Abstract: Cross-plane filtering may be used to restore blurred edges and/or textures in one or both chroma planes using information from a corresponding luma plane. Adaptive cross-plane filters may be implemented. Cross-plane filter coefficients may be quantized and/or signaled such that overhead in a bitstream minimizes performance degradation. Cross-plane filtering may be applied to select regions of a video image (e.g., to edge areas). Cross-plane filters may be implemented in single-layer video coding systems and/or multi-layer video coding systems.

Abstract: This application describes a data transmission method, a network node, and a storage medium for communications technologies. In this application, an underlay segment identifier corresponding to an underlay path is designed, and the underlay segment identifier is advertised, so that a node on a segment routing network can sense the underlay path by using the underlay segment identifier.

Therefore, an underlay path through which a data packet is to be transmitted may be specified based on a service requirement, so that different data packets can be transmitted through different underlay paths, thereby improving flexibility and facilitating traffic planning.

Abstract: This application discloses a network slice information transmission method and apparatus. For example, a controller performs slice division on a network based on a service requirement and then obtains slice information, and sends the slice information to a first network device in the network by using a path computation element protocol (PCEP) packet, which includes first slice information corresponding to the first network device.
