Abstract
Video decoding systems and techniques are described. A decoder reads first video data from a first block of a video frame. The decoder retrieves neighboring video data from a line buffer. The neighboring video data is from a neighboring block that neighbors the first block in the video frame. The decoder processes the first video data and the retrieved neighboring video data using a constrained directional enhancement filter (CDEF) to generate filtered first video data. The decoder upscales the filtered first video data using an upscaler to generate upscaled filtered first video data. The decoder upscales the retrieved neighboring video data using the upscaler to generate upscaled neighboring video data, for instance after generating the filtered first video data. The decoder processes the upscaled filtered first video data and the upscaled neighboring video data using a loop restoration (LR) filter to generate output video data.
