Abstract: Methods and systems for content presentation optimization are disclosed. A content and/or service provider can receive a data sample relating to a content item presented via a device. One or more configuration settings to be applied to the device can be determined based on the data sample. The one or more determined configuration settings of the device can be automatically or manually adjusted. In an aspect, a content and/or service provider can receive a content item from a content presentation device. The received content item can be analyzed against reference data. A modified content item can be generated based on the analysis. The modified content item can be transmitted to the content presentation device for content presentation.

Abstract: A fault detection system is provided for detecting and locating faulty connections in a cable TV system. First and second signals are generated at the head end transmitter. The first signal is a continuous wave signal. The second signal is a pulse modulated sine wave signal. A fault is indicated by the reception of a beat frequency signal between the first and second signals generated at the location of the faulty connection and returned to the head end. The location of the fault is determined by measuring the time interval between the transmission of the first and second signal and the return of the beat frequency signal, and relating such time interval measurement to the corresponding distance between the head end and the faulty connection.
