Abstract: Innovations in the area of prediction of block vector (“By”) values improve encoding or decoding of blocks using intra block copy (“BC”) prediction. For example, some of the innovations relate to use of a default BV predictor with a non-zero value. Other innovations relate to use of a selected one of multiple BV predictor candidates for a current block. Still other innovations relate to use of a skip mode in which a current intra-BC-predicted block uses a predicted BV value.

Abstract: A set of primers and probes for simultaneous detection of Cymbidium mosaic virus (CymMV), Odontoglossum ringspot virus (ORSV), and Cymbidium ringspot virus (CymRSV) and a method for detecting CymMV, ORSV, and CymRSV, along with a method for their detection, are disclosed. The method involves designing multiplex real-time quantitative PCR detection primers and probes for CymMV, ORSV, and CymRSV and applying these primers and probes to the real-time quantitative PCR simultaneous detection of CymMV, ORSV, and CymRSV. It allows for faster detection of CymMV, ORSV, and CymRSV, taking only one-third of the time compared to uniplex real-time quantitative PCR technology, thereby reducing testing costs by approximately ? to ½ for each sample. The primers and probes are highly specific and sensitive, with a sensitivity as low as 1 to 10 copies. It provides an efficient and feasible detection method for early detection and prevention of CymMV, ORSV, and CymRSV.

Abstract: A method includes dividing a backlight source and a liquid crystal panel into N row sections, preprocessing 3D images to output first images and second images of left and right eyes in a complementary format, while preserving odd and even row section images of original images of the left and right eyes, and sequentially scanning the first images and second images of the left and right eyes from top to bottom using the backlight source. The method further includes, after scanning a row section, controlling the backlight of the row section to be turned on and then turned off until the same row section of a next image starts to be scanned, and repeating until all images are scanned. The method thus provides a crosstalk-free 3D effect and reduces power consumption of the backlight source.
