  • Patent number: 12219125
    Abstract: A method of constraining the operations of certain inter-mode coding tools in the derivation of motion vector candidates for inter-mode coded blocks employed in video coding standards, such as the now-current Versatile Video Coding (VVC), is performed at a computing device. The computing device determines whether one or more of the reference pictures associated with an inter-mode coded block involved in an operation of an inter-mode coding tool are long-term reference pictures, and constrains the operation of the inter-mode coding tool on the inter-mode coded block based on the determination.
