Abstract: A secondary satellite radio or broadcast channel is used to broadcast advertisement clips (e.g., audio clips) to a receiver for subsequent decoding and playback. The receiver is configured for different tiers of service, e.g., one that delivers substantially advertising-free content and another that delivers content that includes more significant amounts of advertising. The content delivered to both is the same content; however, for the service tier that includes more advertising, the advertisements broadcast on the secondary channel are interleaved into the content, preferably in such a way that the continuity of the content being delivered is not compromised.

Abstract: A receiver comprises an input circuit that receives an input signal. An error circuit generates an error signal based on the input signal. A first noise canceler generates a first noise cancellation signal based on the error signal. A second noise canceler generates a second noise cancellation signal based on the error signal. The input circuit is responsive to the second noise cancellation signal.
