Abstract: Systems and methods are provided for adaptive linearization of an amplifier system having a plurality of heterogeneous amplifier paths. An amplifier system includes a plurality of amplifier paths, each configured to provide an amplified output signal from an input signal, and a signal combiner configured to combine the amplified output signals from the plurality of amplifier paths to provide a system output, such that the system output is a non-linear function of the amplified output signals. A monitoring system is configured to sample the system output and normalize the sampled output to a signal level associated with the input signal. A signal processing component is configured to characterize the amplifier paths via an iterative adaptive linearization process, such that the system output is linear with respect to the input signal.

The multiviewer video processor may permit scrolling among the multiple video windows displayed on the display at a given instant and at least one other video window not displayed on the display at the given instant based upon the at least one user input device.

Abstract: Systems and methods are provided for calibrating a transmitter system. A directional coupler is configured to provide a first signal representative of a forward power of an RF signal and a second signal representative of a reflected power of the RF signal. A splitting assembly is configured to generate respective third and fourth signals, each representative of the forward power, from the first signal. A switching assembly is configured to select between the second signal and the third signal. A system control is configured to determine an associated power of each of the fourth signal and a signal provided by the switching assembly.

Specifically, disclosed are systems and/or methods for creating a smart channel tuner list, including determining an identity of a user interacting with a content presentation system, collecting channel switching information from the first channel to each of a plurality of second channels from the user's interaction with the content presentation system, determining a value for each of the plural second channels as a function of the channel switching information, and creating a smart channel tuner list as a function of the determined value.

Abstract: Systems and/or methods are disclosed herein to identify a user interacting with a content presentation system, adaptively learn, in a passive manner, a user's pattern of accessing content over time, and globally store the user's identifying and use information. Specifically, disclosed are systems and/or methods for switching from a first signal provided to a second signal, including identifying a user of a first content presentation system, creating a first preferred channel list which includes channel information for each of select ones of plural signals, where the preferred channel list is created based on the identity of the user and based on channel use information for the user during a recurring first time period, presenting substantially simultaneously to the user a first signal of the select ones of plural signals in a first frame and a second signal of the select ones of plural signals in a second frame.

Abstract: A video multiviewer system may include a plurality of video scalers operating in parallel for generating initially scaled video streams by performing video scaling in at least one dimension on a plurality of video input streams. The video multiviewer system may also include at least one video cross-point switcher coupled downstream from the video scalers, and a processing unit coupled downstream from the video cross-point switcher for generating additionally scaled video streams by performing additional video scaling on the initially scaled video stream. The video scalers and the processing unit may communicate through the video cross-point switcher using a serial digital interface.

Abstract: A system for synchronizing unrelated information or reference signals originating from multiple sources. The signals may be in different signal formats or subject to different delays at a receiving device. The system may include a master reference time generator connected to at least one of a plurality of slave reference signal generators via a packet network. The master reference time generator may include a master reference time counter and a sampling device for sampling the master reference time counter. The master reference time generator may encode time data in master reference time packets and feed these packets into the packet network. The slave reference signal generator(s) is adapted to accept the encoded time data as an input to generate a reference signal, the phase of which is calculated based on the time elapsed since an initial time point.
