Abstract: Detecting the presence of a television signal embedded in a received signal including the television signal and noise. Either first-order or second order cyclostationary property of the signals may be used for their detection. When the first-order cyclostationary property is used, the received signal is upsampled by a factor of N, a synchronous averaging of a set of M segments of the upsampled received signal is performed, an autocorrelation of the signal is performed; and the presence of peaks in the output of the autocorrelation function is detected. When the second order cyclostationary property of the signal is used, the received signal is delayed by a fixed delay (symbol time), the received signal is multiplied with the delayed version, and a tone (single frequency) in the output is detected.

Abstract: A system and methods to provide imaging service using outdoor lighting networks. The system uses outdoor lighting networks to manage/control video/image sensors connected to the network, e.g. hosted at lighting units, and coordinates the capture of useful video/image data associated with events. The system also provides an information search platform for users to retrieve only the relevant video/image data associated with events of interest. Furthermore, the system controls when and how to retrieve video/image data at lighting units across the whole network according to user requests, the priority of the events, and available bandwidth.
