Abstract

A multimedia client/server system, prior to transmitting multimedia data over an RF communication link, shares secure access data between the client module. The secure access data is used to securing communication between the server transceiver module and the client transceiver module over the RF communication link.

Claims (12)

1. A multimedia client/server system comprising:

a multimedia server, coupleable to a plurality of multimedia sources that produce at least one multimedia signal, the multimedia server including:

an encoder module that encodes the at least one multimedia signal to produce an encoded signal; and

a radio frequency (RF) server transceiver module, coupled to the encoder module, that produces a channel signal that includes the encoded signal and that wirelessly transmits the channel signal in a regular power mode, the RF server transceiver module including a server secure access module that secures the channel signal based on secure access data, wherein the RF transceiver module enters a low power mode during a channel setup procedure between the multimedia server and a client and wherein the RF transceiver module transmits the secure access data to the client in the low power mode, during the channel setup procedure and prior to transmitting the channel signal; and

the client, coupleable to at least one client device, the client including:

an RF client transceiver module that receives and demodulates the channel signal to produce a received encoded signal, the RF client transceiver module including a client secure access module that accesses the channel signal based on the secure access data; and

a decoder module, coupled to the RF client transceiver module, that decodes the received encoded signal into a decoded output signal.

2. The multimedia client/server system of claim 1 wherein the secure access data includes one of a password and an encryption key.

3. The multimedia client/server system of claim 1 wherein the secure access data is transmitted by the multimedia server to the client by the RF server transceiver module after the RF server transceiver module is automatically set in the low power mode.

4. The multimedia client/server system of claim 1 wherein the encoder module encodes the at least one multimedia signal in accordance with one of a Motion Picture Experts Group (MPEG) standard, and a Society of Motion Picture and Television Engineers (SMPTE) standard.

5. The multimedia client/server system of claim 1 wherein the RF server transceiver module and the RF client transceiver module communicate over a broadband wireless access network that conforms to at least one of the following standards: 802.11x, Ultra Wideband (UWB), and Worldwide Interoperability for Microwave Access (WiMAX).

6. The multimedia client/server system of claim 1 wherein the encoder module transcodes the at least one multimedia signal.
