received signal to the waiting and receiving side communication equipment. The connection side communication equipment transmits a packet having the destination of the waiting and receiving address information to the waiting and receiving side communication equipment.
