Abstract

Dispositivos y métodos para determinar si se inicia el acceso aleatorio durante la decodificación de la información de video; en un aspecto, un dispositivo puede incluir una memoria configurada para almacenar información de video que incluye al menos un mensaje de información de mejora complementaria (SEI) de punto de recuperación y un procesador acoplado a la memoria; el procesador configurado para determinar si al menos un mensaje SEI de punto de recuperación comprende una indicación para restablecer un valor semántico de conteo de orden de imagen (POC); el procesador además está configurado para identificar al menos una de una primera restricción referente a si el mensaje SEI de punto de recuperación está presente en una unidad de acceso, una segunda restricción referente a una asociación del mensaje SEI de punto de recuperación con una imagen, o una tercera restricción y determinar si se inicia el acceso aleatorio y la decodificación a partir de la unidad de acceso con base, al menos en parte, en una de la primera restricción o la segunda restricción.
