A server provided with: a storage unit for storing reservation information for using a first device that includes information corresponding to the start date/time and end date/time of use of the first device; and a processing unit for transmitting, to a control terminal that controls a second device, a first indication for placing the second device into a prescribed state when the start date/time based on the reservation information stored in the storage unit is reached, and transmitting, to the control terminal, a second indication for placing the second device into a state prior to the start date/time when the end date/time based on the reservation information stored in the storage unit is reached.

Abstract: A remote management server creates a data set-up instruction telegram to be sent to a remotely managed device. A control program extracts the data set-up instruction from the telegram, and outputs same to a communication control bundle. The communication control bundle outputs the data set-up instruction to a basic data management bundle. The basic data management bundle, based on the data set-up instruction, fetches the data to be set in the remotely managed device, and determines whether this data is basic data or extended data. If the data is basic data, the basic data management bundle executes this data set-up process. If the data is extended data, an extended data management bundle executes the data set-up process.

Abstract: A delivery of content to the unspecified number of persons is prevented by limiting the content delivery range. A delivery source terminal 110 generates an authentication code based on the number of possible transmission times of content and an authentication code key 116, and configures the number of possible transmission times and the generated authentication code in a packet. The delivery source terminal 110 transmits the packet to a delivery destination terminal 130. A router 120 verifies whether the authentication code generated based on the number of possible transmission times and the authentication code key 124 that are received agrees with the authentication code received from the delivery source terminal 110, updates the number of possible transmission times when the two codes agree, generates a new authentication code, and configures it in the packet. The router 120 transmits the packet thus generated to the delivery destination terminal 130.

Abstract: When, in a network computer system, a Web browser on a host computer acquires information about images or the like from a network or the like, it analyzes the data received in a proxy server, and, in case the details of the data are moving images, transmits substitute images with the same screen size to host computer, and transmits the moving image access information toward user computer. In case substitute images have been transmitted by proxy server, host computer transmits, to user computer, the display position and screen size of the moving images and information indicating Web server saving the moving images. In this way, it is possible, even when a host computer is remotely operated from a user computer via a network and moving images are displayed, to play back the moving images smoothly.

Abstract: An adaptor connected to a network to conduct encrypted communication includes a storage section for storing connection policy information to determine a communication method between a first communication apparatus and a second communication apparatus, a communication selecting section for determining a communication method using the connection policy information, an encrypted communication section for conducting, if encrypted communication is determined, encryption or decryption of communication data between the communication apparatuses, an external storage medium information reader section for reading information recorded in an external storage medium, and an external information control section for obtaining, if connection of an external storage medium is detected, connection policy information stored in the external storage medium and storing the connection policy information in the storage section.

Abstract: A method for using digital contents is provided. In the method, a request is made to a provider apparatus for a certificate containing a first provider ID embedded therein by a certification authority, and the certificate is received from the provider apparatus. A decision is made by using the certificate as to whether or not the provider is authorized by the certification authority. A request is made to the provider apparatus for a digital content having a second provider ID embedded therein by a contents guarantee authority when the provider is authorized by the certification authority, and the digital content is received from the provider. The first provider ID is read from the certificate, the digital content is correlated with the second provider ID, and the digital content is stored in a storage medium. The second provider ID is detected from the digital content in response to a request to use the digital content.

Abstract: Devices connected to a network are caused to conduct transcoding including combination of various coding schemes. A transcoding system includes (information processing) apparatuses, such as STBs, each including a memory unit and a processing unit, and converts a coding scheme of digital contents. The memory unit stores management information acquired from different apparatuses. The management information concerns conversion functions of coding schemes of digital contents concerning the apparatuses, and is information concerning demultiplexing, decoding, encoding and multiplexing. The processing unit determines different apparatuses capable of transcoding digital contents by referring to the management information, and transfers contents data and information indicating processing contents to the different apparatuses, which includes a format conversion unit to execute transcoding according to processing contents sent from the processing unit in an apparatus.

Abstract: The invention relates to preventing recording from failing because of concentration of recording and recording reservation in a specific device in recording via a network. Concretely, the invention relates to a data recording controller connected to data recording devices provided with a recording medium so that communication is possible. The data recording controller receives input of recording start time and recording termination time of data of broadcast voice and images, receives a maximum simultaneous recording number which can be simultaneously written to each recording medium, receives a simultaneous recording reserved number which are scheduled to be written to each recording medium from the recording start time to the recording termination time and stores a data recording device where the simultaneous recording reserved number is smaller than the maximum simultaneous recording number.

Abstract: A surveillance image is acquired from a surveillance camera. Supplement information (such as date and time, and surveillance camera number) relating to the surveillance image is acquired. By imaging the supplement information, supplement information image data is generated. A quantized discrete cosine transform coefficient block obtained by conducting discrete cosine transform and then quantization on surveillance image data of the surveillance image is added to a quantized discrete cosine transform coefficient block obtained by conducting discrete cosine transform and then quantization on the supplement information image data. A resultant sum is subjected to Huffman encoding. The result is recorded.
