Abstract
Algunos aspectos de la divulgación proporcionan un método y un aparato para la codificación de vídeo. En algunos ejemplos, un aparato incluye circuitos de procesamiento para decodificación de vídeo. El circuito de procesamiento decodifica información de predicción de un bloque actual a partir de un flujo de bits de vídeo codificado. La información de predicción es indicativa de un modo de copia intrabloque. El circuito de procesamiento selecciona, de un conjunto de múltiples resoluciones candidatas, una resolución de una diferencia de vector de bloque para el bloque actual, y determina un vector de bloque del bloque actual de acuerdo con la resolución seleccionada de la diferencia de vector de bloque y un predictor de vector de bloque de el bloque actual. Luego, el circuito de procesamiento reconstruye al menos una muestra del bloque actual según el vector de bloque. (Traducción automática con Google Translate, sin valor legal)
