摘要： A method for correcting artifacts in compressed video having interlaced frames may comprise receiving decoded video data, the decoded video data including a frame and metadata corresponding to the frame. The method may further comprise applying a vertical chroma filter to the frame responsive to determining that the metadata indicates that the frame is an interlaced frame.

摘要： A host has a graphics pipeline that process frames by portions (e.g., pixels or rows) or slices. A remote device transmits a video stream container via a network to the host. A frame of the video stream in the container has encoded portions. The graphics pipeline includes a demultiplexer that extracts the portions of the video frame. When a portion has been extracted it is passed to a decoder, which is next in the pipeline. The decoder may begin decoding the portion before receiving a next portion of the frame, possibly while the demultiplexer is demultiplexing the next portion of the frame. A decoded portion of the frame is passed to a renderer which accumulates the portions of the frame and renders the frame. At any time portions of a frame might concurrently be being received, demultiplexed, decoded, and rendered. The decoder may be single-threaded, multi-threaded, or hardware accelerated.

摘要： An adaptive video noise reduction (AVNR) engine reduces noise in streaming video. The engine reads embedded information in the streaming video describing attributes of the video, such as bit rate, frame rate, resolution, content type and quality of the streaming video. The information may be included in a manifest of the streaming video. Based on the video attributes, the engine outputs one or more input values to applications that reduce noise of the streaming video. The one or more applications may reduce mosquito, block, temporal, random and banding noise of the video in response to the input values from the engine.
