摘要： Each of the plurality of queues stores packet data of a received packet. The read concession assignor assigns one of the plurality of queues with a read concession for a predefined time period. The overdraft storage stores an overdraft amount in connection with each of the plurality of queues. The read adequacy determiner determines, in accordance with an overdraft amount stored in connection with one queue out of the plurality of queues, whether to read packet data from the one queue. The overdraft updater updates at least one of a first overdraft amount stored in connection with a first queue and a second overdraft amount stored in connection with a second queue different from the first queue upon reading packet data from the first queue during a time period while the second queue is assigned with the read concession.

摘要： A buffer operation method, for use with a buffer organized as a plurality of sections, two or more continuous ones of the sections being defined as a monitor block, the method including: receiving a data packet and dividing the same into a plurality of divisions; storing the divisions in a given one of the sections; moving, in the case where the given section is behind the monitor block, the monitor block so that a tail end thereof corresponds to the given section; monitoring whether the plurality of divisions required for reassembly of the packet are stored in the monitor block; and transferring, once all the required plurality of divisions are collected in the monitor block, the same from the buffer for subsequent reassembly of the packet.

摘要： An image interpolation device (310) includes a feature quantity calculating unit (313), an image interpolation processing unit (314), a resolution conversion processing unit (315) and a display control processing unit (316). With regards to pixels positioned in an interpolation subject area and peripheral pixels of the pixels, the feature quantity calculating unit (313) calculates feature quantities of the pixels. The image interpolation processing unit (314) extracts a pixel with the largest feature quantity from among the pixels positioned in the interpolation subject area. When the feature quantity of the extracted pixel is equal to a threshold or more, the image interpolation processing unit (314) sets a pixel value of the pixel as a pixel value of interpolation pixels. The resolution conversion processing unit (315) performs a resolution conversion on image data of which the interpolation pixels have been interpolated by the image interpolation processing unit (314). The display control processing unit (316) performs control to realign a plurality of pieces of image data including at least one piece of image data to which the resolution conversion has been performed by the resolution conversion processing unit (315) to a predetermined display configuration and display the realigned data.

摘要： A packet transmission apparatus includes a transmission unit dividing input data and transferring segments, which are obtained by adding sequence numbers to the respective pieces of the divided data, a switch unit transferring the segments to one of a plurality of reception units, and a reception unit reconstructing an original input packet from the plurality of segments that arrive from the switch units on the basis of the sequence numbers. The reception unit includes a packet buffer storing segments that arrive from the switch units, a determination unit determining, on the basis of the sequence number, whether the segment stored in the packet buffer is to be discarded; and a discard part reading the segment stored in the packet buffer in an order from the segment having an older sequence number and discarding the segment that is determined to be discarded.
