Abstract: Methods and apparatus for enhancing connectivity for a device backhauled by a wireline communication network. In one embodiment, the device comprises a small-cell or other wireless base station that is backhauled by a DOCSIS system within a managed HFC network, and the method and apparatus enable enhanced connection of user devices serviced by the base station (such as 3GPP UE or CBRS FWA) to a core entity for e.g., authentication and packet session establishment. In one implementation, enhanced Cable Termination System (CMTS) and cable modem (CM) devices coordinate to allocate prioritized service flows to traffic sourced from the base station. These service flows can selectively bypass extant DOCSIS protocols which might otherwise increase connection latency (including connection failure) such as AQM (active queue management) and packet dropping algorithms. In some variants, upstream service flow data rates can also be enhanced through temporary utilization of higher-order modulation and/or coding schemes.

Abstract: The present invention provides a system for frequency modulation of high definition composite video broadcast signals in a wireless transmission environment and a method thereof, comprising: a transmitting unit and a receiving unit. An image sensor of the transmitting unit converts an image to a digital signal. A signal processor converts the digital signal to a composite video broadcast signal. A frequency modulator modulates the composite video broadcast signal to a first modulated signal. The receiving unit receives the first modulated signal. A low noise amplifier converts the first modulated signal to a second modulated signal. A frequency demodulator restores the second modulated signal to the composite video broadcast signal. After an image decoder decodes the composite video broadcast signal, the image decoder outputs a digital signal in a specific format.
