The present invention relates to a displaying method for video image coded data which prevents deterioration of image quality of a video image as much as possible, and conceals, from an observer, deteriorated video quality caused due to a transmission error. The displaying method selects target image frames to be decoded and target image frames to be discarded, by performing error determination () in parallel with an error recovery process and other image restoration processes, and decodes () only the selected target image frames. A predetermined display device sequentially displays () only the decoded target image frames while adjusting a frame rate.

Video image coded data display method, device, and communications system

The present invention relates to a moving-picture image data-distribution method that suppresses increases in processing loads at respective information terminals without being affected by an uneven distribution status of processing loads that changes over time or by a bandwidth status of a connected network. During a distribution operation of moving-picture image data from transmission-side information terminals () to a reception-side information terminal (), when the reception-side information terminal () repetitively issues a transmission requirement for moving-picture image data at a predetermined time interval to the transmission-side information terminals (), the reception-side information terminal () calculates, in advance, at least any one data amount of an own receivable amount of image frames and an own permissible load amount as reception-limit information, and subsequently sequentially notifies the transmission-side information terminals () of an upper limit of at least any one of the data amount and a data structural element that is used as a basis for calculation of the data amount.

Moving-picture image data-distribution method

The present invention relates to a traffic control apparatus and the like for optimizing a communication performance of each of local networks to be monitored. The traffic control apparatus () temporarily stores in the memory () communication band information items of relay nodes (B,B,B) through the I/O (). The controller () specifies a bottleneck relay node based on the obtained communication band information items, calculates transmittable/receivable bands to be allocated to the PCs (B), and notifies the PCs (B) of the calculated transmittable/receivable bands. In response to this notification, the PCs (B) divide data to be transmitted, with the divided data corresponding to the allocated bands, and transmit the divided data to the Internet (), in a manner that the divided data are arranged temporally evenly.

A master key (K) inputted by an input unit is stored in a storage unit. A matrix generating unit generates key element matrices (M-M) with respect to each of split keys (e, e, e) obtained by a key dividing unit dividing the master key (K). To each coordinate entry of the key element matrices (M-M), operation data that successively obtained by repeating a hash operation with a one-way hash function is assigned, so as to maintain hierarchical nature of scalability (L). A key generating unit generates partial keys (K-K) corresponding to respective hierarchies of the scalabilities (R, L), on the basis of the key element matrices (M-M). These partial keys (K-K) are outputted to a coding unit or a decoding unit by an output unit.

Encryption key generation device

The present invention relates to an image processing method and image inspecting method with high versatility which enable efficient and highly accurate proof of authenticity of a digital image. The image processing method subjects at least a part of a digital image which can exist temporarily or continuously in a falsification-vulnerable environment, to a first morphology operation using a predetermined structuring element, to process the digital image. The image inspecting method subjects the digital image thus processed, to a second morphology operation using the same structuring element as in the first morphology operation. The morphology operations have the idempotent and the presence or absence of falsification can be detected by determining identity of images before and after the second morphology operation.

Image processing method and image inspecting method

A computer apparatus has a type data storing part which stores type data regarding file types set according to models of image forming devices and a data file storing part which stores data files of described file types acquired from the image forming devices. The apparatus receives a selection of the models of The image forming devices with the data files acquired thereby and the data files stored in the data file storing part, and selections of the model of the image forming device outputting the data files, the file types different from the described file types and storage destinations of the data files. When receiving an instruction for a conversion, the apparatus converts the data files stored in the data file storing part into file types different from the described file types and stores them in the storage destinations of the data files.

Computer apparatus

There is provided a service control system including a service side system and a customer side system including a service target machine, and the service side system includes a service client terminal which converts set data relative to the service target machine into XML data and edits it and a mail server which transmits to the customer side system an email concerning service setting including the set data, and remotely manages the service target machine by including a predetermined command in the email concerning the service setting.
