Abstract: Input video data of sequential GOPs (Group of Pictures) coded according to MPEG (Moving Picture Experts Group) standard is edited. The edition is conducted at least at a first edition point and a second edition point of the input video data. The second edition point comes after the first edition point on the time-axis. In the case where the first edition point is located in the midway of a first GOP, decoded are at least a first data portion of the first GOP, the first data portion ranging from the head of the first GOP to the first edition point, and a first entire data of a second GOP followed by the first GOP. On the other hand, in the case where the second edition point is located in the midway of a third GOP that comes after the first GOP on the time-axis, decoded are at least a second data portion of the third GOP, the second data portion ranging from the second edition point to the end of the third GOP, and a second entire data of a fourth GOP that follows the third GOP.

Abstract: A control circuit causes a reproducing transducer feeding motor to move the transducer radially across a disc having a video signal recorded thereon. The video signal is recorded along a spiral track, together with first, second, and third reference signals which control the transducer tracking. A feed pulse forming circuit forms a number of feed pulses according to the number of switching pulses which are generated due to the reproduction of the third reference signal. A number of kick pulses are required for shifting the reproducing transducer element from one track turn to another track turn as it moves toward a center of the rotary recording medium, with the movement occurring at a position where the third reference signal is recorded. The control circuit causes a rotation of the motor for moving the reproducing transducer along the radial direction of the disc, according to the number of feed pulses that are obtained from the feed pulse forming circuit.
