  • Publication number: 20090244392
    Abstract: A first buffer analyzer receives attribute information (a) of a video signal (A) from a stream buffer (A) to determine an encoded picture type after correction and a generated encoding amount after correction for a switch terminating measure. A second buffer analyzer receives attribute information (b) of a video signal (B) and final buffer-state information after the switch terminating measure from a stream buffer (B) to determine an encoded picture type after correction and a generated encoding amount after correction for a switch starting measure. A re-encoder/re-quantizer (A) and a re-encoder/re-quantizer (B) perform the switch terminating measure and the switch starting measure on the video signals (A) and (B), respectively, based on the correction information from the first and second buffer analyzers.

  • Patent number: 7569373
    Abstract: A method for counting megakaryocytes in a specimen is described. In the method, first, erythrocytes in the specimen are lysed and nucleic acid in the megakaryocytes is stained with a fluorescent dye, and thereby, a measurement sample is prepared. Next, the cells in the measurement sample are irradiated with excited light so that the forward scattered light, the side scattered light and the fluorescence, which are emitted from the cells, are detected. Megakaryocytes are identified on the basis of the detected forward scattered light, the fluorescence and the side scattered light. Then, the identified megakaryocytes are counted.

  • Publication number: 20090089640
    Abstract: A retransmission apparatus retransmits TS (Transport Stream) packets based on a received broadcast wave to a plurality of receiving apparatus through a network. The retransmission apparatus has a TS packet determination unit for determining whether a continuity of circulation counter values in the TS packets keeps in length equal to or more larger than a first predetermined threshold value N, and for retransmitting these TS packets when the determination is true, or for canceling these TS packets when the determination is false. Also, the TS packet determination unit determines whether a discontinuity of circulation counter values in the TS packets keeps in length equal to or more larger than a second predetermined threshold value T without retransmitting these TS packets, and sends an “off service” signal to a plurality of receiving apparatus when the determination is true.
