Abstract: Methods and systems for using text data in content presentation and content search are disclosed. Text data and a plurality of video frames can be extracted from a content program and stored in a database. Extracted text data can be divided into a plurality of text segments. The plurality of text segments and the plurality of video frames can be presented in the form of an electronic book or guide. In addition, the content program can be divided into a plurality of content segments and stored in the database. The plurality of content segments and the plurality of text segments can be associated by time indices. A user can identify one or more content segments in the database by a query, and notifications can be sent according to the query.

Abstract: Access devices may receive signals over a network and calculate a frequency spectrum of the received signals. An analyzer system may collect the frequency spectrum data from multiple access devices, and based on the collected data, detect, identify, and locate sources of anomalies in a communication network.

Abstract: System and methods for inferring network topology are described, including a method comprising determining a normalized transmit power of a first device, identifying a second device based upon a parameter of the second device and the normalized transmit power of the first device, and generating a topology including the first device and the second device based upon at least one of the normalized transmit power of the first device and the parameter of the second device.
