  • Publication number: 20230283804
    Abstract: A non-transitory computer-readable recording medium storing a transmission program causing a computer of a first transmission apparatus to execute a procedure, the procedure includes detecting a collision between a transmission timing of an intra-coded video frame in first video data transmitted from the first transmission apparatus and a transmission timing of an intra-coded video frame in second video data transmitted from a second transmission apparatus, changing, when the collision is detected at a first time, a frame type of the first video data to one of a forward predictive coded video frame and a bi-directional predictive coded video frame, and transmitting the first video data of which the frame type is changed, at a second time at which the intra-coded video frame in the first video data is scheduled to be transmitted.

  • Patent number: 11273217
    Abstract: Mesothelioma growth inhibitory effect of standard cisplatin-pemetrexed concomitant therapy is potentiated by combination with an anti-CD26 antibody. A high therapeutic effect and excellent safety is obtained by the concomitant use of an anti-CD26 antibody and gemcitabine. By conjugating an anti-CD26 antibody (YS110) with triptolide via a divalent cross-linking agent for concomitant therapy using the anti-CD26 antibody, a novel antibody-drug conjugate (Y-TR1) very highly effective for CD26-positive malignant mesothelioma cells has been successfully obtained.

  • Patent number: 10250891
    Abstract: A storage circuit stores a decoded image of a coded image that is coded before a coding target image included in a video to which the still-image coding and the video coding are applied. A video coding circuit codes the coding target image by inter prediction coding that uses the decoded image as a reference image when the still-image coding is applied to the mage that is one image previous to the coding target image and the video coding is applied to the coding target image.

  • Publication number: 20170264913
    Abstract: A processor requests a first stream encoded by irreversible encoding from an encoding device, decodes the first stream, generates a first decoded image from a first encoded image obtained by encoding one image, and outputs the first decoded image. Then, the processor requests a second stream from the encoding device. The second stream includes a second encoded image obtained by applying inter-prediction to the one image and by encoding a prediction error by reversible encoding, the inter-prediction using a locally decoded image obtained by decoding the first encoded image as a reference image and using a motion vector for which a magnitude is 0. The processor decodes the second stream, generates a second decoded image from the second encoded image, generates a third decoded image that corresponds to the first decoded image by using a result of adding the first and second decoded images, and outputs the third decoded image.
