Abstract: A system for recording and playing back data and a karaoke satellite radio receiver and related systems and methods, the recording/playback system includes: (1) a buffer, (2) a recorder controller configured to intercept a data stream during operation of the receiver and store a portion of the data stream in the buffer and (3) a playback switch configured to receive a command that causes the recorder controller to substitute the portion stored in the buffer for the data stream flowing from the demodulator. The latter system includes: (1) a demodulator configured to receive a data channel, (2) a channel selector configured to select at least the channel, (3) a visual display configured to display at least accompanying text and (4) a text manager configured to extract the text from the channel and cause the visual display to display the text in coordination with audio being played by the receiver.
