Abstract: Display assemblies for supporting displays on stands or support arms have mount portions to removably attach to the displays using magnetic assemblies and latches. The magnetic assemblies and latches can improve user experience and allow the display to be installed on a support arm from the viewing side of the display and without having to see or reach behind the display. Magnetic structures can center a mount portion of the support arm and a recess of the display and can attract them to each other. Laterally-extending latches can ensure the display is not inadvertently removed. Locking mechanisms can prevent the display from being rotated to a portrait orientation when sufficient space around the display and the necessary user intent is not provided.

Abstract: In a method of point cloud attribute decoding in a point cloud decoder, a sorting method of a set of points of a point is determined. A quantization parameter for quantizing transform coefficients of a Haar-based attribute coding of the point cloud is determined based on first signaling information in a coded bitstream of the point cloud. The Haar-based attribute coding is configured to perform point cloud compression on the set of points of the point cloud based on a Haar transform. An entropy decoding method for decoding the quantized transform coefficients is determined according to the quantization parameter that is determined based on the first signaling information. The quantized transform coefficients are further determined based on the entropy decoding method. Attributes of the point cloud are reconstructed based on the determined sorting method and the determined quantized transform coefficients.
