摘要:
Viewer individual attribute information indicating an attribute of a particular viewer such as an age, male or female, a resident district, a taste, an occupation and a life style is stored in a receiving terminal apparatus of the particular viewer. When a broadcasting program is transmitted from a service supply apparatus to the receiving terminal apparatus, service addition information indicating an attribute of the broadcasting program or an attribute condition required of viewers is transmitted to the receiving terminal apparatus with contents of the broadcasting program. In the receiving terminal apparatus, the service addition information is collated with the viewer individual attribute information of the particular viewer, and it is judged whether or not the broadcasting program is suitable for the particular viewer. In cases where the broadcasting program is suitable for the particular viewer, the broadcasting program is received by the receiving terminal apparatus and is reproduced and displayed. Therefore, the broadcasting program can be received by only a group of particular viewers desired on a side of the service supply apparatus even though the group of particular viewers is not specified.
摘要:
A system capable of storing the application packages and thereafter reproducing a desired one of the stored application packages at any time. The application package comprises a plurality of applications. Each of the applications comprises application data which comprises forms a main body of the application and service adding information (SAI) comprising various data including an application ID of the application. The SAIs are distributed independently from and prior to the application data. Each of the SAIs can include method IDs of methods for processing object data specified by a method processing program and a plurality of link data comprising application IDs of other applications. This permits the SAIs to form a tree structure of the applications. The methods are activated in a event driven manner.
摘要:
Disclosed is a means for improving the poor conversion efficiency in a conventional bioconversion system using a transformant which is given by introducing a gene originated from xerogenic organisms. A transformant is prepared by using a host which is defective in a gene encoding a multidrug efflux protein and introducing a gene originated from xerogenic organisms. Use of the transformant results in much effective microbial conversion of a hydrophobic or amphipathic substrate compound into a desired compound. In case, an Escherichia coli is used as the host, the gene encoding a multidrug efflux protein to be defective may be tolC, acrA, acrB and the like.

Disclosed is a means for improving the poor conversion efficiency in a bioconversion system using an Escherichia coli cell having a bacterium-originated cytochrome P-450 gene integrated therein. A recombinant Escherichia coli cell is produced by introducing aciB and aciC which encode a gene for the electron transport system originated from the Acinetobacter sp. OC4 strain into an Escherichia coli cell, and adding a polynucleotide encoding an N-terminal sequence composed of 48 amino acid residues of AciA and the like to the 5′-terminus of a bacterium-originated cytochrome P-450 gene, wherein AciA is an alkane-oxidative cytochrome P-450 originated from the Acinetobacter sp. OC4 strain. Use of the recombinant Escherichia coli cell results in much effective microbial conversion of a hydrophobic or amphipathic substrate compound into a desired compound.
摘要:
In a pay broadcasting system, data of a broadcast program is scrambled with a scramble key updated in a short period. The scramble key is encrypted with a first key assigned to the subscriber terminal. The first key is encrypted with a first master key set in the subscriber terminal. The security of a broadcast program stored for subsequent use in the subscriber terminal is enhanced as follows. A central station generates a second key-encrypted scramble key by encrypting the scramble key with a second key different from the first key and changeable in an interval shorter than a update interval of the first key; generates an encrypted second key by encrypting the second key with a second master key which has been commonly issued to subscriber terminals of the system; and broadcast the second key-encrypted scramble key and the encrypted second key together with the scrambled data of the program, the first key-encrypted scramble key and the encrypted first key in a multiplexed manner. When a broadcast program is to be stored, the subscriber terminal stores the scrambled data of the broadcast program and the second key-encrypted scramble key; decrypt the encrypted second key with the second master key into the second key, which is added to a stored program second key list. If the stored program is to be executed, the second key-encrypted scramble key is decrypted with a corresponding one of the second keys in the stored program second key list into a decrypted scramble key; and the scrambled data of the broadcast program is unscrambled with the decrypted scramble key.
