<p>A method that implements low-speed playback of a recorded digital broadcast program in a digital broadcast receiver, comprising the steps of (a) decoding and outputting a received broadcast program consisting of MPEG-encoded I-, P-, and B-pictures, simultaneously recording the received broadcast program, (b) responsive to a request for low-speed playback, extracting only I- and P-pictures from the recorded program and creating alternative pictures for B-pictures, beginning from the start position of the requested playback, (c) inserting intermediate pictures between the pictures in step (b), the number of the created intermediate pictures depending on the requested playback speed, and (d) decoding and outputting the stream of the pictures including the inserted intermediate pictures. The method in accordance with the present invention provides several advantages such as reduced computations and smooth slow motions at very low playback speeds.
