Abstract

En un ejemplo, aspectos de esta divulgación se refieren a un método para codificar datos de video que generalmente incluye determinar información de predicción para un bloque de datos de video, donde el bloque está incluido en una unidad codificada de datos de video y colocado debajo de una fila superior de bloques vecinos de arriba en la unidad codificada, y donde la información de predicción para el bloque está basada en la información de predicción de uno o más bloques diferentes en la unidad codificada pero no está basada en información de predicción de ninguno de la fila superior de bloques en la unidad codificada; el método generalmente también incluye codificar el bloque con base en la información de predicción determinada.
