US10708596B2 Forcing real static images
An encoder of a multimedia system encodes data representative of each image in a video stream to form a bitstream that is transmitted over a network to a decoder that decodes the bitstream and provides the decoded information to a multimedia application for display to the user. As consecutive images may have nearly identical pixel values, the multimedia system detects pixel value variations between consecutive images that are below a specified threshold to reduce active processing on such pictures, which includes, for example, encoding, decoding, and post-processing. The multimedia system either selectively encodes or selectively processes the current image that has pixel values that vary from an immediately preceding image within the specified threshold.

US10708592B2 Deblocking filter for video coding and processing
Deblocking is a step in video coding for removing distortions that may result from dividing a video frame into blocks, and encoding the video frame based on the blocks. Techniques described herein can include determining the activity in neighboring blocks along the boundary of the blocks, where the activity measures smoothness or complexity of pixels in the boundary area. An average of the activity can then be determined, as well a difference in the activity between the left block and the right block. The average activity and the difference in activity can then be used to determine a classification for the boundary area. The classification can further be used to select a filter to apply to the pixels in the boundary area. Once the filter have been applied, the blocks can be added to a reconstructed video frame.

The encoding mode for the current block is a partitioning mode for the current block or a coding unit mode for the current block.

Methods, apparatus and software for implementing enhanced data center congestion management for non-TCP traffic. Non-congested transit latencies are determined for transmission of packets or Ethernet frames along paths between source and destination end-end-nodes when congestion along the paths is not present or minimal. Transit latencies are similarly measured along the same source-destination paths during ongoing operations during which traffic congestion may vary. Based on whether a difference between the transit latency for a packet or frame and the non-congested transit latency for the path exceeds a threshold, the path is marked as congested or not congested. A rate at which the non-TCP packets are transmitted along the path is then managed as function of a rate at which the path is marked as congested. In one implementation, non-TCP traffic is managed by mimicking a Data Center TCP technique, under which the congestion marking status of the path is substituted as an input to a DCTP algorithm in place of the normally-used ECN-Echo flag input. The congestion window output by the DCTCP algorithm is then used to manage the rate at which non-TCP packets to be forwarded via the path are transmitted from a source end-node.
