  • Publication number: 20240345974
    Abstract: An electronic device for performing communication with a master device via a serial communications bus and a method for performing assignment of an identifier on the electronic device are provided, wherein the master device is coupled to multiple slave devices via the serial communications bus, and the multiple slave devices include the electronic device. The electronic device includes a clock terminal, a data terminal, and a determination circuit coupled to the clock terminal and the data terminal, wherein the clock terminal and the data terminal receive a first signal and a second signal from the master device, respectively. The determination circuit determines whether a time point of pulling down the first signal is earlier than a time point of pulling down the second signal, in order to generate a determination result, wherein the assignment of the identifier of the electronic device is controlled according to the determination result.

  • Patent number: 11882277
    Abstract: A video encoding method includes: during a first period, performing an encoding process upon a first block group of a current frame to generate a first block group bitstream; and during a second period, transmitting a second block group bitstream derived from encoding a second block group of the current frame, wherein the second period overlaps the first period. The encoding process includes: during a first time segment of the first period, performing a first in-loop filtering process upon a first group of pixels; and during a second time segment of the first period, performing a second in-loop filtering process upon a second group of pixels, wherein the second time segment overlaps the first time segment, and a non-zero pixel distance exists between a first edge pixel of the first group of pixels and a second edge pixel of the second group of pixels in a filter direction.
