Abstract

Varias técnicas para limitar el número de bins que son codificados usando un modelo de contexto adaptativo con la codificación aritmética binaria adaptativa del contexto (CABAC). En particular, limitar el número de bins que usan CABAC para codificar la información de nivel de los coeficientes de transformación en un proceso de codificación de vídeo.
