Abstract

Se presenta un sistema y método para modificar características de tolerancia a error mediante la transmision de índices de imágenes de nivel temporal 0, tal como t10 pic-idx, dentro de un mensaje SEI en lugar de incluirlos optativamente en el encabezado de unidades NAL. Además, se presenta un mecanismo para habilitar la repeticion de cualquier mensaje SEI en paquetes de Protocolo de Transporte en Tiempo Real (RTP). La habilitacion de dicha repeticion de posibles mensajes SEI facilita la deteccion de las imágenes perdidas de nivel temporal 0 sobre la base de los posibles paquetes recibidos.
