Abstract
Una modalidad de la invención establece un servidor de codificación que incluye componentes configurados para codificar un flujo de video asociado con un título de contenido para flujo adaptativo. El flujo de video es primero procesado por un codificador VC1 para generar un flujo de video codificado que comprende GOP múltiple, cada GOP incluye un marco clave y que tiene un desfase de reproducción diferente. El flujo de video codificado es luego empacado de tal manera que los GOP se almacenan en paquetes de datos del flujo codificado empacado. Un generador SHI genera un SRI asociado con un flujo codificado empacado que incluye un punto de conmutación asociado con cada GOP. Cada punto de conmutación incluye un desfase de reproducción asociado con el GOP correspondiente y el paquete de datos que almacena el cuadro clave del correspondiente GOP. El SRI asociado con múltiples flujos de video codificados empacados asociados con el mismo título de contenido y codificado a diferentes velocidades de bit de reproducción tiene puntos de conmutación correspondientes.
