    摘要： A method and apparatus of encoding frames with a frame type structure adaptively according to a current encoding status after receiving a request for an IDR frame or receiving an indication of picture data loss are disclosed. If the check result of the current encoding status is true, the second frame type structure is the same as the first frame type structure; and if the check result of the current encoding status is false, the second frame type structure is different from the first frame type structure. Another method and apparatus of encoding frames with a reference frame structure and a frame type structure adaptively according to one or more current encoding statuses after receiving an indication of picture data loss are disclosed. The system may use two different check results to adaptively select the reference frame structure and the frame type structure.

    摘要： An image processing method includes at least following steps: partitioning a picture into a plurality of picture regions, wherein each picture region comprises at least one pixel group row, each pixel group row comprises at least one pixel group, and the picture regions comprise a first picture region and a second picture region horizontally adjacent to each other; and performing flatness check upon a specific pixel group in a pixel group row of the first picture region through using at least one pixel borrowed from the second picture region.

    摘要： In order to overcome the issue caused by a decoded block vector (BV) pointing to a reference block overlapping with an unavailable area, various methods are disclosed. According to one method, if the reference block overlaps with an unavailable area, the reference pixels in the unavailable area are generated for IntraBC prediction of the current block by padding from neighbouring available pixels. The padding can be done in the horizontal direction and then the vertical direction. The padding may also done in the vertical direction first and then horizontal direction. In another method, if the reference block overlaps with an unavailable area, the reference pixels in the unavailable area are generated for IntraBC prediction of the current block by using previous decoded pixels in the unavailable area. A pre-defined value may also be used for the unavailable area.

    摘要： Method and apparatus of video coding using coding modes including Intra Block Copy (IntraBC) for a video coding system incorporating multi-stage pipeline processing is disclosed. In order to overcome data dependency issue due to the use of pipeline architecture, a first embodiment uses constrained previous reconstructed region for IntraBC estimation by excluding unavailable reconstructed previous reconstructed data due to the multi-stage pipeline processing. In the second embodiment, the unavailable reconstructed data is replaced by source pixel data.
