ABSTRACT:
A method for communicating data, such as audio/video (AV) data, over plural channels involves selecting data and encryption information, and encrypting the data with the encryption information to thereby produce encrypted data. The encryption information is broken into portions. The encrypted data is communicated by way of at least one of the plural channels, and at least some portions of the encryption information are communicated over at least one channel other than that one over which the encrypted data is communicated. In a more general case, the encrypted data is sent over one channel, and the encryption information is divided and sent over several other channels.
