A moving picture compressed signal changeover apparatus changes over from a first moving picture compressed signal containing intra-frame coded frames, forward prediction coded frames and bidirectional prediction coded frames to a second moving picture compressed signal containing intra-frame coded frames, forward prediction coded frames and bidirectional prediction coded frames such that a frame of the first moving picture compressed signal occurring just before an intra-frame coded frame or a forward prediction coded frame of the first moving picture compressed signal is connected to an intra-frame coded frame of the second moving picture compressed signal. A predetermined signal which is different from the first and second moving picture compressed signals may be inserted between the connected frames of the first and second moving picture compressed signals. Alternatively, at least one of the first and second moving picture compressed signals may be delayed so as to adjust a connecting timing.
