Zusammenfassung: | 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
30
with a receiving portion
35
and a transmitting portion
38
transmits and receives video data over a communication network
10
to and from each terminal
1
-n. A coded video data received from terminals
1
-n is stored as it is in a first storage portion
32
and, at the same time, the data converted into specially reproducible video information is stored in the second storage portion
33.
At the time of reproducing, the reproduction control portion
35
controls the reproduction selector switch
36
to obtain the video data from the first storage portion
32
or the second storage portion
33,
changing the reproduction mode from ordinary to the rapid forwarding/reversing and vice versa. The specially reproducible video generating portion
34
successively restores coded video data received through the receiving portion
31,
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. |
