The video encoding device may partition the N/2 by N array of residual values for the chroma component into two N/2 by N/2 sub-arrays of chroma residual values. The video encoding device may further partition the sub-arrays of chroma residual values based on the partitioning of the array of residual values for the luma component. Video encoding device may perform a transform on each of the sub-arrays of chroma residual values to generate transform coefficients. A video decoding device may use data defining sub-arrays of transform coefficients to perform a reciprocal process to generate residual values."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transform unit partitioning for chroma components in video coding","description":"A video encoding device is configured to obtain an N by N array of residual values for a luma component and a corresponding N/2 by N array of residual values for a chroma component.
