  • 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: 8615036
    Abstract: In a video signal processing device that generates an interpolated frame between original-image frames formed by an existing video signal, a frame interpolation unit generates pixel interpolation information indicating for each pixel a process in which a pixel forming the interpolated frame is generated. Next, an enhancement-filter-coefficient adjusting unit determines for each pixel a level of enhancement to be applied to the pixel forming the interpolated frame by using pixel interpolation information, and adjusts for each pixel a coefficient of an enhancement filter according to a determined level. An enhancement-filter applying unit then applies the enhancement filter of which coefficient is adjusted for each pixel, to each pixel forming the interpolated frame.

  • Patent number: 8340472
    Abstract: In a pixel interpolation apparatus for interpolating pixels, an edge pixel detection unit detects edge pixels constituting an edge among pixels on lines positioned above/below the interpolation pixel. A continuous edge detection unit detects edge pixels in which two pixels or more consecutively line up among edge pixels detected by the edge pixel detection unit as a continuous edge. A continuous edge pair detection unit determines the combination of the continuous edges detected on each of the lines above and below the interpolation pixel among the continuous edges detected by the continuous edge detection unit. An edge direction determination unit determines the edge direction of the interpolation pixel on the basis of the positional relation of one set of continuous edges determined by the continuous edge pair detection unit. An interpolation pixel calculation unit calculates an interpolation pixel using the edge direction determined by the edge direction determination unit.

  • 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.

  • Patent number: 8159605
    Abstract: A motion vector is searched for each block of the current video frame by using a previous average motion vector within a screen as a reference motion vector, and whether or not interpolation is effective is determined by using the obtained motion vector. If the interpolation is determined to be effective, an interpolation frame is generated between the current video frame and a preceding video frame by using the obtained motion vector.
