Abstract
Se proporciona un método para decodificar una corriente de bits por medio de un dispositivo electrónico. Una trama de imagen de la corriente de bits es recibida y una unidad de bloque que tiene una anchura de bloque y una altura de bloque se determina a partir de la trama de imagen recibida. El dispositivo electrónico determina si un modo de partición geométrica está deshabilitado para la unidad de bloque con base en una comparación entre la anchura de bloque y la altura de bloque. La unidad de bloque se divide para generar una pluralidad de sub-bloques predichos por diferentes candidatos de fusión de la unidad de bloque cuando el modo de partición geométrica se aplica en la unidad de bloque. El bloque predicho se genera al predecir una unidad de bloque con base en un modo de predicción diferente del modo de partición geométrica cuando el modo de partición geométrica está deshabilitado para la unidad de bloque. La unidad de bloque es reconstruida con base en el bloque predicho.
