Abstract: An encoding method includes obtaining an image frame to be encoded. The image frame includes one or more image blocks. The method further includes determining one or more complexities of the one or more image blocks. Each of the one or more complexities corresponds to one of the one or more image blocks. The method also includes encoding the one or more image blocks based on the one or more complexities.

Abstract: A video decoder includes a stream dividing circuit configured to divide a stream to obtain a plurality of sub-streams, a processing circuit including a plurality of processing units configured to perform entropy decoding and inverse quantization on the plurality of sub-streams in parallel to obtain inversely quantized data, an inverse transform circuit configured to inversely transform the inversely quantized data to obtain inversely transformed data, and an output circuit configured to output a decoded video according to the inversely transformed data.

Abstract: A multi-channel flow direction controller for a free-flow electrophoresis apparatus, including a base and a propulsion member. The base is provided with a plurality of convex pieces. The propulsion member is provided with a plurality of narrow pieces. The convex pieces and the narrow pieces have the same length and number. One end of the base is provided with a groove, and one end of the propulsion member is disposed in the groove.

Abstract: An exhaust and separation device for a free-flow electrophoresis apparatus, including a buffer reservoir, a buffer pump, a manual inflator, a gas-liquid buffering and separating member, a self-balancing recovery device, and a separation chamber. The separation chamber includes a shell including an upper cover plate, an ion-exchange membrane, and an insulating and thermal conductive base plate. The inlet of the buffer pump is connected to the buffer reservoir via a first connection pipe. The upper surface of the gas-liquid buffering and separating member is provided with an air inlet and a liquid inlet. The lower surface of the gas-liquid buffering and separating member is provided with a plurality of liquid outlets. The separation chamber is provided with buffer inlets and buffer outlets on two ends, respectively. The outlet of the buffer pump is connected to the liquid inlet of the gas-liquid buffering and separating member.
