Abstract
A time shifting device receives a full broadcast band, such as the FM radio band, demodulates the received full broadcast band into each component broadcast channel, and stores the program signal received from each broadcast channel in a buffer, thereby enabling continuous time-shifting of the content without requiring any prior program pre-selection. The disclosed time shifting device includes an analog to digital converter which digitizes an analog broadband radiofrequency signal, which may include some or all allocated broadcast channels of the targeted broadcast band, into a digital broadband radiofrequency signal. A digital filter and demodulation circuit demodulates the digitized broadband signal into individual datastreams corresponding to the various broadcast channels contained in the broadcast band. The datastreams are stored in a circular buffer for selective playback by a user. Program metadata may be utilized to identify and select programs for playback.
