    Abstract: Method and apparatus of video coding using decoder derived motion information based on bilateral matching or template matching are disclosed. According to one method, merge index for merge candidate group comprising bilateral matching merge candidate and/or template matching merge candidate are signalled using different codewords. According to another method, the first-stage MV or the first-stage MV pair is used as an only initial MV or MV pair or used as a central MV of search window for second-stage search. According to yet another method, after the reference template for a first reference list is found, the current template is modified for template search in the other reference list. According to yet another method, the sub-PU search is disabled for the template search. According to yet another method, block difference calculation is based on reduced bit depth during MV search associated with the decoder-side MV derivation process.

    Abstract: Method and apparatus of using motion refinement with reduced bandwidth are disclosed. According to one method, a predictor refinement process is applied to generate motion refinement for the current block by searching among multiple motion vector candidates using reference data comprising the target motion-compensated reference block, where if a target motion vector candidate requires target reference data from the target motion-compensated reference block being outside the valid reference block, the target motion vector candidate is excluded from said searching the multiple motion vector candidates or a replacement motion vector candidate closer to a center of the corresponding block of the current block is used as a replacement for the target motion vector candidate. In another method, if a target motion vector candidate belongs to one or more target fractional-pixel locations, a reduced tap-length interpolation filter is applied to the target motion vector candidate.

    Abstract: A method and apparatus for processing of coded video using in-loop processing are disclosed. Input data to the in-loop processing is received and the input data corresponds to reconstructed or reconstructed-and-deblocked coding units of the picture. The input data is divided into multiple filter units and each filter unit includes one or more boundary-aligned reconstructed or reconstructed-and-deblocked coding units. A candidate filter is then selected from a candidate filter set for the in-loop processing. The candidate filter set comprises at least two candidate filters the said in-loop processing corresponding to adaptive loop filter (ALF), adaptive offset (AO), or adaptive clipping (AC). The in-loop processing is then applied to one of the filter units to generate a processed filter unit by using the candidate filter selected to all boundary-aligned reconstructed or reconstructed-and-deblocked coding units in said one of the filter units.

    Abstract: A method and apparatus for loop processing of reconstructed video in an encoder system are disclosed. The loop processing comprises an in-loop filter and one or more adaptive filters. The filter parameters for the adaptive filter are derived from the pre-in-loop video data so that the adaptive filter processing can be applied to the in-loop processed video data without the need of waiting for completion of the in-loop filter processing for a picture or an image unit. In another embodiment, two adaptive filters derive their respective adaptive filter parameters based on the same pre-in-loop video data. In yet another embodiment, a moving window is used for image-unit-based coding system incorporating in-loop filter and one or more adaptive filters. The in-loop filter and the adaptive filter are applied to a moving window of pre-in-loop video data comprising one or more sub-regions from corresponding one or more image units.
