Abstract

Innovaciones en opciones de lado de codificador para modo de predicción de copia de intra bloque ("BC") facilitan la predicción de intra BC que es más efectiva en términos de desempeño de distorsión por velocidad y/o eficiencia computacional de codificación. Por ejemplo, algunas de las innovaciones se refieren a la estimación de valores muestra dentro de un área de traslape de un bloque actual durante la estimación de vector de bloque. Otras innovaciones se refieren a la predicción de los valores de vector de bloque ("BV") durante la codificación o descodificación utilizando los aspectos de "ping-pong".
