  • Publication number: 20250024046
    Abstract: Methods, apparatuses, and non-transitory computer-readable storage mediums are provided for video coding. In one method, a decoder obtains a first flag in a transform block (TB), a coding block (CB), a slice, a picture, or a sequence level, wherein the first flag indicates whether signaling of inherited intra mode is enabled on a current video block; and in response to determining that the inherited intra mode is enabled on the current video block based on the first flag, the decoder obtains a second flag that indicates whether the inherited intra mode is used at a signaled level.
