The master content player publishes synchronization commands to a synchronization server accessed through a wide area network and the slave content player utilizes the wide area network to access the synchronization server for the synchronization commands. The first visual content on the first digital display is coordinated in a predetermined manner with the second visual content on the second digital display on a segment-by-segment basis. ## Claims ### Claim 1 A system, comprising: a first digital display; a master content player configured to supply first visual content to the first digital display; a second digital display; and a slave content player configured to supply second visual content to the second digital display; wherein the master content player publishes synchronization commands to a synchronization server accessed through a wide area network and the slave content player utilizes the wide area network to access the synchronization server for the synchronization commands, such that the first visual content on the first digital display is coordinated in a predetermined manner with the second visual content on the second digital display on a segment-by-segment basis. ### Claim 2 (depends on 1) The system of claim 1 wherein each segment of the first visual content has a pre-assigned synchronization identification and each segment of the second visual content has a corresponding pre-assigned synchronization identification. ### Claim 3 (depends on 1) The system of claim 1 wherein each of the first visual content and the second visual content is a composition comprising an arrangement of visual components selected from text, images, videos and animations. ### Claim 4 (depends on 3) The system of claim 3 wherein each of the first visual content and the second visual content is a program comprising a series of compositions. ### Claim 5 (depends on 1) The system of claim 1 wherein the slave content player stores alternate visual content and invokes the alternate visual content in response to an incorrect synchronization parameter. ### Claim 6 (depends on 5) The system of claim 5 wherein the alternate visual content is selected from a fallback program, a previous program and a next program. ### Claim 7 (depends on 1) The system of claim 1 wherein the master content player coordinates the publication of synchronization commands in response to dynamic input. ### Claim 8 (depends on 7) The system of claim 7 wherein the dynamic input is from a sensor. ### Claim 9 (depends on 7) The system of claim 7 wherein the dynamic input is from a digital device. ### Claim 10 (depends on 7) The system of claim 7 wherein the dynamic input is a monitored parameter on a networked device. ### Claim 11 (depends on 1) The system of claim 1 wherein the synchronization server re-synchronizes video content for multiple digital displays on a faster-than-frame basis. ### Claim 12 (depends on 1) The system of claim 1 wherein the synchronization server publishes a synchronization status indicative of the proximity of a frame of first visual content on the master content player to a corresponding frame of second visual content on the slave content player. ### Claim 13 (depends on 12) The system of claim 12 wherein the slave content player selectively jumps to a proximate frame in response to the synchronization status. ### Claim 14 (depends on 1) The system of claim 1 wherein the synchronization server supports a cropping tool to allow a user to crop individual segments of a frame and assign the individual segments a common synchronization identification such that the individual segments are simultaneously displayed on the first digital display and the second digital display. ### Claim 15 A system, comprising: a master to control an audio and visual experience; and a plurality of slaves controlling a plurality of individually controlled audio devices and visual devices selected from a projector, a light, a digital display, a sign, and a speaker; wherein the master publishes synchronization commands to a synchronization server accessed through a wide area network and the slaves utilize the wide area network to access the synchronization server for the synchronization commands, such that the audio and visual experience is coordinated in a predetermined manner by the plurality of slave devices on a segment-by-segment basis, wherein each segment is a specified setting for the individually controlled audio devices and visual devices. ### Claim 16 (depends on 15) The system of claim 15 wherein each segment has a pre-assigned synchronization identification. ### Claim 17 (depends on 15) The system of claim 15 wherein the master content player coordinate the publication of synchronization commands in response to dynamic input. ### Claim 18 (depends on 17) The system of claim 17 wherein the dynamic input is from a sensor. ### Claim 19 (depends on 17) The system of claim 17 wherein the dynamic input is from a digital device. ### Claim 20 (depends on 7) The system of claim 7 wherein the dynamic input is a monitored parameter on a networked device.
