  • Patent number: 9836864
    Abstract: An image processing method includes: computing difference values between a boundary equivalent to an outer edge of a synthesis target region of an Nth frame of a video image, and a boundary equivalent to an outer edge of a synthesis target region of an N?1th frame of the video image; generating a difference image such that whilst pixel values at a boundary of the difference image maintain the difference values, a region inside the boundary of the difference image matches a specific gradient condition; and deriving, an image that is the generated difference image added to the synthesized result image derived for the N?1th frame that is equivalent to a result of synthesizing a synthesis image onto the synthesis target region in the N?1th frame, and substituting the synthesized result image derived for the Nth frame for an image of the synthesis target region in the Nth frame.

  • Patent number: 9083620
    Abstract: As a result of performing a comparing and determining process of determining the relationship among the bandwidth of distributed data in real time in a local group, the incoming data bandwidth to the local group, and the outgoing data bandwidth from the local group, the increase/decrease management and the connection management of each terminal device in the local group are performed. The comparing and determining process compares, for example, a sum of the total sum of the terminal possessed transfer bandwidths and the incoming data bandwidth from other groups to the local group with a sum of the value obtained by multiplying the bandwidth of distributed data in the local group by the number of terminal devices in the local group, the outgoing data bandwidth from the local group, and a predetermined determination margin.

  • Patent number: 8959193
    Abstract: A group management device determines a priority level that represents priority order of allowing a participating terminal to preferentially participate in a group, to which the group management device belongs, based on information relating the participating terminal and information relating to terminals that are managed by the group management device only in a case where the group management device receives information relating to the participating terminal, which has transmitted a participation request to the group, to which the group management device belongs. Based on the determined priority level, the group management device determines whether to transmit the participation request to another group management device and whether to reply to the participating terminal.

  • Patent number: 8239722
    Abstract: In a multicast distribution system in which terminal devices on a distribution path are hierarchically grouped, a first terminal device which has detected a loss of a receiving packet transmits to a second terminal device located upstream of the first terminal device a retransmission request for a packet retransmission to the first terminal device and a third terminal device which receives a packet first in a group located downstream of a group to which the first terminal device belongs. The second terminal device which has received the retransmission request transmits a retransmission packet to both the first and third terminal devices.
