Abstract: A production system automates the control of production devices used to produce and broadcast a show. The system automation allows a video director to pre-produce, preview, and produce the live show from a single user interface. In an embodiment, a processing unit displays graphical controls for the production devices. A video director interacts with the graphical controls to thereby remotely control the production devices from one location. In an embodiment, a video director defines a set of production commands or instructions (i.e., “transition macro”). Upon execution, each production command directs the processing unit to transmit in series and/or parallel one or more control commands to one or more of the production devices. Production commands can be included to enable the show to be broadcast live or recorded for on-demand access. Live and/or on-demand productions are distributed over traditional television mediums and/or a computer network, including the Internet.

Abstract: A video production system provides a director with-control over video production devices used in producing a show. The video production system allows the director to pre-produce a show, review the show in advance of “air time.” and then, with a touch of a button, produce the live show. The video production system includes a processing unit in communication with the video production devices. The processing unit displays controls for controlling the video production devices. The director uses a keyboard and mouse to remotely control the video production devices. The director pre-produces the show, defines a set of video production commands (hereafter “transition macro”) executed by the processing unit. By activating a control button, the director instructs the processing unit to execute the transition macro-to control one or more of the video production devices.

Abstract: An integrated, fully automated video production system that provides a video director with total control over all of the video production devices used in producing a show. Such devices include, but are not limited to, cameras, robotic pan/tilt heads, video tape players and recorders (VTRs), video servers and virtual recorders, character generators, still stores, digital video disk players (DVDs), audio mixers, digital video effects (DVE), video switchers, and teleprompting systems. The video production system provides an automation capability that allows the video director to pre-produce a show, review the show in advance of “air time,” and then, with a touch of a button, produce the live show. In one embodiment, the invention provides a video production system having a processing unit in communication with one or more of the video production devices mentioned above.

Abstract: The temperature of air leaving a cooling coil is monitored for dropping below various threshold values. The number of cooling stages which chill the refrigerant flowing through the cooling coil is first reduced when the temperature drops below a first threshold and continues to drop relative to a previously sensed temperature. Damper positions governing the amount of air flowing to zones to be cooled are thereafter adjusted when the temperature continues to drop relative to a previously sensed temperature. All adjusted positions are at least maintained relative to a calculated offset value until the temperature rises above a second threshold value greater than the first threshold value. All cooling stages are turned off if the sensed temperature drops below a third threshold value lower than the first threshold.

Abstract: The temperature of the air leaving a heating coil is monitored for rising above a first threshold temperature value. An offset value is calculated for use in the positioning of each damper associated with a zone that is to be heated by air leaving the heating coil when the temperature of the air leaving the heating coil rises above the first threshold value. The offset value for each damper position is maintained until the temperature of the air leaving the heating coil drops below a second threshold temperature lower than the first threshold temperature. Any additional heating sources which also heat the air flowing over the heating coil are turned off immediately if the temperature of the air leaving the cooling coil rises above a third threshold value that is higher than the first threshold value.

Abstract: A process for noting in advance when a change in set point temperature is to occur in one or more zones. A heating stage is prematurely activated and dampers are selectively opened in the one or more zones that are about to experience changes in set point temperature. Activation of a second stage of heating is not permitted unless the zone temperature is lagging the current set point.

Abstract: A bypass damper for a forced air system comprising a freely pivotable damper blade with bent portions at the ends thereof and having an adjustment mechanism for adjusting the pressure set point of the damper.
