Abstract: The Monte-Carlo method of generating Popcorn shooting patterns starts with the number and sizes of the guns available and the length in time of the desired Popcorn pattern. The firing times and order of the guns will be randomly perturbed and a large number of Popcorn patterns built. Candidate Popcorn patterns will then be tested against a set of criteria to identify acceptable or the best patterns. These criteria may include limits on maximum peak strength, distinctiveness compared to the other patterns, and the size of the notches and peaks in the spectra.

Abstract: Low-latency interactive multiviewer interfaces and methods for video broadcast equipment are disclosed. A video switcher includes an integrated multiviewer to generate a multiviewer interface. Video signals are received from video sources and a user interface graphic is received from an external source such as an external computer. The received video signals are routed in a video path of the video switcher to be presented in a multiviewer interface on a display, and the received interface graphic is overlaid on the received video signals for presentation in the multiviewer interface. Realtime elements associated with frames of the video signals may also be generated within the video switcher and combined with the video signals and the externally generated interface graphic in the multiviewer interface. The video signals could include video signals from external video sources, outputs of internal processing elements within the video switcher, and/or intermediary video signals within the video switcher.

Abstract: The maximum output of a seismic source array may be reduced by activating the individual seismic sources within these seismic source array in a pattern that is extended in time rather than by the presently employed conventional simultaneous activation of a large number of individual seismic sources. Methods are disclosed which take data shot with patterned sources and may use a sparse inversion method to create data with the about same image quality as that of conventional sources. In this manner the output of the maximum impulse of a seismic source array may be reduced by an amplitude factor of about 10 in the examples shown here, corresponding to a reduction of about 20 dB while maintaining virtually the same seismic image quality. The disclosed methods may be used in combination with any simultaneous sourcing technique. In addition, the disclosed methods may be used with a plurality of source arrays.

Abstract: Video/audio production processing control synchronization apparatus and methods are provided. Processing control commands that are provided to a first installation of production processing equipment for controlling production processing of edit units of first production signals are echoed to another installation, or possibly multiple other installations, of production processing equipment. Timing information associated with the edit units is also provided to the other installation(s), to enable production processing of delayed production signals by the other installation(s) to be synchronized with the production processing by the first installation of production processing equipment. Multiple production processing equipment installations can be controlled and synchronized from a single control interface.

Abstract: Various improvements for video production switchers are disclosed. In a user input module, a Link button is operable to link key functions with a user controllable input device. A multicolor lighting arrangement may be provided, and possibly calibrated, for illuminating each button of a switcher with a controllable color and/or intensity. In an improved Pulse-Width Modulation (PWM) scheme, a PWM output is dependent on a pseudo-random number and a threshold. A display on a keyer module may be used to provide indications of a key source and type currently associated with the keyer module. A switcher menu system may be enhanced by providing a first display for accessing a full menu system, and a second display for accessing at least a portion of the full menu system. In a modular switcher panel, a panel structure carries button modules, at least one of which is interchangeable without displacing other button modules.

Abstract: Apparatus and methods for electronic hardware resource management in video processing are provided. A hybrid filter is controllable to apply either Finite Impulse Response (FIR) filtering or Infinite Impulse Response (IIR) filtering for vertical filtering of a video image during a resizing process. A scale factor by which the video image is to be resized in the resizing process is determined, and the hybrid filter is controlled to apply FIR filtering for the vertical filtering where the determined scale factor satisfies a first condition relative to a threshold value ST or to apply IIR filtering for the vertical filtering where the determined scale factor satisfies a second condition relative to the threshold value ST. The first and second conditions are different and exclusive, such that only one type of filtering is applied. This hybrid filtering approach uses each type of filtering to avoid defects of the other.

Abstract: Intelligent resource state memory recall techniques, and associated apparatus and methods, are disclosed. States of one or more video switcher resources in a resource state memory may be recalled to the same or different resources, depending on resource availability at the time of memory recall. A memory recall need not affect an on air signal. The memory may be recalled to recreate a desired program output, as defined in the memory, on a preview output of the video switcher, which leaves a current program output of the video switcher undisturbed when the memory is recalled.

The system is further configured for at least one of defining looks, including shot templates, that correspond to particular settings on the production control switcher or settings of parts of the production control switcher; defining sequences of the looks or assigning individual looks to control elements on a computer of the computers; transmitting the looks across the network; and translating of a single look into one or more standard editor commands, and transmitting the commands to the production control switcher.

Abstract: According to a preferred aspect of the instant invention, there is provided a system and method for using satellite communications satellites to control and receive data from a land cableless seismic system. The satellite transmission could transmit control signals (e.g. turn on/off) and receive signals from the remote seismograph units (seismic data, quality control parameters, status, location, etc.) which would subsequently be retransmitted to a processing center or other surface facility.

Abstract: According to a preferred aspect of the instant invention, there is provided herein a system and method for creating low frequency seismic waves. In brief, the instant invention uses a rotary propeller-type system that has been mounted in, for example, a barge or other marine vessel as a seismic source. In the preferred arrangement, the instant source will generate a seismic signal that has greater low frequency content (e.g., frequencies that are less than about 10 Hz) than has been possible heretofore.
