1. An audio-visual system for a facility, comprising:
- a video camera in one of a plurality of classrooms;
an encoder for receiving video content from said camera and encoding said video content into a digital stream, said encoder connected into said network in the one of the plurality of classrooms;
a decoder also connected into said network, said decoder adapted to receive said digital stream and transform said digital stream into an analog signal which is playable to a plurality of video display devices in said facility;
an override mechanism connected to said network that activates the video content for display on a predesignated number of the plurality of video display devices in said facility in response to a first selection of the override mechanism, the override mechanism being operable to activate the video camera and the encoder to capture the video content in real-time in response to the first selection; and
a controller adapted to determine a plurality of states for a plurality of ports communicating media content to a plurality of video display devices from a plurality of media players in said facility in response to the first selection of the override mechanism, store the plurality of states for each of the plurality of ports and the plurality of media players, pause playback for each of the plurality of ports, communicate the video content to each of the plurality of ports communicating with the plurality of video display devices, and return the plurality of ports and associated plurality of media players to the plurality of states in response to a second selection of the override mechanism, wherein the controller controls the plurality of media players utilizing infra red signals.

Abstract
A system and method using digital technologies to deliver a live-video-all-call bulletin over a local area network (LAN) in a facility, e.g., a school. The live video overrides all the facility'"'"'s video-player devices by pausing them. Once the live-feed-video presentation is over, the system returns all of the facilities video players to the same state of operation each was in before the all-call presentation began.

11. A method of enabling a live audio-visual presentation in a facility, comprising:
-
receiving a user selection of a switch in communication with a camera and a digital encoder; determining a plurality of states of a plurality of ports communicating media content from a plurality of media players to a plurality of displays in the facility in response to the user selection; storing the plurality of states for the plurality of ports; pausing playback to the plurality of displays from the plurality of media players; entering a video-all-call state on all of the plurality of ports in communication with the plurality of displays; activating the camera and the digital encoder to capture video content in real-time in response to determining the plurality of states; converting the video content received from the camera in real-time into a digital stream utilizing the digital encoder; communicating the digital signal to a decoder; converting the digital signal to an analog signal in the decoder for communication to the plurality of displays in the facility through a network; displaying the analog signal on the plurality of displays; and returning to the stored plurality of states for each of the plurality of ports communicating media content to the plurality of displays from the plurality of media players in response to another selection of the switch. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A device for causing the display of a live audio-visual presentation in a school facility, comprising:
-
a digital encoder useable with a camera and includable in a facility computer network; said encoder adapted to receive real-time video content from said camera in real-time and encode the real-time video content into a digital stream within one of a plurality of classrooms in the school facility; a switch of said encoder, said encoder being adapted such that when said switch is activated, a video-all-call signal is transmitted which interrupts current media playing on the network and replace said media playing with the real-time video content included in said digital stream; and a controller in communication with the encoder through the facility computer network, the controller being operable to manage a state of operation for a plurality of media players in the school facility, determine the state of operation for the plurality of media players in response to the switch being activated, provides the encoder a status of each port corresponding to the plurality of media players, pause playback of media content to the plurality of displays, store the status of each of a plurality of ports and commands the controller to return to the status including playback of the media content in response to another selection of the switch, the controller managing communication of the real-time video content to each of the plurality of displays in communication with the controller through the plurality of ports. - View Dependent Claims (19, 20, 21)

22. An audio-visual control system for use in a facility comprising:
-
a video camera network throughout the facility; a video-camera interface for communicating with a video camera over an IP network; a switch component for activating the video camera; an encoder component for converting video content received from the video camera to a digital signal communicated through the IP network of the facility; a data storage medium for storing a state of operation of said media-player device for later retrieval in response to a first selection of a switch associated with the video camera and the encoder to enter a video-all-call mode, wherein media playback for the video output is paused during the video-all-call mode; a transmitting component for transmitting commands to a plurality of media player device; a decoder component for converting the digital signal to an analog signal; a video output for playing the analog signal of video content received from said camera over at least one display device, the analog signal being communicated through a cable network; and a state-return system for returning said media-player device to said state of operation in response to a second selection of the switch. - View Dependent Claims (23, 24, 25, 26)
