摘要： The disclosed communication node has a function for recognizing one communication node on the first network as one of constituent elements in own communication node, and a function for disclosing an own configuration information regarding the constituent elements as recognized above, to another communication node on the second network. Also, the disclosed communication terminal has a function for disclosing functions in the own communication terminal as Sub Units in an AV/C (Audio/Visual Control) protocol executed on an IEEE 1394 bus, and a function for receiving at least a part of information regarding Sub Units existing in the communication node on the second network with which it is communicating. Together, these communication node and communication terminal make it possible to transmit various information transferred on the IEEE 1394 bus, to the radio node that is connected by the radio interface, and it becomes possible to execute the data communications as if the connection to the IEEE 1394 bus is made by the radio interface.

摘要： Under a multi-task environment, a tamper resistant microprocessor saves a context information for one program whose execution is to be interrupted, where the context information contains information indicating an execution state of that one program and the execution code encryption key of that one program. An execution of that one program can be restarted by recovering the execution state of that one program from the saved context information. The context information can be encrypted by using the public key of the microprocessor, and then decrypted by using the secret key of the microprocessor.

摘要： A wireless network system capable of controlling highly efficient transfer of AV data by an upper application, using information indicating a wireless link condition that varies dynamically is disclosed. In this wireless network system, a wireless terminal and a wire gateway apparatus each store collected wireless link condition information in a descriptor. An upper application on the wireless terminal reads the descriptor at said terminal device and obtains wireless LAN link condition information. The wireless gateway apparatus makes notification to a wireless terminal of a VTR, for example, that actually exists in a 1394 terminal as if it existed as a sub-unit in the local terminal device. The wireless terminal accesses the collected wireless link condition information and selects a AV/C command to be sent to the VTR sub-unit of the wireless gateway apparatus. The wireless terminal transfers the play command for playback to the wireless gateway apparatus. The wireless gateway apparatus transfers the play command to a VTR sub-unit within a terminal on the wired network. In accordance with this action, the VTR sub-unit within the terminal on the wired network starts transfer of AV data.
