Abstract: A hybid resonant DC to DC converter uses an LLC or other resonant structure on the primary side, applying a two state waveform to one end of the resonant structure and a multi-state waveform to the other end of the resonant structure. The waveforms are at or near the resonant resonant frequency and the output voltage level is regulated by varying the shape of the multi-state waveform by varying the duty cycle of the switches used to generate it. The allows the converter to operate near or at its optimal resonant point, resulting in higher efficiency, over a wide range of regulated output voltage levels.

Abstract: A video coding device selects a current block for sub-block based affine inter-prediction, and derives a sub-block size for a sub-block of the current block. The sub-block size includes a sub-block width and a sub-block height. The device determines a unidirectional width threshold (TwU), a bidirectional width threshold (TwB), a unidirectional height threshold (ThU), and a bidirectional height threshold (ThB), where a total value of TwB and ThB exceeds a total value of TwU and ThU.
