Zusammenfassung:The present invention relates to a video storage type communication system and more particularly to a video storage type communication device which is capable of successively decoding received coded video data by video decoding means, encoding the decoded video frame/field (hereinafter simply referred to as frame) only in intraframe mode by coding means and stored in a center storage device, thereby realizing the possibility of generating pictures specially reproducible, for example, with rapid feeding. A device which is capable of storing moving picture data received from each terminal and providing each terminal with video information to be reproducible by rapidly forwarding or reversing at any desired speed independent of usable terminals. A video storage type communication device with a receiving portion and a transmitting portion transmits and receives video data over a communication network to and from each terminal -n. A coded video data received from terminals -n is stored as it is in a first storage portion and, at the same time, the data converted into specially reproducible video information is stored in the second storage portion At the time of reproducing, the reproduction control portion controls the reproduction selector switch to obtain the video data from the first storage portion or the second storage portion changing the reproduction mode from ordinary to the rapid forwarding/reversing and vice versa. The specially reproducible video generating portion successively restores coded video data received through the receiving portion encodes again the restored data by intraframe, interframe or still-picture coding method to generate video information to be reproducible in special mode such as reproduction by rapid forwarding or reversing.
