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.

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.

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 Sor to apply IIR filtering for the vertical filtering where the determined scale factor satisfies a second condition relative to the threshold value S. 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.

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.

Intelligent resource state memory recall

An audio and video production system and method, including a video production control switcher; and one or more computers connected through a network and configured for controlling the video production control switcher. 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.

A method, system, and device for generating a clean clipping signal &#x3b1; for a chromakey function or a video composition, including identifying background colors formed by a solid color background, shadows cast by still and moving subjects, a non-uniform reflection caused by spot lighting and non-flat backdrop or flaw wall, and translucent foreground objects, with a 3D volume in a 3D color space; determining parameters defining same by using a dirty alpha &#x3b1;; generating a clean clipping signal &#x3b1;background colors, and a clean clipping signal &#x3b1;for translucency colors; identifying foreground colors formed by the still and moving subjects with a 3D volume in a 3D color space; classifying colors into transition colors; and generating an area map for mapping each pixel into background, shadow, translucent, foreground, and transition areas.

Method, system, and device for automatic determination of nominal backing color and a range thereof

A personal digital assistant (PDA) enabled telephony system is provided comprising a telephone set having a communication port and a personal digital assistant. The personal assistant includes a user interface for displaying telephony functions to a user; a detector for detecting a selected telephony function; a telephony application for determining a call command based on the selected telephony function; and a communicator for communicating said call command to the communication port. In response to receiving the call command, the telephone set executes the selected telephony function.

The present invention is directed at hybrid network configuration, comprising a plurality of application platforms for sending and receiving at least one of voice and data in accordance with a first predetermined protocol, a voice/data network for routing the voice and data between the plurality of application platforms in accordance with a second predetermined protocol, and at least one network portal for providing the plurality of application platforms access to the voice/data network using the first and second predetermined protocols.

Transport protocols for application platforms over network portals

A video production switcher converts an aspect ratio through the use of an integrated aspect ratio converter. Additionally, by having both converted and native format signals input to a switcher processor, the effective number of inputs can be doubled.

Multi-keying circuitry for inserting a plurality of keys into a background television signal where at least the keying signal processing circuitry is time shared by control circuitry to effect the key insertions. The control circuitry includes dual port rams and RAM-DAC's to facilitate the time share operation. Circuitry for effecting transitions between the keys either individually or in groups is disclosed as is circuitry for previewing the keys or the transitions thereto either individually or in groups.
