ABSTRACT:
A buffer system for TV receivers includes a cyclic storage device connectible to the demodulation circuits for continuously storing the audio and video signals last outputted thereby only over a predetemined time interval, enabling the viewer to jump-back to see a preceding portion of the TV broadcasts. In one described embodiment, the viewer normally sees the broadcasts in a real-time manner but may depress a button to see the broadcasts in a delayed-time manner via the cyclic storage device. In a second described embodiment, the viewer normally sees the broadcasts in a real-time manner, may depress a button to freeze a part of the broadcast in another storage device, and may later depress another button to play back the portion frozen.
