Apparatus reproducing signals on slow reproduction
A digital video cassette recorder reproduces signals which have been compressed to digital data and recorded in predetermined M tracks (M&gE;1) with helical scan in the unit of page consisting of N frames (N&gE;1). Further, position data have been added to the digital data on recording. On reproduction, the position data are detected to determine which reproduction position is reproduced, and a control signal to designate a field to be output is generated by observing the reproduction position during a frame period. A first storage device stores decoded data in the unit of N frames, while a second storage device delays the data a time of one field. By observing the reproduction situation with the position data, a memory controller controls reading from the first storage device according to the control signal, while a switch selects data to be output between data from the first storage device and data from the second storage device according to the control signal.
