In one example, for a given intra-predicted block, a reduced number of transform unit partition options is allowed, based on certain conditions. In another example, transform units are decoupled from prediction units for intra-predicted block. For a given prediction unit, transforms of different sizes and shapes from the prediction unit may be applied. In another example, a reduced number of intra-prediction modes are allowed for a prediction unit having a non-square shape."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-square transform units and prediction units in video coding","description":"This disclosure proposes techniques for transform partitioning in an intra-prediction video coding process.
