ABSTRACT:
Methods and apparatus are provided for timeshifting audio content in a multiple tuner audio system comprising a first tuner and a second tuner. One operating method involves maintaining a first data storage element for the first tuner, maintaining a second data storage element for the second tuner, receiving first audio content in realtime by the first tuner, and storing data representing the first audio content in the first data storage element, resulting in first stored content. The method also receives second audio content in realtime by the second tuner, and stores data representing the second audio content in the second data storage element, resulting in second stored content. The method thereafter generates a timeshifted audio signal corresponding to the first stored content or the second stored content.
