Abstract

Las innovaciones en el área de codificación o decodificación de los bloques usando la predicción intracopia de bloque mejoran la eficacia de codificación para los bloques previstos intra-BC en muchas condiciones. Por ejemplo, algunas de las innovaciones se refieren a la inversión de bloque en la cual un bloque previsto intra-BC se invirtió con relación a una región de referencia, que puede indicarse por un valor de vector de bloque. Otras innovaciones se relacionan con la señalización de un modo de omisión en el cual un bloque actual previsto intra-BC usa un diferencial de BV señalizado, pero carece de los datos residuales.
