ABSTRACT:
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 device30with a receiving portion35and a transmitting portion38transmits and receives video data over a communication network10to and from each terminal1–n. A coded video data received from terminals1–n is stored as it is in a first storage portion32and, at the same time, the data converted into specially reproducible video information is stored in the second storage portion33.At the time of reproducing, the reproduction control portion35controls the reproduction selector switch36to obtain the video data from the first storage portion32or the second storage portion33,changing the reproduction mode from ordinary to the rapid forwarding/reversing and vice versa. The specially reproducible video generating portion34successively restores coded video data received through the receiving portion31,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.
