RESTORATION OF FREQUENCY-DEPENDENT SIGNAL LOSS IN A FULL-DUPLEX DOCSIS DIRECTIONAL COUPLER
A system may comprise a transmitter associated with a content delivery network. The system may comprise a Full Duplex DOCSIS (FDX) coupler. The FDX coupler may be configured to receive, from the transmitter, at least one first signal, cause sending of the at least one first signal to at least one client device, receive, from the at least one client device, at least one second signal, and cause sending of the at least one second signal to a receiver associated with the content delivery network. The FDX coupler may cause a frequency-dependent signal loss associated with the at least one first signal to minimize signal loss through the coupler and maximize output power transfer. The transmitter may be configured to adjust a transmit power associated with the at least one first signal to inversely correspond to the frequency-dependent signal loss.
A system may provide supplemental content to a viewer of a content item through use of an embedded identifier indicating an address of associated supplemental content identifying data. The supplemental content identifying data may identify one or more supplemental content items associated with the content item and available to the viewer. An address or other identifier in the supplemental content identifying data may be used to retrieve at least a portion of the available supplemental content items, and a display may be generated combining the content item with the supplemental content. In some embodiments, the identifier may be securely provided to a client and may be authenticated as part of retrieving supplemental content associated with the content item. The identifier may comprise a trusted token or security token used to authenticate the supplemental content identifying data associated with the content item.

Wireless communications are described for access procedures. A wireless device may use a plurality of identifiers to monitor for a response from a base station. The wireless device may determine whether a random access procedure is a success or a failure based on the identifier that the wireless device is able to use to receive the response.
A text detection process may involve comparing high-contrast pixel densities of areas of images of a video to determine quantities of text-containing areas in the images. Based on a difference between quantities of text-containing areas of subsets of the images, an image of the video may be selected for modification.

Systems and methods are for content security may comprise transmitting a request for authorization to access secured content. A content key for the secured content may be received and stored to a restricted region of a memory. A device security module may have access to the restricted region and may decrypt, based on satisfaction of a use condition and using the content key, the secured content. An encryption key associated with a secure media system authorized to access the secured content may be received. The device security module may encrypt, using the encryption key, the secured content and route the secured content to the secure media system.
Systems and methods for provisioning and managing resources are disclosed. Methods can comprise determining whether a first condition is met based upon a first characteristic relating to one or more of a user device and a first network device. Association between the user device and the first network device can be granted if the first condition is met; association can be denied otherwise. Service can be provided to the user device via the first network device if the first network device is configured to meet a second condition. The second condition can be based upon a second characteristic relating to one or more of the user device and the first network device. The user device can be caused to associate with a second network device if the first network device is not configured to meet the second condition.
