Abstract

Se proporciona un método para ofuscar el código de programa para impedir que usuarios no autorizados accedan al vídeo. El método incluye recibir un código de programa original que proporciona funcionalidad. Se transforma el código de programa original en el código de programa ofuscado definiendo una versión codificada de ramificación aleatorizada del código de programa original. Entonces se almacena el código de programa ofuscado, y un procesador que recibe el flujo de datos de vídeo de entrada utiliza el código de programa ofuscado para generar un flujo de datos de salida.
