    摘要： Aspects of the disclosure provide a method and a circuit for adaptive loop filtering in a video coding system. The method can include receiving a block of samples generated from a previous-stage filter circuit in a filter pipeline, the block of samples being one of multiple blocks included in a current picture, performing, in parallel, adaptive loop filter (ALF) processing for multiple target samples in the block of samples, while the previous-stage filter circuit is simultaneously processing another block in the current picture, storing, in a buffer, first samples each having a filter input area defined by a filter shape that includes at least one sample which has not been received, and storing, in the buffer, second samples included in the filter input areas of the first samples.

    摘要： A video processing apparatus includes a first processing circuit, a second processing circuit, and a control circuit. The first processing circuit performs a first processing operation. The second processing circuit performs a second processing operation different from the first processing operation. The control circuit generates at least one output coding unit to the second processing circuit according to an input coding unit generated from the first processing circuit, wherein the control circuit checks a size of the input coding unit to selectively split the input coding unit into a plurality of output coding units.

    摘要： A video decoding apparatus includes a bitstream parser, a calculator and a memory. The bitstream parser is provided to receive a video bitstream and extracting a set of constraints associated with the video bitstream, wherein the set of constraints has information associated with a direct_8×8_inference flag for a macroblock of a picture, wherein the macroblock has N sub-macroblock partitions. The calculator is provided to calculate first motion vector information associated with the macroblock and obtain second motion vector information associated with K of the N sub-macroblock partitions from the first motion vector information according to the information associated with the direct_8×8_inference flag, wherein K is less than N. The memory is provided to store the second motion vector information.

    摘要： A handheld device and a frequency tracking method thereof are provided. The handheld device comprises an oscillator, a radio frequency (RF) chip, a modem module, a first thermal sensor and a thermal module. The oscillator generates an oscillation signal with an oscillation frequency. The RF chip is electrically connected to the oscillator and configured to receive a paging signal from a paging channel and an RF signal from a non-regular channel based on the oscillation signal. The modem module is electrically connected to the RF chip. The first thermal sensor disposed close to the oscillator measures a heat source temperature. The thermal module electrically connected to the modem module and the first thermal sensor enables the modem module to execute a frequency compensation process by using the RF signal of both the paging signal and the RF signal according to the heat source temperature.
