摘要： Systems and methods for implementing a Transport I/O system are described. Network encrypted content may be received by a device. The device may provide the network encrypted content to a secure processor, such as, for example, a smart card. The secure processor obtains a network control word that may be used to decrypt the network encrypted content. The secure processor may decrypt the network encrypted content to produce clear content. In embodiments, the secure processor may then use a local control word to generate locally encrypted content specific to the device. The device may then receive the locally encrypted content from the secure processor and proceed to decrypt the locally encrypted content using a shared local encryption key. The Transport I/O system ensures the protection of the network control word by maintaining the network control word on the secure processor.

摘要： Systems and methods are disclosed for performing anti-piracy countermeasures in order to prevent unauthorized access of protected content. A conditional access system may be modified to include a counter. The counter is incremented every time the conditional access system receives a request that is a potential indication of pirate activity. The counter may also be decremented every time the conditional access system receives a request indicative of legitimate activity. If the conditional access system receives a management message containing a key required to access content keys, the conditional access system checks the counter. If the counter is below a threshold value, the conditional access system obtains the key. However, if the counter is above the threshold value, the conditional access system disregards the key contained in the management message, thereby losing access to protected content.

摘要： The various examples described herein generally provide systems and methods for generating a hybrid electronic programming guide (EPG) that includes both broadcast content and other types of content, such as over-the-top (OTT) content. In examples, broadcast content may be content provided by a satellite, terrestrial, or cable television provider. Other types of content, e.g., the OTT content, may be content that is delivered over an open network, such as the Internet. In examples, a secure processor may be employed to determine if a subscriber is authorized to access the OTT content based on subscription information received via a broadcast transmission.

摘要： Systems and methods are disclosed to facilitate the reception, processing, outputting, and communication of content from one or more sources. Content is stored on a digital video recorder and a content storage server. The digital video recorder exchanges metadata with the content storage server that indicates the specific content stored on the digital video recorder. A communication device may request access to the content stored on the content storage server. The content storage server determines if the communication device is associated with a digital video recorder that is storing the requested content. If the communication device is associated with a digital video recorder storing the requested content, the content storage server sends the requested content stored on the content storage server to the communication device.
