Abstract

Un vector de bloque de componente croma se inicializa utilizando uno de un vector de bloque luma colocado o aledaño cuando el modo de referencia de imagen actual se utiliza y cuando el árbol dual es habilitado. En una primera modalidad, si el bloque de luminancia colocado no es codificado en el modo de referencia de imagen actual, un vector luma de un sub-bloque croma izquierdo se utiliza. Cuando el sub-bloque croma izquierdo no es codificado en el modo de referencia de imagen actual, un vector luma de un sub-bloque croma izquierdo, Cuando el sub-bloque croma izquierdo no es codificado en el modo de referencia de imagen actual, un vector luma del sub-bloque croma anterior se utiliza, y si no está disponible, un vector predeterminado es utilizado. En una segunda modalidad, una división de bloque luma colocado se utiliza para derivar un vector de bloque croma.
