Abstract
Receivers using multiple tuners may introduce crosstalk between signals provided to the tuners. The disclosed embodiments relate to a method and apparatus for detecting and preventing crosstalk. A method is described that includes providing a signal to a first signal processing path, tuning to a channel in the signal provided through the first signal processing path, tuning to the channel in the signal through a second signal processing path, and determining that crosstalk exists if the channel is present on the second signal processing path. An apparatus is also described containing means for providing a signal to a first signal processing path, tuning to a channel in the signal provided through the first signal processing path, tuning to the channel in the signal through a second signal processing path, and determining that crosstalk exists if the channel is present on the second signal processing path.
