Abstract: The invention provides computer-readable media (CRM) configured to adapt a text-to-image (T2I) diffusion model for video editing by using spectral decomposition to achieve controlled spectral shifts in the model's weights. This CRM maintains constant singular vectors while selectively adjusting singular values according to a text prompt. A spectral shift regularizer constrains these adjustments, particularly limiting changes to larger singular values to ensure minimal deviation from the original model's structure. This approach enables efficient, prompt-driven video editing by modifying specific visual elements according to the prompt while preserving original video context. By employing selective spectral adjustments, the CRM significantly reduces adaptation time and computational demands, making it suitable for real-time, resource-sensitive applications such as dynamic video editing in streaming services.

Abstract: A power converter and a data collector. A power line communication (PLC) chip in the power converter can transmit a data signal on a first frequency band, and transmit a control signal on a second frequency band. Signals of different types can be transmitted on the first frequency band and the second frequency band, and the first frequency band and the second frequency band do not overlap each other. Therefore, interference between the signals of different types can be effectively avoided, and simultaneous transmission of the signals of different types can be implemented. This not only effectively enhances flexibility of signal transmission, but also effectively avoids a transmission delay caused by a transmission conflict between the signals of different types in the PLC system, ensuring high timeliness for the data collector to perform data query and scheduling control on the power converter.
