摘要
A radio or television apparatus has tuning circuitry for selecting a channel from an input spectrum, an output for presenting a presentation from a selected channel, a recording apparatus having a memory with capacity for recording a fixed time duration T of the selected presentation, and adapted to make an audio record sequentially in a circular fashion, such that when the memory capacity is filled, the device continues to record, overwriting the oldest recorded information, providing thereby, at any point in time, a stored copy of time duration T immediately preceding the point in time. This innovation provides limited rewind capability for real-time data streams. In alternative embodiments add-on devices are provided for existing radios and TVs.
