Abstract

Se describen técnicas para mejorar la codificación de video. Por ejemplo, se puede obtener un primer bloque de una imagen incluida en un flujo de bits de video codificado. Se puede determinar que un segundo bloque de la imagen está codificado (por ejemplo, codificado) con un tipo de modo de modulación de código de impulsos de dominio residual cuantificado (BDPCM) basado en bloques, como el modo BDPCM vertical o el modo BDPCM horizontal. En caso de que el segundo bloque se codifique utilizando el modo BDPCM vertical, se puede determinar un modo de intrapredicción vertical para una lista de modos de intrapredicción para el primer bloque. El modo de intrapredicción vertical se puede añadir a la lista de modos de intrapredicción para el primer bloque. En el caso de que el segundo bloque se codifique utilizando el modo BDPCM horizontal, se puede determinar un modo de intrapredicción horizontal para la lista de modos de intrapredicción para el primer bloque y el modo de intrapredicción horizontal se puede añadir a la lista de modos de intrapredicción.
