  • Patent number: 10104400
    Abstract: A video encoding and decoding method, device and system is disclosed, wherein the method includes: after using a standard encoding algorithm to complete encoding a luminance component in a current image, judging, based on refreshing images preset by an encoding device, whether there is a need to encode a chrominance component in the current image in accordance with the standard encoding algorithm or not, and encoding the corresponding chrominance component in accordance with the standard encoding algorithm if the current image is any one of the refreshing images preset by the encoding device, otherwise, not encoding the corresponding chrominance component in accordance with the standard encoding algorithm, wherein an encoding reconstruction of the chrominance component is obtained by copying a corresponding chrominance component in a reference image of luminance component, so that a finally output code stream does not comprise information of the corresponding chrominance component.

  • Publication number: 20170101122
    Abstract: a foldable stroller capable of being formed into a trolley, comprising a front tube, a rear tube, a seat frame, an armrest, a pushing lever, and a handle connected to the pushing lever via a second joint assembly which allows pivotal movement of the handle relative to the pushing lever; the front tube having an extensible draw bar; wherein when the rear tube, seat frame, armrest and pushing lever are folded toward the front tube by joints, the handle is pivotally moved at 90-100 degrees relative to the pushing lever through the second joint assembly, and then the draw bar is pulled out of the front tube, whereby the trolley is formed; the foldable stroller can be folded in a small size and is easy to carry and store, moreover, if the baby has grown up, the stroller can be used as the trolley to avoid unnecessary waste.
