A multimedia client/server system includes a multimedia server module that is coupleable to a plurality of multimedia sources that produce at least one multimedia signal. The multimedia server module includes an encoder module that asserts a protection present signal when the at least one multimedia signal includes a copy protection signal, that generates an output signal with the copy protection signal removed when the protection present signal is asserted, and that encodes the output signal to produce an encoded signal. A server transceiver module produces a radio frequency (RF) signal that includes the encoded signal and the protection present signal, and that wirelessly transmits the RF signal. A client module includes a client transceiver module that receives and demodulates the RF signal to produce a received encoded signal and a received protection present signal, and a decoder that decodes the received encoded signal into a decoded output signal that includes the copy protection signal when the received protection present signal is asserted.
