  • Patent number: 9225653
    Abstract: According to one embodiment, a server includes a transmitter, a storage, a determination unit and a controller. The transmitter is configured to transmit data using TCP streams. The storage is configured to store a number of TCP streams which the transmitter used in transmitting the data and a maximum value of a bandwidth which the transmitter used in transmitting the data using the number of TCP streams, in association with each other. The determination unit is configured to determine a number of TCP streams, which the transmitter uses in transmitting new data, based on the stored number, the stored maximum value, and a target value of the bandwidth. The controller is configured to update the stored maximum value when a bandwidth used for transmitting the new data using the determined number is larger than the maximum value associated with the stored number which is identical to the determined number.

  • Publication number: 20150204964
    Abstract: A radio base station performs wireless communication with a wireless terminal. The radio base station includes a directivity pattern specifying unit, a communication unit, and a signal processor. The directivity pattern specifying unit specifies plural directivity patterns. The communication unit receives a search request frame from the wireless terminal, sends to the wireless terminal a search response frame which is a response to the search request frame, with at least one, specified by the directivity pattern specifying unit, of the directivity patterns, and receives a delivery acknowledgment frame for the search response frame from the wireless terminal with the directivity patterns specified by the directivity pattern specifying unit. The signal processor calculates, for each specified directivity pattern, a radio wave intensity of the delivery acknowledgment frame.

  • Patent number: 9065881
    Abstract: According to one embodiment, an image relay apparatus includes a reception unit, a determination unit and a transmission unit. The reception unit receives compressed image data from a relay source apparatus. The determination unit determines whether or not the compressed image data is processable through a first path not involving decompression of the compressed image data, based on data on a relay destination apparatus. The transmission unit transfers, to the relay destination apparatus, either the compressed image data processed through the first path or recompressed image data obtained by processing the compressed image data through a second path involving decompression, drawing, and recompression of the compressed image data.

  • Patent number: 9026584
    Abstract: According to one embodiment, a server device includes a receiver, an acquisition unit, a difference extracting unit, an estimation unit, a determination unit, a compression unit, and a transmitter. The receiver receives manipulation information from a client device. The acquisition unit acquires a display image on which the manipulation information is reflected. The difference extracting unit extracts a region where pixel information on an image transmitted to the client device is not matched with pixel information on the display image. The estimation unit estimates an elapsed time since the manipulation information is received until the display image is acquired. The determination unit determines image quality, for which a response time is a predetermined value or less, on the basis of the elapsed time. The compression unit generates a compression image in which the image in the region is compressed with the determined image quality. The transmitter transmits the compression image.

  • Patent number: 8564819
    Abstract: There are provided an image printing system and an image processing method which can perform printing control for a unit pixel without losing a positional relationship between a dot arrangement pattern and a mask pattern even when index processing and mask processing are executed independently from each other. For this purpose, an index start position command (901) is transmitted, and the mask pattern is arranged such that the top of the mask pattern matches a top raster of a received index processing start position when the mask processing is executed. Thereby, it becomes possible to securely execute the printing control for a unit pixel without losing the positional relationship between the dot arrangement pattern and the mask pattern which are generated in association with each other.
