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.

A delivery of content to the unspecified number of persons is prevented by limiting the content delivery range. A delivery source terminalgenerates an authentication code based on the number of possible transmission times of content and an authentication code key, and configures the number of possible transmission times and the generated authentication code in a packet. The delivery source terminaltransmits the packet to a delivery destination terminal. A routerverifies whether the authentication code generated based on the number of possible transmission times and the authentication code keythat are received agrees with the authentication code received from the delivery source terminal, updates the number of possible transmission times when the two codes agree, generates a new authentication code, and configures it in the packet. The routertransmits the packet thus generated to the delivery destination terminal

A license servercomprises: a license table for managing licenses purchased by users; a communication control sectionfor transmitting/receiving data through a communications network; an authentication control sectionfor performs authentication processing for a terminal; an encryption/decryption control sectionfor encrypting/decrypting communications with the terminal; an issued temporary license information tablefor storing information on issued temporary licenses; and a return control sectionfor returning a temporary license and then deleting the information on the temporary license stored in the issued temporary license information table

System for managing license for protecting content, server for issuing license for protecting content, and terminal for using content protected by license

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. The first provider ID is compared with the second provider ID when the second provider ID is detected. The digital content is used when the first provider ID and the second provider ID match. The use of the digital content is restricted when the first provider ID and the second provider ID do no match.

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.

Surveillance system

A picture recording method for recording original picture data encodes the original picture so that the entirety of the original picture is displayed at its original resolution on a television monitor after being decoded. The method involves first scaling down an original picture image, then filling top, bottom, and left and right side regions around the scaled down picture image with pixels to attain a picture image that is of the same size and resolution as that of the original picture image. The scaled down and filled in image is then recorded by encoding and storing the picture data at the original resolution. The recorded picture data is then subsequently decoded for displaying all pixels of the original picture image at the original resolution on a television monitor.
