  • Publication number: 20210144388
    Abstract: Techniques for implementing video processing techniques are described. In one example implementation, a method of video processing includes determining, for a conversion between a current block of a video and a bitstream representation of the video, whether a combined inter and intra prediction (CIIP) coding technique is to be applied to the current block based on a characteristic of the current block. The CIIP coding technique uses an intermedia inter prediction value and an intermedia intra prediction value to derive a final prediction value of the current block. The method also includes performing the conversion based on the determining.

    Abstract: Techniques for implementing video processing techniques are described. In one example implementation, a method of video processing includes determining, for a conversion between a current block of a video coded using a combined inter and intra prediction (CIIP) coding technique and a bitstream representation of the video, an intra-prediction mode of the current block independently from an intra-prediction mode of a neighboring block. The CIIP coding technique uses an intermedia inter prediction value and an intermedia intra prediction value to derive a final prediction value of the current block. The method also includes performing the conversion based on the determining.

  • Publication number: 20210144392
    Abstract: Techniques for implementing video processing techniques are described. In one example implementation, a method of video processing includes determining, for a conversion of a block of a video that is coded using an inter-intra prediction coding technique and a bitstream representation of the video, a prediction value at a position in the block based on a weighted sum of an inter prediction value and an intra prediction value at the position. The weighted sum is based on adding an offset to an initial sum obtained based on the inter prediction value and the intra prediction value. The offset is added prior to a right-shift operation performed to determine the weighted sum. The method also includes performing the conversion based on the determining.

  • Publication number: 20210127366
    Abstract: The present invention relates to an allocation technology for wireless network resources, and particularly to a resource allocation method for coexistence of multiple line topological industrial wireless networks. The present invention considers the coexistence problem of multiple TDMA-based line topological industrial wireless networks, including three parts: lower bound analysis of scheduling delay, allocation algorithm of inter-network resources and allocation algorithm of intra-network resources. The method uses overall scheduling delay and resource utilization ratio as measurement indexes when analyzing the lower bound of delay and designing resource allocation algorithms, and selects a best node combination in each time slot to occupy as many channel resources as possible to improve the resource utilization ratio and reduce the overall scheduling delay.
