  • Patent number: 12273542
    Abstract: Media content may be mastered at a higher quality than is supported on various remote workstations to perform tasks with respect to that content, using transmission channels that do not support data transfer rates for large, high quality media content. A compressed version of this content may be transmitted over a first channel for use with various tasks on a remote workstation. For tasks such as color grading that benefit from this higher quality content, a separate but parallel communication channel is used to transmit a higher-quality version of this content. An uncompressed video stream can be encoded using a lossless codec to retain higher quality data. A high quality video stream can be transmitted over a separate transmission channel, and received to a decoder that can decode this stream to provide a high quality video signal for presentation via a grading monitor or other such high quality presentation device.

  • Patent number: 12192454
    Abstract: Offset values, such as Sample Adaptive Offset (SAO) values in video coding standards such as the High Efficiency Video Coding standard (HEVC), may be improved by performing calculations and operations that improve the preciseness of these values without materially affecting the signal overhead needed to transmit the more precise values. Such calculations and operations may include applying a quantization factor to a video sample and at least some of its neighbors, comparing the quantized values, and classifying the video sample as a minimum, maximum, or one of various types of edges based on the comparison. Other sample range, offset mode, and/or offset precision parameters may be calculated and transmitted with metadata to improve the precision of offset values.

  • Patent number: 12184840
    Abstract: This invention predicts that intra mode prediction is more effective for the macroblocks where motion estimation in inter mode prediction fails. This failure is indicated by a large value of the inter mode SAD. This invention performs intra mode prediction for only macro blocks have larger inter mode SADs. The definition of a large inter mode SAD differs for different content. This invention compares the inter mode SAD of a current macroblock with an adaptive threshold. This adaptive threshold depends on the average and variance of the SADs of the previous predicted frame. An adaptive threshold is calculated for each new predictive frame.

  • Patent number: 12160566
    Abstract: A prediction mode determining method and apparatus are described. A prediction mode status of a child node of a target node is determined based on an area and a split manner of the target node, where the prediction mode status includes intra prediction mode only and inter prediction mode only. Further, a prediction mode of the child node is determined based on the prediction mode status of the child node. In this way, a same prediction mode is used for all child nodes obtained by splitting the target node. This facilitates pipeline processing of hardware, increases a subsequent processing speed, and improves video coding efficiency.
