Abstract

En diversas modalidades, un administrador de grabación y reproducción de una videograbadora digital (DVR), una caja de convertidor-descodificador, un receptor u otro dispositivo almacena y accede estadísticas en un archivo de estadísticas relacionado a distancias promedio entre tramas de referencia (por ejemplo, intra-tramas o 1-tramas) dentro de bloques de los datos de video de la grabación. Acceder a estas estadísticas durante la reproducción permite al sistema ubicar de manera más precisa tramas de referencia para desplegar mientras se ejecuta la reproducción en una modalidad de trucaje tal como avance rápido, retroceso o salto. La distancia promedio entre las tramas de referencia para un bloque de datos de video particular puede utilizarse para saltar de una trama de referencia a la siguiente trama de referencia en ese bloque durante la reproducción en una modalidad de trucaje.
