Abstract

Innovaciones en el área de predicción de valores de vector de bloque ("BV") mejoran la codificación o descodificación de bloques utilizando predicción de copia de intra bloque ("BC"). Por ejemplo, algunas de las innovaciones se refieren al uso de un predictor de BV predeterminado con un valor no cero. Otras innovaciones se refieren al uso de uno seleccionado de múltiples candidatos de predictor de BV para un bloque actual. Otras innovaciones aún se refieren al uso de un modo de salto en el cual un bloque intra-BV predicho utiliza un valor de BC predicho.
