    Abstract: The present invention provides a data transmission apparatus which enhances the safety with respect to leakage of encoded transmitted data by raising the safety of transmission of an encoding key or a decoding key. It provides a large capacity transmission line 152 such as a satellite transmission line for transmitting a large amount of data and a small capacity transmission line 156 such as a public telephone line for transmitting an encoding key or decoding key or information for the generation of them. The encoding session key 107 is generated by using a work key and a destination address of a receiving apparatus of the destination. Further, the decoding session key 108 is generated using one's own address and the work key. The work key is preferably encoded and transmitted through the small capacity transmission line 156. In the transmitting apparatus 101, in addition to the encoding of the data 105 which should be transmitted by using the encoding session converted as described above, transmission control information such as destination data is added and is transmitted to the receiving apparatus 102 through the large capacity transmission line 152. In the receiving apparatus 102, the encoded data 110 is decoded by using the decoding session key 108 converted as described above.

    Abstract: A data transmitter which improves the safety of the transmission using an enciphering key of a decoding key and improves the safety against the leakage of the enciphered transmission data. A large capacity transmission line (152) such as a satellite transmission line through which large capacity data are transmitted and a small capacity transmission line (156) such as a public telephone line which transmits an enciphering key, a decoding key or information for generating these keys are provided. An enciphering session key (107) is generated by using a work key and the address of the receiver on the receiving side. A decoding session key (108) is generated by using the own address and the work key. The work key is, preferably, enciphered and transmitted on the small capacity transmission line (156). In a transmitter (101), not only the data (105) to be transmitted are enciphered by using the enciphering session which is thus converted as described above, but also the transmission control information such as the address data are added to the data (105) and transmitted to a receiver (102) through the large capacity transmission line (152). The enciphered data (110) are decoded by using the decoding session keys (108), which is converted as described above.

    Abstract: PROBLEM TO BE SOLVED: To provide a system wherein one recording apparatus records program contents on behalf of other apparatus without jeopardizing the copyright and the other protections with respect to the contents. SOLUTION: Each apparatus cooperating for a reservation recording function with each other via a network stores the same program as that with reservation recording set thereto on its own apparatus in a form of another file in the case of recording the program on behalf of other apparatus. The AV recording apparatus of the video recording proxy agent encrypts the file for the proxy video recording by using a public encryption key of a video recording requester so that the AV recording apparatus recording the program on behalf of the other apparatus can record the contents but cannot view the contents. Further, the video recording proxy apparatus signs the video recording contents by using a private key of the proxy apparatus to prevent impersonation. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To obtain the format converter with a simple configuration that conducts format conversion processing for plural resources at the same time. SOLUTION: The format converter converts a data format of supplied data of each resource into a packetted data format in the prescribed unit where a serial number is given to each resource. The format converter is provided with a division means 56 that divides sequentially supplied data into plural division data in a prescribed unit and provides an output, count means 61A-61N that count individually and respectively number of division data outputted from the division means for each resource and a packet processing means that adds a count corresponding to the count means to each of division data outputted from the division means as a serial number for each resource, based on the count result of the count means and applies packet processing to the resulting data.

    Abstract: PROBLEM TO BE SOLVED: To attain ease of data delivery with a high transmission efficiency by classifying and storing the result of 1st data of a configuration adding information with respect to a data validity and replacing the stored data with 2nd data according to information of the 2nd data of the same configuration and being delivered. SOLUTION: A data storage section 22 classifies data DT received from a data reception section 21 to a data classification section 222 depending on a header A and a bit B indicating whether or not a validity is provided, prescribed classified data DTa, DTb are stored in a data storage section 223 or outputted to an information discrimination section 224. The information discrimination section 224 discriminates the received data DTb based on a bit C denoting the validity. Then the prescribed discriminated data DTb1, DTb2 are stored in the data storage section 223 or outputted to a data replacement section 225 and replaced with the prescribed data DTb1 stored in the data storage section 223.

    Abstract: PROBLEM TO BE SOLVED: To provide a system for recording video images whose recording capacity is in excess of the simultaneously recordable capability of one recording apparatus. SOLUTION: Many video recording apparatuses are always connected to a broadbanded network and share video recording operations and recording areas with each other by mutually providing inoperative resources by means of cooperation. Each AV recording apparatus ordinarily records video images in its built-in storage device. However, on the occurrence of a video recording request whose recording capacity exceeds the simultaneously recordable capability, the video recording apparatus utilizes the inoperative resources of the other video recording apparatuses cooperated on the network to record the video images on request. Thus, a multi-channel large capacity video recording system can be realized without the need for imposing much load on one video recording apparatus. COPYRIGHT: (C)2005,JPO&NCIPI
