The video encoding system determines and applies a transform operation to residuals of one or more transform blocks to generate final transform coefficients, and skip signaling a secondary transform index if a position of a last significant coefficient in each considered transform block is less than or equal to a predefined position; otherwise, the video encoding system signals a secondary transform index according to the transform operation. The video decoding system parses last significant coefficient position syntax of each considered transform block to determine a position of a last significant coefficient, and infers inverse secondary transform is not applied if the positions of the last significant coefficients are less than or equal to the predefined position; otherwise, the video decoding system determines an inverse transform operation by parsing a secondary transform index."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatuses for coding video data with adaptive secondary transform signaling","description":"Video processing methods and apparatuses implemented in a video encoding or decoding system with conditional secondary transform signaling.
