Abstract
Las modalidades de la presente divulgación proveen un método de codificación de coeficiente, un codificador, un decodificador, y un medio de almacenamiento de computadora; el método incluye lo siguiente; una corriente de bits se analiza sintácticamente para obtener una bandera de video; cuando la bandera de video indica que un video satisface una condición preestablecida, la corriente de bits se analiza sintácticamente para obtener una bandera de posición inversa del último coeficiente significativo e información de coordenada de un último coeficiente significativo; cuando la bandera de posición inversa del último coeficiente significativo indica que se invierte una posición del último coeficiente significativo para un bloque actual, se determina la posición del último coeficiente significativo mediante cálculo con la información de coordenada del último coeficiente significativo; de acuerdo con un orden de escaneo preestablecido, todos los coeficientes antes de la posición del último coeficiente significativo se decodifican para determinar los coeficientes del bloque actual; como tal, el rendimiento y velocidad de codificación de codificación del coeficiente pueden mejorarse mientras se mejora la eficiencia de compresión en los escenarios de codificación de video con alta profundidad de bit, alto flujo de datos, alta calidad, o compresión con menos pérdida.
