Abstract: A mechanism of video coding is provided. The mechanism includes generating a reconstructed image from an encoded video stream. The reconstructed image is filtered to create a filtered image. The filtering includes applying a noise suppression filter to the reconstructed image. The noise suppression filter may be applied immediately prior to applying a deblocking filter to the reconstructed image, between a deblocking filter and a sample adaptive offset (SAO) filter, between the SAO filter and an adaptive loop filter, or after the adaptive loop filter. The filtered image is then stored in a picture buffer in memory for use in encoding or for output to a display in decoding.

Abstract: A method of coding implemented by a decoding device. The method includes receiving a bitstream containing a picture from an encoding device, dividing the picture into coding tree units (CTUs), partitioning one of the CTUs into first sub-blocks using quad-tree (QT) partitioning, and partitioning the first sub-blocks into second sub-blocks using a first type of partitioning (e.g., BT or TT). Thereafter, partitioning of the second sub-blocks is restricted to only the first type of partitioning. An image generated using the one of the CTUs as partitioned is displayed on a display of an electronic device.
