  • Publication number: 20050273622
    Abstract: A management agent ME1 of a target T1 receives a request of log-in from an initiator of interest and determines whether or not a number of initiators that currently log in the target T1 reaches a predetermined allowable number of simultaneous log-in (steps S210 and S212). In the case of an affirmative answer, the management agent ME1 reads an ordinal number of precedence ā€˜nā€™ allocated to a GUID of the initiator of interest from a queue (step S213) and reads a time constant mapped to the input ordinal number of precedence ā€˜nā€™ from a time constant table (step S214). The management agent ME1 subsequently sends a status packet, which includes a log-in error status and the time constant, to the initiator of interest (step S216). The initiator of interest receives the status packet, reads the time constant included in the input status packet, and outputs another request of log-in to the target T1 at a timing specified by the time constant.

  • Patent number: 6914699
    Abstract: Noise adding unit 700 reads the downloaded target JPEG image from memory and adds designated noise to that JPEG image. Reverse DCT transformation unit 710 performs reverse discrete cosine transformation on the noise-added JPEG image, and transforms it from space frequency to spatial coordinates. Binarization unit 720 binarizes the image that has been expanded to spatial coordinates. This makes it possible to achieve the same processing as half-tone processing on images that have undergone normal orthogonal transformation without putting a large burden on the CPU, etc. and with a small data volume even when transferring via a communication path.

  • Publication number: 20050010562
    Abstract: An annotation database section 232 of a hard disk drive 208 stores annotation data corresponding to each file separately from the file. The annotation data include attribute information, history information, and location information regarding each file. In response to input of desired conditions of an object file to be extracted, a data management module 226 reads out annotation data that meet the input conditions. An annotation information analyzer module 224 analyzes the syntax of the annotation data to gain location information. A data management module 226 obtains the object file from a location identified by the location information. Even when the object file is located at a remote place, for example, in a server on a network, this arrangement enables the object file to be readily extracted. The object file may be an image file or any other file.

  • Publication number: 20030212850
    Abstract: In the case of a series of connectionless transactions starting from a target, a management agent of the target writes an own GUID into a log-in inducement register provided in a common memory via an IEEE1394 bus, so as to induce an initiator to log in. A controller of the initiator checks the log-in inducement register. In the case where the GUID is written in the log-in inducement register, the controller determines that it has received an inducement of log-in and sends a log-in packet to the target with a view to logging in the target. The management agent receives the log-in packet and sends a status packet, which represents a response of accepted log-in, to the initiator. This arrangement of the present invention enables the data transmission starting from the target by the series of connectionless transactions.
