A method for cyclic code encoding includes: generating, based on a first symbol sequence related to a first part of symbols in the K payload symbols, a first parity sequence corresponding to the first symbol sequence; generating, based on a second symbol sequence related to a second part of symbols in the K payload symbols, a second parity sequence corresponding to the second symbol sequence, where the first part of symbols are different from the second part of symbols; and generating the (N−K) parity symbols based on the first parity sequence and the second parity sequence.

Method and chip for cyclic code encoding, circuit component, and electronic device

Embodiments of this application disclose a synchronization method and a device. A device marks, based on a preset period, a periodic code block in a data bitstream to be sent from a MAC layer to a PHY layer. The device sends the data bitstream to a peer device through the PHY layer, records a sending time of each periodic code block as a first timestamp during sending, and returns the first timestamp to the MAC layer. By marking a timestamp for the periodic code block received from the MAC layer, the device sets a PHY-layer-based time reference scale (namely, the first timestamp) at the PHY layer.

Synchronization method and device

Embodiments of this application disclose methods, systems, and devices for video synthesis. In one aspect, a method comprises obtaining a plurality of frames corresponding to source image information of a first to-be-synthesized video, each frame of the source image information. The method also comprises obtaining a plurality of frames corresponding to target image information of a second to-be-synthesized video. For each frame of the plurality of frames corresponding to the target image information of the second to-be-synthesized video, the method comprises fusing a respective source image from the first to-be-synthesized video, a corresponding source motion key point, and a respective target motion key point corresponding to the frame using a pre-trained video synthesis model, and generating a respective output image in accordance with the fusing. The method further comprises repeating the fusing and the generating steps for the second to-be-synthesized video to produce a synthesized video.
