Abstract

La presente descripción se refiere a un método y aparato para el ajuste de la calidad de video basada en un entorno de red; el método incluye: recibir un número de serie del cuadro objetivo de un cuadro de video perdido desde una terminal y usar tiempo cuando se recibe el número de serie del cuadro objetivo como un sello de tiempo del número de serie del cuadro objetivo; determinar el número de los números de serie del cuadro objetivo correspondiente al sello de tiempo dentro de un período de tiempo predefinido; bajar un parámetro de calidad designado según un criterio de configuración predefinido cuando el número de números de serie del cuadro objetivo es superior a un primer umbral; o aumentar el parámetro de calidad designado según el criterio de configuración predefinido cuando el número de números de serie del cuadro objetivo es menor que un segundo umbral, el primer umbral siendo mayor que el segundo umbral; las soluciones técnicas de la presente descripción aseguran que una cámara inteligente ajusta los parámetros de calidad de video según un entorno de red actual y así asegurar que una terminal puede reproducir uniformemente un video.
