Abstract

Un aparato de codificación de video anexa la demora de decodificación y la información de corrección de demora de despliegue a los datos de video codificados con el objeto de asegurar que incluso cuando una o más imágenes que son posteriores al orden de codificación que una imagen codificada de inicio en una corriente de datos de video a ser empalmada a un extremo de rastreo de otra corriente de datos de video codificados se ha descartado de entre las imágenes contenidas en la corriente de datos de video, la imagen codificada de inicio y sus imágenes subsiguientes pueden ser decodificados en forma continua y desplegadas por un aparato de decodificación de video; la información de corrección es calculada con base en un intervalo de decodificación entre cada imagen descartada y una imagen que precede en forma inmediata a la imagen descartada; el aparato de decodificación de video corrige la demora de decodificación y la demora de despliegue de la imagen codificada de inicio y sus imágenes subsiguientes utilizando la información de corrección calculada.
