摘要： Un método para procesar un chorro de datos (110) que consiste en: recibir un chorro de transporte (TS); almacenar al menos una porción del TS, teniendo la referida porción mínima del TS un comienzo y constando de una pluralidad de paquetes TS; determinar, de entre la pluralidad de paquetes TS, al menos un paquete TS que incluya un punto de acceso candidato; almacenar en una memoria de índices (170) una dirección de byte del punto de acceso candidato; y almacenar en la memoria de índices (170) una pluralidad de indicaciones de direcciones de byte, estando asociada cada dirección de byte con un tiempo de llegada de un paquete TS recibido, en el que el TS consiste en un TS parcialmente codificado dotado de una porción de datos codificados (130) y una porción de datos sin codificar (140), y en el que el paso de determinación consiste en: distinguir entre la porción de datos codificados (130) y la porción de datos sin codificar (140); pasar la porción de datos sin codificar (140) para su análisis; y determinar eso que se ha llamado ¿al menos un paquete TS que incluya un punto de acceso candidato¿ basándose en un análisis de al menos parte de la porción de datos sin codificar (140) proporcionada por el paso aprovisionador.

摘要： Apparatus for processing a data stream (110) comprises a data stream receiver (150) operative to receive a transport stream (TS), TS storage apparatus (170) operative to store at least a portion of the TS having a beginning and comprising a plurality of TS packets. The apparatus comprises candidate determining apparatus (190) operative to determine, from among the plurality of TS packets, at least one TS packet comprising a candidate access point, candidate offset storage apparatus (170) operative to store in an index store a byte offset of the candidate access point, and arrival time storage apparatus (170) operative to store in the index store a plurality of indications of byte offset, each byte offset being associated with an arrival time of a received TS packet. The TS comprises a partially scrambled TS having a scrambled data portion (130) and an unscrambled data portion (140), and the data stream receiver (150) also comprises analyzing apparatus (160). The analyzing apparatus is operative to distinguish between the scrambled data portion (130) and the unscrambled data portion (140) and to provide the unscrambled data portion (140) for analysis by the candidate determining apparatus (190). The candidate determining apparatus (190) is operative to determine said at least one TS packet comprising a candidate access point based on examination of at least part of the unscrambled data portion (140) provided by the analyzing apparatus (160).

摘要： Método para procesar un flujo de entrada encriptado basado en paquetes, que comprende datos de vídeo digitales, para producir un flujo de salida parcialmente desencriptado basado en paquetes, donde el método se compone de: recibir una pluralidad de paquetes encriptados en un flujo de paquetes; desencriptar la pluralidad de paquetes encriptados para producir una pluralidad de paquetes desencriptados; para cada uno de los paquetes desencriptados de dicha pluralidad de paquetes desencriptados, llevar a cabo lo siguiente de manera que pueda soportarse la operación en modo de control de movimiento: determinar si dicho un paquete desencriptado se descarta, y de ser así, descartar dicho paquete de la inclusión en dicho flujo de salida; determinar si los cambios se hacen sólo a la cabecera no desencriptada y/o al campo de adaptación de dicho un paquete desencriptado y, de ser así, hacer dichos cambios e incluir en dicho flujo de salida un paquete encriptado a partir de dicho flujo de entrada correspondiente a dicho un paquete desencriptado, en el que el paquete encriptado incluye el campo de adaptación y/o cabecera cambiado; determinar si se hacen los cambios a la carga útil de dicho un paquete desencriptado y, de ser así, hacer dichos cambios a la carga útil para producir un paquete desencriptado modificado e incluir en dicho flujo de salida el paquete desencriptado modificado; y determinar si no se hacen cambios a cualquiera de la carga útil, la cabecera, y el campo de adaptación de dicho un paquete desencriptado y, si no se hacen cambios, incluir en dicho flujo de salida un paquete encriptado a partir de dicho flujo de entrada correspondiente a dicho un paquete desencriptado, y transmitir dicho flujo de salida, comprendiendo dicho flujo de salida por lo menos uno de dichos paquetes desdencriptados y por lo menos uno de dichos paquetes encriptados.

摘要： A method for performing computation tasks in a secure processor, such as a small cards 10 removably connected to a host 15 containing a memory 60. If a real-time task requires processing while a non-real-time task is being processed, a representation of the processing components of the processor is obtained and transmitted to the memory. The real-time task is then executed, after which the representation is retrieved and processing of the non-real-time task continued. Multiple processors, identified by codes, may be used, and processing by a processor only continued if a retrieved task has a code identifying that processor.
