Abstract: Disclosed are method and apparatus for video watermarking, an electronic device and a storage medium. The method includes steps described below. Image data of a target video frame is converted from an RGB format to a YUV format; in the YUV format, an offset with a preset value is superimposed on a pixel value of a pixel point corresponding to a shape be watermarked on the target video frame; and the target video frame on which the offset is superimposed is encoded.

Abstract: A method for image processing is provided.

Abstract: The present invention relates to a method for data transfer between a host and a device as well as to respective apparatus. A host is seen as a communication apparatus which organizes data traffic. A device is seen as dependent on the host. In a tiered-star topology there are usually multiple devices connected to one host. A method for data transfer between a host and a device through pipes is presented. The available memory in the host is divided into multiple segments. The assignment of segments is changed between pipes in dependence on the pipe traffic.
