Powerline Communication Wi-Fi Camera Authentication And Video Transmission
A power and communication transmission arrangement includes an electronic accessory having a first modulator/demodulator. A motor vehicle includes a charging system to provide a power signal to the electronic accessory. At least one electrical conductor carries the power signal from the charging system to the electronic accessory. An infotainment system bi-directionally communicates with the electronic accessory. A second modulator/demodulator modulates the power signal based upon first signals received from the infotainment system to form first modulated power signals such that the first modulator/demodulator demodulates the first modulated power signals to extract the first signals for use in the electronic accessory. The first modulator/demodulator modulates the power signal based upon second signals from the electronic accessory to form second modulated power signals such that the second modulator/demodulator demodulates the second modulated power signals to extract the second signals for use in the infotainment system.
