摘要:
A system and method for providing access to a communication network includes providing a radio node comprising a first set of access point components including a radio component, and providing a physically separated controller node in communication with the radio node. The access point controller comprises a second set of access point components distinct from the first set of access point components, creating a distributed access point. A system controller may also be used to control at least one of the radio node and the controller node. The radio node, the controller node, and the system controller communicate over a communication link, such as a wireless or wired link.

A method for processing an analog video signal that represents a work for which rights information is asserted. The signal includes a rights assertion mark (RAM) in the video portion of the signal within the visible picture such that capture of the picture will include the mark. The signal also includes copy control information (CCI) bits in the vertical blanking interval of the signal for representing copying and redistribution rules. If the RAM is present and the CCI bits are present, then the copying and redistribution rules represented by the CCI bits are applied. If the RAM is present but the CCI bits are not, then the most restrictive copying and redistribution rules that can be represented by the CCI bits are applied.

A system and method for virtual linking a wireless device to another device is disclosed herein. The system includes an access point and a controller configured to mediate transmissions between the wireless device and the another device. The system further includes a virtual device table and a permissions filter to ensure virtual linking between devices that have matching access right and requested services. The wireless device and the another device may have the same or dissimilar protocols.

VEIL modulation is a method of “subliminal” encoding of data in a video image that is similar to a watermark. The encoding consists of alternately proportionately raised and lowered luminance on selected horizontal scan lines. The encoding can be detected using a notch filter centered at half the line frequency. The encoding is lost, however, if the resolution of the video signal is changed downward. The invention preserves the encoding by coding alternate groups of lines, not alternate lines. This allows detection with a notch filter even after a reduction in resolution.

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.

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.
