Abstract:     Method and apparatus for synchronizing performance of audio, lighting, animation, and special effects programs at a plurality of remote locations, such as on parade floats, in which the programs are stored at each location as digitally-encoded information in the memory of one or more controllers, and DTMF tone bursts are transmitted over a selected radio frequency as a synchronization signal to each remote location for controlling synchronous performance of the programs by audio, lighting, animation, and special effects systems on the floats. The DTMF tones control retrieval from an audio controller of an audio program and a SMPTE time code signal for synchronous control of the lighting, animation, and special effects systems. The DTMF tone bursts are divided into timecode packets of discrete tones that are transmitted approximately every 700 milliseconds, wherein the first tone is a special control tone for synchronization, followed by several location tones, and the last tone is used to verify a valid timecode packet order.

First Claim:
Show all 34 claims
I claim:     1. A method of synchronizing performance of a plurality of remote location programs at a plurality of remote locations, comprising:
  • (a) storing, with a controller, programs in memory at predetermined memory address locations at each of the plurality of remote locations, at least one of said programs located at corresponding memory address locations at each remote location being different from the other programs, each of said programs being stored as digitally-encoded information;
  • (b) transmitting a synchronization signal to each of the remote locations over a predetermined radio frequency with the use of a transmitter, said synchronization signal identifying a memory address within said predetermined memory address locations at the plurality of remote locations;
  • (c) receiving said synchronization signal on said predetermined radio frequency at each of the remote locations with a receiver; and
  • (d) retrieving simultaneously with a controller at each of the plurality of remote locations said digitally-encoded program information, in response to said synchronization signal, for synchronous performance of the programs at the plurality of remote locations.
