A television production system affords simplification over the automation of a television program such as a news program by making use of State Memory Objects (S-MEMs), each defining one or more operations for execution by one or more production devices. The S-MEMS serve to control one or more actuators on a control panel so that each actuator on the control panel can control different function of different pieces of production equipment depending on the S-MEM selected, and the actuator manifests a status of the production device.

In general, various methods, apparatuses, and systems are described for communicating a loss of an AC power source. In at least certain embodiments, a broadband communication gateway receives a direct current (DC) output signal from an alternating current (AC) to DC converter that detects a loss of an AC input signal. The apparatus further includes a processing unit that generates a communication message in response to receiving an interrupt signal based on the detection of the loss of the AC input signal. The processing unit controls an analog front end that sends the communication message to a device external to the broadband communication gateway in response to the interrupt signal prior to a voltage of the DC output signal decreasing below a threshold voltage needed for operation of the broadband communication gateway.

Various methods, apparatuses, and systems in which a residential gateway is located at the network interface device and is powered with a remote power source inside the residence. In another embodiment, bi-directional data communication between the residential gateway and the remote power source is also enabled.

A method of concealing temporal shifts when a digital video effects system is used with a video switcher adds a mixer to the digital video effects system to mix the input to and output from the digital video effects system if the image to be transformed is on-screen at the beginning of the effect. An input video signal from a keyer in the video switcher is switched by an effects send/return matrix to the inputs of the digital video effects system and the mixer, and the output from the mixer is returned to the effects send/return matrix for input to the mix/effects stage of the video switcher. When the digital video effects system is bypassed, a delay circuit is used in the bypass path of the effects send/return matrix, the delay time equaling the processing time of the mixer.

A graphic display for chroma keyer controls presents background hue as a radial spoke of an outer chroma vector circle, with selectivity being displayed as a wedge about the radial spoke. Foreground suppression may be added to the graphic display by providing a concentric inner chroma vector circle with the foreground suppression hue being a radial spoke of the inner circle and foreground selectivity being a wedge within the inner circle about such radial spoke. That portion of the outer circle that is overlapped by the inner circle is suppressed, or rendered invisible, so that the background chroma information appears as a torus about the inner chroma vector circle.
