This disclosure provides a cross-channel distributed video encoding and decoding method and system based on multidimensional attention, which can be applied to the field of video encoding and decoding technology. The method includes: acquiring a group of video images to be transmitted, the group of video images including a first key reference frame, a second key reference frame, and at least one intermediate video frame; encoding the first key reference frame and the second key reference frame into first encoded data and second encoded data, respectively; encoding each intermediate video frame into third encoded data based on a frame encoder; extracting multi-scale features from each third encoded data based on a multidimensional attention mechanism; processing the multi-scale features into fourth encoded data based on a multi-channel feature extraction mechanism; processing at least one fourth encoded data into a first bitstream; and converting the first encoded data and the second encoded data into a second bitstream, so as to transmit the video image group to the decoder via the first bitstream and the second bitstream.

The utility model relates to the technical field of sample classification, in particular to a food sampling inspection sample classification coding device which comprises a storage box, a plurality of ejection mechanisms are connected to the bottom of the inner wall of the storage box, vertical grooves and inserting grooves are formed in the two sides of the storage box, moving mechanisms are arranged in the two vertical grooves, and the moving mechanisms are arranged in the inserting grooves. A storage frame is connected between the two moving mechanisms, the multiple ejection mechanisms all extend into the storage frame, and locking mechanisms are arranged on the two moving mechanisms. A plurality of sampling tubes embedded in the storage frame can be easily ejected out from the corresponding transparent plates by a worker, so that the worker can conveniently take the collected sampling tubes and clearly know the serial number of each sampling tube, samples are classified, and meanwhile, the sampling efficiency is improved. And the convenience of taking out the plurality of sampling tubes is also improved.

This utility model provides a low-noise mahjong machine, belonging to the technical field of mahjong machine technology; it includes a mahjong table, with a shuffling assembly rotatably connected to the bottom of the inner cavity of the mahjong table, a base fixedly connected to the bottom of the mahjong table, a No. 1 motor fixedly connected to one end of the inner side of the base, and a drive gear fixedly connected to the output end of the No. 1 motor. The drive gear meshes with the bottom end of the shuffling assembly. Inner grooves are formed around the inside of the mahjong table, and a cleaning assembly is rotatably connected to the inner side of each inner groove. This utility model, by setting up the cleaning assembly, allows a bidirectional screw to drive the inner screw sleeves on both sides, and pushes the surrounding push plates inward through a transmission rod. This allows the push plates to push the mahjong tiles above the table into the mahjong table, eliminating the need for manual pushing and improving the automation performance of the mahjong machine. Furthermore, the side grooves on the outer sides of adjacent push plates prevent collisions between the four push plates, facilitating the operation of the cleaning assembly.
