Abstract: Methods and apparatus for loop-filter processing of reconstructed video are disclosed. According to one method, multiple CC-ALF (Cross-Component Adaptive Loop Filter) filters are used. Selection of the multiple CC-ALF filters can be signalled in one APS (Adaptation Parameter Set). According to another method, the CC-ALF can be implemented according to the difference between a to-be-process sample and its neighbouring sample.

Abstract: A package structure is disclosed. The package structure includes a first substrate, a second substrate, a gap, and a directing structure. The second substrate is disposed under the first substrate. The gap is between the first substrate and the second substrate. The gap includes a first region and a second region. The first region is configured to accommodate a filling material. The directing structure is disposed in a flow path of the filling material and configured to reduce a migration of the filling material from the first region to the second region.

Abstract: A synchronization rectification device is connected with a secondary side of a transformer of a power supply and an output capacitor. The synchronization rectification device includes a rectification switch, a voltage-controlled switch module and a rectification controller. The rectification switch is connected between the secondary side and the output capacitor. The voltage-controlled switch module connected with the secondary side has a voltage-division capacitor and receives a secondary voltage generated by the secondary side. The rectification controller is connected with the rectification switch and the voltage-controlled switch module. When the secondary voltage rises to a switching voltage value below a first voltage value, the rectification controller controls the rectification switch to be turned off. After the rectification switch is turned off, the voltage-controlled switch module is turned off, and the voltage-division capacitor receives the secondary voltage.
