Abstract

Se presentan innovaciones en predicción de copia intrabloque ("BC") así como también innovaciones en los patrones de búsqueda de codificador lateral y enfoques para particionar. Por ejemplo, algunas de las innovaciones se refieren al uso de las particiones asimétricas para predicción de copia intrabloque. Otras innovaciones se refieren a los patrones de búsqueda o los enfoques que usa un codificador durante la estimación del vector de bloque (para predicción de copia intrabloque) o estimación de movimiento. Incluso otras innovaciones se refieren al uso de rangos de búsqueda BV que tienen un sesgo horizontal o vertical durante la estimación del BV.
