    摘要: Enhanced multimedia content on physical media interacts with the user through a media player and the Internet. Enhanced multimedia utilizes IDs for pieces of content on the media and a media key block. On the enhanced media is a file with a list of URLs. As the enhanced media plays a title requiring an external permission for decryption, the media player accesses the URL for that title and obtains the permission. The permission may be purchased or provided for free. Secure encryption and transmission of permission is accomplished by broadcast encryption using a media key block. Each media has a unique set of keys that allow the media player to process the media key block; however, each media follows a unique path through the media key block. All legitimate media players obtain the media key; circumvention devices cannot decipher the media key block.

    摘要: Disclosed embodiments include a method performed by a network access point, such as a short-range wireless communications switch or Bluetooth base station unit, to provide a neighbor list for neighboring short-range wireless communications switches or network access points in a communications network. The method includes, at the short-range wireless switch, sending at least one signal to neighboring wireless devices, wherein sending the signal is done without assistance of a mobile unit or a system controller for the communications network. The method further includes receiving a response signal from at least one neighboring short-range wireless switch, and identifying the one neighboring short-range wireless switch based on the received response signal. Additionally, the method includes providing a neighbor list that identifies the one neighboring short-range wireless switch. Numerous alternative embodiments are also described.

    摘要: Content is distributed from a source to a sink only if the sink is within a predetemined distance from a source. In one embodiment, a control signal is sent over a limited range channel to the sink and the content is then sent only if the control signal is received properly by the sink. In another embodiment, the content is encrypted and the encryption key is sent over the limited range channel. The content is also sent to the sink, but the sink cannot decode the content unless it has a proper copy of the decoding key. The control signal can be sent over a wireless channel, an IR channel, or an AC line. The content is sent over the Internet, either using a standard wired channel or over a wireless channel.
