Abstract: This disclosure provides systems, methods and apparatus for providing user selected IP Data Network Protocol multi-media content via a CATV communication channel. In one example, a method of providing multi-media content includes receiving control data at a cable television provider server system from an controller device at an end-user location via an IP Data Network, the controller device having a display screen, a user interface, and at least one processor, and being configured to send and receive signals from the IP Data Network, where the control data indicating multi-media content to be provided by the provider system to a display system at the end-user location.

Abstract: A method for tracking an incrementally sweeping generator by a frequency selective receiver is disclosed. A sequence of test signals is generated each of which has a discrete and different frequency which is periodically and incrementally modified according to a program, and the dwell time of each frequency is sufficient to obtain at least two receiver measurements. This sequence of test signals is supplied to a device under test, and the output signals from the device under test are fed to the frequency selected receiver which operates at one of the discrete frequencies supplied according to the program. The operating frequency of the receiver is modified according to the same sweep program and with at least the same sweep rate. The levels of at least two consecutive measurements at the receiver output are compared with at least one reference value which is selected such that it discriminates against other signals that are not part of the sweep program.
