摘要： PROBLEM TO BE SOLVED: To enable efficient and reliable data transceiving. SOLUTION: An IM server 41 stores information on whether communication apparatuses A to C are connected to a network or not (login state or logout state). When the communication apparatus A in a logon state sends data to the communication apparatus B in a logoff state, the data are once sent to a relay server 42, and when the communication apparatus B becomes a logon state, the relay server 42 sends the data to the communication apparatus B. The relay server 42 negotiates with the communication apparatus A about whether data exchange is possible or not, before the data sending by the communication apparatus A, and negotiates with the communication apparatus B about whether data transceiving is possible or not, before the data sending to the communication apparatus B. This method can be applied to personal computers. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To inexpensively and surely realize communication across NAT (Network Address Translation). SOLUTION: On the basis of the protocol of UPnP (Universal Plug and Play), a local communication terminal A or C to be connected under a router 41 or 43, having a UPnP function obtains an IP address and a port number converted by the NAT function of the router 41 or 43, and registers it in a relay server 63 as exchange information for the communication across NAT. On the basis of the packet obtained from STUN servers 61 and 62, a local communication terminal B or D to be connected under a router 42 or 44, having the UPnP function specifies the IP address to be converted by the NAT function of the router 41 or 43, predicts the port number to be converted by the NAT function of the router 41 or 43, and registers it in the relay server 63 as exchange information for the communication across NAT. The invention can be applied to personal computers. COPYRIGHT: (C)2005,JPO&NCIPI
摘要翻译：要解决的问题：廉价，可靠地实现跨NAT（网络地址转换）的通信。解决方案：根据UPnP（通用即插即用）的协议，要连接在具有UPnP功能的路由器41或43下的本地通信终端A或C将获得IP地址和端口号转换通过路由器41或43的NAT功能，并将其注册在中继服务器63中，作为跨NAT通信的交换信息。基于从STUN服务器61和62获得的分组，在具有UPnP功能的路由器42或44下连接的本地通信终端B或D指定要由路由器41的NAT功能转换的IP地址或43，通过路由器41或43的NAT功能预测要转换的端口号，并将其注册在中继服务器63中，作为跨NAT通信的交换信息。本发明可以应用于个人计算机。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To enable to smoothly recover an operation state even if a normal response to a request of content key confirmation cannot be obtained from a Source apparatus.
SOLUTION: In a situation where a busy state of a Source apparatus or congestion of a network causes delay in response of CONT_KEY_CONF, a Sink apparatus is brought into a non-confirmation state similarly to a case of receiving the response, and permits retry of a request of confirming a content key for only a predetermined period. If it is confirmed that the content key is correct after that, the Sink apparatus can continue to execute decoding processing of reception content.

摘要翻译：要解决的问题：即使不能从源设备获得对内容密钥确认的请求的正常响应，也能平滑地恢复操作状态。解决方案：在源设备的忙状态或网络拥塞导致CONT_KEY_CONF响应延迟的情况下，与接收到该响应的情况类似，将Sink设备变为非确认状态，并允许仅在预定时段内重试确认内容密钥的请求。如果在此之后确认内容密钥正确，则Sink设备可以继续执行接收内容的解码处理。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To properly execute confirmation of a content key even after content transmission procedures for generating the content key have been completed.
SOLUTION: A Source apparatus does not immediately delete a nonce N
c even after TCP connection for content transmission has been completed. Even when a request of confirming a content key is received from a Sink apparatus side after the TCP connection for content transmission has been completed, content key determination can be properly executed. Since the Sink apparatus can acquire a correct result of determination for the request of content key confirmation in executing decoding processing of the received encrypted content, the decoding processing of the received content is not necessarily stopped.

摘要翻译：要解决的问题：即使在用于生成内容密钥的内容传送过程已经完成之后，也能适当地执行内容密钥的确认。解决方案：即使在内容传输的TCP连接完成后，源设备也不会立即删除随机数N c 。即使在用于内容传输的TCP连接已经完成之后从Sink设备侧接收到确认内容密钥的请求，也可以适当地执行内容密钥确定。由于Sink装置可以在对所接收的加密内容进行解码处理时获取正确的内容密钥确认请求结果，所以接收到的内容的解码处理不一定被停止。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To easily communicate with another apparatus via an NAPT. SOLUTION: A local communication apparatus 11 supplies a service request packet to a service providing apparatus 51 for apparatus at first, and acquires a service providing packet via the port 342-1 of a relay apparatus 12. Next, the apparatus 11 supplies a service request packet to a service providing apparatus 52 for apparatus, and acquires a service providing packet via a port 342-2 of the relay apparatus 12. The apparatus 11 calculates a differential value of information of two global addresses included in these service providing apparatuses, adds a value "1" to the port number of the port 342-2 used for communication with the apparatus 52, and forecasts that the port 342-3 is a port corresponding to next communication. This system is applicable to an instant message service system. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To suppress missing in image data to be recorded on a prescribed recording medium. SOLUTION: Image data sent from a digital video cassette recorder(DVCR) 2 are received by a 1394 communication section 11 and outputted to a FIF0 memory 12. When the FIFO memory 12 stores data by one frame, the FIFO memory 12 sets a full flag. Then an integrated drive electronics(IDE) controller 13 reads the data by one frame from the FIFO memory 12 depending on the full flag and converts the data and provides an output of the converted data to a hard disk 3 via an IDE terminal 14. When the data are read from the FIFO memory 12, the full flag is cleared, but since data of a succeeding frame are fed to the FIFO memory 12, the full flag is set again. Thus, the IDE controller 13 processes data of one by one frame corresponding to the flag and provides an output to the hard disk 3.

摘要： PROBLEM TO BE SOLVED: To control first electronic equipment as in the case of second electronic equipment of a different type. SOLUTION: An editing machine 1 outputs a command for controlling a video cassette recorder to a 1394 communication section 31 via an IEEE 1394 bus 11. A system controller 54 converts a command based on the interface of this IEEE 1394 into a command based on an IDE interface to output it to an IDE controller 71. The IDE controller 71 converts data input via a LINK 52 and a FIFO memory 61 into command based on the IDE interface to supply it to an HDD 4 via an IDE interface 12. COPYRIGHT: (C)2007,JPO&INPIT
