摘要： A technique is provided for securely transferring programming content from a first device in a first layer, e.g., a trusted domain, to a second device in a second layer, e.g., outside the trusted domain. When a user requests that the first device transfer protected content to the second device, the first device needs to authenticate the second device. After the second device is authenticated, the first device may transfer to the second device the protected content, together with a rights file associated therewith. The rights file specifies the rights of the second device to use the protected content, according to its security level indicative of its security. These rights may concern, e.g., the number of times that the second device may subsequently transfer the protected content to other devices, the time period within which the second device may play the protected content, etc.; The higher the security level of the second device is, the more rights accorded thereto. Indeed, the second device may need to meet a minimum security level requirement in order for it to receive or keep the protected content.

摘要： A method of operating a cable network having a plurality of legacy-capable CPE and a plurality of wideband CPE operatively coupled thereto, the method comprising: distributing at least one first program comprising a plurality of content elements, said act of distributing comprising sending said content elements over multiple carriers of said network; and providing program information data as part of said distributing such that said wideband CPE can receive and decode said at least one first program, said program information being structured so as to preclude said legacy-capable CPE from decoding said first program.

摘要： Methods and apparatus for centralized content, media and data delivery and access within a premises such as, e.g., a residence. In one embodiment, the apparatus comprises a remotely manageable premises device that acts as a centralized client networking platform, providing gateway services such as network management as well as traditional content and high-speed data delivery functions. The device also acts as the shared internet connection for all devices in the premises via a cable modem, sharing personal and DVR content such as video, music and photos (and any associated metadata) throughout the premises, and providing both a wired and wireless network in the home. Telephony services utilizing e.g., embedded multimedia terminal adapter (eMTA) and/or Wi-Fi architectures may also be provided via the device. The device can also provide a trusted domain for content or data, as well as allowing a subscriber total mobility in the home.
