Abstract

La presente descripción se refiere a un método y un dispositivo para reproducir un archivo multimedia. El método incluye: enviar un primer paquete de datos de audio a un dispositivo de reproducción de audio y enviar un primer paquete de datos de video a un dispositivo de reproducción de video, cada uno del primer paquete de datos de audio y el primer paquete de datos de video porta un identificador de prueba de datos; devolver una primera marca de tiempo por el dispositivo de reproducción de audio, si el dispositivo de reproducción de audio recibe el identificador de prueba de datos; devolver una segunda marca de tiempo por el dispositivo de reproducción de video si el dispositivo de reproducción de video recibe el identificador de prueba de datos; enviar un segundo paquete de datos de audio del dispositivo de reproducción multimedia al dispositivo de reproducción de audio y enviar un segundo paquete de datos de video del dispositivo de reproducción multimedia al dispositivo de reproducción de video respectivamente de acuerdo con la primera marca de tiempo y la segunda marca de tiempo, para que se reproduzca sincronizadamente el segundo paquete de datos de audio y el segundo paquete de datos de video. De esta forma puede solucionarse un problema de datos de audio y datos de video asíncronos durante la reproducción del archivo multimedia.
