摘要： An interface device to a broadcast medium uses the Internet Protocol communication layer to communicate with other devices on a network. The device may be associated with a single controlling device on the network, through which other devices on the same network may query and schedule the interface device. The interface device may accept several sources of broadcast or other media, including video and audio, and prepare and normalize the content for used by other devices. Several different physical interfaces may be used to subsequently convert the Internet Protocol communications into useful content streams for various devices, including storage and rendering devices.

The entity certificate includes personal credentials, which have information that the entity is unwilling or uncomfortable to share publicly. For example, the personal credentials may include private information, or information associated with a personal object that cannot consume the protected content, or both.
