Abstract: An on-board charging (OBC) device for an electric vehicle includes a mains input including a power factor correction (PFC) converter, a mains-side direct current-to-alternating current (DC/AC) converter, a transformer having a mains-side coil and a battery-side coil, a battery-side alternating current-to-direct current (AC/DC) converter, a battery connector and one or more bypass switches configured to galvanically connecting the mains-side converter to the battery-side converter when closed. The transformer is configured to be magnetically coupled to a transmitter (TX) pad of an external wireless power transmitter (WPT), such that power is received by the mains-side coil and the battery side coil. When the bypass switches are closed, and the transformer is magnetically coupled to a WPT, power is sent to the battery connector through both the battery-side converter and the mains-side converter.

Abstract: This application provides a communication method and apparatus. In the method, a first device determines a first quality of service parameter corresponding to a non-uncrewed aerial vehicle service of a terminal device, and sends the first quality of service parameter to a second device. The first quality of service parameter includes one or more of the following parameters: a first maximum bit rate corresponding to the non-uncrewed aerial vehicle service; a first priority indicating that a priority of a data flow of the non-uncrewed aerial vehicle service is lower than a priority of a data flow of an uncrewed aerial vehicle service; or a first identifier indicating a data flow of the non-uncrewed aerial vehicle service.

Abstract: An apparatus for embedding a message bit sequence in a video stream is disclosed. The apparatus is configured to determine one or more transformation frames of the at least one frame of the plurality of frames of the video stream based on a wavelet kernel filter. Moreover, the apparatus is configured to encode the message bit sequence by performing for each bit of the message bit sequence a pointwise multiplication of absolute values of the elements of subframes of the one or more transformation frames, depending on the value of the respective message bit of the message bit sequence, with the elements of a first encoding matrix or the elements of a second encoding matrix for obtaining one or more modified transformation frames.

Abstract: The present disclosure relates to picture encoding and decoding of image regions on tile-basis. In particular, multiple components of an input tensor including a first and second component in spatial dimensions is processed within multiple pipelines. The processing of the first component includes dividing the first component in the spatial dimensions into a first plurality of tiles. Likewise, the processing of the second component includes dividing the second component in the spatial dimensions into a second plurality of tiles. The respective first and second plurality of tiles are then processed each separately. Among the first and second plurality of tiles there are at least two respective collocated tiles differing in size. In case of compression, the processing of the first and/or second component includes picture encoding, rate distortion optimization quantization, and picture filtering. In case of decompression, the processing includes picture decoding and picture filtering.

Abstract: A coding method for data communication is provided, and may be applied to a plurality of scenarios such as a metro network, a backbone network, and a data center interconnection. The method includes: forming a first codeword, where the first codeword includes n image bits and n to-be-transmitted bits, the n image bits are selected from to-be-transmitted bits in m source codewords, the source codeword is a codeword formed before the first codeword, both n and m are positive integers, and n>m; and sending the n to-be-transmitted bits in the first codeword. The bit in the first codeword is protected by a plurality of codewords generated at different moments, and a coding gain effect is better. In addition, the bit in the codeword is protected by different quantities of codewords.
