Abstract: A direct sequence spread spectrum approach to wireless video transmissions is utilized. This approach provides a lowered spectral power density and also can provide scrambling of the video signal. By providing lower spectral power density the transmitter portion of the invention can operate at higher radio frequency output power levels while remaining in compliance with government regulation for unlicensed use. For example, in the United States, the Federal Communications Commission Part 15 rules allow for higher total conducted output power as long as the spectral power density is limited to +8 dBm for any 3 KHz bandwidth within the allocated band.
